How can I stay healthy while traveling in Thailand?
Thailand is one of the easiest places to travel in Asia when it comes to health, but that doesn’t mean you can throw caution to the wind. From mosquito bites to street food surprises, here’s how to stay in top shape during your trip.
Pharmacies and medical care
Forget stuffing your bag with meds — Thai pharmacies (raan khai yaa) are well-stocked and affordable. Many pharmacists speak English and can help with minor illnesses. If you need something familiar, Boots pharmacies (yes, the UK chain) have branches in major cities.
If things take a turn for the worse, hospitals in Bangkok and provincial capitals are excellent. Some even cater to medical tourists. If you have a serious health issue, you may want to head to the capital or even fly home — check that your travel insurance covers medical evacuation.
Vaccinations and preventative care
There are no required vaccines for Thailand, but doctors recommend:
- Tetanus and diphtheria — Because stepping on rusty nails isn’t fun.
- Hepatitis A and B — Easily spread through food, water, or bodily fluids.
- Typhoid — Recommended if you’ll be eating a lot of street food.
- Rabies — If you’ll be hiking, visiting rural areas, or just can’t resist petting stray dogs.
Malaria? It’s only a concern in remote jungle areas near the borders with Cambodia, Laos, and Myanmar. If you’re staying in cities, islands, or tourist hotspots, you don’t need anti-malarial tablets.
Mosquito-borne illnesses
Mosquitoes in Thailand carry more than just malaria — in fact, dengue fever and chikungunya are bigger threats. These viruses have no vaccine or cure, so your best defense is not getting bitten.
- Use DEET-based mosquito repellent and reapply often.
- Wear long sleeves and pants at dawn and dusk.
- Stay in air-conditioned rooms or use mosquito nets.
- Use plug-in mosquito repellers or coils at night.
Dengue fever feels like the worst flu of your life — high fever, intense body aches (hence the nickname “breakbone fever”), and exhaustion. If you develop symptoms, get to a doctor fast.
Food and water safety
Thai food is amazing, but stomach problems are common. To avoid food poisoning:
- Drink bottled or filtered water (tap water isn’t safe).
- Eat at busy food stalls — high turnover means fresh food.
- Avoid ice in drinks unless you’re sure it’s made from purified water.
- Wash your hands or carry hand sanitizer before meals.
If you get traveler’s diarrhea, drink oral rehydration salts (ORS) and stick to bland foods like rice and bananas. Avoid anti-diarrheal meds unless absolutely necessary — they can make infections last longer.
Wildlife hazards
Jellyfish and sea creatures
Thailand’s waters aren’t always paradise. Jellyfish — sometimes deadly ones — appear after storms. If stung:
- Rinse with salt water and vinegar (not fresh water).
- Remove tentacles with a gloved hand or credit card.
- Seek medical help if symptoms worsen.
Stray dogs, monkeys and rabies
Rabies is a real risk in Thailand, mainly from dogs, cats, and monkeys. Even a lick on broken skin can transmit it. If bitten or scratched:
- Wash the wound immediately with soap and disinfectant.
- Go to a hospital for post-exposure shots — don’t wait for symptoms.
- Avoid feeding monkeys — they can be aggressive.
Leeches and sandflies
Jungle trekking? Leeches love you. They’re not dangerous, just annoying. Burn them off with a lighter or sprinkle salt to make them drop.
Sandflies leave itchy, allergic reactions — locals swear by coconut oil as a repellent.
Stomach troubles and digestive issues
Digestive issues are the most common travel problem. If you get hit with a bad case:
- Drink lots of water to avoid dehydration.
- Take ORS (oral rehydration salts) — you’ll find these at any Thai pharmacy.
- Stick to plain food until you recover (rice, toast, bananas).
Anti-diarrheal meds like Imodium are useful for long bus rides, but they only mask symptoms. If diarrhea lasts more than a week or includes blood or fever, see a doctor.
HIV and STDs
Thailand’s sex industry is a reality, and HIV rates remain high. If you engage, use condoms (sold everywhere, including convenience stores). Blood transfusions in Thai hospitals are safe due to strict screening.
