Overview
A rash similar to the rash of Lyme disease has been described in humans following bites of the lone star tick, Amblyomma americanum. The rash may be accompanied by fatigue, fever, headache, muscle and joint pains. This condition has been named southern tick-associated rash illness (STARI). The cause of STARI is not known.
Causes
The cause of STARI is unknown. Studies have shown that is not caused by Borrelia burgdorferi, the bacterium that causes Lyme disease. Another spirochete, Borrelia lonestari, was detected in the skin of one patient and the lone star tick that bit him. However, subsequent study of over two dozen STARI patients has found no evidence of B. lonestari infection.
STARI is specifically associated with bites of Amblyomma americanum, known commonly as the lone star tick.
Diagnosis
Laboratory Findings
STARI is diagnosed on the basis of symptoms, geographic location, and possibility of tick bite. Because the cause of STARI is unknown, no diagnostic blood tests have been developed.
Treatment
Medical Therapy
It is not known whether antibiotic treatment is necessary or beneficial for patients with STARI. Nevertheless, because STARI resembles early Lyme disease, physicians will often treat patients with oral antibiotics.
