A collaborative study unusually brings together the health and development communities.

A widely cited example suggests that a 10 per cent reduction in malaria is associated with 0.3 per cent growth in Gross Domestic Product in sub-Saharan Africa.**
Steve Lindsay, Professor in the School of Biological and Biomedical Sciences, at Durham University said: "There has long been an association between poverty and malaria, but here we clearly demonstrate that in impoverished communities it is the poorest who suffer most, irrespective of where they live in the world." The fact that the chances of contracting the disease are so much higher among the poorest of the poor compared with the least poor is really quite startling.
"Wealth is positively associated with other factors known to be beneficial in combating the disease, including better educated parents, greater quality of housing, better access to treated bednets and antimalarials and improved nutritional status of children. Malaria and poverty therefore constitute a vicious cycle for the poorest households, exacerbating variation in health and wealth."
Although there has been a significant reduction in the instances of the disease globally over the last ten years, malaria remains one of the most significant global public health problems. According to the World Health Organisation, there were about 219 million cases of malaria in 2010 and an estimated 660,000 deaths. Africa is the most affected continent: about 90 per cent of all malaria deaths occur there.
Professor Lindsay said: "Long-lasting insecticidal nets and indoor residual spraying are both highly efficient ways of reducing transmission quickly and, combined with anti-malarial drugs, are undoubtedly a major reason for the decline in malaria seen in sub-Saharan Africa." However, such pressure on mosquito and parasite populations has already led to the spread of resistant strains of mosquitos and malaria parasites.

"Many aspects of development can protect against malaria, such as better housing or land drainage. In Khartoum, Sudan, malaria control has focused on improving drainage in the city, repairing leaking water pipes and changing irrigation techniques to reduce standing water, at relatively low cost. Malaria control programs elsewhere could adopt similar policies."
Professor Richard Smith, Health Economist at the London School of Hygiene & Tropical Medicine, said:
"The analysis represents a comparison of the very poorest children with the least poor children within highly impoverished communities. The difference in the odds of malaria in the poorest children are likely to have been even greater if the studies were expanded to include children from wealthier homes."
The research also involved collaborators at the Institute of Development Studies in Brighton, and the National Malaria Control Program, Khartoum, Sudan.
The research team advocates that development programmes should be an essential component of malaria control. Increased wealth and improved standards of living directly stemming from socio-economic development could prove fundamental in ensuring that malaria transmission continues to decline in much of Asia, South America and Africa, as witnessed historically in Europe and North America.
