The version of the virus has been implicated in human infections but had not previously been detected in cows. The news signifies that the H5N1 virus has spilled from birds into cows at least twice. “This is the first detection of this virus genotype in dairy cattle (all previous detections in dairy cattle have been HPAI H5N1 clade 2.3.4.4b, genotype B3.13). Genotype D1.1 represents the predominant genotype in the North American flyways this past fall and winter and has been identified in wild birds, mammals, and spillovers into domestic poultry,” the department said.
