The Ohio Department of Health has reported the state’s first probable human case of influenza A(H5), commonly known as highly pathogenic avian influenza (HPAI) or bird flu.
Health officials said the case involves an adult male farm worker from Mercer County who was in contact with deceased commercial poultry. The CDC considers the overall risk of bird flu to the general public to be low, though those with prolonged, unprotected exposure to infected birds face a higher risk.
Public Health Guidance
Officials advise that avoiding direct contact with wild birds, sick poultry, or dead animals is the best way to prevent infection. Anyone who encounters a sick or dead bird is urged to contact local health departments or veterinarians for guidance before handling them.
The Ohio Department of Agriculture (ODA) is urging poultry farm workers and commercial operators to take biosecurity measures to reduce the spread of avian flu, including:
- Preventing contact between domestic poultry and wild birds, especially migratory waterfowl.
- Minimizing farm visitors and ensuring anyone interacting with poultry follows strict sanitation protocols.
- Washing hands before and after handling birds, using soap and water or hand sanitizer.
- Using disposable boot covers or disinfectant footbaths when entering poultry facilities.
- Monitoring birds for signs of illness, such as swelling, labored breathing, or reduced egg production.
- Cleaning and disinfecting all equipment, tools, and vehicles before moving them between facilities.
Since the beginning of 2024, the U.S. has confirmed 68 human cases of HPAI across 11 states, including one fatality in Louisiana. Multiple cases have been linked to exposure in commercial agriculture operations or wild birds.
Ohio has reported cases of HPAI in poultry and dairy herds since the outbreak began in 2022. However, there have been no confirmed cases of human-to-human transmission of the virus, officials said.
"While the risk to Ohioans is low, the best way to prevent bird flu is to avoid unprotected exposures to sick or dead birds," said Ohio Department of Health Director Bruce Vanderhoff, MD, MBA.
Health experts say it remains safe to consume properly cooked poultry and pasteurized dairy products. The CDC recommends cooking poultry, eggs, and meat to their proper internal temperatures to eliminate bacteria and viruses.
