"Intercontinental movement of H5 2.3.4.4 Highly Pathogenic Avian Influenza A(H5N1) to the United States, 2021" Bits I found interesting: > The initial US detection was from a sample collected on December 30, 2021 from a wigeon in Colleton County, South Carolina (A/American_wigeon/South_Carolina/AH0195145/2021(H5N1), GISAID [https://www.gisaid.org https://www.gisaid.org] accession no. EPI_ISL_9869760). Immediately following this initial detection, there was an additional wild bird detection in South Carolina (A/bluewinged_teal/South_Carolina/AH0195150/2021(H5N1), GISAID accession no. EPI_ISL_9876777) and detections in neighboring North Carolina (Figure 1). Within six weeks there were 137 additional detections in wild birds, indicating high susceptibility to a novel virus and continued dispersal. All birds were apparently healthy hunter harvested dabbling ducks. There was no detection of North American lineage IAV in any of these samples. ---------------------- State - Wild bird species - Number of Clade 2.3.4.4.
