ABSTRACT
OBJECTIVE: The government of the Democratic Republic of Congo (DRC) responded to COVID-19 with policy measures, such as business and school closures and distribution of vaccines, which rely on citizen compliance. In other settings, prior experience with effective government programmes has increased compliance with public health measures. We study the effect of a national water, sanitation, and hygiene programme on compliance with COVID-19 policies. METHODS: Prior to the COVID-19 pandemic, 332 communities were randomly assigned to the Villages et Écoles Assainis (VEA) programme or control. After COVID-19 reached DRC, individuals who owned phones (590/1312; 45%) were interviewed by phone three times between May 2020 and August 2021. Primary outcomes were COVID symptoms, non-COVID illness symptoms, child health, psychological well-being, and vaccine acceptance. Secondary outcomes included COVID-19 preventive behaviour and knowledge, and perceptions of governmental performance, including COVID response. All outcomes were self-reported. Outcomes were compared between treatment and control villages using linear models. RESULTS: The VEA programme did not affect respondents' COVID symptoms (-0.11, 95% CI -0.55 to 0.33), non-COVID illnesses (-0.01, 95% CI -0.05 to 0.03), child health (0.07, 95% CI -0.19 to 0.33), psychological well-being (-0.05, 95% CI -0.35 to 0.24), or vaccine acceptance (-0.04, 95% CI -0.19 to 0.10). There was no effect on village-level COVID-19 preventive behaviour (0.03, 95% CI -0.23 to 0.29), COVID-19 knowledge (0.16, 95% CI -0.08 to 0.39), or trust in institutions. CONCLUSIONS: Although the VEA programme increased access to improved water and sanitation, we found no evidence that it increased trust in government or compliance with COVID policies, or reduced illness.

INTRODUCTION: Inadequate water and sanitation is a central challenge in global health. Since 2008, the Democratic Republic of Congo government has implemented a national programme, Healthy Villages and Schools (Villages et Ecoles Assainis (VEA), with support from UNICEF, financed by UK's Foreign, Commonwealth and Development Office. METHODS: A cluster-level randomised controlled trial of VEA was implemented throughout 2019 across 332 rural villages, grouped into 50 treatment and 71 control clusters. Primary outcomes included time spent collecting water; quantity of water collected; prevalence of improved primary source of drinking water; and prevalence of improved primary defecation site. Secondary outcomes included child health, water governance, water satisfaction, handwashing practices, sanitation practices, financial cost of water, school attendance and water storage practices. All outcomes were self-reported. The primary analysis was on an intention-to-treat basis, using linear models. Outcomes were measured October-December 2019, median 5 months post-intervention. RESULTS: The programme increased access to improved water sources by 33 percentage points (pp) (95% CI 22 to 45), to improved sanitation facilities by 26 pp (95% CI 14 to 37), and improved water governance by 1.3 SDs (95% CI 1.1 to 1.5), water satisfaction by 0.6 SD (95% CI 0.4 to 0.9), handwashing practices by 0.5 SD (95% CI 0.3 to 0.7) and sanitation practices by 0.3 SD (95% CI 0.1 to 0.4). There was no significant difference in financial cost of water, school attendance, child health or water storage practices. CONCLUSION: VEA produced large increases in access to and satisfaction with water and sanitation services, in self-reported hygiene and sanitation behaviour, and in measures of water governance.
