Due to the outbreak of EHV-1 (equine herpes virus) the Carbon County Fairgrounds along with most facilities in the state will be closed to all Horse Activities until at least June 1.
"Sorry for any inconvenience that this may cause, but until this has run its course your horse is safer at home," said Rhonda Peterson of the county Events Center and Fairgrounds.
The state veterinarian's office reports that as of Noon May 23 there were four quarantined facilities (Box Elder, Davis, Kane, and Utah counties) with a total of seven confirmed cases and eight suspect cases on these premises. Two of the cases were humanely euthanized after going down and unable to return to their feet.
The veterinarian notes that signs associated with this disease include fever, decreased coordination, nasal discharge, urine dribbling, loss of tail tone, hind limb weakness, leaning against a wall or fence to maintain balance, lethargy, and the inability to rise.
Horse owners should watch their horses carefully and call their veterinarian immediately if any abnormal signs are observed.
Horses that attended the Ogden event or have been in contact with horses that attended the event should be isolated and a minimum of two temperatures taken and recorded per day on each horse.
Notify your veterinarian of any temperature abnormalities or symptoms. If there is any increase in body temperature or abnormal clinical signs in any of your horses, notify your veterinarian immediately.
We are not recommending the cancellation of any events involving horses, mules, and/or burros at this time.
Utah has not changed its importation requirements for horses, mules, and/or burros entering the state.
There was only one horse euthanized at the Ogden event and the horse was diagnosed with a developmental
abnormality of the spine. Testing of the cerebrospinal fluid on this patient was negative for EHV-1 agent.
The equine herpesvirus, called EHV-1, disease is not transmissible to humans or other animals other than
equine (horses, mules, burros) or camelid (llamas, alpacas, camels) species.
The virus is contagious between camelids and horses and cannot be spread to other animals such as cats and
dogs. EHV-1 may cause only mild, flu-like illness in many cases, but some horses may become seriously ill with
respiratory or neurologic disease. EHV-1 may be fatal in some severely infected horses. The most common way for
EHV-1 to spread is by direct horse-to-horse contact. The virus also can spread through the air, contaminated
equipment, clothing and hands.
