Leptospirosis masquerading as infectious enteritis.

Leptospirosis is a zoonosis caused by a ubiquitous spirochete of the genus Leptospira and is endemic to the tropics. Prompt diagnosis and treatment are important in reducing the morbidity and mortality that can be associated with this illness. We report the case of a 30-year-old Israeli traveler who had returned from Thailand and developed fever, chills, vomiting and diarrhea. An unexpectedly high value of creatinine expanded the diagnostic possibilities beyond travelers' diarrhea. Leptospirosis was confirmed serologically and the traveler eventually recovered. Leptospirosis should be considered in the differential diagnosis of travelers returning with fever and gastrointestinal complaints.
