The first U.S. bird flu death has been reported — a person in Louisiana who had been hospitalized with severe respiratory symptoms. State health officials announced the death on Monday, and the Centers for Disease Control and Prevention confirmed it was the nation's first due to bird flu.

The case in Louisiana is the first human death from bird flu in the U.S. during this current outbreak, but there was a death in Mexico back in May 2024 in a patient with no known exposure to farm animals. The case, much like the patient in Louisiana, was in a person with other underlying conditions, though it’s not clear what those may have been.
