ABSTRACTThis paper reports the case of a 29-year-old female patient, who was originally from Mexico City and began her condition with pain in the second finger of left hand after a visit to the Aragon forest in Mexico City, progressing with nausea and diarrhea, as well as incapacitating arthralgias with predominance in hands and feet without erythema multiforme in hand. Upon admission, she had inflammation markers of 19 x 103/µL leukocytes and C-reactive protein of 28 mg/dL, which were elevated during her hospital stay; due to the lack of response to medical treatment and multiple negative tests, a Western Blot test for ricketsias was done obtaining a positive result for Borrelia burgdorferi, establishing the definitive diagnosis of Lyme borreliosis, receiving adequate treatment and presenting clear improvement. Lyme disease is a zoonosis transmitted by the ticks of the genus Ixodes caused by the spirochete Borrelia burgdorferi. Mexico City has not been reported as an endemic area, which is why we report this case.
