Roughly 10.3 million Ohio chickens have been impacted by bird flu in the last 30 days, making up more than a third of the national outbreak's recent victims as the disease continues to ravage livestock around the country.

The first case of bird flu in a human in Ohio has been reported, according to officials. A farm worker from Mercer County, Ohio, located on the state's western border along Indiana, came into contact with deceased poultry that was infected with the virus, the Ohio Department of Health announced on Wednesday.
