Malaria is a major health problem in tropical and subtropical parts of the world. It is spread by the bites of infected mosquitoes. Some forms can be fatal, others produce a high fever and may lead to kidney, liver, brain and blood complications. Malarone is a medication used to treat and prevent malaria. It contains a combination of atovaquone and proguanil. Malarone works by interfering with the growth of parasites in the red blood cells of the human body.
