RESUMO

Human infection by Cyclospora cayetanensis, namely cyclosporiasis, can cause a wide range of symptoms in immunocompetent patients, from mild to severe diarrhea. Immunocompromised patients can present with chronic diarrhea and it has been recognized as a cause of traveler's diarrhea. We report three patients who traveled from Chile to Peru, who presented upon returning with prolonged traveler's diarrhea. A literature review about cyclosporiasis is presented, with emphasis on the clinical, epidemiological, diagnostic and therapeutic aspects of this disease.
