The Centres for Disease Control and Prevention disclosed that a Colorado resident in his 40s, tested positive for the H5 bird flu disease, marking the first known confirmed case of the flu in the country.
“CDC has tracked the health of more than 2,500 people with exposures to H5N1 virus-infected birds and this is the only case that has been found to date. Other people involved in the culling operation in Colorado have tested negative for H5 virus infection, but they are being retested out of an abundance of caution”
H5N1 viruses have been found in U.S. commercial and backyard birds in 29 states and in wild birds in 34 states since the CDC started monitoring for illness among people exposed to the viruses in late 2021.
Globally, this is the second human case associated with this specific group of H5 viruses, which are currently predominant, the CDC said. The first was reported in Britain in December 2021.
