Nevada has confirmed its first human case of bird flu in a farm worker who was exposed to infected dairy cattle, the Central Nevada Health District said on Monday, after authorities last week reported a second strain of the virus in cows in the state.

Nevada just confirmed its first human case of avian flu from infected cattle. Nevada’s first case was found in Churchill County, the Central Nevada Health District announced on Monday. The infected person — who showed signs of conjunctivitis but had no other symptoms — is recovering.

Federal health officials say a dairy worker in Nevada has been infected with a new type of bird flu that’s different from the version that has been spreading in U.S. herds since last year.

Six dairy herds in Nevada have tested positive for a newer variant of the H5N1 bird flu virus that’s been associated with severe infections in humans, according to the Nevada Department of Agriculture.

A new variant of the H5N1 bird flu — the same one that led to the death of a Louisiana man — has for first the first time been found in infected U.S. dairy cattle.

Nevada confirms its first human case of bird flu amid a growing U.S. outbreak impacting poultry, wildlife and the price of eggs.
