Going on holiday or travelling to a tropical destination? Learn how to avoid malaria and put your mind at ease.

In this article we discuss:


What is Malaria?

Let’s start with the basics. You’re going on holiday and have been warned of malaria – but what exactly is it and how can it affect you?

Malaria is a disease spread by parasites that infect mosquitoes – flying insects found throughout the tropics. A mosquito infected with malaria can pass the disease on to a human through biting, a small action that may often go unnoticed, therefore, it is important that you are fully protected and aware of what precautions to take when travelling abroad.

Malaria is not contagious cannot be passed from human to human, it is only transmitted through mosquitoes.  

Symptoms of malaria include:

  • High temperature
  • Cyclic fever –  feeling hot and shivery
  • Feeling fatigued
  • Muscle aches
  • Nausea and vomiting
  • Headache

These symptoms may appear weeks or even months after you have contracted the disease. If symptoms present within three months of returning from a country with a risk of malaria you should contact your GP, even if all recommended measures against malaria were taken.

Which destinations are affected?

Malaria is widespread, being present throughout the tropics and subtropics – popular holiday destinations.
The NHS website Fit for Travel gives up to date information on which countries carry a risk of malaria. These areas are defined as ‘high risk’ and you are advised to be taking extra precautions against the disease, such as antimalarial tablets, when visiting.  

Even within the same country, the risk of malaria can differ between regions, therefore, it is good to know exactly where you are going. Malaria risk may also differ depending on the time of year you are travelling.  


Antimalarials are tablets that prevent you from becoming infected with malaria when taken correctly and consistently.

Resistance to antimalarials differs throughout the globe – what will prevent malaria in one country may not be equally effective in another. If you are travelling across several countries you should check which malaria tablets are effective as you may need to take more than one type throughout your trip.

Antimalarials can be purchased from an online pharmacy, within a pharmacy or through your doctor. You should note that they are not routinely given on the NHS so you may have to pay extra for them if you get them on prescription.

Common antimalarials include:

It is important to read the dosage instructions carefully before taking your anti-malaria tablets. Most tablets require to be taken a few days before entering into a malaria region and a few weeks after leaving, as well as the duration you are there. It is also important that you are compliant with taking the tablets as missing tablets may not provide complete protection.

Prevention is better than cure

Although antimalarials are a successful way to prevent malaria they are not considered 100% effective. Preventing mosquito bites will reduce your chances of contracting the disease further.

Simple steps you can take are:

  • Staying covered up by wearing loose long sleeved t-shirts and trousers
  • Sleeping with a mosquito net
  • Using an insect repellent containing DEET, a chemical effective against mosquitos
  • Washing your clothes with an insect repellent containing washing powder

By taking these simple preventative measures and taking malaria tablets you can enjoy your holiday stress-free without the worry of malaria!
