Community-based interventions for preventing COVID-19 transmission in low- and middle-income countries:  A systematic review

Abstract

Background World Health Organisation (WHO) has approved and recommended several public health measures to halt the Coronavirus Disease 2019 (COVID-19) pandemic. The implementation of recommended interventions vary between higher income and Low and Middle-Income Countries (LMICs). The economical constraints within LMICs posed challenges in accessing resources for COVID-19 prevention. The study aimed to identify the workable community-based interventions being utilised in LMICs.Main body We applied systematic review approach for this study. Included articles were searched in eight online databases. The analysis was guided by the acceptable of best practice developed by the PROSPERO and COCHRANE for systematic search and selection of articles using pre-defined search terms. Furthermore, a PRISMA flow diagram was used to show the number of articles retrieved, retained, excluded with rationales given for every action. Studies conducted on community-based intervention for preventing COVID-19 and levels of knowledge, attitudes and practice (KAP) on community-based intervention for preventing COVID-19 regardless of the design were included. A mixed method appraisal tool (MMAT) was used to appraise studies.Six studies from LMICs were included for detail analysis after the systematic review screening process from 10,100 articles. The quality assessment using MMAT tool appraised these articles were all in highest quality. Among the six articles, 10 community-based interventions were implemented in LMICs. The three key workable and implemented interventions are: use of masks, social distance and hand wash. The review identified varying levels of KAP between LMICs and social-demographical factors affecting KAP in these settings.Conclusion This systematic review has identified the community-based interventions implemented in LMICs to prevent COVID-19 during the pandemic and key factors affecting the level of KAP among the population. This study re-affirms the importance of effective and suitable implementation of the identified interventions. More studies need to be conducted in LMICs to establish the effectiveness and adoption of the implemented and recommended interventions.
