The article recognizes the jump as very worrisome, but it's also a new development. Milk/dairy infections have apparently been happening for some time now; per quoted headlines: > Utah reported that 8 dairy herds in Cache County were bulk tank positive for H5N1, tested as a result of a B3.13-infected layer flock. Utah is the 15th state with confirmed infections in the U.S. > California reported another 5 B3.13-infected dairy herds with the count as of yesterday standing at 193 (of approximately 400 nationally confirmed infected herds) The testing is a consequence of that situation.
