A southwest Louisiana resident has been hospitalized with the state’s first recorded case of bird flu, or H5N1, a highly pathogenic strain of avian influenza the patient contracted after exposure to sick and dead birds, the Louisiana Department of Health announced Friday.

LDH said 60 human cases have been reported nationwide as of Dec. 13, all linked to contact with infected animals. No human-to-human transmission has occurred in the U.S.

Just days after the USDA issued a new order that all raw milk must be tested for bird flu, reports have emerged of animals dying of the virus, including cats and several zoo animals.

Cats "shed the virus through both respiratory and digestive tracts, potentially creating multiple routes of exposure to humans," the researchers wrote.
