Meningitis Weekly Bulletin Summary

• Bulletin Period: Covers weeks 44 to 47 of 2011, spanning from October 31 to November 27, 2011.
• Epidemiological Overview for Week 44-47: The situation remains calm across meningitis belt countries, with low case counts. Key countries reporting include Benin, Burkina Faso, Ghana, Mali, Niger, Nigeria, and Togo. Notable fatality rates are: Burkina Faso (11.3%), Ghana (76.6%), Niger (30.8%), Togo (23.1%), and an overall regional average of 19.5% deaths. No widespread epidemics were reported.
• Yearly Summary (Weeks 01-47, 2011): A total of 22,000 suspected meningitis cases were reported, with 1,979 deaths, resulting in a low cumulative fatality rate of 9.0%. Completeness of district-level reporting was high but varied, and contingency plans for epidemics should be updated for 2012. Plans are already in place to stockpile resources in at-risk zones.
• Pathogen Identification: Streptococcus pneumoniae and Neisseria meningitidis W135 were dominant pathogens in specific countries. Recommendations include equipping laboratories with transport and conservation tools to improve CSF specimen processing.
• General Recommendations: Surveillance efforts should be reinforced in 2012 by collecting CSF specimens to identify pathogens, and lab capacities should be strengthened for better case-based surveillance.
