The first known case of H5 bird flu in human has been confirmed by the United States Centre for Disease Control and Prevention (CDC) in the Western state of Colorado.
In a statement the CDC stated that the person who tested positive for avian influenza A (H5) virus was involved in the culling of poultry presumed to have had H5N1 bird flu.
It was said that the patient reported fatigue for a few days as the only symptom and had since recovered.
CDC asserted that the patient is being isolated and treated with the influenza antiviral drug oseltamivir.
“This case does not change the human risk assessment for the general public, which CDC considers to be low,” the agency said.
CDC had been monitoring for illness among people exposed to H5N1 virus-infected birds since these outbreaks were detected in U.S. wild birds and poultry in late 2021.
H5N1 viruses have been found in U.S. commercial and backyard birds in 29 states and in wild birds in 34 states, according to the CDC.
The agency has tracked the health of more than 2,500 people with exposure to H5N1 virus-infected birds and this is the only human case that has been found to date.
It is the second human case worldwide associated with this specific group of H5 viruses that are currently predominant.
The first case was reported in Britain in December 2021.
