What exactly is traveler’s diarrhea?

Traveler’s diarrhea is a stomach and intestinal infection that occurs as a result of eating or drinking contaminated food or water that has been handled in an unsanitary manner. intestinal bugs in stomachContrary to popular belief, contaminated food, not water, is the primary cause of this illness. One of the most common ways of being affected is by cooks and food handlers who don’t wash their hands after they’ve used the bathroom, thus spreading bacteria to unknowing patrons. Another frequent cause is when vegetables and fruits are chopped on the same surface as raw meat.

Almost 80% of all cases of traveler’s diarrhea are caused by E. coli bacteria, while only 20% are caused by other types of bacteria, which can include Salmonella, Shigella, and Campylobacter, parasites, and viruses.

The symptoms of traveler’s diarrhea can vary. However, abdominal cramps, bloating, nausea, vomiting, fever, and at least three unformed stools in a 24-hour period are the typical signs of infection.

What can you do to avoid getting travel’s diarrhea?

Keep Your Hands Clean

  • Wash your hands with soap and water often, especially before eating and after using the bathroom.

  • Carry and use pre-packaged hand wipes or hand sanitizer with an alcohol base of at least 60%, which will decrease the likelihood of the bacteria’s spread.
  • As a general rule, keep your hands away from your mouth.

    Watch What You Eat

    • Choose foods that are cooked and served hot, avoid food that’s been sitting around in a buffet.
    • Eat raw fruits and vegetables only if you’ve washed them with clean water or if you’ve peeled them.
    • Avoid dairy, and uncooked meat or seafood.
    • Avoid purchasing food from street vendors.
    • Choose a popular restaurant when you go out to eat. Usually, if a restaurant is crowded the food isn’t left sitting around for long.

    Watch What You Drink 

    • Avoid drinking tap water.
    • Drink bottled water and beverages from factory-sealed containers. Check the seals to verify that they haven’t been tampered with. Sometimes water bottles are simply refilled from the tap.

    • Avoid ice cubes or frozen drinks. Since the water source is unknown, try to keep away from them even while drinking alcoholic beverages. Keep in mind that alcohol isn’t strong enough to kill parasites, viruses, and bacteria, and they are not destroyed by freezing.
    • Use bottled water to mix baby formula, or buy sealed premixed formula.
    • Order your coffee or tea steaming hot, not tepid.
    • Boil tap water or milk if you don’t have access to bottled water or sealed pasteurized milk.

    Other Measures

    Remember that you can still get traveler’s diarrhea from tap water, even without drinking it. That’s why it’s important to brush your teeth with bottled water and keep your mouth closed while showering. Also, remember to check if natural bodies of water are safe before you go swimming.

    Oh no! What to do now?

    If you already have the first signs of diarrhea, that means you will be constantly losing fluids and electrolytes. Make sure you have access to clean water and that you keep yourself well hydrated. Regularly check the colour of your urine for signs of dehydration. The darker it gets, the less hydrated you are.

Unlike other types of anti-diarrheal medication, Fowler’s won’t block your digestive system or upset the beneficial bacteria in your bowels.

    Finally, if you notice blood in your stool or have a high fever, these are signs of a severe infection and you should make sure to see a doctor as soon as possible. Taking these precautions and knowing what to do in case traveler’s diarrhea strikes can make all the difference in the world and help you make sure you’ll truly enjoy your trip.
