Frequently Asked Questions
What vaccines do I need for Thailand?
For Thailand, the following vaccines are recommended: Hepatitis A (all travelers), Typhoid (all travelers, especially for street food), Hepatitis B (most travelers), Tdap (if not current), and Rabies (for adventure travelers, those visiting rural areas, or anyone with likely animal contact — Thailand has significant rabies risk from dogs and monkeys). Japanese Encephalitis is recommended for travelers staying longer than 1 month or visiting rural areas during monsoon season.
Is malaria a risk in Thailand?
Malaria risk in Thailand is primarily limited to forested border regions with Myanmar (Burma), Cambodia, and Malaysia — particularly in provinces like Tak, Kanchanaburi, Trat, and Narathiwat. Bangkok, Chiang Mai city, Phuket, Koh Samui, and most popular tourist destinations have no significant malaria risk. If you are trekking near the Myanmar or Cambodia border, discuss malaria prophylaxis with our travel medicine physician.
Is dengue fever a risk in Thailand?
Yes — dengue fever is present throughout Thailand including Bangkok, Chiang Mai, and tourist islands like Phuket and Koh Samui. It is transmitted by daytime-biting Aedes mosquitoes. There is no approved dengue vaccine for first-time visitors in Canada. Prevention relies on using DEET-based repellents (30%), wearing long clothing, and avoiding outdoor exposure at dawn and dusk when mosquito activity peaks.
Do I need a visa or vaccinations to enter Thailand?
Canadian passport holders can enter Thailand visa-free for up to 60 days (as of 2025). There are no mandatory vaccine requirements for entry from Canada. However, Hepatitis A, Typhoid, and rabies vaccines are strongly recommended. Yellow fever vaccination is required only if arriving from a yellow fever endemic country within the preceding 6 days.
Is it safe to eat street food in Thailand?
Thailand has excellent street food culture, and with the right precautions, it can be enjoyed safely. Ensure you are vaccinated for Hepatitis A and Typhoid before travel. Choose busy stalls with high turnover, eat food that is freshly cooked in front of you, and avoid raw salads washed in tap water or ice from unknown sources. Travellers' diarrhea is still possible — our physician can prescribe a standby antibiotic for self-treatment.
