The avian influenza appears to be winding down across the United States, following a precipitous drop off in reported cases since April. So far, zero commercial flocks and just seven backyard flocks have reported cases in July. 

Since the outbreak began in January 2022, more than 40 million birds across 201 counties have been killed, either by the virus itself or intentionally culled to prevent further spread of the highly pathogenic disease. Table egg layers, or domesticated chickens grown primarily to produce eggs for human consumption, represent 30 million of the total affected population.

Other affected groups include commercial chickens, turkeys, and ducks grown for meat sale, breeders, gamebirds, hobbyists’ flocks, petting zoo birds, and wild birds.
