Bird flu detected in Michigan dairy worker

A Michigan dairy worker has been infected with a highly virulent bird flu, the second human case in less than two months of the H5N1 virus circulating among dairy cows.

Federal officials said Wednesday the case does not change their assessment that the risk to the general public remains low. But in a sign of increased urgency, they announced additional financial incentives for dairy producers to expand testing of cattle and accelerated the timetable to ready nearly 5 million doses of vaccine in case the virus becomes more widespread among people.
