BATON ROGUE, LA. — The Louisiana Department of Health (LDH) confirmed on Jan. 6 the first human death linked to highly pathogenic avian influenza (HPAI) in the United States. The person was previously hospitalized as the first severe virus case in the country.

The state agency said the person was over 65 and reported underlying medical conditions. LDH noted that the patient contracted H5N1 after exposure to wild birds and non-commercial backyard flocks.

“The department expresses its deepest condolences to the patient’s family and friends as they mourn the loss of their loved one,” LDH stated in its release. “Due to patient confidentiality and respect for the family, this will be the final update about the patient.” 

Health officials in Louisiana have not confirmed any additional HPAI cases in the state. Throughout the country, there has not been evidence of person-to-person transmission.

Public health officials said the risk for the general public remains low, with people who work with birds, poultry or cows having a higher risk of exposure.

On Dec. 26, the Centers for Disease Control and Prevention (CDC) reported a mutation of the H5N1 strain in the Louisiana case was discovered.

Since March 2024, officials have confirmed 66 human H5N1 cases in eight states.
