Summary of WHO MDSC Report: Meningitis Epidemiological Situation Week 03, 2005

Overview

This report from the World Health Organization Multi-Disease Surveillance Centre (WHO MDSC) provides an update on the epidemiological situation for meningitis in the African WHO region during week 03 (January 17-23, 2005). It includes case counts, lethality rates, alert status, and germline analysis, with data compiled from various countries. The situation is summarized, and comparative trends with 2004 are mentioned.

Key Findings

No districts reached the alert or epidemic threshold during the week.
Total cases reported were 380 across various countries, with 56 deaths and a case fatality ratio (CFR) of 14.7%. Key pathogens identified included Neisseria meningitidis serogroup W135 (NmW135) and Haemophilus influenzae type b (Hib).
In Chad, cases originated from refugee camps, with vaccination campaigns using the polysaccharide trivalent ACW vaccine ongoing from January 26 to February 6, 2005.
Overall, the epidemiological situation is calm across all countries for this week.

Country-Specific Data

Burkina Faso: Completed surveillance for weeks 1-3, with high case counts and partial completeness.
R.D. Congo: Higher case numbers and lethality rate noted in the synthesis.
Tchad: Active vaccination campaign in camps; districts showed case incidence with low lethality.
Other countries (e.g., Benin, Burkina Faso, Mali, Niger, Côte d'Ivoire) reported lower cases or no activity in some periods.

Synthesis and Trends

The synthesis of reported weeks indicates a general calm situation, with varying completeness of data and overall low epidemic alerts.
Comparative graphs for 2004-2005 show weekly case distributions for countries that provided data, revealing fluctuations but no significant escalations or decreases highlighted. Data comparability is limited due to reporting inconsistencies.

Conclusion

No epidemic alerts or widespread meningitis cases were reported. Preventive measures, such as vaccination, are in place in specific areas to mitigate risks, and ongoing surveillance is recommended for monitoring trends.
