Lyme Disease

Lyme disease is a bacterial infection caused by Borrelia burgdorferi, transmitted to humans through the bite of infected black-legged ticks (commonly called deer ticks). Symptoms often include fever, fatigue, headache, and a distinctive bullseye-shaped skin rash called erythema migrans. If not treated early with antibiotics, the infection can spread to joints, the nervous system, and the heart, leading to more serious complications.
