Bird flu jumps from birds to human in Louisiana; patient hospitalized

A person in Louisiana has been hospitalized with H5N1 bird flu after contact with sick birds, marking the first human case of the virus in the state. The case is currently classified as "presumptive" pending confirmation from the CDC. Health officials have stated that the public risk remains low but advise avoiding sick or dead birds. The patient had interactions with both backyard and wild birds, although their condition has not been disclosed due to confidentiality. This incident is part of a broader trend, as H5N1 has been affecting various bird populations in the U.S. since early 2022 and has recently been found in mammals, including dairy cows. While there have been at least 60 human infections in the U.S. this year, most cases have been mild and primarily among poultry and dairy workers. Experts warn that H5N1 could mutate to become more dangerous to humans, especially if it were to reassort with seasonal flu viruses. Historically, H5N1 has a high case fatality rate, but the reasons for the mildness of recent U.S. cases remain unclear.
