Influenza A Prevalence and Subtype Diversity in Migrating Teal Sampled Along the United States Gulf Coast.

ABSTRACT: Wild birds in the order Anseriformes are important reservoirs for influenza A viruses (IAVs); however, IAV prevalence and subtype diversity may vary by season, even at the same location. To better understand the ecology of IAV during waterfowl migration through the Gulf Coast of the United States (Louisiana and Texas), surveillance of blue-winged (Spatula discors) and American green-winged (Anas carolinensis) teal was conducted. The surveillance was done annually during the spring (live capture; 2012-17) and fall (hunter harvested; 2007-17) at times inferred to coincide with northward and southward movements, respectively, for these waterfowl species. During spring migration, 266 low pathogenicity (LP) IAV positive samples were recovered from 7547 paired cloacal-oropharyngeal
