PRCA Livestock Welfare News Animal Health Alert

May 16, 2011
The PRCA is closely monitoring the issues surrounding the outbreak of Equine Herpes Virus (EHV-1) that has spread through the Western United States.   At this time we do not have any confirmation of any States that have restricted the transportation of horses, nor have any PRCA rodeos been cancelled at this time due to this outbreak.  We will continue to monitor the situation and share information via www.prorodeo.com,

social media as well as these updates.  Please contact Cindy Schonholtz at 719-440-7255 or animalwelfare@prorodeo.com with any questions or concerns.


Information about the Outbreak: 
You can read all of the details below but basically 2 horses in CO tested positive for the virus
after attending the National Cutting Horse Association event in Ogden, Utah from April 30 to May 8.   Since the diagnosis of the CO horses, horses in several other states including Idaho, California and Washington were diagnosed - they also were at the Utah show.  Horses at a cutting horse show in Kern County, CA came down with the virus at the show.  One of those horses and horses in several other states have been euthanized do to the disease.  

Information on the disease:  
The EHV-1 organism spreads quickly from horse to horse and the neurologic form of the virus can reach high morbidity and mortality rates. The incubation period of EHV-1 is typically 2-10 days. 

Prognosis depends on severity of signs and the period of recumbency. There is no specific treatment for EHV-1. Treatment may include intravenous fluids, anti-inflammatory drugs and other appropriate supportive treatment. Currently, there is no equine vaccine that has a label claim for protection against the neurological strain of the virus.


Advice for Horse Owners: 
All horse owners who attended the Ogden, UT, event should notify their veterinarian and isolate and monitor their horses for clinical signs of the disease. Some horses may not show signs of the disease but may still be a carrier. Those owners are also encouraged to restrict movement of their horses and take the horses temperature 2 times daily, even if they show no other symptoms if the temperature is elevated contact your veterinarian immediately. 
Every horse owner should educate themselves on the symptoms and if their horse show any symptoms, ISOLATE, DO NOT MOVE THEM and CONTACT YOUR VETERINARIAN IMMEDIATELY.   

Symptoms include: 
Fever preceding neurologic signs (either in a horse diagnosed with EHM or in horses that
have been exposed to a horse diagnosed with EHM),
Decreased coordination,
Urine dribbling,
Loss of tail tone,
Hind limb weakness,
Leaning against a wall or fence to maintain balance,
Lethargy, and
Inability to rise.
