What is traveler’s diarrhea?

This diarrhea is caused by a bad critter called Enterotoxigenic E. coli.

How do you acquire the bacteria?

If you drink water or food contaminated with feces from someone that had the pathogen.

Where does it attack?

It goes directly to the small intestine and will associate with the epithelial cells in which it will liberate two types of toxins to enter the cell and once inside it will make the cell expel its fluids. The symptoms start a few hours after exposure and last a few days.


  • Watery diarrhea
  • Dehydration
  • Nausea
  • Vomiting

There are not many medicines to relief this but to drink a lot of water, since you small intestine cells are releasing them!!!

Be careful always in where the food and water you drink comes from, remember this will affect your quality time and health after all.

Traveler’s diarrhea (TD) is a stomach and intestinal infection. TD is defined as the passage of unformed stool (one or more by some definitions, three or more by others) while traveling.[2][3] It may be accompanied by abdominal cramps, nausea, fever, and bloating.[3] Occasionally bloody diarrhea may occur.[5] Most travelers recover within four days with little or no treatment.[3] About 10% of people may have symptoms for a week.[3]

Bacteria are responsible for more than half of cases.[3] The bacteria enterotoxigenic Escherichia coli (ETEC) are typically the most common except in Southeast Asia, where Campylobacter is more prominent.[2][3]About 10% to 20% of cases are due to norovirus.[3] Protozoa such as Giardia may cause longer term disease.[3] The risk is greatest in the first two weeks of travel and among young adults.[2] People affected are more often from the developed world.[2]
