The top 15 destinations abroad for Canadian travellers demonstrate a widely varying risk of contracting the most common travel-related illness, Travellers’ Diarrhea (TD), but analysis of the statistics reveal that over 2 million Canadian travellers may have suffered its effects in 2016. Although you might be surprised by the figures, here’s how you can help avoid this illness from contaminated drinking water in foreign destinations.

Perhaps unsurprisingly, figures from Statistics Canada show that the United States was by far the predominant destination for Canadians, with more than twice as many of them travelling there than the next 14 top ranking destinations combined.

By utilizing the above statistics it is possible to make estimates for the potential incidence of contracting travellers’ diarrhea, as well as how this might be impacting trips. Using the common categorization of countries into “high”, “intermediate” or “low” risk for acquiring TD, the map and table above can be easily converted into the one below:

With these destinations and traveller numbers in place it is relatively easy to calculate the potential incidence of travellers’ diarrhea:

It is also possible to calculate the potential impacts of travellers’ diarrhea on travellers:

Whether you are going for business, leisure or any other reason, we recommend that for overseas travel destinations you take extra care to stay properly hydrated and avoid drinking water directly from all outdoor sources (e.g. rivers, lakes, streams, wells), municipal water supplies (taps), and suspect ‘fake’ or counterfeit bottled water.

An aquapure traveller™ will

• Help you to avoid dangerous dehydration by allowing use of any water source* whenever you need to drink

• Protect you from harmful microbiological pathogens (bacteria, viruses, cysts) and many chemical  contaminants (heavy metals, pesticides, organic industrial pollutants) in drinking water

• Save you money while producing up to 350 litres of clean, safe drinking water from contaminated sources, with no waiting time, chemicals or batteries

• Avoid the need to purchase single-use drinking water bottles which end up littering our land and polluting our oceans

The top 15 destinations for Canadian outbound travellers and the number of visits made in 2016 comes from  Statistics Canada.
The categorization of countries by TD risk was taken from the  Government of Canada, the  U.K. NICE (including the percentage of risk by zone), and the U.S. CDC,  With regard the overall risk it is noted that the U.S. CDC advises that “Attack rates range from 30% to 70%”. We have used the more conservative U.K. figures of 0% to 7% for low risk, 8% to 20% for intermediate risk, and 20% to 60% noted  here, with a median figure of 3.5%, 14% and 40% respectively. 
For the ‘impact percentages’ we have again utilized figures from TravelHealthPro (itself referencing Ericsson CD. Travelers’ diarrhea. Epidemiology, prevention, and self-treatment. Infect Dis Clin North Am 1998; 12: 285–303 cited in Al-Abri, S.S. Beeching, N.J. Nye F.J. Traveller’s diarrhoea. Lancet Infect Dis. 2005 Jun; 5 (6):349-60).
