ABSTRACT
Resumo O objetivo deste artigo é avaliar a eficácia das máscaras faciais padrão tecido não tecido (TNT) para a prevenção de doenças respiratórias (MERS CoV, SARS-CoV e SARS-CoV-2) na população. Foi realizada busca nas bases de dados Medline, Embase, Cinahl, The Cochrane Library, Trip. Também busca complementar no Google Acadêmico, Rayyan e medRxiv. Não foram aplicados filtros relacionados a data, idioma ou status de publicação. Títulos e resumos foram rastreados e, posteriormente, textos completos foram avaliados. Foram incluídos três estudos: um ensaio clínico randomizado tipo cluster e duas revisões sistemáticas. O ensaio clínico indica benefício potencial de máscaras médicas para controle da fonte de infecção, para a doença respiratória clínica. Em uma das revisões sistemáticas, não foi possível estabelecer relação conclusiva entre uso da máscara e proteção contra infecção respiratória. Por fim, outra revisão sistemática demonstrou que máscaras são eficazes na prevenção da propagação de vírus respiratórios. As evidências apontam para benefício potencial das máscaras faciais padrão TNT. Para o cenário atual de pandemia por COVID 19, recomenda-se educação sobre uso adequado de máscaras, associado a medidas individuais de proteção. Objectives: to evaluate the effectiveness of non-woven face masks for the prevention of respiratory infections (MERS CoV, SARS-CoV, and SARS-CoV-2) in the population. Methods: search in Medline, Embase, Cinahl, The Cochrane Library, Trip databases. Google Scholar, Rayyan and medRxiv were also consulted for complementary results. No filters related to date, language or publication status were applied. Titles and abstracts were screened, and later, full texts were evaluated. Results: three studies were included: a randomized cluster clinical trial and two systematic reviews. The clinical trial indicates a potential benefit of medical masks to control the source of clinical respiratory disease infection. In one of the systematic reviews, it was not possible to establish a conclusive relationship between the use of the mask and protection against respiratory infection. Finally, another systematic review indicated that masks are effective in preventing the spread of respiratory viruses. Conclusion: Evidence points to the potential benefit of standard non-woven face masks. For the current pandemic scenario of COVID-19, education on the appropriate use of masks associated with individual protection measures is recommended.
