Background Progress in malaria control has stalled in recent years and innovative surveillance and response approaches are needed to accelerate malaria control and elimination eforts in endemic areas of ***‑ing on a previous China-UK-Tanzania pilot study on malaria control,this study aimed to assess the impact of the 1,7-malaria Reactive Community-Based Testing and Response(1,7-mRCTR)approach implemented over two years in three districts of *** The 1,7-mRCTR approach provides community-based malaria testing via rapid diagnostic tests and treat‑ment in villages with the highest burden of malaria incidence based on surveillance data from health *** used a diference-in-diferences quasi-experimental design with linear probability models and two waves of crosssectional household surveys to assess the impact of 1,7-mRCTR on malaria *** conducted sensitivity analyses to assess the robustness of our results,examined how intervention efects varied in subgroups,and explored alternative explanations for the observed *** Between October 2019 and September 2021,244,771 community-based malaria rapid tests were com‑pleted in intervention areas,and each intervention village received an average of 3.85 rounds of *** prevalence declined from 27.4%at baseline to 11.7%at endline in the intervention areas and from 26.0%to 16.0%in the control areas.1,7-mRCTR was associated with a 4.5-percentage-point decrease in malaria prevalence(95%confdence interval:−0.067,−0.023),equivalent to a 17%reduction from the *** rufji,a district characterized by lower prevalence and where larviciding was additionally provided,1,7-mRCTR was associated with a 63.9%decline in malaria *** The 1,7-mRCTR approach reduced malaria *** implementation interruptions due to the COVID-19 pandemic and supply chain challenges,the study provided novel evidence on the efectiveness of community-based reactive approache
