Epidemiological Summary for MDSC Meningitis Bulletin (Weeks 40-44, 2009)

During weeks 40-44 (September 28 to November 1, 2009), the epidemiological situation for cerebrospinal meningitis was calm overall. Countries reporting cases included Benin, Burkina Faso, Cameroon, Central African Republic, Côte d'Ivoire, Ghana, Mali, Niger, Nigeria, RD Congo, and Togo. Total cases reported were 566, with 61 deaths, resulting in a lethality rate of 10.8%. Benin had 20 cases and 0 deaths, while other countries showed varying rates, such as Burkina Faso at 23.5% lethality. Comments recommend that countries utilize this pre-epidemic period to acquire necessary drugs, reagents, and vaccines for the 2010 epidemic preparedness plan.

Annual Synthesis (Weeks 1-44, 2009):
Cumulative data for 2009 showed a significant increase in cases and deaths. Total cases were 81,445, with 4,651 deaths and a lethality rate of 5.7%. Countries such as Nigeria reported high volumes (cases: 56,015, deaths: 2,474), while some like Central African Republic and Tchad had elevated lethality rates (16.6% and 10.5%, respectively). Recommendations emphasize improving data completeness and timeliness, as well as enhancing case management to reduce lethality.

Pathogen Identification:
Pathogen identification efforts were ongoing during 2009, with methods including PCR, LATEX, and culture. Total tests and identified pathogens were summarized, but specific country-level data showed variations. Burkin Faso and Nigeria had extensive data, while other countries reported limited results. Comments call for intensified collection and analysis of cerebrospinal fluid specimens to detect unusual situations during future periods.

Additional Insights from the Bulletin:
Graphical representations were referenced but not included in the text. Epidemiological trends from 2008 and 2009 were noted, highlighting the need for continued monitoring. Overall, the bulletin underscores the importance of preparedness and data quality for effective meningitis response.
