Idaho state officials say two horses were euthanized after showing neurological symptoms consistent with equine herpesvirus (EHV-1). Both horses were located in Bonneville County.
The Idaho State Department of Agriculture says one of the horses tested positive for the neurologic strain of EHV-1.
EHV-1 is highly contagious among horses, but poses no threat to humans. It causes respiratory disease, abortion, and intermittent outbreaks of neurologic disease in horses. Symptoms that should alert horse owners to the possibility of neurologic EHV-1 include fever, weakness, incoordination, and urine dribbling or inability to urinate.
Horses with these symptoms should be examined immediately by a veterinarian. Suspect horses should be isolated from healthy horses.
Deputy State Veterinarian Dr. Scott Leibsle recommends horse owners use preventative biosecurity measures while transporting or boarding horses at facilities that have regular traffic on and off the grounds.
· Limit horse-to-horse contact.
· Limit horse-to-human-to-horse contact.
· Avoid use of communal water sources.
· Avoid sharing of equipment unless thoroughly cleaned and disinfected between uses.
· Monitor your horse for clinical signs of disease and report any temperature over 102°F to a veterinarian.
“I encourage owners to contact their veterinarian immediately if and when they observe any symptoms of illness in their horses,” said Dr. Leibsle.
EHV-1 is a Notifiable Disease in Idaho.
