Equine Herpesvirus Outbreak (EVH-1)

14 June 2011 No Comment

The equine herpesvirus myeloencephalopaty causes neurological signs appear as a result of damage to blood vessels in the brain and spinal chord. Almost all horses are infected with EVH-1 at a young age, but the virus generally becomes inactive. The virus can be reactivated during times of stress and transfered to other horses through direct contact or through objects (such as tack, water buckets, hands, ect). Symptoms of EVH-1 are fever, decreased coordination, urine dribbling, loss of tail tone, hind limb weakness, leaning for balance, lethargy, inability to get up.

Recently there has been an outbreak of the EVH-1 virus in eight western U.S. states that started at the National Cutting Horse Association Western National Championship in Utah.

Many eventing competitions have been cancelled due to the virus, including the Spring Gulch Horse Trials in Colorado and the Briar Fox Farm Spring Horse Trials in Kansas. Most competitions are taking extra health precautions to ensure competitors' safety, including more advanced health certificates and temperature checks.

Before you and your horse travel to a show, make sure you are aware of all the extra health precautions and restriction and always practice safe hygiene.
