A tick-borne disease so new it only has a scientific name has been identified in United States patients for the first time, including at least one person from Nantucket. Borrelia miyamotoi is a relative of Lyme disease with similar symptoms including fever, headache, muscle ache, and fatigue.
Unlike Lyme disease, B. miyamotoi presents recurring fevers in patients and does not trigger a bulls-eye rash. Nor does it cause a positive test with traditional Lyme disease testing, said Dr. Sam R. Telford 3rd, a professor of infectious diseases at Tufts University.
