Large-scale use of mosquito larval source management for malaria control in Africa: a cost analysis
Abstract Background At present, large-scale use of two malaria vector control methods, long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) is being scaled up in Africa with substantial funding from donors. A third vector control method, larval source management (LSM), has been...
