The CDC is calling for expanded testing of bird flu after a child in California tested positive for the virus despite no known contact with animals.

WATERFORD, Mich. (FOX 2) - One man is being tested after being exposed to Bird Flu from infected chickens in Waterford. A case of highly pathogenic avian influenza was confirmed on Thursday, and was detected in a backyard flock.It is the second case of HPAI in Oakland County since the virus was first detected in Michigan back in 2022.

By Leah Douglas and Tom Polansek (Reuters) -People hospitalized for flu should be tested for bird flu within 24 hours, the U.S. Centers for Disease Control and Prevention said on Thursday, in an expansion of the agency's efforts to tackle ongoing infections in humans.

CDC officials say they extended the guidance now because they are seeing more H5N1 patients whose illness they cannot track back to an infected bird or cow.
