A new global malaria estimate dramatically increases the number of cases worldwide, especially in Southeast Asia.
An international team of researchers from Kenya, Thailand, and Britain says the number of malaria cases is much higher than previous estimates by the World Health Organization (WHO).
Their new map of malaria distribution, published in the journal Nature, estimates that about a half a billion cases occurred in 2002. This is about 50 percent more than WHO estimates globally and double for areas outside Africa.
The new numbers show Africa still bears the brunt of malaria. But one of the mappers, Bob Snow of the Kenya Medical Research Institute in Nairobi, says they lower Africa's share of the global burden from 90 percent.
