Translating research into action to prevent malaria

The USAID | TRAction Project researches new strategies to reduce malaria transmission and tests and monitors the efficacy and cost-effectiveness of vector control tools currently in use. Durable insecticide-treated wall liners, a recent innovation, may be beneficial for management of insecticide resistance. The cost of these wall liners is roughly equal to two to three rounds of indoor residual spraying and they are effective for three to four years—spray treatments last only three to twelve months between applications. Durable insecticide-treated wall liners are designed to supplement long lasting-insecticide treated bed nets (LLIN) to offer more protection and could be a cost-effective malaria prevention method.

The National Institute for Medical Research (NIMR), in collaboration with the Kilimanjaro Christian Medical College and London School of Hygiene and Tropical Medicine, is conducting a trial on the effectiveness of insecticide-treated durable wall liners as a vector-control measure in the Muheza district of the Tanga region in North Eastern Tanzania. The study (a two-arm cluster randomized controlled trial) will assess the effectiveness of durable wall liners used in combination with LLIN, compared to the effectiveness of LLINs alone. In the intervention area, the liners have been installed  in households, which also received LLINs. In the control area, households have received only LLINs. To determine the incidence of new malaria cases in each arm of the study, children enrolled in the study are receiving monthly follow ups for 12 months. Additional data regarding (1) the impact of DL on entomological outcomes, (2) social acceptability, and (3) cost are also being collected.

TRAction will also disseminate materials to help programmers and policymakers better understand and utilize study findings in the broader context of current malaria prevention knowledge. In addition, a protocol paper has been submitted to a journal to explain the implementation process in greater depth. 

Findings from this study will contribute to best practices in malaria prevention programming and may help inform national and local level decision-making by policymakers.
