Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of infected blacklegged ticks. Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans.

Treatment

A 2 – 4-week course of antibiotics is used to treat people who are diagnosed with Lyme disease. The specific antibiotic used depends on the stage of the disease and the symptoms.
