Malaria is spread by the bites of certain kinds of infected female 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:
- If possible, avoid going out between dusk and dawn because it is at these times that mosquitoes most commonly bite.
- Wear long-sleeved shirts and long trousers to protect your arms and legs, especially from dusk through dawn when mosquitoes are out.
- Apply insect repellant, preferably one containing DEET, to uncovered areas of the skin from dusk through dawn when mosquitoes are out.
- If possible, sleep in a screened or air-conditioned room or under mosquito netting sprayed with insecticide to avoid being bitten by malaria-carrying mosquitoes.
- Use mosquito coils or sprays to kill mosquitoes in living and sleeping quarters during evening and nighttime hours.
