The aim of this research is to assess the effectiveness of insecticide-treated durable wall liners (DL) for malaria control in Tanzania. The DL is a thin sheet of insecticide-treated woven shade cloth that is fixed to the inner walls of houses, covering the walls and open eaves. The purpose of this research is to assess the added benefit of DL used in combination with long-lasting insecticidal bednets (LLINs) compared to LLINs used alone. Data collected through this study will provide important information to the Tanzanian National Malaria Control Program (NMCP) and malaria-endemic countries to guide future malaria control efforts and allocation of resources.
Insecticide treated nets (ITN) and indoor residual spraying (IRS) of houses provide effective malaria transmission control. There is conflicting evidence whether it is more beneficial to provide both interventions in combination.The London School of Hygiene and Tropical Medicine (LSHTM) conducted research to investigate whether the combination provides added protection compared to ITNs alone. In partnership with National Institute for Medical Research and Kilimanjaro Christian Medical College, LSHTM carried out a two arm randomized trial to determine the impact of ITNs and IRS on malaria transmission rates.
