报告摘要

Cases & Deaths: Up to 26 January 2025, reported cases decreased by 27% (-9,552 cases) from December 2024, totaling 34,799 new cases (cholera and AWD) from 19 countries, with 349 deaths (33% decrease/-102 deaths). No report from Western Pacific Region.
Risk Level: Estimated 1 billion persons at risk globally; current risk rated as "Very High".
Key Challenges: Incomplete data due to underreporting and reporting delays; conflict, displacement, natural disasters (e.g., post-Cyclone Filipo in Mozambique, insecurity in DRC) hinder data collection. Cholera transmission is amplified in rural, flood-affected, and conflict zones.

African Region: Highest cases (17,644), down 13% from Dec 2024. Major contributors: South Sudan (10,833), DRC (3,853), Angola (1,081). No significant decrease in deaths.
Eastern Mediterranean: Cases drop 38%, cases from DRC (6,346), deaths from Sudan (46). Major contributors: Afghanistan, Yemen, Sudan, Pakistan.
South-East Asia: Cases up 33% from Dec, likely due to Myanmar/Yemen not reporting full data.

Vaccination: OCV production stable at 6.2 million doses; demand outstrips supply significantly. 9 emergency requests submitted in 2025 for single rounds (totaling 9 million) to support only highly affected areas.
Surveillance: WHO supports countries with surveillance system assessment/revisions and tools for improved data management with testing.
Coordination: Global coordination activities through GOARN/SBP supported 47 experts to 14 countries for case management and other technical areas.
Other Activities:
- WASH & IPC support ongoing.
- RCCE activities implemented with focus on community engagement coordination.
