  • Answer: A mosquito.
    The Anopheles mosquito, shown here, can carry the parasite that causes malaria. When an infected mosquito bites a human, it injects saliva that contains the infectious form of the parasite into a person's bloodstream. Malaria symptoms are high fevers, shaking chills, and flu-like illness. Bed nets, insecticides, and antimalarial drugs are effective tools to fight malaria in areas where it is transmitted. The disease is mostly a problem in developing countries with warm climates, with 85 percent of yearly deaths occurring in sub-Saharan Africa.
