[heterophyiasis and diarrhea after travel: a case report of a child returning from a trip to egypt].the most frequently reported parasite-related diarrheal diseases in tropical travellers are amibiaisis, giardiasis, and certain types of nematoodiasis. intestinal distomiasis is uncommon because the parasite is strictly limited to certain areas of the world. however observation is possible as is demonstrated by this case report involving a 3-year-old child who presented diarrhea two weeks after returning from a six-week stay egypt. heterophyes heterophyes eggs were identified. this small fluke h ...19958559020
