Niger and Nigeria were the countries with the highest number of cases and, in the case of Niger, higher lethality rates.
Vaccination status: Partially (P) and fully (T) vaccinated countries are noted. The lack of reported deaths in Nigeria might suggest effective vaccination or control measures.
Data completeness: Varies by country, with only partial or no data for some regions.

Niger: High attack rates in Niamey districts and adjacent areas. Support was extended to districts within the region.
Nigeria: 2 LGAs in epidemic phase (Aliero, Bunza) and 2 in alert. Likely under control in certain areas due to vaccination efforts.
RD Congo: No data due to geographic ineligibility for the meningitis belt.
