Treatment involves the use of anti-malarial medications in addition to supportive therapy. Artemisinin-based combination therapy (ACT) is used for treatment of Plasmodium falciparum malaria. Hospitalisation is needed for severe malaria with complications.

How to prevent malaria?

Individuals living in or travelling to malaria-affected areas are advised to take preventive measures including:

• Starting appropriate chemoprophylaxis, or medicines that can prevent disease before exposure.

• Avoiding exposure to mosquitoes between dusk and dawn, when female Anopheles mosquitoes are most active.

• Staying in rooms with insect screens on windows and doors, or air-conditioning.

• Wearing long, protective clothing that cover most of one’s body.

• Using effective insect repellent containing DEET, Picaridin, or IR3535 as the active ingredient and re-applying every four to six hours on exposed skin.

There is currently no approved vaccine against malaria in Singapore.
