People traveling to Africa may have a higher risk of infection because they frequently stay outdoors and often camp in rural areas where mosquitoes are common. There may be no risk of malaria (even in malaria-infested areas such as Southeast Asia and South America) if travelers stay in urban or resort areas where there are fewer mosquitoes.
In the United States 1,298 people developed malaria in 2008 (the most recent year for which statistics are available). Most of the people were infected with P. falciparum malaria. Two of the people died.2 Cases of malaria in the U.S. occur primarily in international travelers, military personnel, and immigrants from countries where malaria is present.
