EHD Kills 2,000 Deer
More than 2,000 deer are dead due to a virus spread by gnats.
Epizootic hemorrhagic disease, or EHD, causes deer to have high fevers and severe internal bleeding. They die from the virus after a day or two.
The worst outbreaks are in the hottest and driest years, like this one.
Experts said hunters in Illinois will not have to worry about the virus.
"This disease will be over as soon as we have the first good hard frost, because, since it's spread by these tiny little insects, they'll be gone as soon as that happens," Paul Shelton of the Department of Natural Resources said.
The disease is not life-threatening to humans.
Most infected deer have been found in Cook, Calhoun, Coles, Macon, and Shelby counties.
Other animals, including elk mule deer, antelope, and bighorn sheep, are also vulnerable.
