Africa: Malaria: a changed climate

After decades of decline, malaria has been on the rise in many parts of Africa - an estimateby the World Health Organisation is that, in some parts of the continent, malaria mortality in young children almost doubled from the 1980s to the 1990s. The disease causes some 3,000 deaths each day and imposes huge losses in economic productivity. Is this resurgence a sign of increased transmission caused by climate change? Probably not, according to results presented by in the Proceedings of the National Academy of Sciences, which conclude that future climate change will not affect transmission.
