Staying Healthy in Thailand

Staying Healthy in Thailand: A Practical Guide for Expats

Thailand is a wonderful country to live in or visit, but staying healthy requires some awareness and preparation – especially for newcomers. The good news is that Thailand has excellent healthcare infrastructure, particularly in Bangkok and major cities. With a few sensible precautions, most expatriates live healthy, active lives here for years.

Food and Water Safety

Thai street food is generally safe and absolutely delicious – but some common-sense rules will keep you healthy:

• Drink bottled or filtered water: Tap water in Thailand is not safe to drink directly. Bottled water is inexpensive and available everywhere. Most restaurants serve filtered water.
• Eat hot, freshly cooked food: Street food cooked to order in front of you is usually safe. Avoid food that has been sitting out for hours, especially in heat.
• Wash fruit and vegetables: Peel fruit yourself or wash it thoroughly. Raw vegetables at tourist-oriented restaurants may have been washed in tap water.
• Be cautious with ice: Ice made from purified water (cylindrical ice with a hole in the middle) is generally safe. Crushed ice of unknown origin is riskier.
• Spicy food adjustment: If you are not used to chilli, ease into Thai food gradually. Even mild Thai dishes can be intensely spiced by Western standards.

Tropical Diseases and Vaccinations

Before arriving in Thailand, consult a travel doctor about the following vaccinations and preventive measures:

Recommended Vaccinations

• Hepatitis A and B
• Typhoid (especially if eating street food)
• Japanese Encephalitis (for long-term residents, especially in rural areas)
• Rabies (for those who may have contact with animals)
• Tetanus and Diphtheria (standard booster)

Malaria

Malaria risk in Thailand is primarily in forested border regions with Myanmar, Cambodia, and Malaysia. Most cities, tourist areas, and Korat/Isaan are considered low or no risk. If you are trekking in remote border areas, take prophylaxis medication and use DEET-based insect repellent. For more information on trekking in Southeast Asia, see our article on trekking in Nepal as a comparative experience.

Dengue Fever

Dengue is endemic throughout Thailand and is the most common tropical infection affecting expats. Unlike malaria, there is no widely available prophylaxis – prevention is entirely through avoiding mosquito bites. Use repellent, wear long sleeves at dawn and dusk, and ensure accommodation has window screens. Symptoms include sudden high fever, severe headache, joint pain, and a skin rash. See a doctor immediately if suspected.

Heat and Sun

Thailand is hot year-round. Heat exhaustion and sunstroke are real risks, particularly for new arrivals. Stay hydrated, avoid strenuous outdoor activity during peak midday heat, use sunscreen (SPF 50+), and wear a hat. Acclimatise gradually – especially if you arrive during hot season (March–May).

Thailand’s Healthcare System

Public Hospitals

Thailand has a network of government hospitals (โรงพยาบาลรัฐ) that are affordable but often crowded. Quality ranges widely. Emergency care at major government hospitals (such as Maharat Nakhon Ratchasima Hospital in Korat) is generally good.

Private Hospitals

For expats and those with health insurance, private hospitals in Thailand offer excellent care at a fraction of the cost of private healthcare in Western countries. Major private hospital groups include Bangkok Hospital, Bumrungrad International, Samitivej, and local provincial private hospitals. In Korat, Bangkok Hospital Korat is highly regarded.

Health Insurance

Comprehensive health insurance is strongly recommended for all expats in Thailand. Consider:

• International health insurance (Cigna, Aetna, Allianz) for full coverage including medical evacuation
• Thai Social Security – if employed by a Thai company, Thai Social Security provides basic healthcare cover at designated hospitals
• 30-baht scheme (Gold Card) – for Thai nationals and permanent residents only

Mental Health and Lifestyle

Expatriate life, while rewarding, can also bring challenges: cultural isolation, language barriers, and the disruption of moving country. Take care of your mental health by:

• Building a social network (expat groups, community organisations, language exchanges)
• Maintaining regular exercise – Thailand has excellent gyms, cycling routes, and outdoor sports facilities
• Learning basic Thai – even a few phrases significantly reduces daily stress and opens doors
• Keeping in contact with family and friends back home
