World Malaria Risk Map Updated - With Surprising Conclusion

Mapping Malaria (HD) VIDEO

SciDev Net reports on a new World malaria map [that] could guide control policy. The revisions constitute the first update in over 40 years. Its preparers conclude that simple control measures such as bed nets are likely to suffice over broad areas where high exposure to malaria had been previously been assumed to call for eradication. Please read the full story at SciDevNet for discussion of precision limits. The key conclusion is presented below.

They found that fewer people live in high-risk malaria areas than previously thought. Some 70 per cent of the 2.4 billion people in malaria-prone areas live in low-risk areas where mathematical models predict that simple interventions such as bednets could eradicate the disease.

"The map shows us, surprisingly, that the majority of the endemic world is in fact very low risk," says Bob Snow, one of the report's authors, from the Kenya Medical Research Institute and the UK-based University of Oxford.

The full scientific paper introducing the new map, World Malaria Map: Plasmodium falciparum Endemicity in 2007, is available here, on PlosMedicine.
