Uso de máscara de tecido pela população na contenção da disseminação da COVID-19: scoping review

Abstract

Introduction:Covid-19 is a highly transmissible disease, caused by the SARS-CoV-2 coronavirus, characterized from infections with asymptomatic conditions to severe respiratory conditions. Objective:to map the evidence and gaps in the literature on the use of fabric masks by the population as a strategy to contain the spread of Covid-19. Methods:It is a Scoping Review based on articles from the PUBMED, Cochrane, BVS and LILACS databases, carried out without restriction of language and period of publication. It was developed according to the PRISMA-ScR guideline. Results:498 articles were found, eleven of which were included after analyzing the inclusion and exclusion criteria. Narrative and systematic review studies, experimental studies, clinical trials, mathematical models and commentary, update and perspective articles were used. Studies have shown that fabric masks, such as cotton with high thread density, reduce droplet transmission and thus can be effective in reducing contamination by SARS-CoV-2. Conclusion:In low-risk situations, the use of multi-layer fabric masks provides protection against the transmission of covid-19. However, there is a need for more research related to the ideal model, the influence of moisture produced by expiration, the time of use and the number of washes.
