In 2021, an H7N3 avian influenza virus (AIV) was isolated from a mallard in Tianhewan Yellow River National Wetland Park, Ningxia Hui Autonomous Region, China. Sequences analysis showed that this strain received its genes from H7, H6, H5, H3, and H1 AIVs of domestic poultry and wild birds in Asia and Europe. It was mild pathogenicity in mice. These results suggest the importance of continued surveillance of the H7N3 virus to better understand the ecology and evolution of the AIVs in poultry and wild birds and the potential threat to humans.
2021年，在中国宁夏回族自治区天河湾黄河国家湿地公园的一只绿头鸭中分离出一株H7N3禽流感病毒（AIV）。序列分析表明，该毒株的基因来自亚洲和欧洲家鸡及野生鸟类的H7、H6、H5、H3和H1禽流感病毒。它对小鼠具有轻度致病性。这些结果表明持续监测H7N3病毒对于更好地了解家禽和野生鸟类中禽流感病毒的生态学和进化以及对人类的潜在威胁具有重要意义。
