The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service recently announced the presence of highly pathogenic avian influenza (HPAI) in non-commercial backyard flocks (non-poultry) in Linn County, Oregon, and in Pacific County, Washington.

And on May 4, 2022, the presence of HPAI was confirmed in a great horned owl in Wichita County, the first such confirmed case in a wild bird in Texas. 

“It spreads so widely because it can be carried asymptomatically in migratory waterfowl,” explained Timothy McDermott, an extension educator in agriculture natural resources for Ohio State University, reported Modern Farmer on May 9, 2022.

The virus can be carried asymptomatically, McDermott says, but as birds migrate along their common pathways, they come into contact with birds traveling in opposite directions.

For instance, the Atlantic and the Mississippi flyways converge in Ohio, which could easily turn into a bird super-spreader gathering spot at the Lake Erie Basin.

As of May 7, 2022, 34 states have confirmed HPAI outbreaks leading to the depopulation of about 37.5 million birds this year.

Avian influenza is caused by an influenza type A virus that can infect chickens, turkeys, pheasants, quail, domestic ducks, geese, and guinea fowl and is carried by free-flying waterfowl such as ducks, geese, and shorebirds. 

According to the U.S. CDC, the public health risk associated with these avian influenza detections in birds remains low. 

While the U.S. FDA-approved flu shots do not protect people from a bird-flu infection, there is one pandemic influenza vaccine (Audenz) already stockpiled by the U.S. government.
