Babesiosis; Human granulocytic anaplasmosis (HGA)
Lyme disease is caused by the bacterium Borrelia (B.) burgdorferi, which is transmitted through the bite of a deer tick. Either nymph or adult ticks can transmit B. Burgdorferi.
Most cases of Lyme disease can be prevented or cured with prompt antibiotic treatment following a deer tick bite. If a preventive antibiotic is needed, a single dose of doxycycline may suffice. To treat active disease, antibiotics are usually given for 2 - 4 weeks. Current guidelines do not recommend long-term antibiotic treatment for any stage or complication of Lyme disease.
