Wisconsin officials confirm a second horse has tested positive for the non-neuropathogenic strain of the equine herpesvirus (EHV-1.) The health of the horse, located in St. Croix County, is improving.
A Polk County equine is also recovering after tests confirmed it has EHV-1.
A third horse in Burnett County was euthanized last month. Tests came back negative for EHV-1, according to the state veterinarian.
Minnesota officials are awaiting test results after a horse in Isanti County began showing neurologic symptoms and was unable to urinate. To date, positive cases have been confirmed in Minnesota, Wisconsin, Iowa, and Colorado.
EHV-1 must be reported in the state of Wisconsin to state officials.
Veterinarians recommend that horses with a fever and symptoms of contagious respiratory infection should be kept at home and not taken to shows, competitions, clinics or public trail rides. Horse owners should also be aware that transportation of horses to competitions, shows and clinics may increase the risk of exposure to infectious organisms.
