An outbreak of equine herpes virus-1 (EHV-1) has been confirmed at a private boarding stable in Lake County, Illinois.
Several horses in the stable are currently exhibiting neurologic signs consistent with those exhibited in EHV-1 infected horses, the Illinois Department of Agriculture said.
Horses stabled in the facility have been placed under quarantine by the state’s Bureau of Animal Health and Welfare. The quarantine will remain in place until it is determined that exposure to these horses no longer poses a risk to other horses.
No link has been established between the affected horses and any organized equine event.
State agriculture officials urged veterinarians to inform their clients about EHV-1 and measures to decrease the possibility of exposure.
Meanwhile, in Shelby County, Tennessee, a horse has tested positive for the neurologic form of the virus.
The Tennessee Department of Agriculture said one property had been quarantined.
The affected horse is under the care and observation of a veterinarian.
The cases do not at this stage appear to he linked to an outbreak in Florida, which has resulted in 10 properties being placed under quarantine.
