Travellers' Diarrhea Prevention & Treatment

Travellers' diarrhea is the most common health problem affecting international travellers, particularly those visiting developing countries with poor sanitation. The condition is typically caused by enterotoxigenic Escherichia coli (ETEC), though other bacteria, viruses, and parasites can also be responsible. Symptoms appear 1–3 days after exposure and usually resolve within 3–5 days. While uncomfortable, travellers' diarrhea is not usually serious, but severe dehydration can occur. Prevention through careful food and water selection is the most effective strategy: drink only bottled or boiled water, avoid ice cubes, eat cooked foods, avoid raw fruits and vegetables (unless you can peel them yourself), and practice scrupulous hand hygiene.

At Peel Travel Clinic (905) 890-2757, we recommend preparing for travellers' diarrhea with a prevention and treatment kit. The kit may include oral rehydration salts, antidiarrheal medication (loperamide), and prescription standby antibiotics (usually a fluoroquinolone or azithromycin) to be used if symptoms develop despite preventive measures. Dukoral, our oral cholera vaccine, also provides cross-protective immunity against ETEC, making it an excellent option for travellers at high risk. Our physicians will counsel you on when and how to use these medications and when to seek medical attention.
