The Archbishop of Canterbury has backed calls for Africa to be “blanketed” with bed nets as part of the battle to eradicate malaria.

Dr Rowan Williams said in spite of being preventable and treatable, the blood disease – caused by a parasite transmitted by the mosquito – was still killing nearly a million people every year.

In a message recorded to mark World Malaria Day on Sunday, Dr Williams called on the world to put its “energy and imagination” behind efforts to achieve the goal of getting rid of malaria deaths by 2015.

“One of the things that I was taught when I was growing up was that among the greatest achievements of modern science was the identification of where malaria came from, the great steps that have been made to eradicate malaria from the world,” he said.

“That was many years ago and in the intervening years, tragically the challenge of malaria has grown worse not better.

“Half the world’s population is at risk from malaria, about a million people die because of it every year and not surprisingly the cost is highest among those most vulnerable and the youngest.”

The message was recorded by Dr Williams to support the global coalition United Against Malaria.

Campaigners are working towards a United Nations target of providing bed nets to everyone at risk by the end of this year with the aim of eradicating malaria deaths by 2015.

Ethiopia, Rwanda and Eritrea have been highlighted for their success in reducing malaria deaths by more than a half in just a few years through the use of bed nets, medicines and spraying.
