lyme disease

Definition

Lyme disease is an infectious disease caused by at least three species of bacteria belonging to the genus Borrelia. Early symptoms may include fever, headache, and fatigue. A rash occurs in 70–80% of infected persons at the site of the tick bite after a delay of 3–30 days (average is about 7 days), and may or may not appear as the well-publicized bull's-eye (erythema migrans). The rash is only rarely painful or itchy, although it may be warm to the touch. Left untreated, later symptoms may involve the joints, heart, and central nervous system. In most cases, the infection and its symptoms are eliminated by antibiotics, especially if the illness is treated early. Delayed or inadequate treatment can lead to more serious symptoms, which can be disabling and difficult to treat.
