![]() Although most tick bites are harmless, they must be removed quickly and safely to reduce the risk of infection. Symptoms range from headaches and fever to joint pain and lethargy. 12: 100–2.Lyme disease is a bacterial infection transmitted by the bite of a tick.

In the 1920s, French physicians Garin and Bujadoux described a patient with meningoencephalitis, painful sensory radiculitis, and erythema migrans following a tick bite, and they postulated the symptoms were due to a spirochetal infection. This rash was known as erythema chronicum migrans, the skin rash found in early-stage Lyme disease. Afzelius published his work 12 years later and speculated the rash came from the bite of an Ixodes tick, meningitic symptoms and signs in a number of cases and that both sexes were affected. In a 1909 meeting of the Swedish Society of Dermatology, Arvid Afzelius first presented research about an expanding, ring-like lesion he had observed. Treatment īoth Lyme disease and STARI can be treated with antibiotics, particularly doxycycline. Antibiotic treatment resolves the illness quickly. The associated infectious agent has not been determined. This erythema is also sometimes called erythema migrans or EM. Southern tick-associated rash illness (STARI) produces a similar rash pattern although it develops more quickly and is smaller. The rash may feel warm but usually is not itchy, is rarely tender or painful, and takes up to four weeks to resolve if untreated. In about 79% of cases in Europe but only 19% of cases in endemic areas of the U.S., the rash gradually clears from the center toward the edges, possibly forming a "bull's eye" pattern. ![]() The rash is usually circular or oval, red or bluish, and may have an elevated or darker center. The most distinctive features of the EM rash are the speed and extent to which it expands, respectively 2–3 cm per day and up to a diameter of 5–70 cm (50% attain more than 16 cm). The EM rash appears typically one or two weeks (range 3–32 days) after the bite. Most people who get infected do not remember seeing a tick or the bite. ![]() The initial sign of about 80% of Lyme infections is an erythema migrans (EM) rash at the site of a tick bite, often near skin folds, such as the armpit, groin, or back of knee, on the trunk, under clothing straps, or in children's hair, ear, or neck. After 8 weeks, the rash cleared from the center toward the edges and looked a bit more like a bull's eye. ![]()
