Are you planning a trip to an exotic country and dreading traveler 's diarrhea, a condition that affects nearly one in three travelers? Also known as turista , this illness can quickly turn your dream vacation into a nightmare. Knowing its symptoms and how to react will allow you to travel with peace of mind and fully enjoy your trip.
What is traveler's diarrhea?
Traveler's diarrhea, also known as turista, is an acute gastroenteritis that occurs when traveling to a country with hygiene standards different from what you are used to. This illness most often affects travelers who visit tropical or subtropical destinations , particularly in Latin America, Africa, the Middle East, and Southeast Asia.
Traveler's diarrhea occurs after ingesting water or food contaminated with bacteria, viruses, or parasites . Your digestive system, unaccustomed to these pathogens, reacts with intestinal inflammation. In approximately 30% of cases, enterotoxigenic Escherichia coli is the causative agent, according to StatPearls.
Traveler's diarrhea is generally mild and resolves favorably without specific treatment in most cases. However, medical attention may be necessary to limit the risk of complications in children and the elderly .
What are the symptoms of traveler's diarrhea?
Traveler's diarrhea typically appears suddenly in the first few days after your arrival . Recognizing the symptoms quickly will allow you to react in time!
Common digestive symptoms
The characteristic symptom of traveler's diarrhea is watery diarrhea , as confirmed by a review published in the Journal of Travel Medicine. Specifically, you will have at least three loose bowel movements per day , or even more.
Abdominal cramps are another common sign of this illness. These stomach pains are often accompanied by an unpleasant feeling of bloating . You may experience nausea, sometimes followed by vomiting. This combination of diarrhea and vomiting increases the risk of dehydration .
Associated general signs
Beyond digestive problems, traveler's diarrhea also manifests itself through other symptoms reported directly by some travelers in a prospective study :
- a moderate fever (between 38 and 39 °C)
- significant fatigue
- muscle pain
- the presence of blood and/or mucus in the stool
Excessive fluid loss during illness can cause dehydration . Certain signs can alert you:
- intense thirst, dry mouth and lips
- darker and less abundant urine
- Headaches, dizziness and confusion (severe forms)
If you notice blood in your stool and a fever above 39°C, contact a general practitioner for an urgent medical consultation .
Evolution and duration of symptoms
Symptoms of traveler's diarrhea usually appear between 6 and 72 hours after exposure to the infectious agent. The acute phase lasts between 3 and 5 days, during which time the symptoms are most intense.
Starting on the third day, bowel movements usually become less frequent and abdominal pain gradually subsides. Most travelers recover completely within a week without specific treatment.
However, in approximately 10% of cases , symptoms may persist beyond two weeks. In such cases, a consultation is necessary to obtain an accurate diagnosis.
What are the causes of traveler's diarrhea?
According to a review published in Travel Medicine and Infectious Disease , traveler's diarrhea is caused by bacterial agents in 80% to 90% of cases , with enterotoxigenic Escherichia coli being the main culprit. Other bacteria are frequently implicated, including Campylobacter , Salmonella , and Shigella .
Viruses are the second most common cause of traveler's diarrhea, particularly norovirus and rotavirus. Less frequently, parasitic agents such as Giardia lamblia or Entamoeba histolytica can also cause this illness.
The mode of transmission is almost exclusively fecal-oral : you contract the disease by ingesting contaminated food or drinks. Aside from your age and physical condition, your food choices during travel increase the risk of contracting this disease. The main sources of contamination are unpeeled fruit, raw vegetables , unfiltered tap water, ice cubes, and undercooked food .
How to relieve the symptoms of traveler's diarrhea?
Immediate measures
Rehydration is the first-line treatment . You must drink plenty of fluids to compensate for the loss of water and minerals. Ideally, opt for oral rehydration solutions ( ORS ) or sports drinks containing electrolytes. You can prepare a homemade solution by mixing six teaspoons of sugar and half a teaspoon of salt in a one-liter bottle of drinking water.
Temporarily avoid dairy products , fatty, spicy, or high-fiber foods. Opt for a light diet : white rice, bananas, applesauce, and crackers. Rest is essential to allow your immune system to effectively fight the infection.
Possible medications
According to a report published by a group of experts in the Journal of Travel Medicine, loperamide is an antidiarrheal medication that reduces bowel movement frequency. It should only be used in the absence of high fever or blood in the stool.
Antiemetics help control persistent nausea and vomiting. These medications can improve your comfort during the acute phase .
Antibiotics are not necessary for simple traveler's diarrhea. They should only be considered in cases of severe diarrhea with high fever or persistent symptoms. In such cases, the doctor may prescribe rifaximin or other treatments depending on the circumstances.
You can also use digestive protectants such as diosmectite , which protects the intestinal lining and relieves abdominal pain. Consult your pharmacist for personalized advice.
Note: Prolonged self-medication is not recommended. Consult a healthcare professional if symptoms last more than 48 to 72 hours, if there is a high fever, if there is blood in the stool, or if the patient is a child, elderly, or ill.
Natural remedies
To soothe your intestines during illness , you can consume probiotics (plain yogurt, kefir, fermented cheeses, kimchi or other fermented foods), ginger for nausea and peppermint tea to soothe abdominal cramps.
Prevention: how to avoid traveler's diarrhea?
Prevention relies on rigorous hygiene and strict food precautions . The golden rule: Boil it, cook it, peel it, or forget it . This motto sums up the health advice to follow when you travel.
When travelling in high-risk areas:
- Consume only bottled water with a sealed cap or water that has been previously boiled.
- Avoid ice cubes and drinks served in glasses rinsed with tap water.
- Also use bottled water to brush your teeth.
- Opt for well-cooked foods served hot.
- Avoid raw vegetables, unpeeled fruit, seafood, unpasteurized dairy products, reheated dishes, and street food.
Hand hygiene is your best defense against illness. Wash your hands thoroughly with soap before every meal and after using the toilet. Carry hand sanitizer for situations where soap and water are not available.
Depending on the country you are visiting, vaccination against typhoid fever may be recommended, as can be found on the French National Health Insurance (Ameli) website . Consult your doctor before departure and prepare a suitable first-aid kit.
Traveler's diarrhea and possible complications
Traveler's diarrhea can lead to complications requiring medical attention .
The main risk is severe dehydration , particularly in infants, young children, the elderly and those with weakened immune systems .
Traveler's diarrhea can also progress to an invasive form . Certain bacteria, such as Salmonella, Shigella, or Campylobacter, can, in rare cases, cross the intestinal wall and enter the bloodstream, leading to a serious infection. As reported in a case study , a healthy 30-year-old man developed non-typhoidal Salmonella bacteremia after traveling in Asia.
After an episode of traveler's diarrhea , approximately 10% of travelers develop post-infectious irritable bowel syndrome (PI-IBS) , according to some studies. This functional disorder manifests as chronic digestive symptoms, such as abdominal pain , bloating, or alternating diarrhea and constipation , which can persist for several months.
