The death in Louisiana — involving a person with underlying health conditions — is the first human case in the United States linked to exposure to backyard birds, according to the federal Centers for Disease Control and Prevention.

The LDH revealed that the patient was over age 65, had underlying medical conditions and contracted bird flu after exposure to both wild birds and a non-commercial backyard flock.

The first human patient in the United States with a confirmed case of avian influenza has died, according to a press release from the Louisiana Department of Health. The individual was older than 65 years and had underlying medical conditions and remains the only known human case in the state.
