Malaria is spread by mosquitoes. If you are living in, or will be traveling to, an area where there is a chance of getting malaria, the following mosquito-control measures will help to prevent infection:
- Avoid going out between dusk and dawn because it is at these times when mosquitoes most commonly bite.
- If possible, sleep in a screened or air-conditioned room or under mosquito netting, preferably netting coated or soaked with pyrethrum, to avoid being bitten by malaria-carrying mosquitoes.
- Remain in air-conditioned or well-screened rooms to reduce contact with mosquitoes
- Wear long-sleeved shirts or blouses and long trousers to protect your arms and legs, especially from dusk through dawn when mosquitoes are out.
- Apply mosquito repellent, preferably one containing DEET, to uncovered areas of the skin from dusk through dawn when mosquitoes are out.
- Use mosquito coils or sprays to kill mosquitoes in living and sleeping quarters during evening and night-time hours.
