    I. Performance & Surveillance

    District Reporting Completeness

    Bulletin Analysis

    National reporting completeness for week 13 was successfully maintained at a commendable 97.0% across the country. This consistent performance indicates that the vast majority of our health facilities have integrated digital reporting into their weekly clinical routines. High completeness is essential for ensuring that the Ministry of Health has a comprehensive view of the national disease burden without significant regional gaps. When nearly all facilities report, the statistical power of our epidemiological models increases, allowing for more precise resource allocation. We must acknowledge the dedicated work of the district IDSR coordinators who have pushed for this level of compliance. This data provides the backbone for all subsequent public health decisions made at the central level this week. Maintaining this trajectory is vital as we conclude the first quarter of the 2026 reporting cycle.

    Despite these achievements, the 3% gap in completeness represents several dozen facilities that are currently invisible to our national surveillance network. These “silent” facilities may be harboring localized outbreaks of cholera or measles that could spread undetected to adjacent communities. It is imperative that Zonal Epidemiology Officers conduct targeted site visits to identify the specific technical or human resource barriers at these sites. We have observed that facilities in remote areas often struggle with consistent internet connectivity, necessitating alternative offline reporting solutions. Every facility that fails to report compromises the integrity of our national “Early Warning” system and creates unnecessary public health risks. We aim to reach a 100% completeness target by providing additional training to the identified lagging districts in the coming month. Surveillance is a collective responsibility that requires every single node in the network to function at peak capacity. Strengthening these weak links will ensure that no Malawian is left outside the protection of our surveillance system.

    Timeliness Performance

    Bulletin Analysis

    Timeliness for week 13 was recorded at 95.0%, representing a slight but notable decrease from the previous week’s performance levels. Reporting on time is critical because public health actions are most effective when they are initiated within hours of an event’s detection. A report that arrives late effectively delays the national response, potentially allowing a single case of disease to become a cluster. The 95% rate suggests that most facility focal persons are adhering to the Monday morning deadline despite heavy clinical workloads. We must emphasize that data loses its operational value rapidly as time passes, making punctuality a key quality metric. The One Health Surveillance Platform (OHSP) is designed for real-time interaction, but its utility depends entirely on the speed of data entry. We commend those districts that achieved 100% timeliness this week despite facing significant logistical and environmental challenges.

    Analysis of the 5% delay reveals that specific districts are consistently struggling to validate their data before the national submission cutoff time. District Health Officers must streamline their internal validation processes to ensure that errors are corrected quickly without holding up the entire report. We recommend that facilities establish “Data Mondays” where reporting is prioritized as a primary clinical duty before mid-day. PHIM will begin publishing a “Timeliness League Table” to foster healthy competition and transparency among the reporting districts. Improving timeliness by just a few percentage points can significantly enhance our ability to contain rapidly spreading enteric diseases. We are also exploring the implementation of automated SMS alerts to remind focal persons of the approaching deadlines. Our goal is to institutionalize a culture of “Real-Time Surveillance” where data flows as fast as the pathogens we are tracking. Let us all recommit to the Monday deadline to ensure our national defense against disease remains agile and responsive.

    EBS Signal Distribution

    Bulletin Analysis

    During week 13, thirty-four (34) Event-Based Surveillance (EBS) signals were detected, of which twenty-four (24) were successfully verified by district teams. This verification rate of approximately 70.6% indicates that while community reporting is high, there is a significant lag in the official confirmation process. It is critical that every signal reported by the community is prioritized for rapid field assessment within 24 hours of notification. The 34 reported signals show that our community health surveillance assistants are active and vigilant in identifying unusual health clusters. However, the ten signals remaining unverified represent potential blind spots in our national health security framework. Each of these unverified reports could potentially be the early indicator of an emerging cholera or viral outbreak. We must improve the speed and documentation of verification to ensure that resources are not wasted on false alarms. The verification process is the bridge between raw community intelligence and a coordinated medical response.

    District Rapid Response Teams (DRRTs) must account for the ten unverified signals and ensure they are processed before the start of week 14. We recommend that districts with backlogs in signal verification re-evaluate their communication protocols between community volunteers and clinical supervisors. A signal is only as useful as the investigation it triggers; without verification, a report cannot lead to meaningful public health action. We are implementing new digital tracking tools in the OHSP to help coordinators monitor the “time-to-verification” for all community-level alerts. High verification rates are essential for maintaining the credibility of the EBS system among community stakeholders and donors alike. We will provide additional logistical support to the three districts with the highest volumes of unverified signals this week. Our target is to achieve a 100% verification rate for all signals to ensure that no legitimate threat is left unexamined. Strengthening this verification loop is a primary goal for the National IDSR Secretariat as we move into the next quarter. Consistent follow-through on every community alert will build the trust necessary for a truly collaborative national surveillance network.

    II. Disease Morbidity

    Malaria Trends (Week 13)

    Bulletin Analysis

    Malaria continues to dominate the national morbidity profile with 31,233 cases and 10 reported deaths in week 13 alone. This high case volume is characteristic of the late rainy season where stagnant water provides optimal breeding conditions for Anopheles vectors. The 10 deaths reported this week are a significant concern and represent the highest weekly mortality for malaria in this quarter. Each death should be audited at the facility level to determine if there were delays in the administration of injectable artesunate. We must also analyze whether these deaths were concentrated among children under five or pregnant women, who remain our most vulnerable cohorts. The consistent burden of malaria places a massive strain on our primary healthcare system and essential medicine supply chains. Surveillance data suggests that transmission intensity is particularly high in the lake-shore and southern region districts this week. Targeted interventions must be prioritized in these high-burden ecological zones to prevent further loss of life.

    The National Malaria Control Program must ensure that all health facilities have an adequate supply of Rapid Diagnostic Tests and ACTs to handle this influx. Community health workers should intensify their efforts to promote the consistent and correct use of Long-Lasting Insecticidal Nets (LLINs) in every household. We are also advocating for a high index of clinical suspicion for severe malaria complications, such as cerebral malaria or severe anemia, in all febrile patients. Early treatment within 24 hours of fever onset is the most effective way to reduce the progression to severe, fatal disease. We encourage districts to use this surveillance data to plan for indoor residual spraying (IRS) campaigns in identified hotspots. Public health education must emphasize that malaria is a preventable and curable disease if identified and managed in time. We will continue to monitor these trends closely to ensure that our national response remains proactive rather than merely reactive. It is essential that we move beyond simple case counting to active, data-driven prevention at the community level. Every malaria death is a tragedy that can be avoided with timely intervention and proper resource management.

    Rabies Surveillance

    Bulletin Analysis

    Rabies surveillance in week 13 recorded fifteen (15) animal bite cases requiring post-exposure prophylaxis (PEP) across the country. While no human deaths were reported this week, the steady stream of animal bites highlights the persistent threat of this 100% fatal but preventable disease. Each reported bite must be treated as a medical emergency, necessitating the immediate administration of the rabies vaccine. We have observed that many facilities struggle with maintaining a consistent supply of PEP, leading to dangerous delays for victims. This week’s data shows that bites are predominantly occurring in peri-urban areas where roaming dog populations are high. We must ensure that surveillance for animal bites is tightly integrated with our One Health reporting to veterinary authorities. A single failure to provide PEP to a rabid dog bite victim will invariably result in an agonizing and preventable death. Monitoring these bite trends is essential for forecasting national vaccine requirements and preventing human rabies cases.

    The Ministry of Health is collaborating with the Department of Animal Health to implement mass dog vaccination campaigns in the identified bite hotspots. We urge all district hospitals to report any stockouts of anti-rabies vaccine immediately to the central medical stores. Public education must focus on “Wash, Flush, and Vaccinate” – the critical immediate steps to take after an animal bite occurs. HSAs are encouraged to conduct community sensitization on the dangers of stray dogs and the importance of vaccinating domestic pets. We are also advocating for the improved availability of Rabies Immunoglobulin (RIG) for high-risk Category III exposures in central hospitals. Every bite victim should be followed up to ensure they complete the full multi-dose vaccination schedule required for protection. The zero-death status this week is encouraging, but it requires a perfectly functioning supply chain to be maintained long-term. We will continue to track the “Bite-to-PEP” interval as a key quality indicator for our rabies response program. Elimination of human rabies is possible only through 100% PEP coverage and aggressive animal-level control measures. Let us remain vigilant in protecting our communities from this ancient and deadly viral threat.

    Cholera Status (Suspected vs Confirmed)

    Bulletin Analysis

    Malawi reported seventy-five (75) suspected cholera cases and fourteen (14) laboratory-confirmed cases in week 13, with no deaths recorded. The reporting of 14 confirmed cases in a single week indicates that the cholera situation is entering a more active and dangerous phase. While it is positive that zero deaths occurred, the presence of confirmed cases in multiple districts suggests a widespread environmental risk. Each confirmed case represents a failure in the sanitation barrier and a direct threat to the surrounding community’s health. We are currently focusing our response on the districts of Lilongwe, Blantyre, and Mangochi, which have reported the most recent confirmed activity. The zero-fatality rate this week is a testament to the early seeking of care by patients and effective management by our healthcare teams. However, the high number of suspected cases means that our cholera treatment centers (CTCs) must remain in a state of high readiness. We cannot afford any complacency given the rapid-fire nature of cholera transmission in densely populated areas.

    Aggressive contact tracing and “ring” decontamination of households are being prioritized for all 14 confirmed cases reported this week. We are also distributing chlorine and soap to the families and neighbors of the affected individuals to break the chain of transmission. Our laboratory system is working to perform genomic sequencing on these isolates to understand the lineage and potential origin of the current strain. It is critical that all districts intensify their surveillance for any “sudden onset of watery diarrhoea” and report such events immediately. We are collaborating with WASH partners to ensure that emergency water trucking and borehole repairs are prioritized in the identified hotspots. Public health education campaigns are being scaled up to remind citizens of the importance of using safe water and practicing good hygiene. We are also monitoring the availability of oral rehydration salts and intravenous fluids at the facility level to prevent any supply stockouts. A unified, cross-sectoral response is the only way to contain this current wave of cholera and prevent it from escalating into a national crisis. We will provide daily updates to the affected districts to ensure that local response strategies are data-driven and timely.

    III. Critical Alerts & Mortality

    Maternal Deaths (N=2)

    Bulletin Analysis

    Two (2) maternal deaths were reported in week 13, reminding us of the urgent need to strengthen our emergency obstetric care services. Every maternal death in Malawi is treated as a sentinel event that requires a formal “Maternal Death Surveillance and Response” (MDSR) audit. These deaths are not just statistics; they represent a significant loss of life that has profound effects on families and entire communities. We must investigate whether these deaths were associated with the “Three Delays”: delay in seeking care, reaching a facility, or receiving treatment. Our national goal remains the elimination of all preventable maternal deaths through improved quality of care at the point of delivery. The reporting of these cases through the IDSR system allows for rapid national-level visibility and accountability for reproductive health outcomes. We must ensure that every woman in Malawi has access to skilled birth attendance and emergency services when complications arise. Monitoring these trends helps us identify districts that may be struggling with staffing or equipment shortages in their maternity wings.

    The MDSR committees in the affected districts must complete their investigations and submit their findings to the national secretariat within 72 hours. These audits should focus on identifying systemic gaps, such as lack of blood for transfusion or delays in the referral process between facilities. We are advocating for the implementation of the recommendations arising from these audits to prevent similar tragedies in the future. It is essential that we also look at the quality of antenatal care provided to these women during their pregnancies to identify missed opportunities for intervention. We are working with partners to provide additional training on basic and comprehensive emergency obstetric and newborn care (BEmONC/CEmONC). Community awareness programs should emphasize the importance of early facility-based delivery for all pregnant women, regardless of their perceived risk. We will continue to track maternal mortality with the highest level of priority to ensure that our health system is responsive to the needs of mothers. Every death is a call to action for all stakeholders in the health sector to work harder toward our national targets. We remain committed to achieving the Sustainable Development Goal targets for maternal health through data-driven and evidence-based interventions.

    SARI Mortality (Week 13)

    Bulletin Analysis

    Severe Acute Respiratory Infection (SARI) surveillance reported 212 cases and six (6) deaths in week 13, marking a significant spike in respiratory mortality. This increase in deaths is a major public health concern and may indicate the circulation of more virulent respiratory pathogens or late presentation by patients. We are urging all sentinel sites to increase the collection of swabs for influenza and COVID-19 testing to identify the causative agents. The six deaths reported this week should be audited to understand the clinical course of the illness and the quality of supportive care provided. SARI often affects the very young and the elderly, making them the primary focus of our clinical and preventive efforts. We must ensure that health workers are proficient in the use of oxygen therapy and are following the latest management protocols for severe pneumonia. The high number of cases places an additional burden on our hospital wards and requires careful management of bed capacity. Protecting the population from respiratory threats remains a key component of our national health security strategy during this season.

    Public health messaging should be reinforced to promote hand hygiene, respiratory etiquette, and the use of masks in crowded healthcare settings. We are monitoring for any unusual clusters of respiratory illness in schools, prisons, or other congregate living situations that might indicate an outbreak. District surveillance teams should conduct active case searches in the communities where these deaths occurred to identify any additional undiagnosed cases. We are also working with laboratory partners to ensure that our genomic surveillance is robust enough to detect any new viral variants. It is important to ensure that all frontline health workers have access to personal protective equipment (PPE) to prevent nosocomial transmission of respiratory pathogens. We are advocating for the early referral of SARI patients from primary health centers to district hospitals where specialized care is available. Collaborative research is needed to better understand the seasonal drivers of respiratory infections in the various ecological zones of Malawi. We will continue to provide weekly updates on SARI trends to help facilities prepare for any further increases in morbidity or mortality. Vigilance in monitoring these infections is essential for our national pandemic preparedness and response efforts. Let us work together to contain the spread of these infections and prevent further loss of life in our communities.

    Neonatal Tetanus

    Bulletin Analysis

    Neonatal Tetanus (NNT) surveillance recorded zero (0) cases in week 13, a significant achievement that reflects our high national coverage of Tetanus Toxoid (TT) vaccination. NNT is a painful and highly fatal disease that occurs when Clostridium tetani spores contaminate the umbilical cord during unhygienic deliveries. The absence of cases is a direct result of our successful maternal immunization programs and the promotion of “Clean Birth” practices across the country. We must remain vigilant, however, as even a single case of NNT is considered a major public health failure and an indicator of poor maternal health services. Every suspected case must be investigated immediately to identify the geographical and socioeconomic barriers to safe delivery in that specific community. Our goal is to maintain the “Maternal and Neonatal Tetanus Elimination” (MNTE) status as defined by international health standards. Consistent reporting of zero cases is a testament to the hard work of our midwives and community health assistants in promoting facility-based deliveries. Monitoring these trends allows us to identify any emerging pockets of low vaccination coverage before they result in a clinical case.

    We are continuing to prioritize the vaccination of all pregnant women during their antenatal care (ANC) visits to ensure passive immunity for their newborns. It is also essential to educate traditional birth attendants on the dangers of using unsterilized tools for cord cutting in communities where facility access is limited. HSAs are encouraged to perform active case searching for any infant deaths occurring within the first 28 days of life to ensure no NNT cases are missed. We are providing additional training to clinicians on the clinical diagnosis of NNT, which is characterized by the sudden onset of muscle spasms and “lockjaw.” Integrated surveillance for NNT is linked with our wider efforts to reduce overall neonatal mortality and improve child survival rates in Malawi. The reporting of zero cases this week should not lead to any reduction in our immunization outreach or hygiene promotion efforts. We will continue to advocate for the universal provision of “Mama Kits” that include sterile cord-care materials for every expectant mother. Our commitment to a tetanus-free future for every Malawian child remains a cornerstone of our national reproductive and child health strategy. Ongoing surveillance is the only way to prove that our elimination status is being successfully sustained year after year. Let us work together to ensure that no child in Malawi ever has to suffer from this preventable and agonizing disease.

    IV. Vaccine Preventable & Special Events

    Mpox Status (Week 13)

    Bulletin Analysis

    Malawi maintained a status of zero (0) new confirmed Mpox cases and zero (0) alerts during epidemiological week 13. This continued absence of cases is a highly positive sign, but it must be met with sustained vigilance rather than complacency. The risk of Mpox introduction remains significant given the ongoing transmission in the region and the high volume of cross-border movement. Our border surveillance teams must continue to screen travelers for symptoms and maintain a high index of suspicion for unusual rashes. Mpox remains a disease of international concern, and Malawi’s reporting contributes to the broader global understanding of the virus’s spread. We are continuing to provide mentorship on case definition and sample management to healthcare workers in all district hospitals. Public awareness campaigns should be sustained to ensure that the community knows to report any suspicious lesions or fevers immediately. Early detection remains our primary strategy for preventing a localized outbreak from becoming a national epidemic in 2026.

    Laboratory capacity for Mpox molecular testing is being regularly verified at the national reference lab to ensure rapid turnaround times for any alerts. We are also collaborating with international health partners to share data and refine our national preparedness and response plans for viral hemorrhagic fevers. It is essential for clinicians to differentiate Mpox from other common rash-illnesses like chickenpox or measles through thorough clinical examination. We are also working to strengthen community-based surveillance to identify any cases that might be deterred from facilities due to stigma. The current period of zero cases allows us to further refine our clinical guidelines and stockpile necessary infection prevention and control (IPC) supplies. We are reviewing our genomic surveillance capabilities to ensure we can identify the specific clade of the virus if an introduction occurs. Every alert that is investigated and ruled out is a sign that our surveillance system is functioning with high sensitivity and accuracy. We encourage all districts to continue their active case searching during routine facility and community visits to ensure no case is missed. Protecting Malawi from Mpox requires a unified effort from all health sectors and the active participation of the general public.

    AFP (Polio) & Measles

    Bulletin Analysis

    Acute Flaccid Paralysis (AFP) surveillance reported three (3) new cases in week 13, all of which are currently undergoing laboratory verification to rule out Polio. These cases were identified in diverse geographical areas, showing that our detection system is capable of picking up rare clinical events across the country. AFP surveillance is a global requirement for maintaining our polio-free status, and Malawi is committed to meeting all international performance standards. Each of these three cases must have two “adequate” stool samples collected 24 hours apart within 14 days of paralysis onset. We are also tracking thirty-three (33) suspected measles cases this week, which represents a concerning increase in potential vaccine-preventable disease activity. Measles is one of the most contagious viral diseases and can rapidly spread through communities with low immunization coverage. Even a single confirmed measles case is considered an outbreak in Malawi and requires an immediate and aggressive vaccination response. We must ensure that our routine immunization programs are reaching the most remote and marginalized populations to prevent these outbreaks.

    Health workers are reminded that any child with fever and a maculopapular rash must be investigated for measles, with blood and swab samples collected for testing. We are urging all districts to review their “Immunization Recovery Plans” to identify and vaccinate children who have missed their scheduled doses. The presence of 33 suspected cases indicates that there may be significant immunity gaps that need to be addressed through supplemental immunization activities. Community health surveillance assistants (HSAs) should intensify their home visits to check the vaccination status of all children under the age of five. We are also monitoring for any signs of “Polio-compatible” cases that might indicate low-level circulation of the virus in areas with poor sanitation. Laboratory results for the current AFP cases will be communicated to the districts as soon as they are finalized by the regional reference lab. Maintaining a high level of vigilance for these diseases is essential for the long-term health and development of Malawi’s children. We must not allow the progress made in global eradication efforts to be reversed by local surveillance or immunization gaps. Collaborative efforts between the EPI program and the IDSR secretariat are being strengthened to ensure an integrated approach to these threats.

    Typhoid Fever Status

    Bulletin Analysis

    Typhoid fever surveillance recorded sixty-nine (69) cases in week 13, showing a continued upward trend that requires urgent attention from public health authorities. This volume of cases indicates that enteric transmission of Salmonella Typhi is becoming more widespread in several urban and peri-urban centers. Typhoid is a significant cause of febrile illness in Malawi and can often be misdiagnosed as malaria without proper laboratory testing. We are advocating for the wider use of blood culture as the gold standard for diagnosing typhoid fever in all district hospitals. The current trend suggests that there are significant issues with water safety and food hygiene that are facilitating the spread of the bacteria. Each case of typhoid represents a potential failure in the community’s water and sanitation barriers that must be investigated and addressed. We are particularly concerned about the potential for multi-drug resistant typhoid strains to emerge if antibiotic stewardship is not strictly practiced. The surveillance data this week highlights the need for a multi-sectoral response to improve safe water access in the most affected areas.

    Environmental health investigations are being prioritized for the clusters of typhoid cases identified in this week’s surveillance report. We urge the districts to work closely with local government and water boards to ensure that water sources are properly chlorinated and protected from contamination. Public health messaging should focus on the importance of “boil and use” practices for all drinking water in areas where typhoid is currently circulating. We are also monitoring the impact of the Typhoid Conjugate Vaccine (TCV) program and identifying areas where additional vaccination coverage may be needed. Schools and food markets should be the focus of intensive hygiene promotion activities to reduce the risk of large-scale community transmission. It is essential that clinicians follow the national treatment guidelines and complete the full course of antibiotics to prevent the development of chronic carriers. We will continue to map the geographical distribution of typhoid cases to help target our preventive interventions and resource allocation. Long-term solutions for typhoid must include significant investments in permanent safe water and sewerage infrastructure across Malawi. Let us maintain a high index of suspicion and respond aggressively to every cluster of febrile illness that could be typhoid fever. Strengthening our enteric disease surveillance is a key priority for the national public health institute this year.

    V. Summary of Recommendations

    1. EBS Verification Improvement

    Districts must clear the backlog of 10 unverified EBS signals. All community alerts require field investigation and documentation in OHSP within 24 hours.

    2. Outbreak Response

    Aggressive decontamination and contact tracing must be sustained for all confirmed cholera and typhoid cases. Pre-positioning of kits in high-risk zones is mandatory.

    3. Clinical Excellence

    Complete clinical audits for all 10 malaria deaths and 2 maternal deaths within 72 hours. Focus on reducing clinical delays and improving severe case management.

    I. Performance & Surveillance

    District Reporting Completeness

    Bulletin Analysis

    National completeness for epidemiological week 10 was recorded at a strong 96.0%, reflecting consistent engagement across all districts. This high level of reporting ensures that our public health visibility remains sharp during the transition between weather seasons. When nearly all facilities submit data, we can trust that the national disease burden is being captured with high fidelity. Every single percentage point contributes to a more accurate risk assessment for the Ministry of Health and its stakeholders. The One Health Surveillance Platform has clearly become the backbone of our data management culture nationwide. We commend the district coordinators who have pushed their teams to maintain this standard throughout the current quarter. Sustained completeness is the first step toward effective disease control and equitable resource allocation for all Malawians.

    Despite this success, the 4.0% gap represents facilities that are currently operating in a data blind spot. It is essential that district health management teams identify these specific non-reporting units to address technical or staffing bottlenecks. If a facility consistently fails to report, it may hide localized outbreaks that could easily spread to neighboring communities. Our goal remains a 100% completeness rate to ensure that no single citizen is left out of the surveillance safety net. Zonal epidemiology officers should provide targeted mentorship to facilities struggling with digital data entry procedures. We are also looking into enhancing the mobile reporting features of the OHSP to make submission easier for remote clinics. Future bulletins will track the progress of these specific “laggard” facilities to ensure they are brought back into the fold. Collective accountability is what drives the integrity of our national health information system.

    Timeliness Performance

    Bulletin Analysis

    Timeliness in week 10 also stood at 96.0%, mirroring the completeness rate and indicating a highly responsive surveillance workforce. Reporting on time is critical because it allows the national secretariat to analyze data while the epidemiological events are still fresh. A delay of even 24 hours can hinder the rapid deployment of response teams to a potential cholera or measles cluster. This week’s performance shows that the vast majority of our focal persons treat the Monday deadline with professional urgency. It reflects a maturing system where data is viewed as a vital tool for clinical and public health action. We recognize that maintaining such timeliness requires significant effort in areas with poor internet connectivity or power supply. The resilience shown by our data clerks under these conditions is a major asset to the nation. Timely data translates directly into saved lives through faster decision-making and resource mobilization.

    However, we must address the remaining 4.0% of reports that arrived after the established national deadline. Late reports often stall the generation of this very bulletin and delay the feedback loop to the districts. District Health Officers should review their internal validation workflows to ensure that data does not sit idle before submission. We have observed that timeliness often dips during periods of high clinical workload, which is precisely when data is most needed. It is important to cross-train multiple staff members at the facility level to handle reporting duties during staff absences. PHIM will continue to publish the list of districts meeting the timeliness target to encourage healthy competition and shared learning. We are also planning to implement automated reminders within the OHSP to help facility staff keep track of deadlines. Ensuring 100% timeliness will solidify Malawi’s position as a regional leader in real-time epidemiological surveillance. Let us all work together to ensure that no report arrives too late to make a difference.

    EBS Signal Distribution

    Bulletin Analysis

    During week 10, the Event-Based Surveillance (EBS) system captured a total of fourteen (14) distinct signals across various districts. While this is a decrease from the nineteen signals reported in week 2, it indicates a functioning community-level alert system. EBS is specifically designed to catch “unusual” events that might not fit into standard diagnostic categories in the early stages. Each signal represents a proactive observation by a community health worker or a vigilant community member. The distribution of these signals across regions suggests that our training on signal detection is yielding results. Every signal must be treated as a potential public health threat until a formal risk assessment is completed. This sensitive “radar” is what allows us to identify outbreaks before they escalate into full-blown national crises. We value the alertness of the community health surveillance assistants who are our eyes and ears on the ground.

    The next critical step for these 14 signals is immediate verification and risk assessment by District Rapid Response Teams. A signal only becomes an actionable public health event once it has been investigated and validated in the field. We have noticed that while signal detection is improving, the documentation of the follow-up investigation remains a weakness. It is vital that DRRTs record every investigative step and outcome in the One Health Surveillance Platform. Without this documentation, we cannot assess the effectiveness of our response or learn from the signals that were false alarms. We urge district coordinators to prioritize the “closing the loop” on every alert generated this week. Strengthening the linkage between signal detection and rapid field response is a top priority for our 2026 surveillance strategy. Training on “Signal-to-Action” workflows will be rolled out in the coming months to enhance this capability. Our community’s safety depends on our ability to not just listen to signals, but to act upon them decisively.

    II. Disease Morbidity

    Malaria Trends (Week 10)

    Bulletin Analysis

    Malaria remains the highest cause of morbidity in Malawi, with 33,365 cases and 8 associated deaths reported in week 10. This case volume indicates that transmission remains high, particularly in districts experiencing heavy rainfall and increased vector activity. The eight deaths reported this week are a tragic reminder that severe malaria is still a major killer in our communities. Each of these deaths should be subjected to a clinical audit to identify any delays in care-seeking or treatment. We are monitoring these trends closely to ensure that our supply chain for anti-malarials remains robust and uninterrupted. High-burden districts must prioritize the distribution of insecticide-treated nets and promote their consistent use among the population. Surveillance data shows that certain southern districts are reporting higher-than-expected case densities this month. Our response must be data-driven, focusing resources on the specific hotspots where transmission is most intense right now.

    Preventing malaria deaths requires a combination of community awareness and high-quality clinical management at the facility level. Parents must be encouraged to bring children with fever to a health facility within 24 hours for testing. Early diagnosis and treatment with effective ACTs are the most reliable ways to prevent progression to severe disease. Health facility managers should ensure that their staff are fully trained in the management of severe malaria complications. We are also advocating for improved environmental management to reduce mosquito breeding sites around households and public areas. The national malaria control program is reviewing this week’s data to plan for upcoming indoor residual spraying campaigns. It is essential that we maintain high coverage of all prevention interventions to see a significant drop in these numbers. Every malaria death is a public health failure that we must work tirelessly to eliminate in the near future. Collaborative efforts between the government, partners, and the community are essential for achieving a malaria-free Malawi.

    Bloody Diarrhoea

    Bulletin Analysis

    A total of 775 cases of bloody diarrhoea were reported in week 10, representing a significant enteric disease burden. This condition is often a marker for Shigellosis or other bacterial pathogens that thrive in areas with poor sanitation. During the rainy season, the risk of water source contamination increases, leading to spikes in diarrhoeal diseases. We must ensure that all health facilities are collecting stool samples for culture and sensitivity testing from these patients. Understanding the antibiotic resistance patterns of circulating pathogens is crucial for updating our treatment guidelines. Every case of bloody diarrhoea should be managed with the same level of urgency as a potential cholera case. Community health workers should intensify education on handwashing with soap and the use of treated drinking water. The current case count suggests that our water and sanitation infrastructure needs urgent attention in several districts. We cannot afford to overlook these “silent” enteric threats while focusing on more visible outbreaks.

    The geographical distribution of these 775 cases points to specific clusters that require immediate environmental health investigations. District environmental health officers should inspect water points in the most affected traditional authorities to identify sources of contamination. We are also monitoring for any signs of antibiotic treatment failure, which could indicate the emergence of resistant strains. Public health messaging must be reinforced to ensure that families know how to properly treat water at the household level. Schools and markets should be targeted for hygiene promotion to prevent the rapid spread of infection in crowded settings. We are collaborating with the Ministry of Water to prioritize the repair of broken boreholes in the high-incidence zones identified this week. Surveillance focal persons are reminded to report any sudden increase in cases within a single community as a priority alert. By addressing the root causes of bloody diarrhoea, we also strengthen our defense against other waterborne diseases. Let us maintain a high index of suspicion and respond aggressively to every cluster of enteric illness. Safe water and proper sanitation are non-negotiable rights for every citizen in our country.

    Cholera Status (Suspected vs Confirmed)

    Bulletin Analysis

    In week 10, Malawi reported sixty-seven (67) suspected cholera cases and four (4) laboratory-confirmed cases, with no deaths. While the number of confirmed cases is low, the presence of nearly seventy suspected cases indicates ongoing transmission risk. It is encouraging that zero deaths were reported, showing that our cholera treatment centers are providing effective rehydration. However, we must remain vigilant as cholera can explode into a massive outbreak within a very short timeframe. Each suspected case represents a potential chain of transmission that must be broken through aggressive contact tracing. Confirmed cases this week were primarily located in districts with known challenges in safe water access. We are pre-positioning cholera kits and supplies in these areas to ensure readiness for any escalation. The surveillance system is the primary tool for mapping these cases and targeting our preventive interventions. We must not allow “cholera fatigue” to diminish our response efforts during this critical rainy season.

    Aggressive decontamination of households and public spaces where cases have been identified is currently underway in the affected districts. We are also working with local leaders to ensure that community members understand the importance of seeking help early. Early treatment with oral rehydration salts can be life-saving and prevents the development of severe, lethal dehydration. Our laboratory capacity for cholera testing is being monitored to ensure that results are returned to the field within 24 hours. We are also tracking the availability of chlorine for water treatment at both the facility and community levels. Collaborative meetings with partners are held daily at PHIM to review the latest data and adjust our national response plan. It is essential that every district remains in a high state of alert, even those that have not yet reported a case. Cholera is a cross-border threat that requires a unified and well-coordinated response from all sectors of society. We will continue to provide transparent and timely updates on the cholera situation through these weekly bulletins. Together, we can prevent a repeat of the massive outbreaks seen in previous years through early action.

    III. Critical Alerts & Mortality

    Maternal Deaths (N=2)

    Bulletin Analysis

    The reporting of two (2) maternal deaths in week 10 is a somber reminder of the challenges in our reproductive health system. Every maternal death is considered a sentinel event that triggers a mandatory national-level review and local clinical audit. These deaths represent not just a statistic, but the loss of a mother and a devastating impact on a family. We must investigate whether these deaths were due to delays in seeking care, reaching a facility, or receiving treatment. Maternal mortality is a key indicator of the overall quality and accessibility of our healthcare system. The Ministry of Health remains committed to achieving the goal of zero preventable maternal deaths in Malawi. We are working to strengthen the capacity of our maternity wards and ensure they are adequately staffed and supplied. It is vital that we learn from every tragedy to prevent future occurrences in our health facilities. Monitoring maternal mortality trends helps us identify districts that require additional support and clinical mentorship.

    Clinical audits for these two deaths must be completed within the next seven days to identify the root causes. These audits are essential for identifying systemic gaps such as lack of blood for transfusion or shortage of essential medicines. We must also look at the quality of antenatal care these women received prior to their delivery. Community awareness programs should emphasize the importance of early booking and delivery in a health facility under skilled supervision. We are advocating for improved transport systems to ensure pregnant women in remote areas can reach emergency care in time. Zonal supervisors should follow up with the affected districts to ensure that the audit recommendations are being implemented. Our goal is to create a culture of safety where every pregnancy is monitored and every delivery is safe. We will continue to track maternal mortality with the highest priority in our surveillance reports to ensure accountability. Strengthening the linkage between community surveillance and facility-based care is a key strategy for reducing these deaths. Every mother’s life is precious, and we must do everything in our power to protect them during childbirth.

    SARI Mortality (Week 10)

    Bulletin Analysis

    Week 10 saw 241 cases of Severe Acute Respiratory Infection (SARI) and three (3) associated deaths reported nationwide. This represents a significant increase in respiratory morbidity compared to the very low numbers reported in week 9. Such a jump in cases often follows changes in weather patterns or the introduction of new viral strains into the community. We must ensure that our sentinel sites are collecting swabs for influenza and COVID-19 testing to identify the causative agents. The three deaths this week underscore the potential severity of respiratory infections in vulnerable populations. Healthcare workers are reminded to practice strict infection prevention and control (IPC) measures when managing SARI patients. Early identification of severe cases and prompt initiation of supportive care, including oxygen therapy, are critical for survival. We are monitoring the availability of respiratory medicines and supplies across all central and district hospitals. Protecting our population from respiratory threats requires a vigilant and well-equipped healthcare workforce at all levels.

    Public health messaging should continue to promote hand hygiene and respiratory etiquette to reduce the spread of viruses. We are particularly concerned about the risk of respiratory outbreaks in crowded settings such as schools, prisons, and displacement camps. District surveillance teams should investigate any sudden clusters of fever and cough to rule out potential outbreaks. The current trend suggests that we may be entering a period of increased respiratory virus circulation. We are working with our laboratory partners to enhance the turnaround time for respiratory viral panels. Information on the specific viruses circulating will be shared with clinicians to guide their patient management strategies. It is also important to ensure that high-risk groups, such as the elderly and those with comorbidities, are monitored closely. We will continue to provide weekly updates on SARI trends to help facilities prepare for any further increase in patient volume. Vigilance in monitoring respiratory infections is a key component of our national pandemic preparedness and response strategy. Let us work together to contain the spread of these infections and prevent further mortality in our communities.

    AEFI Surveillance (74 cases)

    Bulletin Analysis

    A total of seventy-four (74) cases of Adverse Events Following Immunization (AEFI) were reported in week 10. The reporting of these events is a sign of a robust and transparent vaccine safety monitoring system. Most of these cases were minor and expected reactions, such as fever or pain at the injection site, which resolved quickly. It is essential that health workers continue to report all AEFI, regardless of their perceived severity or relationship to the vaccine. This data is reviewed by a national committee to ensure that the vaccines used in our programs remain safe for the public. High reporting rates reflect the vigilance of our immunization teams and the trust of the community in our surveillance. We have not identified any serious or life-threatening AEFI patterns during this reporting period, which is reassuring for our health programs. Maintaining public confidence in vaccines is vital for achieving high immunization coverage and protecting our children from preventable diseases. We will continue to monitor these reports with the highest level of scientific scrutiny and transparency.

    Training for health workers on AEFI detection and management is being reinforced during routine supervision visits. It is important to distinguish between events caused by the vaccine and coincidental events that happen around the time of vaccination. Clear communication with parents and caregivers about potential side effects helps to manage expectations and reduce vaccine hesitancy. We are also monitoring the quality of vaccine storage and handling, as improper cold chain management can sometimes lead to localized AEFI clusters. The national immunization program is using this data to continuously improve the safety and quality of its services. Any serious AEFI would trigger an immediate field investigation and a formal causality assessment by the national expert committee. We encourage the public to report any unusual health events following vaccination to their nearest health facility or via the health hotline. Our commitment to vaccine safety is absolute, and we will not compromise on the health of our citizens. Transparency in reporting and addressing these events is the foundation of a successful and sustainable immunization program. We appreciate the hard work of all the frontline workers who ensure that every dose is safe and every event is recorded.

    IV. Vaccine Preventable & Special Events

    Mpox Status (Week 10)

    Bulletin Analysis

    Malawi reported zero (0) new confirmed Mpox cases and zero (0) Mpox alerts during epidemiological week 10. This continued status of zero cases is an excellent indicator that our current containment and awareness strategies are effective. However, we must not become complacent, as the risk of cross-border transmission from neighboring countries remains significant. Our border screening teams and surveillance focal persons in border districts must remain in a state of high alert. Mpox is a disease of international concern, and we have a global responsibility to maintain a sensitive detection system. We are continuing to provide training on Mpox case identification and sample collection to healthcare workers in high-risk areas. Public awareness campaigns are ongoing to ensure that the population knows the signs and symptoms of the disease. Early detection is our best tool for preventing a widespread outbreak of this viral pathogen in our communities. We are proud of the vigilance shown by our health workforce in maintaining this “zero case” status for another week.

    Laboratory readiness for Mpox testing is being maintained at the national reference lab to ensure we can respond to any new alert. We are also collaborating with regional partners to monitor the spread of the virus across the continent and adjust our risk assessments. It is important for clinicians to maintain a high index of suspicion for any patient with an unexplained rash or fever. We are also working to strengthen our community-based surveillance to identify any “hidden” cases that might not reach health facilities. The current period of zero cases provides a window of opportunity to further strengthen our clinical and laboratory systems. We are reviewing our national Mpox response plan to incorporate lessons learned from the global outbreak and regional trends. Every alert, even if eventually discarded, is a sign that our surveillance system is “awake” and functioning as intended. We encourage the public to report any suspicious illness through the official channels without fear of stigma. Protecting Malawi from Mpox requires a collective effort and a commitment to transparency and rapid response. We will continue to provide weekly status updates to keep all stakeholders informed of our national situation.

    AFP (Polio) & Measles

    Bulletin Analysis

    Acute Flaccid Paralysis (AFP) surveillance remains a top priority, with three (3) new cases reported and investigated in week 10. These cases are currently undergoing laboratory testing to rule out the presence of poliovirus and ensure our polio-free status. AFP surveillance is a key requirement for global polio eradication, and Malawi must meet strict performance targets for case detection. Each case requires the collection of two stool samples within 14 days of the onset of paralysis to be considered “adequate.” We are also closely monitoring for any suspected measles cases, as even a single case can indicate a gap in population immunity. Measles is highly contagious and can lead to severe complications or death in unvaccinated children. We are urging all districts to maintain high routine immunization coverage to prevent the recurrence of measles outbreaks. Surveillance focal persons should conduct active case searches for AFP and measles during their routine facility visits. Ensuring that every child is protected from these preventable diseases is a core mission of our public health system.

    The success of our AFP surveillance depends on the awareness of both healthcare workers and the community about the signs of paralysis. We are providing regular updates and mentorship to facility staff on how to identify and report AFP cases promptly. It is also important to ensure that the cold chain for stool sample transport is strictly maintained until they reach the laboratory. For measles, we are conducting a review of our vaccination data in the areas where suspected cases were reported this week. Any child found to be missing their scheduled doses should be immunized immediately to close the immunity gap. We are also planning for upcoming supplemental immunization activities to boost population immunity in high-risk districts. Collaborating with community leaders is essential for ensuring that all children are reached during vaccination campaigns. We will continue to share the laboratory results for the AFP cases as soon as they become available from the reference lab. Maintaining a high level of vigilance for these vaccine-preventable diseases is essential for the long-term health of our nation’s children. Let us work together to ensure that Polio and Measles remain diseases of the past in Malawi.

    Typhoid Fever Status

    Bulletin Analysis

    Week 10 saw a sharp increase in Typhoid fever cases, with fifty-four (54) cases reported compared to just eighteen in week 9. This jump in cases is a significant epidemiological signal that requires an immediate and coordinated response at the district level. Typhoid fever is primarily spread through contaminated food and water, often flourishing in areas with inadequate sanitation infrastructure. The current increase during the rainy season suggests that water sources may have been compromised by surface runoff. We are urging all affected districts to conduct immediate environmental health investigations to identify the source of the infection. Laboratory confirmation through blood culture is essential for distinguishing typhoid from other febrile illnesses like malaria. We must also ensure that patients are being treated with the correct antibiotics according to our national guidelines. Typhoid can lead to severe complications, including intestinal perforation, if it is not diagnosed and treated promptly. Our surveillance system is working at full capacity to map these cases and identify any emerging hotspots.

    The prevention of typhoid fever relies heavily on improving access to safe water and promoting rigorous hygiene practices in our communities. We are advocating for the boiling or treatment of all drinking water in the districts that are currently reporting increased cases. Public health teams should also target food vendors and markets for hygiene education and inspection to prevent foodborne transmission. We are also monitoring the impact of the Typhoid Conjugate Vaccine (TCV) in the populations where it has been rolled out. Vaccination remains a key long-term strategy for reducing the national burden of typhoid and protecting our children. We are collaborating with the Ministry of Water to prioritize the repair and maintenance of water systems in high-risk areas. It is essential that we address the root causes of this disease to prevent it from becoming a persistent public health problem. Surveillance focal persons should continue to report every suspected case of typhoid with the highest priority to enable rapid response. We will provide further updates on the typhoid situation as more data and laboratory results become available. Working together, we can contain this current increase and protect the health and well-being of our citizens through effective prevention.

    V. Summary of Recommendations

    1. Data Quality & Reporting

    Districts should maintain 100% completeness and timeliness. Non-reporting facilities must be identified and supported by District Health Management Teams to close the 4% gap.

    2. Outbreak Response

    Aggressive contact tracing and environmental decontamination must continue in cholera and typhoid hotspots. Ensure pre-positioning of kits in all high-risk districts.

    3. Clinical Excellence

    Conduct mandatory audits for all maternal and malaria deaths within 7 days. Focus on reducing delays in care-seeking and improving facility-level management of severe cases.

    I. Performance & Surveillance

    District Reporting Completeness

    Bulletin Analysis

    During Epidemiological Week 9, the national completeness of reporting on the One Health Surveillance Platform (OHSP) was recorded at 95.3%. This represents a slight decrease compared to the high-performance levels observed in earlier weeks of the year. Despite the dip, the national average remains well above the 80% threshold required for effective public health decision-making. It is imperative that district surveillance teams identify specific facilities that failed to report to ensure no critical health events are missed. Consistent reporting across all districts allows the Ministry to maintain a comprehensive understanding of the country’s disease landscape.

    Moving forward, the focus must remain on supporting health facilities that have shown a downward trend in submission rates. The surveillance secretariat will continue to monitor non-reporting units to determine if technical barriers or staffing shortages are contributing to the decline. Surveillance officers at the district level should prioritize providing feedback to facility focal persons to emphasize the value of every single report. Improving completeness to at least 98% is a key objective for the second quarter of 2026. Maintaining high data quality and completeness is essential for triggering timely responses to potential health emergencies across the nation.

    Timeliness Performance

    Bulletin Analysis

    The national timeliness of reporting for Week 9 was 94.7%, indicating a robust adherence to the weekly reporting deadlines. This high level of timeliness is crucial for the early detection and containment of disease outbreaks before they escalate into national crises. The surveillance system depends on receiving data within the stipulated timeframe to allow for real-time analysis and action. When reports are submitted on time, rapid response teams can be deployed more effectively to hotspots of infection. The current performance reflects the dedication of health facility focal persons and district coordinators in prioritizing surveillance tasks.

    However, we continue to observe a gap between the best-performing districts and those that frequently struggle with meeting the Monday noon deadline. Some districts and central hospitals have been specifically flagged for needing improvement in their reporting speed this week. Addressing issues such as internet connectivity and data entry backlogs at the facility level will be necessary to bridge this performance gap. The national goal remains to achieve 100% timeliness to ensure the surveillance system operates at its maximum potential. Continued mentorship and technical support will be provided to the lagging reporting units to ensure they meet national standards consistently.

    EBS Signal Distribution

    Bulletin Analysis

    Event-Based Surveillance (EBS) detected twenty-six (26) signals during Week 9, highlighting the sensitivity of our community and facility-level alert systems. These signals are vital as they often capture unusual health events that routine indicator-based surveillance might miss in the early stages. The diverse nature of these alerts suggests that both the general public and health workers are maintaining a high level of vigilance. Each signal represents a potential threat that must be meticulously investigated to determine its public health significance. This proactive detection is a cornerstone of Malawi’s commitment to early warning systems for emerging infectious diseases.

    Once a signal is recorded, the responsibility shifts to the District Rapid Response Teams (DRRTs) to conduct immediate verification and risk assessments. It is essential that all twenty-six signals reported this week are followed up with documented outcomes to close the surveillance loop. Delayed investigations can lead to missed opportunities for containing localized outbreaks at their source. We encourage all districts to ensure their EBS focal persons are adequately resourced to perform these critical field investigations promptly. Strengthening the linkage between signal detection and rapid field response remains a top priority for the Public Health Institute of Malawi in the coming months.

    II. Disease Morbidity

    Malaria Trends (Week 9)

    Bulletin Analysis

    Malaria continues to be the leading cause of morbidity in Malawi, with 21,314 cases and 5 deaths reported in Week 9. Although the number of cases shows a downward trend compared to the peak season, the mortality rate remains a serious concern for public health. Each death signifies a potential failure in early diagnosis or the management of severe malaria at the facility level. It is crucial that clinicians strictly adhere to the national treatment guidelines, including the use of injectable artesunate for severe cases. Health facilities must also ensure they maintain adequate stocks of both rapid diagnostic tests and artemisinin-based combination therapies.

    Prevention efforts, such as the consistent use of insecticide-treated bed nets, must be emphasized during community outreach and routine health education sessions. We are also monitoring districts with unusually high case-fatality rates to determine if there are specific gaps in care-seeking behavior or clinical expertise. Community health workers play a vital role in identifying signs of severe illness and ensuring timely referral to higher levels of care. The National Malaria Control Program will continue to utilize this surveillance data to target resources to the most burdened districts. Reducing the malaria burden requires a sustained multi-sectoral approach involving environmental management and robust clinical services.

    Bloody Diarrhoea

    Bulletin Analysis

    During Week 9, a total of 437 cases of bloody diarrhoea were reported across the country, showing a significant decrease from the previous month’s levels. This reduction is a positive sign, yet the persistent reporting of hundreds of cases weekly indicates ongoing challenges with sanitation and hygiene. Bloody diarrhoea is often associated with Shigellosis, which can spread rapidly in areas with inadequate access to clean water and soap. Health facilities should continue to prioritize laboratory investigation for these cases to identify the specific causative agents. Understanding the local epidemiology of enteric diseases is essential for tailoring effective public health interventions and treatment protocols.

    Districts reporting clusters of bloody diarrhoea must conduct environmental assessments to identify contaminated water sources or poor waste disposal practices. Public health messaging should focus on the “Five Keys to Safer Food” and the importance of handwashing with soap at critical times. We also urge healthcare providers to maintain high clinical suspicion for potential cholera cases among patients presenting with severe diarrhoeal illness. Continued monitoring of these trends will help determine if the current downward trajectory is sustained or if new hotspots are emerging. Strengthening water, sanitation, and hygiene (WASH) infrastructure remains the most effective long-term strategy for preventing these infections.

    Cholera Status (Suspected vs Confirmed)

    Bulletin Analysis

    The cholera situation in Week 9 involved sixty-six (66) suspected cases and three (3) laboratory-confirmed cases, with no deaths reported. While the number of confirmed cases remains low, the presence of sixty-six suspected cases suggests that the risk of transmission is still high in certain communities. It is encouraging that zero deaths were recorded, reflecting effective clinical management and early care-seeking behavior in the affected areas. However, the discovery of any confirmed case proves that the Vibrio cholerae bacterium is actively circulating and poses a threat to public health. Rapid containment of these early cases is necessary to prevent a widespread outbreak during the current rainy season.

    Response activities must focus on intensive contact tracing and the provision of safe water and sanitation in the immediate vicinity of confirmed cases. We recommend that all suspected cases are managed in designated cholera treatment units to prevent cross-infection within regular hospital wards. Health education should be intensified in known hotspots to ensure that the community knows how to prepare and use Oral Rehydration Salts at home. The Ministry of Health and its partners are continuing to distribute water treatment chemicals and hygiene kits to high-risk populations. Vigilant surveillance at the community level is essential for identifying the very first signs of a potential cluster of cases.

    III. Critical Alerts & Mortality

    Maternal Deaths (N=1)

    Bulletin Analysis

    Only one (1) maternal death was reported during Week 9, which represents a notable decline compared to the levels seen earlier in the year. While the reduction in mortality is positive, the goal of the health system remains the total elimination of preventable maternal deaths. Every maternal death is a profound loss and must be investigated thoroughly to understand the contributing clinical and social factors. Maternal mortality remains a key indicator of the quality and accessibility of emergency obstetric and neonatal care services. We must ensure that all pregnant women have access to skilled birth attendants and timely referral systems when complications arise.

    The District Health Management Team is required to conduct a Maternal and Perinatal Death Surveillance and Response (MPDSR) audit for this case. These audits are essential for identifying system failures, such as delays in seeking care, transportation challenges, or gaps in facility-level management. The lessons learned from this specific audit must be translated into actionable improvements for the maternity department and community referral pathways. Continuous training for midwives and clinicians on managing postpartum hemorrhage and eclampsia is a priority for reducing such fatalities. We remain committed to ensuring that no woman dies while giving life due to preventable causes.

    SARI Mortality (Week 9)

    Bulletin Analysis

    Severe Acute Respiratory Infection (SARI) surveillance identified only two (2) cases during Week 9, with no associated deaths reported. This significant drop in SARI morbidity compared to previous weeks may be due to seasonal variations or a temporary decline in circulating respiratory pathogens. However, the low number of reported cases also warrants a review of surveillance sensitivity at the facility level to ensure cases are not being missed. It is vital that healthcare workers continue to screen all patients presenting with fever and cough for potential SARI. Maintaining a high level of vigilance is necessary for the early detection of respiratory viruses with pandemic potential, such as influenza or SARS-CoV-2.

    Sentinel sites should continue to collect samples for laboratory testing to monitor the types of viruses circulating in the population. Accurate viral surveillance helps inform national treatment guidelines and public health strategies for managing respiratory illness. Even with low case numbers, facilities must ensure that oxygen therapy equipment and essential medicines are ready for any sudden influx of patients. We also encourage the public to continue practicing good respiratory hygiene and to seek medical attention if they experience difficulty breathing. The surveillance secretariat will continue to monitor SARI trends closely to detect any unusual increases in respiratory morbidity or mortality.

    AEFI Surveillance (59 cases)

    Bulletin Analysis

    In Week 9, there were fifty-nine (59) reports of Adverse Events Following Immunization (AEFI) submitted through the surveillance system. Most of these events were minor reactions, such as low-grade fever or localized swelling at the injection site, which are expected after vaccination. The consistent reporting of AEFI is a sign of a healthy surveillance system that prioritizes vaccine safety and public confidence. It is important for health workers to reassure parents that these minor reactions are usually self-limiting and indicate that the immune system is responding to the vaccine. Accurate documentation of all AEFI cases allows the national regulatory authorities to monitor the safety profile of all vaccines used in the country.

    Any serious AEFI, such as those requiring hospitalization or resulting in significant disability, must be investigated within 48 hours by the district team. For Week 9, none of the 59 reported cases were classified as serious, which is a reassuring finding for the national immunization program. We continue to encourage health workers to report every event, no matter how minor, to maintain a robust safety database. Transparency in reporting and investigating these events is essential for addressing vaccine hesitancy and ensuring high coverage for life-saving immunizations. The Ministry of Health remains committed to providing the safest possible vaccines to all citizens of Malawi.

    IV. Vaccine Preventable & Special Events

    Mpox Status (Week 9)

    Bulletin Analysis

    For the eighth consecutive week, Malawi has reported zero (0) new confirmed cases of Mpox and zero (0) new alerts during Week 9. This prolonged period without new cases suggests that the public health interventions implemented last year have been effective in halting community transmission. However, the regional situation remains unpredictable, with neighboring countries continuing to report active cases and outbreaks. The risk of cross-border importation remains a significant threat that requires us to maintain high levels of vigilance at all points of entry. We must not allow the current success to lead to complacency in our surveillance and preparedness efforts.

    Screening protocols at international airports and border crossings must continue to be strictly enforced to detect any symptomatic travelers. Healthcare workers should remain trained in the identification, isolation, and management of Mpox suspects to ensure rapid containment if a case is imported. We are also continuing our community awareness campaigns to ensure the public knows the symptoms and where to report if they suspect an infection. Maintaining laboratory readiness to test samples quickly is also a key priority for the national reference lab. Our commitment to a “Zero Mpox” status requires constant monitoring and a ready-to-act response framework.

    AFP (Polio) & Measles

    Bulletin Analysis

    Surveillance for Acute Flaccid Paralysis (AFP) remained active in Week 9, which is critical for maintaining Malawi’s status as a Polio-free nation. AFP is the primary clinical indicator used to monitor for the potential re-introduction of the Poliovirus. Along with AFP, we are also monitoring for any clusters of fever and maculopapular rash that could indicate a Measles outbreak. Measles is highly contagious and can cause significant morbidity and mortality in unvaccinated or under-vaccinated children. High-quality surveillance for these two conditions is a mandatory requirement for global disease eradication and elimination targets.

    Every case of AFP must have two stool samples collected within 14 days of the onset of paralysis to ensure an accurate laboratory diagnosis. We urge all district surveillance officers to ensure that these samples reach the national laboratory in good condition and within the required timeframe. For suspected measles, laboratory confirmation through blood samples is essential to distinguish it from other rash-causing illnesses. Any confirmed measles case should trigger an immediate investigation of the child’s vaccination history and a localized immunization response. Strengthening routine immunization coverage is the most effective way to protect our children from these preventable diseases.

    Typhoid Fever Status

    Bulletin Analysis

    Typhoid fever surveillance recorded eighteen (18) cases during Week 9, representing a decrease from the sixty-four (64) cases reported in Week 7. While this decline is encouraging, typhoid fever remains a public health concern due to its strong association with contaminated water and food. The eighteen cases reported this week should still be investigated to identify if they belong to a specific geographic cluster. Typhoid is an enteric fever that can cause severe illness if not treated promptly with appropriate antibiotics. Laboratory confirmation using blood culture remains the gold standard for diagnosis and is encouraged wherever possible at the district level.

    Public health interventions should focus on improving water quality and promoting safe food handling practices in areas where cases are reported. The recent introduction of the Typhoid Conjugate Vaccine (TCV) into the routine schedule is expected to significantly reduce the long-term burden of the disease. We urge all parents to ensure their children receive the TCV to provide them with lasting protection against this infection. District health teams should also monitor for any signs of antibiotic resistance in the typhoid strains isolated in their areas. Continued vigilance and multi-sectoral coordination are required to eliminate typhoid as a public health threat in Malawi.

    V. Summary of Recommendations

    1. Timeliness Improvement

    Specific hospitals including Kamuzu Central and Queen Elizabeth must address internal reporting delays to meet the national timeliness target of 100%.

    2. Malaria Mortality Review

    Districts with malaria deaths must conduct thorough clinical reviews to ensure adherence to severe malaria management protocols and availability of artesunate.

    3. Cholera Preparedness

    Intensify community surveillance and water quality monitoring in districts reporting suspected cholera cases to prevent localized outbreaks.
