The World Health Organization (WHO) reports that about 243 million people became seriously ill from
malaria in 2008, and almost a million people died.1
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.
