The first human case of H5 bird flu in the United States has been identified in a resident of Colorado, according to the Centers for Disease Control and Prevention (CDC).
According to the CDC, the individual tested positive for avian influenza A(H5) virus and was engaged in the culling of chickens suspected of having H5N1 bird flu.
“This instance does not alter the CDC’s low risk assessment for the general public,” the agency noted.
The patient first presented with exhaustion and has since recovered, according to the CDC, which added that the patient was isolated and treated with the influenza antiviral medicine oseltamivir.
Since the CDC began monitoring for disease among individuals exposed to the viruses in late 2021, H5N1 viruses have been detected in commercial and domestic birds in 29 states and in wild birds in 34 states.
“The CDC has followed the health of over 2,500 humans who have been exposed to H5N1 virus-infected birds, and this is the sole case to yet. Other individuals participating in the Colorado culling operation have tested negative for the H5 virus, but are being retested out of an excess of caution “According to the CDC.
This is the second human case worldwide related with this particular strain of H5 viruses, which are now dominating, according to the CDC. The first was reported in December 2021 in the United Kingdom.
