Lyme Disease
Lyme disease is an infection transmitted through the bite of an infected blacklegged tick. The majority of human cases occur as a result of exposure to areas known to have infected blacklegged ticks. Early symptoms may include fever, headache, muscle and joint pain, fatigue and an expanding red rash. The best prevention is to avoid tick bites by using insect repellent, wearing proper clothing, removing ticks as soon as possible after bites and removing tick habitats from around the home.
