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.
  • 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 insect repellent, 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 preferably netting coated or soaked with pyrethrum, 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.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
