Traveler's Diarrhea

What is traveler's diarrhea?

Diarrhea is the term for bowel movements that are loose or watery. Traveler's diarrhea occurs within 10 days of travel to an area with poor public hygiene. It’s the most common illness in travelers.

What causes traveler's diarrhea?

It’s caused by drinking water or eating food that has bacteria, viruses, or parasites. Most traveler's diarrhea is from bacteria. Diarrhea from viruses and parasites is less common. Food and water can be infected by people:

  • Not washing hands after using the bathroom
  • Storing food unsafely
  • Handling and preparing food unsafely
  • Not cleaning surfaces and utensils safely

Who is at risk for traveler's diarrhea?

You are at risk for this condition if you travel to a country that has poor public sanitation and hygiene. Poor hygiene in local restaurants is also a risk factor. Places that have the highest risk are often in developing countries in:

  • Africa
  • Asia
  • Central and South America
  • The Middle East

If you travel to a developing country, you are more likely to get this illness if you eat food or have drinks:

  • Bought on the street, such as from a food cart
  • In someone’s home
  • At lodging that provides all meals (all-inclusive)

You’re also at increased risk if you:

  • Take some kinds of ulcer medicine
  • Have had some kinds of gastrointestinal surgery

What are the symptoms of traveler's diarrhea?

The main symptom is loose stool that occurs suddenly. The stool may be watery. Other symptoms may include:

  • Nausea
  • Vomiting
  • Bloating
  • Belly (abdominal) pain or cramps
  • Blood in the stool
  • Trouble waiting to have a bowel movement (urgency)
  • Feeling tired
  • Fever

In most cases, symptoms last less than a week.

How is traveler's diarrhea diagnosed?

Your healthcare provider will ask about your health history and your symptoms. They will ask about your recent travel. You may also have a stool culture or other tests. A stool culture is done by taking a small sample of stool. It is then sent to a lab to check for bacteria, viruses, and parasites. If your symptoms last longer than 10 to 14 days, you may have other tests.

How is traveler's diarrhea treated?

Traveler's diarrhea often goes away in a few days. Often the only treatment is replacing fluids. You may be told to drink lots of fluids. These can include clear broth, flat soda, or juice. You may be given antibiotics or other medicines if your symptoms don’t get better. Combination treatment with an antibiotic and an antidiarrheal medicine may help you get better more quickly. Your healthcare provider may give these to you before you travel so you can take them at the first signs of traveler's diarrhea.

What are possible complications of traveler's diarrhea?

The loss of body fluid from diarrhea and vomiting can lead to dehydration. This can be serious. Contact your healthcare provider if you are not urinating as much as usual.

A small number of people can develop post-infectious irritable bowel syndrome. This can cause symptoms such as:

  • Long-term diarrhea
  • Belly pain and cramping
  • Bloating
