Tick-borne illnesses rarely kill anyone, but they certainly cause their share of problems for kids who wander into wooded areas each summer season. Lyme Disease, one of the most common tick-borne illnesses, can cause fever, headache, fatigue, and a characteristic skin rash. If left untreated, it can spread to the heart and the nervous system, occasionally resulting in death. You can prevent Lyme Disease and other tick-borne illnesses by using insect repellent, checking for ticks and removing them promptly, applying pesticides, and removing underbrush from your property. But knowing your level of risk is a good start. If you live in Hawaii or New Mexico, Lyme Disease probably shouldn’t be among your greatest concerns. If you live in Pennsylvania or the New England states, however, we strongly suggest you double down on that repellent.
