Thailand Health & Vaccinations Guide

Thailand has excellent healthcare facilities, especially in Bangkok, Chiang Mai, and Phuket, with modern private hospitals that rival those in Western countries. However, preparation is key to staying healthy. This guide covers recommended vaccinations, common health concerns, healthcare costs, and what to do if you get sick in Thailand. Most travelers have no health issues, but being informed helps you travel with confidence.

Recommended Vaccinations

Routine Vaccinations

Ensure your routine vaccinations are up to date: DTP (diphtheria, tetanus, pertussis/whooping cough), MMR (measles, mumps, rubella), and polio. In the Netherlands, these are part of the Rijksvaccinatieprogramma. Check with your huisarts or GGD if you are unsure about your vaccination status.

How to avoid: Visit your doctor or GGD travel clinic at least 6-8 weeks before departure for a vaccination consult.

Hepatitis A

Strongly recommended for all travelers to Thailand. Hepatitis A is transmitted through contaminated food and water. The vaccine consists of 2 doses (the second 6-12 months after the first) and provides protection for at least 25 years. A single dose provides protection for about 1 year.

How to avoid: Get vaccinated at least 2 weeks before departure for the first dose to be effective.

Hepatitis B

Recommended for travelers who may have sexual contact, get tattoos or piercings, or require medical treatment in Thailand. Transmitted through blood and bodily fluids. The standard vaccination is 3 doses over 6 months, but an accelerated schedule is available.

How to avoid: Many Dutch people born after 2011 received Hepatitis B vaccination as part of the national program. Check your vaccination booklet.

Typhoid

Recommended for travelers who will eat street food frequently or visit rural areas. Typhoid is spread through contaminated food and water. Available as a single injection (effective for 3 years) or oral capsules (effective for 1-3 years).

How to avoid: The injection is the most common choice - simple, one dose, and provides good protection.

Rabies

Consider if you plan to spend time in rural areas, around animals, or adventure travel. Thailand has stray dogs and monkeys that occasionally bite tourists. The preventive vaccination is 3 doses over 21-28 days. Note: even if vaccinated, you still need post-exposure treatment after an animal bite, but it is simpler and more readily available.

How to avoid: If bitten by an animal in Thailand, seek medical treatment immediately regardless of vaccination status. The Thai Red Cross in Bangkok is a leading rabies treatment center.

Japanese Encephalitis

Recommended for travelers staying longer than 1 month, especially in rural or agricultural areas. Transmitted by mosquitoes, primarily in rural areas near rice paddies and pig farms. The vaccine is 2 doses, 28 days apart.

How to avoid: Mainly a concern for extended rural stays. Most short-term tourists in cities and beach areas have very low risk.

Common Health Concerns

Traveler's Diarrhea

The most common health issue for tourists in Thailand. Usually caused by unfamiliar bacteria in food and water. Symptoms typically last 2-3 days. Stay hydrated with bottled water and rehydration salts (ORS), available at any pharmacy. Anti-diarrhea medication (loperamide/Imodium) provides symptom relief.

How to avoid: Drink only bottled or filtered water. Avoid ice from unknown sources (though most restaurants use factory ice which is safe). Eat at busy stalls where food turnover is high. Wash hands frequently.

Dengue Fever

Dengue is transmitted by Aedes mosquitoes that bite during the day, particularly around dawn and dusk. Symptoms include high fever, severe headache, joint and muscle pain, and rash. There is no specific treatment - only symptom management. Peak season is during and just after the rainy season (June-November).

How to avoid: Use insect repellent with DEET, especially during daytime. Wear long sleeves and pants at dawn and dusk. Stay in accommodation with screens or air conditioning. There is no vaccine widely available for travelers yet.

Sunburn & Heat-Related Illness

Many tourists underestimate the tropical sun. Severe sunburn, heat exhaustion, and heatstroke are common, especially in the first few days. The UV index in Thailand regularly reaches 11+ (extreme). The combination of heat and humidity makes dehydration a serious risk.

How to avoid: Apply SPF 50+ sunscreen every 2 hours. Wear a hat and sunglasses. Drink at least 2-3 liters of water daily. Take breaks in shade or air-conditioned spaces during peak sun hours (11 AM - 3 PM). Acclimatize gradually - do not plan strenuous activities for your first day.

Motorbike Injuries

The number one cause of serious tourist injuries and deaths in Thailand. Many tourists rent scooters without experience, proper licenses, or helmets. Thai roads can be chaotic, especially for those not used to driving on the left side. Many travel insurance policies do not cover motorbike accidents without a valid license.

How to avoid: Only ride if experienced and properly licensed (International Driving Permit). Always wear a helmet. Do not drink and drive. Check that your travel insurance covers motorbike accidents. Consider using Grab instead - it is cheap and safe.

Healthcare in Thailand

Private Hospitals

Thailand's private hospitals are world-class and a major medical tourism destination. Bumrungrad International Hospital (Bangkok), Bangkok Hospital Group, and Samitivej Hospital offer excellent English-speaking care with modern facilities. Costs are much lower than in Western countries but can still be significant without insurance.

How to avoid: Always have travel insurance that covers medical treatment. Keep the insurance company's emergency number accessible at all times.

Pharmacies

Thai pharmacies (look for green cross signs) are well-stocked and pharmacists can recommend over-the-counter medications for common ailments. Many medications that require a prescription in the Netherlands are available over the counter in Thailand, including antibiotics and some pain medications. Boots and Watsons are reliable pharmacy chains.

How to avoid: When buying medication, check the expiry date and ensure packaging is sealed. Ask the pharmacist about proper dosage.

Frequently Asked Questions

Do I need malaria tablets for Thailand?

For most tourists visiting popular destinations (Bangkok, Chiang Mai, Phuket, Krabi, Koh Samui, Pattaya), malaria prophylaxis is not necessary. Malaria risk exists mainly in remote border areas with Myanmar, Laos, and Cambodia. Consult with a travel health specialist (GGD in the Netherlands) based on your specific itinerary. Dengue prevention (insect repellent) is more important for most travelers.

Is the tap water safe to drink in Thailand?

No, do not drink tap water in Thailand. Always drink bottled water or filtered water. Bottled water is cheap (7-15 THB for 1.5 liters) and available everywhere. Ice in restaurants and bars is generally safe as it is produced commercially from purified water (you can tell by the cylindrical shape with a hole in the middle). Avoid ice made from tap water (irregular chunks).

How much does a hospital visit cost in Thailand?

At a private hospital, a basic consultation costs 500-1,500 THB ($15-45). Simple treatments (stitches, X-rays) range from 2,000-10,000 THB. Hospitalization can cost 10,000-50,000+ THB per day. Emergency surgery or serious injuries can quickly reach hundreds of thousands of THB. Travel insurance is essential - without it, you will need to pay upfront as hospitals require payment or insurance guarantee before treatment.

What should I do if I get bitten by a monkey or dog?

Immediately wash the wound thoroughly with soap and running water for at least 15 minutes - this is the most important first step. Apply antiseptic if available. Then go to the nearest hospital or clinic for rabies post-exposure treatment. Do not wait - rabies is almost always fatal once symptoms appear. Treatment is available throughout Thailand. If you were pre-vaccinated, you need only 2 booster doses. If not pre-vaccinated, you need 4-5 doses plus immunoglobulin.

Where can I get vaccinations in the Netherlands before my trip?

Visit a GGD travel health clinic (Reizigersadvies en Vaccinatiebureau). You can find the nearest one at ggdreisvaccinaties.nl. Make an appointment 6-8 weeks before departure. They provide personalized advice based on your destination, duration, and activities. Costs are typically 50-150 EUR for consultation plus vaccine costs. Some health insurance policies partially reimburse travel vaccinations.
