A mosquito-transmitted disease that usually is fatal to horses has been steadily increasing this year in South Carolina.
The Item newspaper reports that the state Veterinarian's Office has now verified 30 cases of Eastern equine encephalitis.
That's two times the number of cases found in South Carolina horses last year.
Sumter County was the first county where a horse tested positive for EEE this year and it now has three confirmed cases.
Health officials say about 90% of horses contracting the virus die from it. Fourteen died in our state last year.
Mosquitoes can spread the disease to humans.
No human cases have been reported in South Carolina so far this year, but one has been confirmed in Georgia and two in Florida.
Officials say the best way to combat EEE is to have horses properly vaccinated and try to minimize breeding grounds for mosquitoes on your property by frequently emptying items that might store standing water.
