Because malaria is developed from the bite of an infected mosquito, malaria can be prevented by using mosquito net treated with insecticides, making sure all windows and doors are covered with screens, and using insecticides on interior walls where malaria is a major problem. If you are traveling in an area where the risk of malaria is high, make sure you wear long-sleeved shirts, long pants, and other protective clothing to protect yourself from mosquito bites-in particular from dusk until morning. DEET and other insect repellants can also be used to ward off mosquitoes. Preventive medications can also be prescribed as anti-malaria tools. Be sure to check with a doctor about the side effects of any medications being prescribed to you.
