How Tropical Diarrhea Diseases are Detected by this Symptom Checker

• These diseases can't be diagnosed over the phone. But, they can be suspected based on their symptoms. They are then referred to a medical setting where a diagnosis can be made.
• Cholera will be picked up by the Diarrhea or Vomiting guides. Diarrhea that lasts too long or is severe will refer the child to be seen. Dehydration is a health problem where the body has lost too much fluid. It can be a result of diarrhea and/or vomiting. This will also be picked up in these guides.
• Typhoid will be picked up by the Diarrhea guide. Diarrhea that lasts too long or is severe will refer the child to be seen. Bloody stools or fever lasting too long also refer the child to be seen.
• Traveler's diarrhea will be picked up by the Diarrhea or Vomiting guides. Diarrhea that lasts too long or is severe will refer the child to be seen. Dehydration will also refer the child to be seen.
• Travel to a high risk country should raise the concern. However, common diseases such as viral diarrhea also must be ruled out. They occur more commonly in these countries than the serious diseases. But, severe symptoms or symptoms that last too long make us think about these other diseases.
