A case of H5N1 influenza infection detected in US dairy cows

A man in Texas has been diagnosed with H5N1 bird flu after close contact with infected dairy cows. This is the second confirmed case in the US, following the first case that appeared in Colorado in 2022. Preliminary analysis of the virus strain did not show any concerning mutations.

The US Centers for Disease Control and Prevention (CDC) stated that the infection does not change the assessment of the public health risk associated with H5N1 influenza in the United States. The risk of an outbreak here is still considered low. The patient is currently isolated and receiving treatment with antiviral drugs.

Avian flu can be transmitted to humans, but infections have only been reported in people who have had close contact with infected animals. However, the death rate of this flu strain is very high, up to 50% compared to 3% in regular flu cases. Current antibiotics are effective against circulating H5N1 influenza strains, and if the virus mutates to spread easily in humans, existing vaccines will also be effective in preventing it.
