Thailand is a hugely popular country for people exploring the world, as well as being a growing tourist destination. Its vibrant ways of life, colourful atmosphere and fascinating culture makes it a popular destination for people seeking something a little bit different.

The country is also home to a number of diseases which can be serious if contracted. Fortunately, you can help to avoid them by seeking advice about which vaccinations should be considered when travelling to Thailand.

Vaccinations help protect against these diseases and you can be vaccinated at participating Boots pharmacies. We’ll be able to advise you about the diseases you may encounter and steps you can take to help keep yourself safe while travelling in Thailand depending on things like:

• Which regions you are visiting 

• What activities you are doing

• Your age and general health

Book an appointment

We recommend booking an appointment with a Boots pharmacist six to eight weeks before you travel. However, even if time is short, we can still help you with options to consider.

Diseases in Thailand

Below are some of the diseases you may need protection against when you’re in Thailand. 

You can use our quick check tool to get a list of diseases that may be present in the country and vaccinations you may consider for your destination.


Malaria is high risk for those rural travellers along Thailand’s borders with Cambodia, Laos and Myanmar. There is a low risk in the rest of the country, while no risk in Bangkok, Chiang Mai, Chiang Rai, Koh Phangan, Koh Samui and Pattaya – although bite avoidance measures are recommended.

Malaria is a blood infection which can be fatal. It’s transmitted by mosquitoes, so it’s best to avoid being bitten by taking steps like using mosquito nets and insect repellent.

Anti-malarial tablets may be recommended to you depending on your travel plans. Our pharmacists can help you work out which ones may be suitable for you.

Yellow fever

Yellow fever is a viral infection transmitted by mosquitoes and can be fatal in some people.

A yellow fever vaccine is only needed if you are travelling from another country with a risk of yellow fever. That includes spending 12 hours at an airport located in a country with a high risk of yellow fever.

Your pharmacist will give you the latest advice for your trip.


Rabies is a serious viral infection which affects the nervous system and is almost always fatal unless treated early. 

It’s passed onto humans when broken skin comes into contact with the saliva of an infected animal, such as bats. You're at higher risk in remote areas where access to medical care may be limited.

Hepatitis A

Hepatitis A is a viral liver infection caught from contaminated food and water. The risk is higher in areas with poor sanitation, so taking steps like washing your hands after using the toilet is important. 

Hepatitis B

Hepatitis B is a viral liver disease spread through infected blood and other bodily fluids. The risk is higher for certain people, for example having unprotected sex.


Typhoid is a bacterial infection spread through poor sanitation. Symptoms include stomach cramps and diarrhoea. Those at increased risk are travellers visiting friends and relatives. All travellers are advised to maintain good personal, food and water hygiene measures.


Cholera is a bacterial infection which can cause watery diarrhoea. It is transmitted through eating contaminated food and drinking contaminated water. Travellers are advised to maintain good personal, food and water hygiene measures.

Japanese encephalitis

This brain infection is spread by mosquitoes and symptoms include paralysis and seizures. 


A persistent cough is typical of tuberculosis (TB), which is spread in a similar way to colds and flu. Travellers in Thailand are advised to avoid close contact with those suffering with infectious pulmonary TB.


Tetanus is an infection caused by bacteria and can lead to the tightening of muscles in the body which can affect swallowing and breathing. If you’ve not had a tetanus dose in the last 10 years then a booster dose may be advised.


Diphtheria is a highly contagious bacterial infection and usually affects the nose and throat. If you’ve not had a diphtheria dose in the last 10 years then you may consider a booster dose.

Childhood immunisations

No matter where you are travelling to, it’s recommended your childhood immunisations are up to date for:

• Measles, mumps and rubella

• Diphtheria, tetanus and polio
