Planning a trip to Thailand is exciting — but making sure you're properly protected health-wise is an important step that many travellers leave too late. The good news is that Thailand is generally a very safe destination health-wise for tourists, and most vaccinations needed are routine ones you may already have. Here's everything you need to know about staying healthy in Thailand in 2026.
Recommended Vaccinations for Thailand
| Vaccine | Recommendation | Why |
|---|---|---|
| Hepatitis A | Strongly Recommended | Spread through contaminated food and water — very common risk for travellers |
| Typhoid | Strongly Recommended | Spread through food and water, especially street food |
| Tetanus/Diphtheria | Recommended | Make sure your routine boosters are up to date |
| Hepatitis B | Recommended | Spread through blood and bodily fluids — worth having |
| Rabies | Consider | If visiting rural areas, trekking or working with animals |
| Japanese Encephalitis | Consider | If spending time in rural areas during rainy season |
| COVID-19 | Recommended | Keep up to date with current recommendations |
Do I Need Malaria Tablets for Thailand?
This is one of the most common questions about Thailand health. The answer depends on where you're going. Bangkok, Phuket, Koh Samui, Chiang Mai city and most popular tourist areas have virtually no malaria risk and tablets are not needed.
Malaria prevention medication is only recommended if you're travelling to very remote rural border areas — particularly near the borders with Myanmar and Cambodia. For the vast majority of tourists visiting popular Thai destinations, malaria tablets are not necessary.
Food and Water Safety in Thailand
Water: Do not drink tap water in Thailand — stick to sealed bottled water which is widely available and very cheap ($0.30–$0.50 per litre). This also applies to ice in drinks — most reputable restaurants and hotels use filtered ice but be cautious at street stalls.
Food: Thai street food is generally very safe — high turnover means food is freshly cooked. The golden rule is to eat where locals eat and choose food that's cooked fresh in front of you. Avoid pre-cooked food sitting out in the heat for long periods.
Traveller's diarrhoea is the most common health issue for visitors to Thailand. Pack oral rehydration salts and consider carrying a course of antibiotics prescribed by your doctor before travel.
Essential Health Items to Pack for Thailand
| Item | Why |

| Oral rehydration salts | For traveller's diarrhoea recovery |
| Sunscreen SPF 50+ | Thai sun is very strong year round |
| Antihistamines | Insect bites and allergic reactions |
| Antiseptic cream | Minor cuts and scrapes |
| Travel insurance documents | Absolutely essential — always have cover |
Travel Insurance for Thailand
Travel insurance is absolutely essential for Thailand. Healthcare costs for serious illness or injury can be very high at international hospitals. Make sure your policy covers medical evacuation and that you have the emergency number saved on your phone before you travel.
