Bird Flu
Bird flu, or avian influenza, is a virus that is spreading through wild birds worldwide. It is causing outbreaks in poultry and U.S. dairy cows, and some human cases have been identified in people who have had close contact with infected dairy cows and poultry. In October 2024, CDPH identified the first cases of bird flu in humans from people working closely with infected dairy cattle.
While the current public health risk is low, CDPH is working with local, state and federal partners to monitor bird flu in farm animals and people who work closely with poultry and dairy cattle.
