Thailand is a popular travel destination, but it's important to take precautions to ensure your trip is trouble-free and that you don't bring home any diseases. Here is some information on required and recommended vaccines for Thailand travel:

Required Vaccines:

According to the CDC, there are no mandatory vaccines for entry into Thailand. However, a yellow fever vaccination certificate is required for travellers aged 9 months or over arriving from countries with a risk of yellow fever transmission.

Recommended Vaccines:

  • Japanese Encephalitis: Recommended for travellers who will be in the country for an extended period, frequent travellers, and those travelling to rural areas. Japanese Encephalitis is spread through mosquito bites, and the risk is highest for long-stay travellers to rural areas.
  • Rabies: Thailand is considered a high-risk country for rabies. The vaccine is recommended for long-term travellers and those who may come into contact with animals.
  • Hepatitis A: Recommended for most travellers, especially those who will be consuming food and water in the country. Hepatitis A is spread through contaminated food, water, and close contact.
  • Typhoid: Recommended for travellers, especially those who plan to eat food from places with poor sanitation, such as markets or street stalls.
  • Chikungunya: Thailand is a higher-risk region for this mosquito-borne virus. Vaccination is recommended, especially for older travellers and those with underlying medical conditions.
  • Hepatitis B: Recommended for travellers to most regions, especially those at higher risk of infection, including drug users, men who have sex with men, and patients with kidney failure.
  • Influenza: Recommended for all travellers, especially as Thailand's rainy season can increase the risk of respiratory illness.
  • COVID-19: Recommended for travel to all regions, both foreign and domestic.

In addition to these vaccines, travellers should ensure that their routine vaccinations are up to date, including Measles, Mumps, Rubella (MMR), Chickenpox, and Tdap (Tetanus, Diphtheria, and Pertussis). Older adults or those with certain medical conditions may also want to consider vaccinations for shingles and pneumonia.

How to prepare for bug bites

Thailand's tropical climate makes it a welcoming environment for insects. Mosquitoes, in particular, can carry dengue fever, a serious illness that kills thousands every year in Thailand. Other diseases spread by mosquitoes have killed more people than all the world wars and natural disasters combined.

  • Dress appropriately by wearing long-sleeved shirts, long pants, and hats. This will help cover your skin and reduce the risk of mosquito bites.
  • Use insect repellent containing DEET on exposed skin. This will help protect you from mosquito bites.
  • Sleep under a mosquito net, preferably one treated with permethrin, an insecticide.
  • Choose accommodation with screens and fans. Screens will help keep mosquitoes out, while fans can help circulate air and reduce the number of mosquitoes in the room.
  • Treat clothing with permethrin, especially if you plan to spend time in high-risk areas. Permethrin is an insecticide that can be applied to clothing and gear to kill or repel insects.
  • Avoid stagnant bodies of water, dense jungles, and mangrove swamps, as these areas tend to have a higher concentration of insects.
  • Stay in well-maintained hotels and guesthouses to reduce the risk of bed bugs. Bed bugs are small insects that can live in mattresses and furniture and feed on human blood.
  • Be cautious around stray dogs or other animals that may carry fleas or ticks.
  • Be aware of rove beetles, which can cause an itchy, reddish rash called paederus dermatitis.
  • If you are trekking in the jungle, especially during early morning or evening when insects are most active, pack a powerful insect repellent with DEET and reapply regularly.
  • If you are sleeping in bungalows or other exposed areas, ensure that mosquito netting is in place to protect you from bites.
  • Be mindful of your surroundings and avoid touching or disturbing insects.
  • If you are bitten by an insect, avoid scratching the area. Clean the bite and apply hydrocortisone cream or calamine lotion to reduce itching.
  • For more serious reactions, such as an allergic reaction, seek medical attention.

Food and water safety

  • Eat fully cooked foods and avoid raw seafood: Opt for food that has been cooked in front of you, and avoid dishes that have been left out in the open.
  • Choose reputable dining places: Look for vendors with long lines, as this usually indicates satisfied recurring customers. Prioritise stalls with local Thais in the queue over those with only tourists.
  • Drink bottled beverages: Avoid drinking tap water. Instead, opt for bottled water or beverages.
  • Be cautious with ice: Avoid ice in drinks unless it is in large, uniform pieces with a hole through it, indicating that it was made from filtered water.
  • Practise good hand hygiene: Wash your hands frequently, especially before eating, to reduce the risk of getting sick.
  • Be wary of street food in unsanitary areas: Use your best judgement when it comes to street food. Observe the vendor's workstation and food handling practices before making a purchase.
  • Avoid undercooked shellfish: Along with vaccination, maintaining proper hygiene and avoiding undercooked shellfish are essential for preventing Hepatitis A infection.
  • Be cautious with fruit and vegetables: It is generally safe to bathe and wash fruit and vegetables with tap water in Thailand. However, avoid consuming raw produce that cannot be peeled, as it may have been washed with tap water.

Preventing and treating animal bites

While travelling in Thailand, it is important to be aware of the risk of animal bites. Here are some tips on preventing and treating animal bites:

Preventing Animal Bites:

  • Avoid touching or feeding animals you do not know.
  • Do not allow animals to lick open wounds or get their saliva in your eyes or mouth.
  • Stay away from rodents and their urine and faeces.
  • Supervise travelling pets closely and do not let them come into contact with local animals.
  • If you wake up in a room with a bat, seek medical care immediately as bat bites may be hard to see.
  • Be extra cautious around dogs, bats, monkeys, sea animals such as jellyfish, and snakes.
  • Dress appropriately to prevent bug bites, such as wearing long sleeves, trousers, footwear, and hats.
  • Use insect repellent containing DEET or other repellents such as picaridin or OLE.
  • Avoid bright colours and strong scents, as these can attract mosquitoes.
  • Sleep under a mosquito net, especially in remote or undeveloped areas.
  • Choose accommodation with screens and fans to keep insects out.
  • Avoid areas with still water, as mosquitoes breed in slow-moving or stagnant water.

Treating Animal Bites:

  • If bitten or scratched by an animal, immediately wash the wound with soap and clean water and seek medical attention.
  • Inform your doctor about the bite when you return to your home country.
  • For mosquito bites, clean the bite area with soap and water, use a cold compress to reduce swelling, and take antihistamines to relieve itching and swelling. Avoid scratching the bite.
  • For fly bites, wash the bite with soap and warm water, apply antiseptic cream or spray, and apply ice for 15 minutes several times a day. Avoid scratching, as this may break the skin and cause an infection.
  • For tick bites, remove the tick completely, including the head and mouth, and cleanse the area. If a rash develops at the site of the bite or elsewhere, along with fever or muscle aches, see a doctor and get tested for Lyme disease. Antibiotics such as doxycycline can prevent tick-borne diseases.
  • For scorpion stings, use strong analgesia for pain relief.
  • For centipede bites, apply ice packs to relieve pain.
  • For hornet stings, seek medical attention if you receive multiple stings, as the venom can be lethal even to those who are not allergic.
  • For bed bug bites, wash the bites with soap and warm water, apply antiseptic spray or lotion, and use antihistamines to stop itching.
