Concurrent babesiosis and serological evidence of Lyme disease in a young patient.

Human babesiosis co-infected with Lyme disease in a young patient is an important condition. Here, we describe a case of a 39-year-old male patient with concurrent babesiosis and Lyme disease. Co-infections of tick borne diseases are often difficult to diagnose and underreported, and resulting in significant morbidity and mortality to patients. While co-infections have been infrequently described, it is of paramount importance that clinicians should be able to diagnose early and treat them effectively according to the patient geographical area and history of tick bite.
