ALERT! Sixth Case of EEE Reported in NC
by Claire Holley on 8/3/2016

The NC Department of Agriculture has received laboratory reports confirming the sixth positive case of Eastern Equine Encephalitis (EEE) for 2016 in North Carolina.  The case is located in:

Onslow County – Three (3) year-old female Quarter Horse.  The animal was unvaccinated.        

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. “And if your horses aren’t vaccinated, talk to your veterinarian about vaccinating all of your equine as soon as possible against EEE and West Nile Virus.”  The vaccinations initially require two shots, 30 days apart, for horses, mules and donkeys that have no prior vaccination history. Meckes recommends a booster shot every six months in North Carolina because of the state’s prolonged mosquito season.
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.
