Summary of WHO Meningitis Surveillance Report (End of Week 17, 2003)

Key Highlights:
- Niger shows a decreasing trend in meningitis cases and deaths.
- Burkina Faso has only one district under alert status.
- Most countries in the African Meningitis Belt report data from various weeks, with case counts and case fatality rates (CFR) ranging widely (e.g., CFR from 6.7% to 22.3%).
- Pathogen identification is pending or limited for some weeks, particularly for serogrouping and further lab results.
Country-Specific Data:
- Benin: Reports 318 cases and 71 deaths (CFR 22.3%) during W1-W16. Vaccination completed in alert districts; pathogens include Nm W135 and Ad.
- Burkina Faso: Reports 7,146 cases and 1,058 deaths (CFR 14.8%) up to W17; only one district was initially under alert.
- Chad: Reports 468 cases and 72 deaths (CFR 15.4%) through W16; no cases reported in week 16.
- Ghana: Reports 1,340 cases and 169 deaths (CFR 12.6%) through W16; case incidence higher in specific regions like Bole; pathogens include Nm A and W135.
- Mali: Reports 689 cases and 46 deaths (CFR 6.7%) through W17; no active surveillance circle in alert districts.
- Niger: Reports 6,579 cases and 525 deaths (CFR 8.0%) up to W17; case trend decreasing, with several districts returning to alert status.
- Nigeria: Reports 1,804 cases and 227 deaths (CFR 12.6%) up to W15; incomplete data in some areas (e.g., Katsina and Babura districts), no lab data yet.
- Togo: Reports 289 cases and 58 deaths (CFR 20.1%) through W16; limited lab capacity due to reagent unavailability; pathogens include Nesseriae and Meningoccocus.
Overall Trend:
- The surveillance indicates varying epidemic levels across the African Meningitis Belt. High CFRs and inconsistent pathogen data highlight ongoing challenges in case management and laboratory testing, with seasonal patterns influencing case loads.
