Wild Bird Avian Influenza Surveillance - USDA

Wild bird samples are routinely collected by the USDA APHIS WS National Wildlife Disease Program and screened for avian influenza virus (AIV). Wild bird H5 and H7 AIVs can spillover into domestic poultry where they can exist as low pathogenic viruses or mutate to high pathogenicity, which can cause high mortality. Data presented in the dashboard can help identify increased AIV risk.

美国农业部动植物卫生检验局野生动物服务处（USDA APHIS WS）下属的国家野生动物疾病项目会常规采集野生鸟类样本，并针对禽流感病毒（avian influenza virus, AIV）开展筛查。野生鸟类携带的H5、H7亚型禽流感病毒可跨物种传播至家禽种群，既可能以低致病性毒株的形式存在，也可突变为高致病性毒株，进而引发高致死率疫情。本仪表板所展示的数据可帮助识别禽流感病毒感染风险的上升态势。
