The Animal and Plant Health Inspection Service (APHIS) confirmed highly pathogenic avian influenza (HPAI) in a commercial flock in the United States on February 8, 2022. Since then, efforts have been made to identify, respond to detections, and mitigate the impact on U.S. poultry production and trade. Detections of HPAI are more common in the fall and spring due to wild birds spreading the virus as they migrate. APHIS collaborates with state animal health officials to conduct surveillance in commercial, backyard, and wild birds. Bird owners are advised to practice biosecurity measures to prevent the spread of the virus. The U.S. poultry flock comprises over 378.5 million egg-laying chickens, with more than 9.4 billion broiler chickens and 218 million turkeys processed in 2023. A dashboard provides real-time data on confirmed HPAI cases, reflecting the current impact on U.S. birds as the virus levels fluctuate based on wild bird movements.
