Diarrhea Diseases from Travel

• Tropical diseases that cause diarrhea
• Includes cholera, typhoid and traveler's diarrhea
• Spread by food or drink made dirty with infected human waste
• Your child has no symptoms of tropical disease. If your child has symptoms, use other guides.
• Tropical diseases occur in people who travel to or live in high-risk countries. These mainly are developing countries near the Equator. You may have traveled to a high-risk country recently.

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.

Diarrhea Disease: How to Prevent

Safety Tips in All Countries:

• Hand washing is the key to prevent the spread of infections.
• Always wash the hands before eating, feeding or handling young children or cooking.
• Always wash the hands after any contact with vomit or stools.
• Wash the hands after using the toilet or changing diapers. Help young children wash their hands after using the toilet.

• Drink bottled water or boiled water. Avoid tap water, ice cubes and flavored ices.
• Eat foods that have been fully cooked and that are still hot.
• Dry foods such as bread are usually safe.
• Avoid salads and raw veggies. Avoid fruits that cannot be peeled. Bananas, oranges and apples are safe. Wash your hands before peeling fruit.
