Nevada confirms state's first human case of bird flu in a dairy worker | 10 Feb 2025 | 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. The H5N1 virus has reduced milk output in cattle and pushed up egg prices by wiping out millions of laying hens. The Nevada worker is recovering after suffering from conjunctivitis, or pink eye, the Central Nevada Health District said in a statement. The U.S. Department of Agriculture reported for the first time last week that a second strain of bird flu was found in dairy cattle in Nevada, a discovery that ramped up concerns about the U.S. outbreak.
