As things remain tense between Canada and the United States, many Canadian travellers are rethinking vacation plans to US destinations and looking to other warm-weather destinations instead. But different destinations come with different health risks, warns Dr. Wayne Ghesquiere, an infectious and travel disease expert, who helps vacationers prepare for and limit risks of travel-related illness.
The rising risk of travel-related illnesses in popular destinations
Each year, millions of Canadians travel to South America, the Caribbean, and Southeast Asia. Many are unaware of the higher risks of contracting common mosquito-borne diseases, like chikungunya and dengue fever or food and water-borne illnesses, like traveller’s diarrhea, which can be mild to severe, even life-threatening in extreme cases.
Chikungunya may not be as familiar to vacationers, but it causes high fevers in adults and severe, often debilitating, joint pain that can last for weeks, months or even years. Chikungunya has been reported in 110 countries and is found in warm regions, including the Caribbean, Central America, South America, and Asia.
“Thankfully, there are ways to reduce your risk of infection,” said Dr. Ghesquiere. “Wear light-coloured, long-sleeved clothing and use insect repellent. Also consider a new Health Canada-approved vaccine that can be taken four weeks before travelling.”

Many assume diarrhea during travel is just an unfortunate part of vacation—but it doesn’t have to be.
Surprisingly, many travellers put themselves at risk of illness within the first three days by eating uncooked foods like salads and fresh salsa, brushing their teeth with tap water or drinking freshly-squeezed juice with ice cubes.
“I recommend preparing before you go and considering your options,” said Dr. Ghesquiere. “While no prevention measure can eliminate all risks, vaccines provide an added layer of protection, like Dukoral, a drinkable vaccine that helps prevent cholera and diarrhea during travel caused by LT producing enterotoxigenic E.coli, the most common cause of diarrhea during travel in many parts of the world. It’s taken at least two weeks before travel and provides added protection so you can focus on enjoying your vacation – not the nearest bathroom.”
Dr. Ghesquiere also recommends travellers be careful about food choices, opt for bottled water and wash hands regularly with soap and water. Rehydration measures must be taken in case of diarrhea.
If you have upcoming travel plans, speak to your doctor, pharmacist, or book a consultation with a travel clinic 4 to 6 weeks before departure to receive medication and vaccination recommendations specific to you, your health and your destination. It’s the best way to have a safe and enjoyable trip.
