Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted through the bite of infected blacklegged ticks. The most common symptoms of Lyme disease include fatigue, fever, headache, and a distinctive skin rash called erythema migrans. Left untreated, later symptoms can involve the joints, heart, and nervous system. https://www.zupyak.com/p/4363940/t/lyme-disease-treatment-understanding-your-options
