Borrelia miyamotoi Infection in Patients from Upper Midwestern United States, 2014–2015

Abstract

We confirmed Borrelia miyamotoi infection in 7 patients who had contracted an illness while near La Crosse, Wisconsin, USA, an area where Ixodes scapularis ticks are endemic. B. miyamatoi infection should now be considered among differential diagnoses for patients from the midwestern United States who have signs and symptoms suggestive of tickborne illness.
