报告摘要

Overall Statistics: By September 2024, the cumulative number of laboratory-confirmed human cases of avian influenza A(H5N1) reported to WHO is 904, with 464 deaths included in the total count. WHO includes cases from asymptomatic individuals and considers exposure from infected birds or contaminated environments, but confirms all cases only in laboratories.
Period Breakdown:
- 2003-2009: 468 confirmed cases and 282 deaths.
- 2010-2014: 233 confirmed cases and 125 deaths.
- 2015-2019: 145 confirmed cases and 42 deaths.
- 2020-2024: Includes data for individual years up to 2024, but overall cumulative cases reach 904 as of 2024.
Key Countries with High Burden: Egypt (359 cases, 120 deaths), Cambodia (72 cases, 43 deaths), Viet Nam (129 cases, 65 deaths), Indonesia (200 cases, 168 deaths), and China (56 cases, 32 deaths) report significant numbers. Other countries like Australia, Azerbaijan, and Pakistan have fewer cases, with cases sometimes reported inconsistently.
Notable Notes: Cases and deaths are aggregated by reporting country, and the data includes only laboratory-confirmed infections. In some instances, confirmation of infection versus viral presence from exposure remains inconclusive.
