Health authorities in Colorado reported the first U.S. case of a human infected with the bird flu H5 virus this week as the country as a whole faces a huge bird flu outbreak across poultry farms.

The person infected, described as an adult male younger than 40 who was working at a farm with infected poultry, is said to be largely asymptomatic and experiencing only fatigue, the Colorado Department of Public Health & Environment (CDPHE) said on Thursday.
