NEW YORK — A Michigan farmworker has been diagnosed with bird flu — the second human case associated with an outbreak in U.S. dairy cows.
The first case happened in late March, when a farmworker in Texas was diagnosed in what officials called the first known instance globally of a person catching this version of bird flu from a mammal. That patient also was treated with an antiviral drug and reported eye inflammation. That hasn't happened, although there's been a steady increase of reported infections in cows. As of Wednesday, the virus had been confirmed in 51 dairy herds in nine states, according to the U.S. Agriculture Department.
