    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.

    I. Performance & Surveillance

    District Reporting Completeness

    Bulletin Analysis

    During Epidemiological Week 7, the national completeness of reporting through the One Health Surveillance Platform (OHSP) was recorded at 96.0% across the country. This represents a minor decline from previous high-performance weeks but remains well above the acceptable national threshold for data collection. High completeness ensures that the epidemiological trends observed are representative of the entire population’s health status at any given time. Health facilities must remain diligent in submitting their weekly reports to prevent gaps in our national surveillance intelligence. We must ensure that the few facilities currently lagging are identified and supported to resume full reporting cycles.

    Moving forward, the focus must shift toward districts that have consistently failed to achieve a 100% reporting rate in the first quarter of 2026. The 4% gap in reporting can often hide localized clusters of infection that could potentially escalate if left unmonitored. District Health Offices are encouraged to conduct data quality audits to ensure that non-reporting facilities are not facing technical barriers. Targeted supervision visits should be prioritized for those health zones where completeness has shown a downward trend over the last three weeks. Sustaining this system requires constant communication between the facility focal persons and the national surveillance secretariat.

    Timeliness Performance

    Bulletin Analysis

    The national timeliness of reporting for Week 7 reached 96.0%, showing a significant and positive improvement compared to the performance in Week 6. This upward trend is a testament to the renewed efforts by district surveillance teams to meet strict reporting deadlines. Timely data submission is the most critical factor in the early detection of disease outbreaks and the deployment of response teams. When data is received within the stipulated period, the Public Health Institute can analyze trends in real-time. This efficiency reduces the lead time between an event occurring and the implementation of life-saving public health interventions.

    Despite this success, a few specific districts and central hospitals still struggle to maintain consistency in their reporting times. Facilities that report late effectively blind the surveillance system to potential threats emerging in their respective catchment areas. The Ministry of Health continues to monitor these bottlenecks to determine if they are caused by internet connectivity issues or staffing gaps. It is essential that all reporting units recognize that a late report is significantly less valuable for emergency response than a timely one. Zonal coordinators must continue providing hands-on support to the facilities that are currently falling behind the national average.

    EBS Signal Distribution

    Bulletin Analysis

    A total of eighteen (18) Event-Based Surveillance (EBS) signals were reported during Week 7, demonstrating an active community-based detection system. These signals are vital as they often capture unusual health events that routine indicator-based surveillance might overlook initially. The detection of eighteen signals suggests that the community and health workers are maintaining a high level of vigilance for public health threats. Each signal represents a potential starting point for an outbreak that requires immediate verification and assessment by local teams. This proactive approach is the cornerstone of Malawi’s commitment to the International Health Regulations guidelines.

    Once a signal is verified, the District Rapid Response Teams (DRRTs) must perform a comprehensive risk assessment to determine the appropriate response. It is not enough to simply report the signal; the system relies on the quality and speed of the follow-up investigation. For Week 7, we urge all districts to ensure that their response logs are updated to reflect the status of these investigations. Any signal that points toward a cluster of unexplained illness or sudden deaths must be treated with the highest priority. Strengthening the linkage between community detection and district-level response is our primary objective for the coming month.

    II. Disease Morbidity

    Malaria Trends (Week 7)

    Bulletin Analysis

    Malaria remains the most significant cause of illness in Malawi, with 38,914 cases reported during this epidemiological week. While the total number of cases has decreased from the previous week, the severity of the situation is highlighted by 14 recorded deaths. This high mortality rate in a single week underscores the need for continued focus on severe malaria management at all levels of care. The data indicates that transmission is still high, particularly in the low-lying and lakeside districts where environmental conditions favor mosquito breeding. Health facilities must ensure they have adequate stocks of Artemisinin-based Combination Therapy and Rapid Diagnostic Tests.

    The National Malaria Control Program must continue to emphasize the importance of prevention through the consistent use of insecticide-treated bed nets. We are also observing that early care-seeking behavior is critical in preventing uncomplicated malaria from progressing to a fatal state. Community health workers are encouraged to intensify their outreach to educate families on recognizing the early signs of malaria in children. Furthermore, health facilities with high case-fatality rates should be targeted for clinical mentorship on the management of severe febrile illness. The secretariat will continue to track these mortality trends to identify any potential gaps in the supply chain or clinical quality.

    Bloody Diarrhoea

    Bulletin Analysis

    In Week 7, a total of 1,024 cases of bloody diarrhoea were reported across the national surveillance network. This figure shows a slight decrease from the 1,072 cases reported in Week 6, indicating a stabilizing trend in enteric diseases. However, the consistent reporting of over a thousand cases per week remains a public health concern regarding water and food safety. Bloody diarrhoea is often an indicator of poor sanitation and can be a precursor to larger outbreaks of bacillary dysentery. It is essential that we do not let our guard down despite the minor decrease in the total number of cases.

    Districts that are reporting high numbers of cases must prioritize laboratory testing to identify the specific pathogens involved in these infections. Understanding whether these cases are caused by Shigella or other bacteria is crucial for determining the most effective antibiotic treatment. We also recommend that local health offices increase their coordination with water and sanitation partners to improve hygiene in the most affected areas. Public health messages should focus on the importance of drinking safe water and the proper disposal of human waste. Targeted interventions in hotspots can significantly reduce the transmission of these diarrhoeal diseases before they spread further.

    Cholera Status (Suspected vs Confirmed)

    Bulletin Analysis

    The cholera situation in Week 7 saw 155 suspected cases and 8 laboratory-confirmed cases reported nationally. Although zero deaths were recorded this week, the increase in suspected cases from 79 in Week 6 to 155 in Week 7 is a clear signal of escalating risk. This doubling of suspected cases requires immediate and intensified surveillance and environmental health actions in all identified hotspots. The presence of confirmed cases proves that the Vibrio cholerae bacterium is actively circulating within certain communities. We must act decisively to break the chains of transmission before the situation evolves into a large-scale national outbreak.

    Response efforts must focus on providing safe water, adequate sanitation, and hygiene promotion in the areas where confirmed cases have been found. It is also imperative that all suspected cases are managed according to the standard cholera treatment protocols to prevent complications. District teams should ensure that all household contacts of confirmed cases are reached with preventive messages and, where necessary, chemoprophylaxis. The national task force is closely monitoring the surge in suspected cases and stands ready to deploy additional resources to the most burdened districts. Timely reporting of any new clusters is essential for the rapid containment of this highly infectious disease.

    III. Critical Alerts & Mortality

    Maternal Deaths (N=1)

    Bulletin Analysis

    One (1) maternal death was reported during Epidemiological Week 7, representing a significant decrease from previous weeks. While the reduction in the number of deaths is encouraging, the target remains zero, as every maternal death is a preventable tragedy. This single case must be investigated with the same level of intensity as a larger cluster of infections. Maternal mortality is a sensitive indicator of the overall quality of the healthcare system and its ability to manage emergencies. We must continue to push for high-quality maternal and neonatal services across all health facilities in Malawi.

    The mandatory Maternal and Perinatal Death Surveillance and Response (MPDSR) audit for this case must be completed within 72 hours. These audits are crucial for identifying the “three delays”: delay in seeking care, delay in reaching a facility, and delay in receiving appropriate care. The findings from this audit should be used to improve clinical protocols and address any logistical gaps identified at the facility. We urge all district health management teams to prioritize the recommendations coming out of these audits to prevent similar occurrences in the future. Continuous training of health workers on obstetric emergency care remains a top priority for the Ministry.

    SARI Mortality (Week 7)

    Bulletin Analysis

    Severe Acute Respiratory Infection (SARI) surveillance recorded 107 cases during Week 7, with zero deaths reported. This is a slight decrease in morbidity compared to the 125 cases and 2 deaths recorded in Week 6. The absence of mortality this week is a positive outcome that suggests improved clinical management or a shift in the severity of circulating pathogens. However, 107 cases still represent a significant respiratory disease burden on the healthcare system. Vigilance must be maintained, especially for children under five and the elderly, who are at highest risk of complications from pneumonia and influenza-like illnesses.

    Health facilities are reminded to continue collecting samples for sentinel influenza surveillance to monitor the types of viruses currently in circulation. Accurate diagnosis and timely treatment with appropriate antibiotics or antivirals are essential for maintaining the zero-mortality trend. We must also ensure that oxygen therapy is readily available in all district hospitals to manage severe cases of respiratory distress. Community sensitization should continue to focus on the importance of early hospital visits for anyone experiencing breathing difficulties or prolonged high fever. The secretariat will continue to monitor SARI trends as we move through the remainder of the high-risk season.

    AEFI Surveillance (1 Death)

    Bulletin Analysis

    In Week 7, a total of 69 cases of Adverse Events Following Immunization (AEFI) were reported, including one (1) recorded death. This represents an increase in the number of cases compared to the 49 reported in the previous week. AEFI surveillance is critical for monitoring the safety of our immunization programs and maintaining public trust in vaccines. The occurrence of a death following immunization is a very rare and serious event that requires an immediate and thorough investigation. Most of the other 68 cases were minor and expected reactions that resolved without complications. We must ensure that all vaccine-related events are captured accurately in our national database.

    The reported AEFI death must be investigated by the National AEFI Committee to determine the causality of the event. It is essential to determine if the death was truly related to the vaccine, an administration error, or a coincidental underlying health condition. Transparency in this process is vital to address any public concerns and to maintain high vaccination coverage rates. District health teams should continue to encourage parents to report any unusual symptoms in children following vaccination. We will provide a detailed report on the findings of the causality assessment as soon as it is concluded by the expert panel.

    IV. Vaccine Preventable & Special Events

    Mpox Status (Week 7)

    Bulletin Analysis

    There were zero (0) new confirmed cases of Mpox and zero (0) new alerts reported during Epidemiological Week 7. This continues the trend of zero activity from the previous week, suggesting that there is currently no active transmission detected in the country. However, given the regional situation, the risk of importation remains a constant threat that requires us to maintain our surveillance at all borders. We cannot afford to become complacent, as the disease can easily be reintroduced through cross-border travel. Our healthcare workers must remain trained and ready to identify any potential suspects that may arrive at our facilities.

    Public health institute teams are continuing to monitor the situation in neighboring countries to inform our national risk profile. We recommend that the screening protocols at major points of entry remain in place and that community surveillance is not relaxed. Any person presenting with a characteristic rash and fever should be isolated and tested immediately as a precaution. Maintaining a high level of preparedness will allow us to contain any new cases quickly if they occur. We will continue to provide weekly updates on the Mpox status as part of our commitment to global health security and national awareness.

    AFP (Polio) & Measles

    Bulletin Analysis

    Surveillance for Acute Flaccid Paralysis (AFP) remained active in Week 7, which is essential for maintaining Malawi’s Polio-free status. AFP is the primary clinical signal we use to monitor for the potential re-emergence of the Polio virus in the community. In addition to AFP, the surveillance system is also monitoring for any clusters of fever and rash that could indicate Measles. Measles remains a significant threat to children who have not completed their routine vaccination schedules. It is imperative that we maintain high sensitivity in our detection systems for both of these vaccine-preventable diseases to protect our progress.

    For every reported case of AFP, two stool samples must be collected within 14 days of the onset of paralysis to ensure an accurate laboratory diagnosis. We urge all surveillance officers to prioritize the timely collection and cold-chain transport of these samples to the reference laboratory. In the case of suspected measles, laboratory confirmation through blood samples is necessary to differentiate it from other febrile rash illnesses. Any confirmed measles case should trigger a localized vaccination campaign to boost immunity in the affected community. Strengthening routine immunization remains our most effective long-term strategy for preventing these diseases from causing significant outbreaks.

    Typhoid Fever Status

    Bulletin Analysis

    Typhoid fever surveillance recorded 64 cases during Week 7, which represents a significant increase from the 29 cases reported in Week 6. This sharp rise in cases is a concerning trend that suggests a breakdown in water or food safety in certain areas. Typhoid is an enteric fever that thrives in environments where clean water is scarce and sanitation facilities are inadequate. The surge in cases this week requires a targeted investigation to identify potential hotspots or contaminated water sources. We must ensure that diagnostic capacity for Typhoid is available at the district level to confirm these cases and guide treatment.

    Clinicians are advised to follow the updated guidelines for Typhoid management to ensure that patients receive the most effective antibiotic therapy. The Ministry of Health is also monitoring the impact of the Typhoid Conjugate Vaccine (TCV) that was recently introduced in the national schedule. We encourage all parents to ensure their children are vaccinated to provide long-term protection against this debilitating disease. Districts with high case counts should prioritize water quality testing and community hygiene education programs. Reversing this upward trend will require a multi-sectoral approach involving water, sanitation, and health partners to address the underlying environmental causes.

    V. Summary of Recommendations

    1. Cholera Upsurge Response

    Districts must immediately scale up interventions in response to the doubling of suspected cholera cases (from 79 to 155) to prevent a major outbreak.

    2. Malaria Mortality Audit

    Conduct clinical audits for the 14 malaria deaths reported this week to identify gaps in severe malaria management and supply chain issues.

    3. AEFI Investigation

    The National AEFI Committee must conduct an urgent causality assessment for the reported death following immunization in Week 7.

    During Week 6, the national completeness of reporting stood at a commendable 97.0% across all districts using the One Health Surveillance Platform. This figure indicates a strong level of engagement from health facility focal persons and data clerks who are consistently uploading surveillance records. While this percentage remains high, there is still a 3% margin of missing data that represents a significant number of health facilities. Sustaining this high level of performance is essential for maintaining the integrity of our national epidemiological database.

    To reach the ultimate target of 100% completeness, district surveillance officers must actively follow up with facilities that have failed to report. These gaps are often caused by technical issues, personnel shortages, or administrative oversights at the local level. It is vital that these specific facilities receive the necessary logistical support to resume reporting. Continuous monitoring and immediate feedback loops will ensure that the surveillance system captures every significant health event across the country.

    Timeliness Performance

    Bulletin Analysis

    The timeliness of reporting for Epidemiological Week 6 was recorded at 91.0%, which is a decrease compared to previous periods. This decline is particularly concerning because timely data is the backbone of any effective outbreak response strategy. Delay in reporting often means that public health actions are initiated too late to prevent further spread of disease. We have observed that several key facilities, including major central hospitals, are struggling to meet the reporting deadlines consistently.

    Specifically, facilities such as Kamuzu Central Hospital and districts like Balaka and Mangochi must investigate the root causes of these reporting delays. The Ministry emphasizes that data must be entered and validated as soon as it is generated at the facility level. Zonal Epidemiology Officers are tasked with providing direct oversight to those districts that have fallen below the 90% threshold this week. Improving timeliness will require a renewed commitment to strict adherence to the surveillance calendar and better internal coordination.

    EBS Signal Distribution

    Bulletin Analysis

    A total of twenty-eight (28) Event-Based Surveillance (EBS) signals were reported during this week, showing a notable increase in signal detection. This increase suggests that community-level surveillance and health worker sensitivity to unusual health events are improving across the districts. EBS is a critical component of our early warning system as it captures signals that might not be detected through routine reporting. The variety of signals reported this week reflects a robust effort to monitor diverse public health threats simultaneously.

    However, reporting the signals is only the first step in a larger process of public health verification. District Rapid Response Teams (DRRTs) are now mandated to conduct comprehensive risk assessments for every one of these 28 verified signals. These assessments must be conducted without any further delay to determine the potential for outbreak or emergency. Failure to investigate these signals promptly could lead to missed opportunities for early containment of infectious diseases or other hazards.

    II. Disease Morbidity

    Malaria Cases (Week 6)

    Bulletin Analysis

    Malaria continues to be the leading cause of morbidity in the country with 48,308 cases reported in Week 6 alone. This volume represents a massive burden on the national healthcare infrastructure and requires constant resource allocation. Eight (8) deaths were unfortunately recorded this week, highlighting the ongoing risk of severe malaria among vulnerable populations. While the total case count has seen a slight reduction from previous weeks, the disease remains highly endemic. The majority of these cases are being treated at the primary healthcare level where diagnostic tools are essential.

    Efforts to control malaria must focus on both prevention and the quality of clinical management for severe cases. The distribution of insecticide-treated nets and indoor residual spraying must be maintained in high-burden districts to drive down transmission rates. Additionally, health workers are encouraged to strictly follow treatment protocols for complicated malaria to prevent further avoidable deaths. The secretariat will continue to monitor malaria trends closely to identify any unusual spikes that may indicate localized outbreaks or resistance patterns.

    Bloody Diarrhoea

    Bulletin Analysis

    A total of 1,072 cases of bloody diarrhoea were reported across the country during Epidemiological Week 6. This figure shows a downward trend from the previous reports, which is a positive sign for the national health system. However, even with the decrease, the presence of over a thousand cases indicates ongoing issues with water and sanitation. Dysentery remains a significant concern in crowded urban settings and rural areas with limited access to clean water. Vigilance must remain high as we are still within the seasonal peak for enteric diseases.

    Public health officials are urged to continue promoting handwashing and the use of safe water to prevent the transmission of these pathogens. Districts reporting the highest numbers of bloody diarrhoea should conduct targeted health education campaigns in the most affected communities. Laboratory confirmation of the causative agents is also necessary to rule out potential outbreaks of Shigellosis or other serious conditions. We must not allow the current downward trend to lead to a relaxation of prevention and control measures.

    Cholera Status (Suspected vs Confirmed)

    Bulletin Analysis

    The cholera situation remains a high-priority public health concern with 79 suspected and 11 confirmed cases reported this week. While there were zero deaths recorded in Week 6, the continued occurrence of confirmed cases indicates active transmission within the environment. Each confirmed case serves as a warning that the underlying conditions for a larger outbreak are still present. The health system must remain in a state of high alert to manage any sudden increase in case numbers. Immediate isolation and treatment are critical to preventing secondary transmission among household contacts.

    Response teams are focusing on intensive WASH (Water, Sanitation, and Hygiene) interventions in the specific communities where confirmed cases have been identified. It is essential that all partners and government ministries collaborate effectively to ensure that clean water supplies are maintained. Public awareness campaigns should be intensified to educate the population on the symptoms of cholera and the importance of seeking care early. The lack of deaths this week is encouraging, but we must maintain this standard through high-quality clinical care and rapid response.

    III. Critical Alerts & Mortality

    Maternal Deaths (N=4)

    Bulletin Analysis

    In Week 6, our surveillance system captured four (4) maternal deaths across different health facilities in the country. Although this is a reduction from the seven deaths reported in Week 4, every single maternal death is considered a sentinel event that requires urgent attention. These deaths represent a profound loss to families and reflect gaps in our maternal health delivery system. The Reproductive Health Department is now responsible for ensuring that each of these cases is thoroughly audited. We must understand the clinical and systemic factors that contributed to these tragic outcomes.

    The Maternal and Perinatal Death Surveillance and Response (MPDSR) audits must be conducted within the stipulated timeframe of 48 to 72 hours. These audits are intended to identify avoidable causes and to formulate actionable recommendations to prevent future occurrences. Health facilities are reminded to prioritize emergency obstetric care and to ensure that referral systems are functioning efficiently. Continuous training for midwives and clinicians on managing obstetric emergencies is also a key recommendation to drive these numbers down to zero.

    SARI Mortality (Week 6)

    Bulletin Analysis

    Severe Acute Respiratory Infections (SARI) have shown a significant increase this week with 125 reported cases and 2 deaths. This sharp rise in morbidity suggests that there is a high circulation of respiratory pathogens in the community. The rainy season often correlates with an increase in viral respiratory illnesses, which can progress to severe pneumonia if not managed. Health facilities must be prepared for an influx of patients presenting with severe respiratory distress. The two deaths recorded indicate that the severity of these infections can be fatal without prompt intervention.

    District health offices must ensure that there is an adequate supply of oxygen and essential antibiotics in all treatment centers. Clinicians should be vigilant in screening patients for SARI and following the established clinical guidelines for management. It is also important to maintain robust testing for influenza and other respiratory viruses to understand the local epidemiology. Public health messages should emphasize the importance of early care-seeking behavior for children and the elderly who develop high fever and breathing difficulties.

    AEFI Surveillance

    Bulletin Analysis

    Surveillance for Adverse Events Following Immunization (AEFI) recorded 49 cases during Epidemiological Week 6. This number is a significant decrease from the 103 cases reported in Week 4, which may reflect a change in the intensity of vaccination activities. AEFI surveillance is essential for maintaining public confidence in national immunization programs and ensuring vaccine safety. Most of the reported cases this week were minor and expected reactions that were successfully managed at the local level. No serious adverse events leading to hospitalization or long-term disability were reported this week.

    Health workers are encouraged to continue reporting all AEFI cases, regardless of their perceived severity. Consistent reporting allows the national regulatory authorities to monitor the safety profile of all vaccines being used in the country. It is important to investigate any clusters of AEFI to rule out issues related to vaccine quality or administration errors. Maintaining a sensitive and transparent AEFI surveillance system is key to addressing vaccine hesitancy and promoting high coverage across all districts. Documentation of these events must be accurate and submitted through the established reporting channels.

    IV. Vaccine Preventable & Special Events

    Mpox Alerts (Week 6)

    Bulletin Analysis

    There were zero (0) new confirmed Mpox cases and zero (0) new alerts generated during Epidemiological Week 6. This lack of activity is a positive development compared to the seven alerts that were investigated in Week 4. It suggests that the immediate risk of transmission may be low at the moment, but we cannot afford to become complacent. The global and regional situation for Mpox remains dynamic, and the risk of importation remains a factor for Malawi. Our surveillance systems at points of entry and in health facilities must remain functional and sensitive.

    Health workers should continue to maintain a high index of suspicion for any patients presenting with unexplained rash and fever. Early detection and isolation of suspect cases are the most effective ways to prevent a localized outbreak from occurring. Public health education on the symptoms of Mpox and how it spreads should continue in high-risk areas. We will continue to monitor the situation and provide updates as soon as new information becomes available. The secretariat remains prepared to reactivate full response protocols should any new signals emerge.

    AFP (Polio) & Meningitis

    Bulletin Analysis

    Surveillance for Acute Flaccid Paralysis (AFP) recorded ten (10) cases this week, which is a high number that demonstrates the sensitivity of our system. AFP surveillance is the primary method for detecting potential Polio cases and is a major requirement for maintaining Polio-free status. Every single case of AFP must be treated as a potential public health emergency until proven otherwise by laboratory results. We also recorded five (5) cases of suspected meningitis, which requires careful clinical and laboratory investigation. These conditions represent serious threats to child health and require immediate action.

    For the ten AFP cases reported, it is mandatory that two adequate stool samples are collected at least 24 hours apart and within 14 days of the onset of paralysis. These samples must be transported under cold chain conditions to the national laboratory for analysis. Surveillance officers are urged to ensure that the 48-hour deadline for sample collection after notification is strictly met. In addition, the suspected meningitis cases should have lumbar punctures performed to confirm the diagnosis and determine the appropriate antibiotic therapy. Strengthening these surveillance activities is essential for national health security.

    Typhoid Fever Status

    Bulletin Analysis

    Typhoid fever surveillance recorded 29 cases in Week 6, continuing a steady but slightly declining trend from previous reporting periods. Typhoid remains a challenge in many districts due to the persistent difficulties in accessing safe drinking water and adequate sanitation. The persistence of these cases highlights the need for integrated environmental health interventions alongside clinical care. Most of these cases are reported from urban and peri-urban centers where population density is high. Laboratory confirmation is often a challenge, so many of these are managed based on clinical suspicion and rapid tests.

    The long-term solution for Typhoid fever involves significant investment in water infrastructure and the promotion of food safety practices. We encourage districts to map out hotspots of Typhoid fever and prioritize these areas for hygiene promotion and water testing. Health workers should also be trained on the updated guidelines for Typhoid management to ensure effective treatment and prevent antimicrobial resistance. The introduction of the Typhoid Conjugate Vaccine (TCV) in the national schedule is a critical step that should be supported by high coverage rates. Monitoring trends will help us evaluate the impact of these vaccination efforts over time.

    V. Summary of Recommendations

    1. Urgent Timeliness Intervention

    Central Hospitals (KCH, ZCH, QECH) and districts like Balaka and Mangochi must investigate and resolve reporting delays immediately.

    2. Cholera Containment

    All districts must collaborate to contain the current cholera threat (11 confirmed cases) by focusing on case management and WASH.

    3. AFP Sample Collection

    Surveillance officers must ensure that all 10 reported AFP cases have adequate stool samples collected and shipped to the lab within 48 hours.
