Epidemiological Situation Week 36-39 (31 Aug - 27 Sep 2009)

• No district reported alerts or epidemics.
• Total cases: 325, deaths: 36, case fatality rate: 11.1%.
• Notable high lethality in Benin (25.0%), Burkina Faso (10.9%), and Cote d'Ivoire (12.5%).
• No major deviations from the previous month.
• Recommendation: Improve case management to decrease lethality.

Annual Synthesis 2009 (Weeks 1-39)

• Total cases: 81,635, deaths: 4,512, overall case fatality rate: 5.5%.
• Some countries, like Nigeria (4.4%), showed persistent high lethality.
• Data completeness and timeliness are insufficient; encourage reporting for all weeks.
• PCR tests positive for pathogens in only 46% of samples, indicating poor lab data quality; continue efforts to increase sample analysis.

Key Actions

• Prioritize surveillance improvements and case management to reduce mortality.
• Address data gaps and strengthen laboratory reporting.
