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.

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.

More should be done to control the spread of bird flu among animals to avoid more cases in humans, the World Organisation for Animal Health (WOAH) said on Wednesday, following the first death of a patient from the virus in the United States.
