A strain of H5N1 avian influenza has been detected in wild and domestic birds in many parts of the U.S., and has been identified in Washington State. For more information on the current activity across the country, please see USDA’s 2022 Detections of Highly Pathogenic Avian Influenza and CDC’s Bird Flu Current Situation Summary. Public health officials are working closely with local, state, and federal partners to monitor bird flu in Washington.
How does avian influenza spread from birds to people?
Birds infected with avian influenza shed the virus in their saliva, mucous and feces. People can become infected if the virus gets into a person’s eyes, nose or mouth or if it is breathed in. Bird flu infections in people are rare and most commonly occur after prolonged contact with infected birds while not wearing appropriate personal protective equipment.
Should you be concerned?
- Although avian influenza is a highly contagious disease among birds, the risk of it spreading to people is very low.
- The current strain of H5N1 avian influenza circulating in other parts of the country is different than strains that caused H5N1 outbreaks in previous years. To-date, the current H5N1 strain circulating in birds does not appear to easily infect people.
- Two human cases with the currently circulating H5N1 strain have been reported worldwide, with one case reported in the UK and one case reported in Colorado. Both case patients had significant contact with infected birds prior to detection of H5N1 virus. The UK resident did not develop any symptoms of illness and the Colorado resident reported fatigue.
- As a precautionary measure, people who have had known contact with infected birds will be contacted by public health to discuss risk and symptom monitoring.
