A Case Report of Babesiosis Seen Outside of its Endemic Area and Incubation Period

Babesia microti is a parasitic alveolate that is usually transmitted by Ixodes scapularis tick, which also transmits Lyme disease. Babesiosis is endemic in the Northeast and Upper Midwestern regions of the United States. This case report illustrates a 29-year-old Hispanic male who presented to a Florida hospital emergency department with complaints of fever, generalized weakness, and flu-like symptoms over a duration of four days. Subsequently, he was diagnosed with babesiosis infection since he had a travel history to Cape Cod, Massachusetts about 10 weeks before presenting to the hospital. He was treated with atovaquone, clindamycin, and azithromycin. The importance of this report is to illustrate that babesiosis may occur outside its endemic area and incubation period.
