The Ohio Department of Agriculture (ODA) reported Feb. 2 that it has confirmed equine herpesvirus-1 (EHV-1) cases in four horses at separate locations around the state.

As such, the ODA has placed multiple facilities under quarantine and is actively investigating where these animals have been and what other animals might have been exposed.

The ODA confirmed that two of the positive horses raced at the Meadows Racetrack and Casino, in Washington, Pennsylvania. Those animals are currently under quarantine at separate facilities. One of the two raced at Miami Valley Gaming, near Lebanon, Ohio, on Jan. 13 and 24. Testing confirms they have EHV-1 but neither animal is showing clinical signs of illness.

“Racehorse owners should take immediate precautions to protect their animals,” said State Veterinarian Tony Forshey, DVM. “All owners should closely observe their horses for any signs of illness and take their temperatures daily. They should immediately contact their veterinarian if they have any concerns
