H5N1 Influenza

The H5N1 strain of highly pathogenic avian influenza (HPAI) is present in wild birds worldwide and is causing outbreaks in U.S. domestic birds and dairy cattle. Many other species are also susceptible to this virus. APHIS is working with our Federal, State, and industry partners to combat outbreaks, support producers, and strengthen prevention.

Detections of HPAI
The United States has the strongest avian influenza surveillance program in the world. APHIS monitors for the virus in commercial and backyard birds, wild birds, and dairy cattle. We also conduct confirmatory testing for HPAI in other domestic and wild animals. View the latest updates on detections of HPAI by species.
Outbreak Response and Support
USDA is investing $1 billion in a comprehensive strategy to curb HPAI, protect the U.S. poultry industry, and lower egg prices. This includes several producer support programs.
USDA offers financial assistance to help dairy producers enhance biosecurity and offset costs and losses from HPAI H5N1. This is in addition to our National Milk Testing Strategy and many other testing efforts and programs.
