正在发生什么

Avian influenza A(H5N1) is being tracked worldwide mainly as an animal-health problem with occasional human spillover, not as a documented human-to-human epidemic. In the latest WHO notice returned here, published on 5 July 2025 about Cambodia, WHO said 986 human cases and 473 deaths had been reported globally from 2003 to 1 July 2025. On this page, media reports list 257 confirmed cases and 101 deaths, unverified, and +1 media this week. In the last 7 days, media and tracker items have described a reported first H5N1 detection in dairy cattle in Washington state, the first bird-flu outbreak of the 2026/27 season on the Isle of Lewis in Scotland, port checks after a reported outbreak in Suriname, and renewed poultry concern in India. WHO notices and recent local reporting describe investigations, surveillance and contact follow-up for human exposures, along with farm biosecurity, safe handling or culling of affected poultry, worker monitoring, public advice, and other containment steps around animal outbreaks.

谁会受影响以及如何传播

禽流感A(H5N1)是一种主要感染鸟类的流感病毒，但有时也会感染人类。向世卫组织报告的大多数人类感染均发生在与病鸟或死鸟、其他受感染动物或受污染环境的密切接触后。世卫组织表示，这些感染通常是零星的，而非持续的人际传播链，且返回的通报中未记录持续的人传人传播。人类疾病表现范围从轻微疾病（包括结膜炎）到严重肺炎和死亡，世卫组织表示，职业暴露于受感染动物的人群风险高于普通人群。
