- Cameroon: Est region, Lomé and Mouloundou districts (AR 4.1 and 5.7 cases/100,000).
- Ghana: Upper West region, Wa West and Lawra districts (AR 5.8 and 4.6 cases/100,000).
- Nigeria: Gombe and Yobe states (AR 5.7 and 7.6 cases/100,000).

Total suspected cases for the week: Varies by country, e.g., Nigeria reported 441 cases.

Total suspected cases reported by 24 countries: 4,033.
Deaths: 214 (case fatality rate 5.3%).
Countries with data: Benin, Burkina Faso, Cameroon, etc. highlighted for trends.

Pathogens identified in samples: Neisseria meningitidis C (NmC) 40.5%, Streptococcus pneumoniae (Spn) 40.1%, other pathogens like NmW, Hi non-b, etc., accounting for 34.3% of 1,239 tested samples.
Recommendations: Improve surveillance by encouraging lumbar punctures, better sample transportation, and acquiring necessary lab supplies; increase lab capacity for pathogen identification.

Enhance routine surveillance integration, vaccination programs (e.g., MenAfriVac and Men5CV), and emergency response planning.
Strengthen laboratory systems, including RT-PCR setup and mRNA typing for pathogen monitoring.
Immediate actions: Prepare for alert threshold crossings, improve sample handling, and coordinate with WHO for supplies and guidance.
Long-term efforts: Sustain vaccination impact, pre-position vaccines in at-risk areas, and involve CSOs in prevention.

No epidemic districts reported; 49 districts crossed alert thresholds in five countries.
Laboratory data from 10 countries showed high isolation rates, with Uganda reporting recently.
