LOUISIANA DEPARTMENT OF AGRICULTURE: Horses Test Positive for Eastern Equine Encephalitis and West Nile Virus

Louisiana Department of Agriculture issued the following announcement on Aug. 19.

Sixteen horses have tested positive for Eastern Equine Encephalitis (EEE) and one has tested positive for West Nile Virus (WNV) since June 5, 2019. Department of Agriculture and Forestry Commissioner Mike Strain, D.V.M., is reminding horse owners to vaccinate their animals for both EEE and WNV.

“It’s been a wet season and we are seeing an unusually high number of cases at this time,” said Strain. Horses are infected the same way humans are infected – by being bitten by infected mosquitoes – so everyone needs to take extra precautionary measures at this time.”

If a mosquito bites an infected bird, EEE or WNV can be spread to horses, dogs, cats and humans. These mosquito-transmitted diseases can cause inflammation or swelling of the brain and spinal cord.

Clinical signs can include: fever, loss of appetite, weakness and loss of coordination.

The disease can often result in death.

EEE primarily causes disease in the equine species such as horses, mules, donkeys and zebras. However, a number of other animals such as pigs, llamas, bats, reptiles, amphibians, and rodents can also be infected.

WNV primarily affects birds, but can also infect bats, horses, cats, dogs, chipmunks, skunks, squirrels, domestic rabbits, alligators and humans.

Prevention includes removing standing water where mosquitos breed and using mosquito repellants that are safe for animals and humans. Horses can also be vaccinated. So far, there is no vaccination approved for people. Horse owners should contact their local veterinarian regarding proper vaccination protocols during this time of increased risk.

Veterinarians are required to call the Louisiana Department of Agriculture and Forestry if they suspect EEE or WNV in a horse as they are reportable diseases.
