• A medical consultation is automatically recommended for children under two years of age, pregnant women, the elderly or those suffering from a chronic disease.

• Similarly, medical advice is required at any age in life, in moderate or severe forms, with fever and mucus-bloody stools.

• It is also advisable to consult in the absence of improvement within 48 hours or in case of aggravation. Indeed, we cannot blame all digestive disorders on traveler’s diarrhea. If the symptoms worsen, if there are more than 20 stools per day, or if new signs appear such as jaundice, discolored stools with brown urine, severe abdominal pain or a fever of 40 ° C, it could be something quite different: indeed, nothing looks more like a turista than a cholera or viral hepatitis in their early stages. As for late diarrhea (often after returning from a trip to a tropical zone), with abdominal pain or blood in the urine, they require a medical consultation. They can, for example, come from bilharzia due to the presence of a parasite in the intestines or in the urinary tract, contracted during swimming in infested water: a single-dose treatment is enough to overcome them, but still it is necessary to know that one reached. It can also be linked to an amoebiasis.
