Governmental non-drug strategies for COVID-19 - Scoping review

Abstract

Background and objectives: The new coronavirus pandemic has so far caused around 3 million deaths worldwide and significant changes in the population's routine. Social distancing, the use of masks and general restrictions are advocated by governments as mandatory non-drug primary strategies, which must be incorporated into society for a long time. The present study aimed to evaluate the effectiveness of governmental non-drug strategies for COVID-19. Study design: This is a scoping review. Methodology: Search for studies at Medline / PUBMED, at the Cochrane Library and at EMBASE. DECS descriptors were used and there were no geographical and temporal restrictions on publications. The inclusion criteria involved human studies covering exposure to governmental non-drug strategies, with social distance, the use of masks and lockdown being a priority. Results: The search strategy retrieved 365 citations and, of these, 9 studies were included in this review. Discussion: Most studies involve observational studies and suggest that social distance, lockdown and the use of facial masks can reduce the incidence of new cases of COVID-19. Conclusion: The strategies of physical distance, lockdown and the use of facial masks had a beneficial result in most of the studies analyzed, contributing to the reduction of new cases of COVID-19.
