  • How do people get malaria?

    When bitten by infected mosquitoes which carry the malaria parasite.1

  • Which countries are affected by malaria?

    Most countries in Central and South America, Africa, the Middle East and Asia (see map).2

  • What are the symptoms of malaria?

    Fever, headache, and chills. Symptoms usually occur between 10 and 15 days after being bitten, therefore you may start to feel ill when you are back home after your trip.1

  • Can I prevent getting malaria?

    You can take the following precautions to help reduce your risk of infection:

    • Visit your nearest convenient pharmacy or specialist travel health clinic for a risk assessment before your trip
    • Take steps to avoid mosquito bites when mosquitoes are most active (between dusk and dawn)1,4
    • Use a recommended insect repellent containing either 20% Picaridin (e.g Moskito Guard®), DEET, PMD or OLE, IR3535 or 2-undecanone4
    • Wear appropriate clothing (e.g loose fitting long-sleeved clothes, long trousers, socks and shoes) to minimise exposed skin5
    • Use mosquito nets if you are sleeping or resting in unscreened accommodation or sleeping outdoors during the day or night5
