Louisiana Reports America’s First Bird Flu Death: A Wake-Up Call for Public Health
The United States has reported its first human fatality from H5N1 avian influenza. The patient, a Louisiana resident over 65 with underlying health conditions, contracted the virus through exposure to infected wild birds and a non-commercial backyard flock.
This case is significant as it marks the first severe human infection of H5N1 in the U.S. Since 2022, the country has documented 66 human infections, primarily among agricultural workers, with most cases being mild.
The Centers for Disease Control and Prevention (CDC) conducted genetic sequencing of the virus from this patient, identifying rare mutations that likely developed during the infection.
These mutations were not present in the animals that likely transmitted the virus, suggesting they emerged later. While concerning, the CDC notes that such changes would be more alarming if found in animal hosts or early in human infections.
Health officials emphasize that the risk to the general public remains low, as there is no evidence of sustained human-to-human transmission of H5N1.
However, they advise caution for individuals handling birds, recommending the use of personal protective equipment and avoidance of contact with sick or dead birds.
