The Illinois Department of Public Health says the horse was in LaSalle County and 11 people who came into contact with it have been given preventative treatment.
The last human case of rabies in Illinois was in 1954, but 50 bats have tested positive for the disease this year. The horse is the only animal other than bats to be diagnosed with rabies since 1998.
State veterinarian Connie Austin says Illinoisans should stay away from wild animals and vaccinate their pets.
The state's Natural Resources Department plans to test skunks in LaSalle, Lee and DeKalb Counties for the virus.
