    I. Performance & Surveillance

    District Reporting Completeness

    Bulletin Analysis

    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.

    I. Performance & Surveillance

    District Reporting Completeness

    Bulletin Analysis The national reporting completeness for Week 4 reached 97.6%, representing a notable improvement from previous weeks. This high level of reporting across the One Health Surveillance Platform (OHSP) indicates that facility-level data entry is becoming more consistent. Most districts have achieved the 100% threshold, ensuring that the epidemiological data is representative of the entire population. Maintaining this momentum is crucial for effective health resource planning and early outbreak detection. However, there are still minor gaps that need addressing to reach absolute completeness nationwide. Zonal Epidemiology Officers are urged to continue their support to facilities that face persistent connectivity or staffing challenges. Consistent reporting at this level provides the solid evidence base needed for national public health decision-making.

    Timeliness Performance

    Bulletin Analysis Timeliness of reporting for Week 4 stands at 94.6%, showing a significant positive trend in the speed of data submission. While this is an excellent achievement, specific districts including Balaka, Karonga, Mzimba South, and Machinga DHOs have been flagged for needing improvement. Timely data is the lifeblood of the IDSR system, as even a 24-hour delay can impact the speed of a life-saving response. We continue to emphasize that data should be validated and verified by IDSR coordinators as soon as it is entered into the system. Addressing the bottlenecks in these lagging districts remains a priority for the National IDSR Secretariat. Improved timeliness ensures that alerts are acted upon while they are still manageable at a local level. Sustained technical support will be provided to ensure all districts meet the 100% timeliness target consistently.

    EBS Signal Distribution

    Bulletin Analysis A total of 18 Event-Based Surveillance (EBS) signals were reported during this week, underscoring the vigilance of community and facility-level actors. These signals represent unusual health events that require rapid verification to determine their public health significance. It is mandatory that District Rapid Response Teams (DRRTs) conduct thorough risk assessments for all 18 verified signals without any further delay. Community engagement remains the primary driver of these signals, and maintaining trust with local leaders is essential for ongoing detection. The variety of signals reported this week highlights the broad spectrum of health threats being monitored beyond routine diseases. We encourage all districts to continue refining their signal detection mechanisms to capture potential outbreaks at their earliest stages. Timely assessment of these events is critical to prevent small clusters from escalating into widespread emergencies.

    II. Disease Morbidity

    Malaria Cases (Week 4)

    Bulletin Analysis Malaria remains the most significant burden on the health system, with 51,408 cases and 8 reported deaths during Week 4. This high case volume during the peak transmission season requires vigilant case management and consistent supplies of RDTs and ACTs. While the case count is slightly lower than previous weeks, the increase in mortality highlights the need for early diagnosis. Health facilities must prioritize severe malaria cases for immediate inpatient care to reduce the risk of further fatalities. Community health workers are encouraged to intensify their efforts in promoting the use of long-lasting insecticidal nets (LLINs). We are closely monitoring districts with rising case fatality rates to identify gaps in clinical management protocols. Strengthening the supply chain for antimalarial commodities is essential to ensure no facility runs out during this critical period.

    Bloody Diarrhoea

    Bulletin Analysis Surveillance for bloody diarrhoea recorded 1,279 cases this week, indicating a persistent risk of enteric infections across the country. This condition is a sensitive indicator for potential outbreaks of shigellosis or other serious pathogens linked to poor hygiene. All reported cases should be investigated to identify potential environmental contamination sources, particularly during the rainy season. Strengthening water, sanitation, and hygiene (WASH) interventions in the most affected districts is a top priority. Clinicians are reminded to strictly follow the diagnostic and treatment algorithms for dysentery to ensure appropriate antibiotic use. Laboratory confirmation of a subset of these cases is necessary to monitor for any emerging patterns of antimicrobial resistance. The rise in cases compared to earlier weeks necessitates intensified community education on food safety and handwashing.

    Typhoid Fever Trends

    Bulletin Analysis Typhoid fever surveillance recorded 36 cases this week, showing a decrease compared to the mid-January spike but requiring continued monitoring. Typhoid transmission is often localized, making it essential to conduct environmental audits in areas where clusters of cases appear. Ensuring access to safe drinking water and promoting household water treatment remain the most effective prevention strategies. Public health officials should collaborate with water boards to address any infrastructure failures contributing to contaminated supplies. Clinical staff should maintain awareness that typhoid can mimic other febrile illnesses, including malaria, making lab verification vital. We are analyzing the geographic distribution of these cases to target high-risk zones for specific hygiene interventions. Long-term reduction of typhoid depends on sustained investment in sanitation and the potential introduction of typhoid conjugate vaccines.

    III. Critical Alerts & Mortality

    Maternal Deaths (N=7)

    Bulletin Analysis A concerning 7 maternal deaths were reported during Week 4, necessitating immediate and rigorous investigation by the Reproductive Health Department. Each of these deaths must undergo a Maternal Death Surveillance and Response (MDSR) audit within 24 to 48 hours. These audits are critical for uncovering the “three delays”: delay in seeking care, delay in reaching a facility, and delay in receiving adequate care. Identifying the root causes of these deaths is essential for implementing corrective measures to prevent future occurrences. We must ensure that all facilities are equipped with basic and comprehensive emergency obstetric care capabilities. Strengthening the referral system for high-risk pregnancies remains a cornerstone of our strategy to lower maternal mortality. Every maternal death is a sentinel event that indicates a need for systemic improvement in maternal healthcare services.

    SARI Mortality (Week 4)

    Bulletin Analysis There were 83 cases of Severe Acute Respiratory Infection (SARI) reported this week, with 1 confirmed death. SARI surveillance is vital for monitoring the circulation of respiratory pathogens, including seasonal influenza and COVID-19. Clinicians should be particularly vigilant in identifying respiratory distress in pediatric and elderly populations who are at higher risk. Early clinical intervention, including oxygen support and appropriate antibiotics for secondary infections, is key to reducing mortality. We are currently analyzing viral samples from SARI cases to detect any shifts in circulating strains or potential new threats. Infection prevention and control (IPC) measures in hospitals must be strictly enforced to prevent nosocomial transmission of respiratory viruses. Continued public messaging on respiratory hygiene is necessary to mitigate the spread within the community.

    AEFI Surveillance

    Bulletin Analysis A total of 103 Adverse Events Following Immunization (AEFI) were reported, which reflects the high activity level of our national immunization programs. The vast majority of these cases represent minor, non-serious reactions that are typical of standard vaccines. This high reporting rate is actually a positive indicator of a sensitive and transparent safety monitoring system. It demonstrates that health workers are committed to the careful follow-up of all vaccinated individuals and are documenting all reactions. Maintaining this level of surveillance is essential for building and sustaining public trust in vaccine safety across all age groups. Any serious or unusual AEFIs are immediately referred to the National AEFI Committee for expert investigation. This rigorous approach ensures that the benefits of immunization continue to far outweigh any risks.

    IV. Vaccine Preventable & Special Events

    Mpox Alerts (Week 4)

    Bulletin Analysis For Week 4, there were zero new confirmed cases of Mpox, but the surveillance system generated 7 new alerts. This indicates that clinicians and community members remain on high alert for symptoms such as unexplained rashes or lesions. Rapid verification and laboratory testing of these alerts are essential to ensure any potential introduction of the virus is caught early. We continue to monitor the regional situation closely, as the threat of cross-border transmission remains significant. Health workers must maintain high standards of IPC when managing suspected cases to protect themselves and other patients. Public awareness efforts should focus on encouraging individuals with suspicious symptoms to report to the nearest health facility immediately. This proactive stance is our best defense against a potential Mpox outbreak within our borders.

    AFP (Polio) & Meningitis

    Bulletin Analysis Six cases of Acute Flaccid Paralysis (AFP) were reported this week, highlighting the critical importance of our ongoing Polio surveillance. Each AFP case must be investigated within 48 hours, and two stool samples must be collected to rule out poliovirus. Additionally, 5 cases of Meningococcal meningitis were recorded, which requires immediate clinical action and contact tracing. Meningitis is a medical emergency that demands rapid diagnosis through lumbar puncture and the initiation of life-saving antibiotics. We are monitoring these cases to identify any potential clusters that could indicate a localized outbreak. Ensuring that our laboratory systems can quickly identify the specific strain of meningitis is vital for guiding the public health response. High routine immunization coverage remains the most effective long-term protection against both of these serious conditions.

    Measles & Cholera Status

    Bulletin Analysis Measles surveillance and cholera containment remain high-priority areas as we move through the first quarter of 2026. Measles clusters are being closely monitored, with a focus on districts that have historically shown lower immunization coverage. Achieving and maintaining 95% coverage with two doses of the Measles-Rubella (MR) vaccine is essential for herd immunity. Regarding cholera, although cases have fluctuated, the risk remains high in districts with poor sanitation and during periods of heavy rainfall. Multi-sectoral collaboration between health, water, and local government is the only way to effectively contain cholera outbreaks. Reactive vaccination campaigns and the strengthening of oral rehydration points are key components of our current response strategy. We urge all partners to continue supporting these critical interventions to protect the most vulnerable populations from these preventable diseases.

    V. Summary of Recommendations

    1. Timeliness Priority

    Balaka, Karonga, Mzimba South, and Machinga DHOs must urgently improve their reporting timeliness to meet national standards.

    2. Maternal Health Audit

    The Reproductive Health Department must investigate all 7 maternal deaths reported this week to identify and address service delivery gaps.

    3. EBS Verification

    District Rapid Response Teams (DRRTs) must conduct immediate risk assessments for all 18 verified EBS signals to prevent escalation.

    I. Performance & Surveillance

    District Reporting Completeness

    Bulletin Analysis The national reporting completeness for Week 2 reached a commendable 95.0%, demonstrating strong engagement from most districts. This metric reflects the percentage of expected reports that were successfully entered into the One Health Surveillance Platform (OHSP). However, several key districts like Mangochi and Mzimba South are identified as needing urgent improvement to reach the 100% target. Consistent reporting is the backbone of our early warning system and ensures no local outbreaks are missed. District health management teams are urged to support their data clerks in maintaining these high standards. Without complete data, the PHIM cannot accurately allocate resources or assess the true public health burden across the country. We congratulate the districts that achieved 100% and set a benchmark for the rest of the nation.

    Timeliness Performance

    Bulletin Analysis Timeliness of reporting for Week 2 stands at 87.3%, which is below the desired national performance threshold of 100%. Timeliness is measured by the submission of reports by the designated deadline each Monday, allowing for rapid national analysis. The bulletin highlights that central facilities, including Kamuzu Central Hospital and QECH, must streamline their internal data flows to improve their reporting speed. Delays in reporting directly hinder the National IDSR Secretariat’s ability to trigger immediate responses to emerging threats. Each hour of delay potentially increases the risk of unchecked disease transmission within the community. We are monitoring the barriers to timely submission, including technical issues on the OHSP platform and staff availability. All facility focal persons are reminded that “Time is Health” in the context of surveillance.

    EBS Signal Distribution

    Bulletin Analysis A total of 19 Event-Based Surveillance (EBS) signals were captured during this reporting period, representing a vital layer of our surveillance architecture. EBS focuses on capturing unstructured information about public health events that may not be captured by routine indicator-based reporting. All 19 signals were verified, indicating that the community and health workers are highly vigilant in spotting unusual occurrences. The District Rapid Response Teams (DRRTs) are now tasked with conducting formal risk assessments for every verified event. These signals range from clusters of unknown illnesses to environmental hazards that pose a risk to human health. Strengthening EBS detection at the community level remains a priority for the upcoming quarter. We encourage all districts to continue utilizing the toll-free lines and community structures to report these signals.

    II. Disease Morbidity

    Malaria Cases (Week 2)

    Bulletin Analysis Malaria continues to dominate the morbidity profile of Malawi, with 52,213 cases reported in Week 2 alone. Alarmingly, this high case volume was accompanied by 6 confirmed deaths, emphasizing the need for early diagnosis and treatment. Most districts are currently seeing high transmission rates, typical of the current seasonal trends. The PHIM recommends that all health facilities ensure a steady supply of Rapid Diagnostic Tests (RDTs) and Artemisinin-based Combination Therapy (ACTs). Public health messaging should focus on the consistent use of insecticide-treated nets (ITNs) and seeking medical care within 24 hours of fever onset. Surveillance data shows that children under five and pregnant women remain the most vulnerable populations. Continued monitoring of case fatality rates is essential to evaluate the quality of inpatient care.

    Bloody Diarrhoea

    Bulletin Analysis During Week 2, 1,186 cases of bloody diarrhoea were reported, along with 4 related deaths. This condition is a sensitive indicator for serious enteric pathogens, including those that cause dysentery and cholera. Given the ongoing cholera outbreaks in some regions, every case of bloody diarrhoea must be treated with high clinical suspicion. Health workers are instructed to collect stool samples for laboratory confirmation to identify the specific causative agents. Infection Prevention and Control (IPC) measures must be strictly enforced at the facility level to prevent nosocomial transmission. Safe water, sanitation, and hygiene (WASH) interventions at the community level are the primary defense against these waterborne diseases. The Ministry of Health is working with partners to distribute chlorine and hygiene kits in the most affected districts.

    Typhoid Fever Trends

    Bulletin Analysis Typhoid fever remains a significant concern with 69 cases reported this week, showing a slight upward trend compared to previous weeks. This disease is closely linked to poor sanitation and contaminated food or water sources. Clinical teams are advised to maintain high suspicion for patients presenting with prolonged fever and gastrointestinal symptoms. Accurate laboratory diagnosis via blood culture is encouraged wherever possible to guide appropriate antibiotic therapy. We are also monitoring for signs of antimicrobial resistance, which has been observed in Typhoid strains in the region. Public health teams should investigate clusters of cases to identify common sources of contamination. Improvements in urban and peri-urban water systems are long-term requirements to reduce this burden.

    III. Critical Alerts & Mortality

    Maternal Deaths (N=2)

    Bulletin Analysis Two maternal deaths were reported during Epidemiological Week 2, serving as a somber reminder of the challenges in maternal health. Every maternal death is considered a public health emergency under the IDSR framework and must be reported within 24 hours. A comprehensive Maternal Death Surveillance and Response (MDSR) audit is mandatory for these cases to identify the root causes. These audits look at “three delays”: delay in seeking care, delay in reaching a facility, and delay in receiving appropriate care. The findings from these audits are crucial for implementing systemic changes to prevent future tragedies. We must continue to promote institutional deliveries and ensure that basic emergency obstetric care is available 24/7. Strengthening the referral chain between primary health centers and district hospitals remains a top priority.

    SARI Mortality (CFR 3.4%)

    Bulletin Analysis Severe Acute Respiratory Infection (SARI) surveillance identified 59 cases this week, resulting in 2 deaths. This results in a Case Fatality Rate (CFR) of 3.4%, which requires close monitoring to ensure it does not escalate. SARI surveillance is critical for monitoring the circulation of influenza-like illnesses and potential new respiratory pathogens. All SARI cases should have oropharyngeal or nasopharyngeal swabs collected for virological testing at the national laboratory. Early detection of respiratory outbreaks is essential for preventing wide-scale transmission, especially in crowded environments. Clinical management should focus on early supportive care and oxygen therapy for severe cases. The PHIM is keeping a close watch on these trends as we move through different seasonal patterns.

    AEFI Surveillance

    Bulletin Analysis The 91 cases of Adverse Events Following Immunization (AEFI) reported this week demonstrate a highly active and transparent safety monitoring system. Most of these events were reported as minor reactions, which are expected occurrences in any large-scale vaccination program. High AEFI reporting rates indicate that health workers are properly trained to observe and record any unusual health events post-vaccination. This data is vital for maintaining public trust in the national immunization program. Each serious AEFI is thoroughly investigated by a dedicated committee to determine causality. We commend the districts for their diligence in maintaining these safety standards. Continuous communication with parents and caregivers about what to expect after vaccination helps in managing these events effectively.

    IV. Vaccine Preventable & Special Events

    Mpox Alerts (Week 2)

    Bulletin Analysis While there were zero new confirmed Mpox cases in Week 2, the system successfully generated four distinct Mpox alerts. This signifies that the surveillance system is sensitive enough to catch potential cases for further investigation. Mpox remains a disease of international concern, and Malawi must maintain high levels of vigilance at points of entry and within communities. Health workers are reminded to look for symptoms such as unexplained acute rash, fever, and lymphadenopathy. Prompt isolation of suspected cases and collection of lesion swabs for PCR testing are standard operating procedures. Public awareness campaigns should continue to emphasize the importance of reporting any unusual skin conditions. We are working closely with regional partners to share data and coordinate prevention efforts.

    AFP (Polio) & Meningitis

    Bulletin Analysis Two cases of Acute Flaccid Paralysis (AFP) were reported this week, which are critical for our ongoing Polio-free certification efforts. Every case of AFP in a child under 15 years must be investigated with two stool samples collected 24 hours apart. Furthermore, five cases of Meningococcal meningitis were reported, highlighting the need for rapid diagnostic response. Meningitis can spread quickly in close-contact settings, and immediate laboratory confirmation is required to initiate the correct antibiotic treatment. CSF samples should be transported in Trans-Isolate (TI) medium to ensure the viability of the bacteria. Districts should ensure they have adequate supplies of the necessary collection kits and transport media. Early detection and response to these cases are key to preventing large-scale outbreaks.

    Immunization Outreach

    Bulletin Analysis The Expanded Programme on Immunisation (EPI) data suggests that while routine coverage is stable, outreach strategies need strengthening. Some clusters of vaccine-preventable diseases, such as measles, have been linked to “zero-dose” children who have never been reached by the system. It is vital to map out hard-to-reach areas and schedule regular mobile clinics to bridge the coverage gap. Immunization is the most cost-effective public health intervention available and is the primary tool for reducing child mortality. Cold chain maintenance at the facility level must be monitored daily to ensure vaccine potency. Community leaders and traditional authorities are key partners in encouraging families to complete the full vaccination schedule. We aim for at least 95% coverage for all primary vaccines to maintain herd immunity.

    V. Summary of Recommendations

    1. Reporting Quality

    Kamuzu Central, Mangochi, Mzimba South, and QECH must address timeliness issues immediately.

    2. Cholera Containment

    All partners and government ministries must collaborate to contain ongoing cholera outbreaks through WASH and case management.

    3. EPI Strengthening

    Focus on routine immunization to prevent measles clusters, particularly in areas with lower historical coverage.
