Insecticide-treated durable wall lining (ITWL): future prospects for control of malaria and other vector-borne diseases
Abstract While long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) are the cornerstones of malaria vector control throughout sub-Saharan Africa, there is an urgent need for the development of novel insecticide delivery mechanisms to sustain and consolidate gains in disease redu...
