Highlights:

• Global Situation: 28 countries affected since 2023 began; WHO assesses risk as Very High.
• African Region: Most affected (16 countries). Outbreaks in Burundi, Malawi, Mozambique, and Zimbabwe are stabilizing; Democratic Republic of the Congo (DRC) and Uganda face ongoing challenges.
• Horn of Africa: Cases in Ethiopia, Kenya, and Somalia stabilized; conflict zones in Sudan limit response efforts.

• Cases: 28 countries report cases (vs. 16 in 2022). Malawi and Mozambique are experiencing a downward trend; Haiti remains the worst-affected country.
• Case Fatality Ratio (CFR): Elevated globally (1.9% in Africa) due to late diagnosis, inadequate treatment, and disruptions from climate events/conflict.

Key Challenges:

• Shortages of vaccines, cholera kits, and medical personnel
• Difficulty in data collection and reporting (especially conflict zones)
• Strain on response capacities due to multiple concurrent emergencies.

Operational Updates & Next Steps:

• Vaccination: 52 million doses requested; 21 million approved (41%); campaigns are ongoing in DRC, Ethiopia, Kenya, Malawi, Mozambique, and Haiti.
• Response: WHO is supporting with experts, logistics, and technical guidance for surveillance/strengthening laboratories.
• Coordination Strategies: Reactive vaccination campaigns prioritize at-risk areas; focus on decentralizing care and improving community engagement.
