The highly pathogenic avian influenza (HPAI) situation in the United States is worsening, with new cases spreading in multiple regions including Iowa, Georgia, California, Ohio, Oregon, Minnesota, and South Dakota. The outbreak has led to the culling of millions of laying hens and the declaration of a state of emergency in some areas. The HPAI outbreak has also affected trade in poultry products, with temporary bans being imposed by countries like the Philippines.
