A Colorado man has tested positive for an H5 bird flu virus, the first such case in the U.S., health officials said April 28.
The Colorado health department said the man, who is younger than 40, had been working on a commercial farm with poultry that, according to the CDC, was presumably infected with H5N1.
He reported fatigue as his only symptom and is now in isolation and being treated with the flu antiviral drug oseltamivir.
It’s unclear whether the exposure resulted in an infection, according to statements from the health agencies. Officials from the Colorado health department said a positive test result came from a single nasal specimen. The CDC confirmed that result April 27, though it said repeat testing has been negative.
