Borrelia miyamotoi

Borrelia miyamotoi is a rare, but emerging tickborne disease similar to tickborne relapsing fever transmitted by the blacklegged tick. The incubation period is unknown but may range from days to weeks. Symptoms commonly reported include fever, chills, fatigue, severe headache, joint pain and muscle pain. Less common symptoms include dizziness, confusion, vertigo, rash, shortness of breath, nausea, abdominal pain, diarrhea, and lack of appetite. To date, there are no comprehensive studies to evaluate treatment regimens, but in published case series, patients were successfully treated with antibiotics and dosages used for Lyme disease. To prevent Borrelia miyamotoi, it is important to avoid tick bites. Examples of prevention measures includes avoiding wooded areas with dense shrubs and leaf litter, wearing protective clothing, using insect repellents, performing tick checks and by mowing lawns and keeping shrubs trimmed.
