Avian influenza, also known as bird flu, is a highly pathogenic virus primarily affecting birds, particularly wild birds and domestic poultry such as chickens, ducks, and turkeys. While rare, human infections can occur in individuals with close, unprotected contact with infected animals or their bodily fluids. Symptoms in humans can range from mild upper respiratory issues to severe conditions like pneumonia or multi-organ failure. However, the virus does not currently spread from person to person.
Avian influenza has been detected in Maricopa County, with cases reported in a backyard poultry flock and zoo animals. No human infections have been reported, and the overall risk to the public remains low.
The Maricopa County Department of Public Health is working with federal, state, and local agencies to respond to the outbreaks.
On Dec. 11 the virus was confirmed in a small number of animals at Wildlife World Zoo in Litchfield Park. Following the confirmation, the zoo implemented immediate isolation and quarantine measures for affected animals and suspended guest activities involving direct animal contact. Enhanced biosecurity measures are also in place to prevent further spread.
