Deaths from malaria have been falling steadily since around 2004. The improvement is down to several factors. A total of 145 million long-lasting insecticide-treated nets were delivered to sub-Saharan Africa last year, a huge increase on 2009. Spraying the walls of homes with insecticide is another effective means of reducing malaria. Once infected, it is vital that treatment begins quickly. Rapid diagnostic tests are being increasingly used. [Source: BBC News]
