As a result of the increased levels of resistance, SP has been gradually removed from malaria control programs worldwide.
For example, in the sub-Saharan African region, from 2010 to 2013, an estimated 443 million LLINs have been delivered, reaching a coverage of up to 60%, a dramatic improvement from only 10% coverage in 2000. 1 A major threat for malaria control programs worldwide is the development and spread of insecticide resistance in vector populations.
Worldwide support for malaria control in Africa is probably little more than $50m-75m 50m-75m although malaria claims perhaps 2m lives annuallyear million or more directly, althoughher malaria or so from diseases in whiclaimsaria is a factor).
A recent worldwide trend of attention to malaria control has come with accompanying financial support directed towards the development of new drugs, anti malarial vaccines and alternatives for vector population management [10].
It also highlights, say researchers, the urgent need for beefed-up malaria control along the Thai-Cambodian border and more action worldwide against misuse of malaria drugs.
Accurate information is needed not only to improve our knowledge of malaria epidemics, but also to assess progress of malaria control initiatives that aim to decrease deaths from malaria worldwide by 50% by 2010 (5 ).
By contrast, the Lives Saved Tool (LiST) estimated the impact of up to dozens of child survival interventions (including malaria control interventions) across 42 low- and middle-income countries worldwide [ 9].
Targeting the mosquito vector is the most effective way to prevent malaria transmission; worldwide, this method accounts for more than half of malaria control expenditures (1, 2 ).
Prof Sir Richard Feachem, director of the Global Health Group at the University of California, San Francisco, the study's lead author, said: "The malaria control strategies implemented over the last decade have been highly successful in reducing malaria worldwide.
