On January 6, 2025, the Louisiana Department of Health (LDH) announced the first human death from bird flu reported in the USA caused by highly pathogenic avian influenza (HPAI) H5N1. The patient, who was over 65 and had preexisting health issues, was exposed to both wild birds and a non-commercial backyard flock before contracting the virus.

This is the first H5N1-related fatality in the United States, and the patient had been in the hospital since mid-December. The patient was previously recognized by the Centers for Disease Control and Prevention (CDC) as the first severe case of H5N1 illness in the nation.

There have been no new reports of cases or evidence of person-to-person transmission, and there is still little risk to the public’s health. However, there is a greater risk for persons who work with cattle, chickens, or birds.

Precautionary Measures and Government Response

In order to minimize cross-contamination, LDH advised consumers to prepare chicken and eggs carefully and stressed the importance of avoiding close contact with wild birds or diseased animals. Additionally, if exposed to ill birds or impacted farms, the Department recommended avoiding raw milk or cheese from diseased animals and checking for conjunctivitis or respiratory problems.

More broadly, the federal government recently spent $306 million to improve H5N1 research and monitoring. While acknowledging the low risk to people, Health Secretary Xavier Becerra emphasized the importance of being ready for any alterations that may increase the virus’s human transmissibility, especially following the human death from bird flu reported in the USA.

Global and Historical Context of H5N1

Since it was first discovered in 1996, H5N1 has spread quickly among bird flocks, and in recent years, an increasing number of animal species have also been impacted. The World Health Organization has reported over 950 instances worldwide since 2003, half of which have been fatal, while the CDC reported 66 human cases in the United States in 2024.

Authorities in India have issued a red warning for zoos in Maharashtra after recent H5N1 infections killed three tigers and a leopard at the Balasaheb Thackeray Gorewada International Zoological Park near Nagpur. Experts continue to worry that the virus may change into a more infectious form and become a serious worldwide threat.
