Two other cases of HPAI have been reported in commercial poultry in the United States. One was in a commercial broiler flock in Fulton County, Kentucky, while the other was in a layer operation in New Castle County, Delaware.

So far in 2022, HPAI has been confirmed in three of North American flyways, with the Central Flyway being the only one to not have a confirmed case. However, the only case of HPAI to be confirmed in the Pacific Flyway did not involve commercial poultry. Instead, it was in a bald eagle in Vancouver, British Columbia, Canada. 

In accordance the international standards set by the World Organisation for Animal Health (OIE) wild bird findings, such as the eagle found in British Columbia, as well as backyard poultry and backyard non-poultry, should not result in any trade restrictions.
