Households in the intervention (n = 287) and control (n = 289) neighborhoods were randomly sampled and the outcomes collected before the intervention (October 2015) and after the intervention (October 2016). The intervention reduced residents' exposure to dengue vector bites (vector saliva biomarker difference -0.08 [95% CI -0.11 to -0.04]). The pupae index declined in the intervention neighborhood (from 162.14 to 99.03) and increased in the control neighborhood (from 218.72 to 255.67). Residents in the intervention neighborhood were less likely to associate dengue with malaria (risk ratio 0.70 [95% CI 0.58-0.84]) and had increased knowledge about dengue symptoms (risk ratio 1.44 [95% CI 1.22-1.69]). Our study showed that well-planned, evidence/community-based interventions that control exposure to dengue vectors are feasible and effective in urban settings in Africa that have limited resources. specialized BURKINA FASO OUAGADOUGOU 056 052 102 24 10 1859-1867 2018 1080-6040 https://www.documentation.ird.fr/hor/fdi:010074022 10.3201/eid2410.180069 1080-6040 [F B010074022] https://www.documentation.ird.fr/hor/fdi:010074022 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers18-09/010074022.pdf IRD - Base Horizon / Pleins textes 2018-10-03 2023-07-11 fdi:010074022 fre
