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:
- Remain in air-conditioned or well-screened rooms to reduce contact with mosquitoes.
- If possible, sleep under mosquito netting, preferably netting coated or soaked with permethrin, to avoid being bitten by malaria-carrying 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 a pyrethrum-containing flying insect spray to kill mosquitoes in living and sleeping quarters during evening and nighttime hours.
Contact your doctor right away if you experience cough, difficulty swallowing, dizziness, fast heartbeat, hives, itching, puffiness or swelling of the eyelids or around the eyes, face, lips or tongue, shortness of breath, skin rash, tightness in chest, unusual tiredness or weakness, or wheezing. These could be symptoms of an allergic reaction.
Atovaquone and proguanil may cause your skin to be more sensitive to sunlight than it is normally. Be sure to wear protective clothing and a hat or apply a product to the skin that prevents sunburn before going outside.
