For the first time in almost forty years, researchers are creating a global map of malaria risk. The Malaria Atlas Project, or MAP, will help identify populations at particular risk and predict the impact of the disease, allowing health resources to be targeted at those areas most at risk. Malaria is thought to kill over a million people every year, mostly children and pregnant women.
The research, funded by the Wellcome Trust, the UK's largest biomedical research charity, involves a collaboration between the Kenya Medical Research Institute (KEMRI) and the University of Oxford. Details and goals of the project are announced today in the open access journal PLoS Medicine.
Researchers from Kenya and Oxford will use information from satellites, population censuses and other electronic data related to factors that determine the presence of mosquitoes carrying the malaria parasites and the likelihood they will infect humans. Statistical approaches will enable comparisons to be made between areas where information exists with areas where there is no information to fill in the "gaps" to create a global map of malaria risk worldwide.
"At the moment, information on malaria infections and the impact of the disease remains the subject of best guesses based on national reporting systems, historical data or unvalidated models of malaria distribution," says Dr Simon Hay from the University of Oxford, who is based at KEMRI. "Resources for tackling malaria are driven by a mixture of perception and politics rather than an objective assessment of need. Clearly, this situation is untenable."
New anti-malarial drugs and commodities to prevent infection are available, but these are often expensive and the researchers are concerned that without an accurate measure of the impact of malaria, global and national finances will not be able to meet the need for these interventions.
