The Louisiana Department of Health reports the patient who had been hospitalized with the first human case of highly pathogenic avian influenza (HPAI), or H5N1, in Louisiana and the U.S. has died. The patient was over the age of 65 and was reported to have underlying medical conditions. The patient contracted H5N1 after exposure to a combination of a non-commercial backyard flock and wild birds.

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