SPRINGFIELD - As hunting season opens, the Illinois Department of Public Health (IDPH) wants to remind hunters to take precautions against tick bites to prevent contracting diseases they may carry, like Lyme disease. Other tickborne diseases include Rocky Mountain Spotted Fever, Tularemia, Ehrlichiosis, and Babesiosis. While most tickborne infections are reported during the summer, ticks are still active when temperatures are above freezing.
