An inmate at a state correctional facility in Delta County, Colorado, has tested positive for avian flu, also known as H5N1 flu, the Colorado Department of Public Health announced on April 28.
The unnamed man, 40, tested positive for the flu earlier this week following a nasal swab test and the result was confirmed by the Centers for Disease Control and Prevention (CDC) on Thursday.
Repeat testing on the person was negative for influenza, officials said.
According to the department of public health, the man, who is largely asymptomatic and has only reported fatigue, tested positive after being in close contact with infected poultry. Officials noted that the virus may have been present in his nose without causing infection.
