RALEIGH – North Carolina horse owners are urged to vaccinate their equine after two horses in Horry County, South Carolina contracted Eastern Equine Encephalomyelitis within the past three weeks. EEE is a mosquito-borne disease that is preventable in equine by vaccination. Horry County is the northern-most coastal county in South Carolina and borders Brunswick County in North Carolina.
EEE causes inflammation or swelling of the brain and spinal cord and is usually fatal. Symptoms include impaired vision, aimless wandering, head pressing, circling, inability to swallow, irregular staggering gait, paralysis, convulsions and death. Once a horse has been bitten by an infected mosquito, it may take three to 10 days for signs of the disease to appear.
“If your horses exhibit any symptoms of EEE, contact your veterinarian immediately,” said State Veterinarian Doug Meckes.
Meckes recommends that equine owners talk to their veterinarians about an effective vaccination protocol to protect horses from EEE and another mosquito-borne disease, West Nile virus. The combo vaccination initially requires two shots, 30 days apart, for horses, mules and donkeys that have no prior vaccination history. Meckes recommends a booster shot every six months.
Mosquitoes can breed in any puddle that lasts for more than four days, so removing any source of standing water can reduce the chance of exposing animals to WNV or EEE. Keeping horses in stalls at night, using insect screens and fans and turning off lights after dusk can also help reduce exposure to mosquitoes. Insect repellants can be effective if used according to manufacturers’ instructions.
People, horses and birds can become infected from a bite by a mosquito carrying the diseases, but there is no evidence that horses can transmit the viruses to other horses, birds or people through direct contact.
