Traveler's Diarrhea

  • Traveler should avoid:
    • Undercooked food except peeled fruits or vegetables
    • Fruit salads, chicken salads or lettuce
    • Non-bottled beverages and unpasteurized dairy products
    • Ice in drinks made from unfiltered/unbottled water source

Water Purification

  • Travelers who are going to be living in rustic circumstances overseas will need to make arrangements for a safe water supply

Prophylactic Antibiotics

  • Effective but cannot be recommended unless the complications of diarrhea in a traveler or severe dehydration in a person with an underlying medical condition cause the benefits of antibiotic prophylaxis to outweigh the risks
  • May also be given to asymptomatic people whose stools have been tested positive for Salmonella enterica subspecies enterica serovar typhimurium to reduce spread of infection


  • May decrease the incidence of diarrhea in travelers
  • Eg Lactobacillus sp, Saccharomyces boulardii, Bifidobacterium sp


  • V cholera is spread through contaminated food and water
  • Prevention depends on interruption of fecal-oral transmission
  • Travelers to regions with cholera should follow precautions for the prevention of traveler’s diarrhea
  • Water can be treated with Chlorine or Iodine, by filtration or by boiling


  • Drinking water can be treated with chlorine or iodine, by filtration or by boiling
  • Good hygiene by strict hand washing should be practiced
  • Proper food preparation and refrigeration may help prevent the spread of Shigella infection
  • Occurrence of Shigella infection in daycare or school should prompt diagnostic investigation (stool culture, PCR tests) of students and staff members, and isolation of infected students/personnel

Follow Up

  • Referral to an infectious disease specialist may be necessary in case of treatment failure
