The first human case of bird flu linked to H5 occurred in Colorado, with the virus appearing in a person.
The person tested positive for avian influenza A(H5) virus, according to the CDC, and was involved in the culling of poultry suspected of having H5N1 bird flu. The episode, however, has no bearing on the CDC’s assessment of human risk to the general public, which is negligible.
This is the world’s second human instance linked to this particular category of H5 viruses. In December 2021, the first one was detected in the United Kingdom.
According to the CDC, the Colorado patient’s sole symptom was tiredness for a few days and he has now recovered. The patient was being treated with oseltamivir, an influenza antiviral medication, in isolation.
