About Avian Flu
Highly pathogenic avian influenza has been detected on commercial farms in California and other parts of the United States. The most recent outbreak of the highly transmissible strain of bird flu began in early 2022 and has resulted in the deaths of millions of chickens and turkeys. It has also been detected in cows in the U.S., marine mammals in South America, and other species globally. The CDC has confirmed a handful of human cases in the U.S. and several cases of avian flu in cats on dairy farms. Visit CDC for the current situation summary.
