近期全球哺乳动物及人类H5亚型高致病性禽流感疫情风险预警

Early Warning for Current Risk of Global HPAI H5 Subtype Outbreaks in Mammals and Humans

根据世界动物卫生组织(WOAH)数据库和世界卫生组织(WHO)通报数据,2020年至2023年上半年,H5亚型高致病性禽流感病毒已在25个国家引发310起哺乳动物疫情和70例人间病例,动物感染疫情和人间病例分布于欧洲、亚洲、美洲和非洲,感染动物包括家养犬猫以及赤狐、狼等多种陆生哺乳动物,也包括海狮、海豹等海洋哺乳动物,且动物感染疫情仍在持续发展。本文对报告的动物疫情和人间病例,从地理、时间、NA亚型和动物种类分布等方面进行了统计分析,并提出了风险预警和管理建议,以期为我国做好应急预案提供数据和理论支持。

From 2020 to the first half of 2023,according to the database of World Organization for Animal Health(WOAH)and the data notified by World Health Organization(WHO),310 mammal outbreaks and 70 human cases had been caused by highly pathogenic avian influenza virus(HPAI)H5 subtype in 25 countries,covering Europe,Asia,the Americas and Africa,involving domestic dogs and cats,red foxes,wolves and other terrestrial mammals,as well as sea lions,seals and other marine mammals,and the outbreaks were still continuously prevalent in animals.The reported animal outbreaks and human cases were summarized and analyzed in the paper from the distributions of geography,time,NA subtype and animal species,recommendations about early warning and risk management were proposed,with a view to providing data and theoretical support for preparation of emergency response plans in China.
