The rise in tick activity poses health risks to residents of Northern Illinois, particularly from the Lone Star Tick, which can transmit the Heartland Virus. Symptoms of the virus include fever, fatigue, and joint pain, and some cases require hospitalization. Additionally, the Lone Star Tick can trigger a rare allergy to meat and dairy products. With no available vaccine or treatment, the public is urged to take preventive measures to avoid tick bites. The increase in tick-borne illnesses highlights the need for awareness and caution during outdoor activities.
