Lyme disease is a bacterial infection that is typically transmitted to humans through the bite of an infected blacklegged tick. Symptoms can include fever, headache, fatigue, and a characteristic rash, among other things. If you suspect that you or someone you know may have Lyme disease, it is important to seek medical attention from a healthcare professional.
