Traveller's Diarrhea
You take one vacation a year- don't let a case of traveller's diarrhea ruin your trip!
When you get diarrhea in Canada, the culprit is usually a virus.
When travellers develop diarrhea abroad, the most common causes are bacteria, typically related to inadequate hygiene on the part of the food vendor/traveller.
Some bacteria that cause stomach upset in travellers include Salmonella (which causes typhoid fever), Shigella, E.coli, Campylobacter and Cholera (very uncommon).
Typical strategies I recommend to minimize risk include getting vaccinated prior to your trip and being cautious about where you eat. I encourage travellers to bring along a treatment course of antibiotics to take only if they develop significant symptoms.
If you become ill with traveller's diarrhea:
drink clean water (bottled or boiled) or oral rehydration solution to stay hydrated
treat fever with fever reducers, such as tylenol (1g every 6 hours) or advil (400mg every 8 hours)
If you are not improving after 48 hours or you become very weak or feverish despite medications recommended above, I would encourage you to seek urgent medical care at your location.
The CDC has developed a free app called “Can I eat this?” -referring to this may help you if there is any ambiguity about food safety at your destination.

It is so easy to let your guard down when you are trying local street food or drinking tap water in unfamiliar regions, but a sudden bout of stomach trouble can easily cost you precious days of exploring scenic landscapes.
