Outbreak data indicates key resurgent events in 2016/17 and 2020/21 that contributed to the panzootic spread of H5N1 in 2021/22, including an increase in virus diffusion velocity and persistence in wild birds. Genomic analysis reveals that the 2016/17 epizootics originated in Asia, where HPAI H5 reservoirs are documented as persistent. t. e. Influenza A virus subtype H5N1 (A/H5N1) is a subtype of the influenza A virus which can cause illness in humans and many other species. [1] A bird-adapted strain of H5N1, called HPAI A (H5N1) for highly pathogenic avian influenza virus of type A of subtype H5N1, is the highly pathogenic causative agent of H5N1 flu, commonly known as avian Our Flyway camera is located in the Upper Mississippi River National Wildlife and Fish Refuge on Lake Onalaska, in the heart of the Driftless region. It offers an unparalleled look at migrating birds and river wildlife, including Bald Eagles, American White Pelicans, Sandhill Cranes, Caspian Terns, Cormorants, and many species of ducks, gulls These changes can possibly be attributed to the naturally extensive genetic reassortment activity of HPAI H5 viruses; to several contributing factors, such as migratory fowl, flyways, and poultry farming practices, including the distribution of vaccines such as Re-5 (generated from clade 2.3.4 H5N1) in 2008; or a combination of the above Rare Bird, Butterfly Species in the Willamette Valley. Baskett Slough National Wildlife Refuge sits about 14 miles west of Salem and was established in 1965 to help protect the dusky Canada goose. The iconic bird, noted for its slender black neck and white patch around its neck, winters almost exclusively in the Willamette Valley; keep an eye out for the bird on the refuge's farmland all W15VLr.
