Laboratory findings for Borrelia miyamotoi disease (BMD), a new and emerging infection brought to the US by deer ticks, found 97 BMD cases identified by whole-blood polymerase chain reaction testing among 11,515 patients tested from the northeastern US. Clinical records were analyzed to identify the major features of acute disease. Patients with BMD presented with nonspecific symptoms, including fever, headache, chills, myalgia, and arthralgia. Other findings revealed:
• 24% of patients with BMD were hospitalized.
• Elevated liver enzyme levels, neutropenia and thrombocytopenia were common.
• 16% of patients with BMD were seropositive for IgG and/or IgM antibody to B. miyamotoi rGlpQ.
• 78% of patients with BMD has seropositive convalescent specimens.
