RESUMEN
Initially described in travelers, outbreaks of cyclosporiasis were soon linked to imported food products. An outbreak of cyclosporiasis in Spanish travelers is described. After identification of Cyclospora cayetanensis in stool analyses, a specific questionnaire was completed. Pyrosis was described in 57% of cases (4/7). Peptic symptoms can be a useful clue to indicate the diagnosis of cyclosporiasis in patients with travelers' diarrhea.

BACKGROUND: Cyclosporiasis is a disease due to Cyclospora cayetanensis, an emerging coccidian parasite first described in 1979. It is an orally transmitted disease that is more frequent in tropical and subtropical areas. Cyclospora cayetanensis has been mainly described as a cause of travelers' diarrhea. This pathogen has given rise to a number of epidemic outbreaks attributable to ingestion of imported foods, particularly from tropical areas. METHODS: Descriptive study of clinical and epidemiological data of a small epidemic outbreak of C cayetanensis-induced gastroenteritis. RESULTS: Seven confirmed cases of C cayetanensis among Spanish nationals who had traveled to Antigua Guatemala are described. The incubation period was 6 days. Diarrhea, asthenia, anorexia, borborygmi, flatulence, and abdominal distension were present in all cases. Fever and heart burn in 85.7%. Weight loss in 71.4%. Abdominal pain, rectal tenesmus, and nausea in 42.8%. Vomiting and eructation in 14.2%. Heart burn was a frequent symptom, a finding not often previously described. The infection was probably acquired from raspberry juice. All cases improved with trimethoprim/sulphametoxazol. CONCLUSIONS: Cyclosporiasis is a cause of travelers' diarrhea. Parasitology laboratories must be advised of clinical suspicion of cyclosporiasis so that they can conduct a suitable targeted study; otherwise, false negative results may arise.
