West Nile virus in Culex mosquitoes and dead birds from the San Gabriel Valley, California, 2021–2022
摘要
West Nile virus (WNV) continues to circulate in the United States and infects humans and animals. Constant vector and environment surveillance is essential for public health protection. We generated WNV genome assemblies from dead birds and Culex quinquefasciatus mosquitoes collected in 26 cities in Los Angeles County, California, USA, in 2021–2022. We report molecular surveillance of arboviruses, human cases, and genomic and phylogenetic analysis. Our study contributes WNV genome sequence data from mosquitoes and dead birds in southern California in two recent years, providing information about WNV genetic divergence and virus evolution.
