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 bird flu, also known as avian influenza and H5N1, was implicated in the first human death from the infectious disease on January 6. But still, no human-to-human transmission has been reported.

The patient, who was older than 65 and had underlying medical conditions, was hospitalized weeks ago in critical condition with severe respiratory illness.
