Genetic sequencing of bird flu from a Utah mink farm found a mutation in every sample that is rarely seen in wild birds and also appeared in Spain's 2022 mink outbreak, according to a preliminary genomic report posted Oct. 22, as Nature World News reported. Utah officials have not culled the animals and have stopped actively monitoring farm workers.
The findings arrive as Washington confirms its first H5N1 case tied to a dairy worker. Together, the two outbreaks show the virus moving through mammals in the West, and state responses that vary widely.
The risk to the general public remains low, health officials say, and no person-to-person spread has been found in the United States. The concern centers on workers and their families, and on whether repeated spread in mammals gives the virus more chances to adapt. [emphasis added]
