LOS ANGELES, May 30 (Xinhua) -- A second human case of highly pathogenic avian influenza (HPAI) A (H5) virus infection has been identified in the state of Michigan, marking the third human case associated with an ongoing multistate outbreak of A (H5N1) in U.S. dairy cows, U.S. health authorities said on Thursday.
The new case is a dairy farm worker with exposure to infected cows, probably resulting from cow-to-person spread, according to the U.S. Centers for Disease Control and Prevention (CDC).
