Isn’t much of the decrease in malaria up in that area due to deforestation?
Deforestation is nothing new in that area, and there has been some decline in cases corresponding to disappearing forests. But the data from the village malaria workers shows that the dramatic decline in cases started shortly after the widespread distribution of the insecticide-treated mosquito nets in May to June 2009, and then continued to fall further as the village-based early diagnosis and treatment services were rolled out.
