Equine Herpesvirus (EHV-1 or Rhinopneumonitis) infection in horses can cause respiratory disease, abortion in mares, neonatal foal death, and/or neurologic disease. The neurologic form of EHV-1 is called Equine Herpesvirus Myeloencephalopathy (EHM) and is a sporadic paralytic disease (myeloencephalopathy) secondary to vasculitis of the spinal cord and brain.

Abnormal hoof wear, inconsistent foot landing, hesitance in a portion of the stride, toe dragging, lack of hindlimb impulsion, stiff or bouncy canter, and imprecise stopping can all be seen with bilateral hindlimb lameness and certain diseases of the spinal cord such as "Wobbler" syndrome and EPM.

This serious disease, which attacks the horse's central nervous system, can be difficult to diagnose because its signs often mimic other health problems in the horse and signs can range from mild to severe. More than 50 percent of all U.S. horses have been exposed to the parasite that causes EPM.

Treating for 2 consecutive 28 day periods has been associated with an increase the effectiveness of the treatment and reduction in the likelihood of relapse. The addition of Sulfadiazine and Pyrimethamine (ReBalance) to the treatment has also been associated with an increase the effectiveness of the treatment and reduction in the likelihood of relapse.
