CDC raises concerns over bird flu mutations in Louisiana patient

In 2024, the U.S. reported at least 66 human cases of bird flu, mostly mild. A Louisiana patient, over 65, was hospitalized with severe respiratory symptoms, prompting concern from the CDC about mutations that may enhance the virus's ability to infect humans. The CDC noted that these mutations could allow H5N1 to bind more effectively to human airway receptors, increasing the risk of human-to-human transmission. However, the overall risk to the public remains low, with no evidence of transmission from the Louisiana patient to others. Experts warn that rising human cases provide more opportunities for the virus to mutate. They emphasize the need for increased testing and monitoring to prevent potential outbreaks, as well as the importance of developing a vaccine for vulnerable populations.
