| Avian influenza A viruses pose threats to public health and agriculture stability. Historically, each of the four influenza A viruses responsible for pandemics in the last century contained at least one gene segment of avian origin. Migratory waterfowl are natural reservoirs of influenza A viruses and are capable of widespread dissemination. In this study, we aim to characterize the antigenic profiles of H3 and H7 avian influenza A viruses currently circulating in migratory waterfowl within North America. By understanding the antigenic diversity of these subtypes, we can understand the natural history of influenza evolution and develop potential disease preventive strategies. |
