Illinois says a virus outbreak has claimed more than 400 deer this year and has spread to 49 counties, including Schuyler, Greene, Macoupin, Cass and Sangamon counties in west-central Illinois. While most of the deaths of white-tailed deer from Epizootic Hemorrhagic Disease have been in Peoria, Lawrence and Fulton counties, the numbers as of this week were significant in Schuyler, Menard and Macoupin counties in the region. The Illinois Department of Natural Resources has received reports of 432 suspected cases of the disease so far this year. While the disease is not hazardous to humans or pets, it has been shown to affect livestock, prompting the state to caution producers to be vigilant.Epizootic Hemorrhagic Disease is a viral disease of white-tailed deer that can cause localized die-offs when conditions are favorable for transmission. Infected animals develop a high fever, and dead animals often are found near water sources. Hunters may encounter deer killed by the disease when they go into the woods during the fall deer hunting seasons.
