Resumo
Acumulam-se evidências de que o uso de máscaras é uma medida indispensável de proteção à COVID-19, devido ao alto poder de transmissão do novo coronavírus por via respiratória, inclusive por indivíduos assintomáticos. Por sua vez, o uso das máscaras de tecido em locais públicos tem se consolidado como medida adicional de proteção às medidas de distanciamento social e higienização das mãos. Objetivou-se sistematizar as evidências científicas que justificam o amplo uso de máscaras de tecido como prevenção à COVID-19 e descrever a evolução dos posicionamentos contrários ou favoráveis ao seu uso em ambientes extradomiciliares, diante do avanço da pandemia do novo coronavírus pelo mundo. A triagem de artigos e documentos oficiais do Brasil e de outros países indica que o uso de máscaras em locais públicos tornou-se uma intervenção essencial graças ao potencial de reduzir a velocidade de propagação do novo coronavírus. Recomenda-se que o poder público adote estratégias para aumentar a oferta deste produto e fomente estudos para avaliação do impacto da medida no controle da pandemia no Brasil. É imperativo assegurar disponibilidade de máscaras a grupos socioeconomicamente desfavorecidos e garantir que determinados grupos raciais não sejam estigmatizados diante do uso de máscaras em ambientes extradomiciliares.

Abstract
There is increasing evidence that the use of masks is an indispensable protective measure against COVID-19, given the high transmissibility of the new coronavirus through the respiratory system, including by asymptomatic individuals. The use of cloth masks in public places has been established as a protective measure to be adopted alongside social distancing and hand hygiene. This narrative review aims to systematize the scientific evidence that informs the widespread use of cloth masks as a preventive measure against COVID-19 and to describe the evolution of positions contrary to or in favor of its use outside the home, in view of the advance of the new coronavirus pandemic globally. The scientific articles, technical notes, governmental decrees and other documents analyzed indicate that widespread use of masks has the potential to reduce the spread of the new coronavirus. We recommend that the Brazilian government adopt strategies to increase the supply of reusable cloth masks to the public, especially to vulnerable populations and to support studies on the impact of this measure to control the pandemic in the country. Finally, it is imperative to ensure that use of masks does not exacerbate stigmatization of racial groups that already face prejudice.

Introdução
Desde a emergência do vírus da síndrome respiratória aguda grave 2 (SARS-CoV-2), debates sobre medidas de controle da pandemia têm ganhado destaque na mídia e na literatura científica. Sabe-se que a transmissão do novo coronavírus entre humanos ocorre principalmente na interação pessoa-pessoa pelo contato com gotículas produzidas por via oral e nasal (na respiração, fala, tosse ou espirro de indivíduos infectados, sejam doentes ou assintomáticos) e que o vírus permanece em boas condições no ar por até três horas e em superfícies rígidas por até 72 horas11 Centers for Disease Control and Prevention (CDC).

A adoção de uma política universal de uso de máscaras descartáveis durante a pandemia, resultaria em uma demanda difícil de ser atendida ocasionando a escassez do equipamento de proteção para profissionais de saúde e demais usuários recorrentes2020 Wang M-W, Zhou M-Y, Ji G-H, Ye L, Cheng Y-R, Feng Z-H, Chen J.

No início de abril, a Organização Mundial da Saúde (OMS) recomendava que as máscaras descartáveis fossem utilizadas exclusivamente por profissionais de saúde, indivíduos imunossuprimidos e casos suspeitos ou confirmados do novo coronavírus. A OMS alertava ainda sobre a ausência de evidências que embasassem a indicação do amplo uso de máscaras feitas a partir de materiais alternativos99 World Health Organization (WHO).

Somente no dia 5 de junho de 2020, a OMS divulgou orientações para uso e fabricação de máscaras de pano como proteção contra a COVID-19, e passou a recomendar o amplo uso em locais onde há ampla transmissão da doença e em situações em que o distanciamento social não é possível, como no transporte público2222 World Health Organization (WHO).

Esse artigo tem o objetivo de realizar uma revisão narrativa da literatura sobre a eficácia e adesão ao uso de máscaras de tecido em locais públicos para a prevenção da COVID-19 e descrever a evolução dos posicionamentos contrários ou favoráveis ao seu uso em ambientes extradomiciliares, diante do avanço da pandemia do novo coronavírus pelo mundo.
Métodos
Esta revisão narrativa partiu do levantamento de artigos sobre o uso de máscaras no contexto do novo coronavírus, publicados na base Medline (PubMed), que só inclui publicações aprovadas por peer review2323 Chen Q, Allot A, Lu Z. Keep up with the latest coronavirus research. Nature 2020; 579(7798):193., contempla a base SciELO e também manuscritos em fase de pré-publicação (preprints) disponíveis nas bases do MedRxiv, constituindo, assim, o maior e principal repositório da literatura biomédica disponível.
Para a seleção de artigos relevantes, buscamos as palavras-chave “mask and covid” or “mask and coronavirus”, or “mask and covid-19”, or “mask and covid19” nos títulos e resumos de artigos publicados até o dia 12 de junho de 2020. Foram incluídos artigos originais, editoriais, cartas ao editor, comentários e revisões de literatura, em português, inglês e espanhol disponíveis na íntegra. Foram excluídos artigos que apresentassem dados exclusivos referentes ao uso de máscaras cirúrgicas (TNT e variantes), máscaras respiratórias (N95, FFP2) e descartáveis; que tratassem de máscaras faciais destinadas à cobertura de outras porções da face, não incluindo o trato respiratório (e.g. máscaras para os olhos e face shields) e referentes ao uso de máscaras apenas entre profissionais de saúde.
Além dos artigos científicos selecionados, foram consultados documentos oficiais estaduais e federais implementados no Brasil, tais como decretos, portarias e leis estaduais disponíveis no site LegisWeb2424 LegisWeb. LegisWeb [Internet]. [acessado 2020 Set 29]. Disponível em: https://www.legisweb.com.br/

; notas técnicas do Ministério da Saúde do Brasil (MS) e da Agência Nacional de Vigilância Sanitária (ANVISA); e regulamentações sobre o uso de máscaras de tecido em ambientes extradomiciliares adotadas em outros países no contexto da pandemia da COVID-19. Para tal, as informações foram extraídas do site Mask4All2525 Masks4All. What Countries Require or Recommend Masks In Public? [Internet]. [acessado 2020 Set 29]. Disponível em: https://masks4all.co/what-countries-require-masks-in-public
https://masks4all.co/what-countries-requ...
, uma organização não-governamental que reúne informações relativas à regulamentação do uso de máscaras em todos os países. Todas as fontes de informações descritas foram consultadas até o dia 12 de junho.
Uma síntese quantitativa dos principais achados dos artigos selecionados foi realizada, com extração das seguintes informações: autoria, revista, título, data de publicação, tipo de publicação e posicionamento relacionado à recomendação do uso de máscaras de tecido como medida de prevenção e controle da COVID-19 (Quadro 1). Os posicionamentos dos autores sobre o uso de máscaras de tecido no contexto da COVID-19 foram classificados como: i) A favor; ii) Sem posicionamento; e iii) Contra. A evolução temporal desses posicionamentos foi analisada de forma gráfica.
Artigos selecionados quanto ao seu posicionamento com relação ao amplo uso de máscaras de tecido.
Adicionalmente, extraíram-se informações referentes à adesão e eficácia do uso de máscaras de tecido descritas nos artigos selecionados. Uma síntese qualitativa dos principais achados sobre o uso de máscaras de tecido em ambientes extradomiciliares, os argumentos que embasaram os posicionamentos a favor e contra o seu uso, bem como possíveis diferenças observadas entre os países quanto à adoção dessa recomendação, também foi realizada. Dessa forma, as informações obtidas foram sintetizadas e discutidas com base nas evidências publicadas até o momento.
Resultados
A seguir são apresentados os resultados desta revisão narrativa, que não propôs fornecer uma descrição detalhada e exaustiva da literatura, mas sim explorar criticamente um tema ainda pouco conhecido.

Evidências acerca da efetividade do uso de máscaras como controle de doenças infecciosas respiratórias
Estudos anteriores à atual pandemia já haviam comprovado a efetividade do uso massivo de máscaras, inclusive de máscaras de tecido, em locais extradomiciliares como estratégia de controle à disseminação de doenças infecciosas respiratórias1010 Liang M, Gao L, Cheng C, Zhou Q, Uy JP, Heiner K, Sun C.

, a eficácia do uso de máscaras no combate a doenças respiratórias depende de três pontos principais: i) da capacidade de bloquear o vírus (eficácia da máscara); ii) da proporção de pessoas que a utilizam em público (aderência ao uso); e iii) da taxa de transmissão da doença.
Estudos ainda sugerem que, apesar de apresentarem uma eficácia menor do que as máscaras cirúrgicas, as máscaras de tecido, se usadas corretamente, funcionam como barreira mecânica à transmissão do vírus, impedindo ou reduzindo o contato dos indivíduos com gotículas contaminadas1818 Ma QX, Shan H, Zhang HL, Li GM. Potential utilities of mask-wearing and instant hand hygiene for fighting SARS-CoV-2.

Effectiveness of Common Fabrics to Block Aqueous Aerosols of Virus-like Nanoparticles. ACS Nano 2020; 14(6):7651-7658.. Esta redução ocorre porque, se uma gota contaminada atingir a trama do tecido de uma máscara ao invés da boca ou do nariz, ela tende a ficar retida, diminuindo o número de gotículas contaminadas que chegam às vias respiratórias. Ao evitar a contaminação de seus usuários, as máscaras de tecido ajudam a retardar a velocidade de evolução da epidemia3838 Han G, Zhou Y-H. Possibly critical role of wearing masks in general population in controlling COVID-19. J Med Virol 2020; 10.1002/jmv.25886.

e contribuem para o estabelecimento de uma curva epidêmica mais longa e plana9797 Mahase E. Covid-19: What is the evidence for cloth masks? BMJ 2020; 369:m1422.. Contudo, se as máscaras forem posicionadas ao rosto de forma inadequada, com eventuais aberturas laterais, podem ter sua efetividade protetora diminuída em até 60%5454 Konda A, Prakash A, Moss GA, Schmoldt M, Grant GD, Guha S. Aerosol Filtration Efficiency of Common Fabrics Used in Respiratory Cloth Masks. ACS Nano 2020; 14(5):6339-6347..
Pesquisadores da Universidade de Duke (EUA), analisaram 14 tipos de máscaras para avaliar sua eficácia na proteção contra gotículas respiratórias emitidas pela fala. Os resultados mostraram que, de fato, as máscaras profissionais N95 são as mais eficazes (redução da transmissão de gotículas para menos de 0,1%), seguidas pelas máscaras cirúrgicas de três camadas ou de polipropileno e algodão (redução da transmissão de gotículas em 90% ou mais, em comparação com a ausência de cobertura facial). As máscaras de tecido de algodão, feitas à mão, vieram na sequência, fornecendo boa cobertura, eliminando 70% a 90% das gotículas expelidas pela fala, e se equiparando ao desempenho das máscaras N95 com válvulas131131 Fischer EP, Fischer MC, Grass D, Henrion I, Warren WS, Westman E. Low-cost measurement of face mask efficacy for filtering expelled droplets during speech. Sci Adv 2020; 6(36):eabd3083..
Ainda sobre o poder de filtração das máscaras de tecido, um estudo realizado em Teipei não encontrou diferenças significativas na concentração de partículas entre 20-1.000 nm no ar em ambientes fechados (carro e quarto) após a permanência de pessoas gripadas utilizando máscaras de tecido de três camadas versus estas mesmas pessoas utilizando máscaras cirúrgicas9494 Ho K-F, Lin L-Y, Weng S-P, Chuang K-J. Medical mask versus cotton mask for preventing respiratory droplet transmission in micro environments. Sci Total Environ 2020; 735:139510., sugerindo poder de filtração semelhante entre os modelos. Nos Estados Unidos, diante da escassez de máscaras profissionais durante a pandemia da COVID-19, o CDC chegou a recomendar que fosse feito o uso de máscaras de tecido por profissionais de saúde que não atuam diretamente com pacientes infectados4545 Abd-Elsayed A, Karri J. Utility of Substandard Face Mask Options for Health Care Workers During the COVID-19 Pandemic. Anesth Analg; 131(1):4-6 ..
Evidências sobre o uso de máscaras em locais públicos na prevenção da COVID-19
Com relação à proporção de pessoas que fazem o uso de máscaras, há grande heterogeneidade nas normas adotadas por diferentes países e regiões e, também, na taxa de aderência destas populações, mesmo mediante indicação ao uso de máscaras. A aderência das pessoas à medida de prevenção depende, entre outros fatores, da consistência da informação veiculada pelo poder público, da confiabilidade da população nas autoridades públicas e sanitárias e no conhecimento da população acerca da doença132132 Goodman JL, Borio L. Finding Effective Treatments for COVID-19: Scientific Integrity and Public Confidence in a Time of Crisis. JAMA 2020; 323(19):1899-1900.. Entretanto, no final de março, cerca de três meses após o início da pandemia, Laestadius et al.8080 Laestadius L, Wang Y, Ben Taleb Z, Kalan ME, Cho Y, Manganello J. Online National Health Agency Mask Guidance for the Public in Light of COVID-19: Content Analysis. JMIR Public Health Surveill 2020; 6(2):e19501 avaliaram as diretrizes e informações acerca do uso de máscaras em sites oficiais de agências e ministérios de saúde de 25 países e reportaram a falta de sistematização e alinhamento das informações prestadas à população.
O primeiro país a decretar a obrigatoriedade do uso de máscaras em locais públicos foi a Mongólia, em 14 de março, sucedido pelo Vietnã, Venezuela e República Tcheca133133 Masks4All. Quais países exigem máscaras em público ou recomendam máscaras? [Internet]. [acessado 2020 Jul 11]. Disponível em: https://masks4all.co/pt/what-countries-require-masks-in-public/
https://masks4all.co/pt/what-countries-r...
(Tabela 1). Até o dia 13 de julho de 2020, seis meses após o início da pandemia, 129 países haviam passado a recomendar o amplo uso de máscaras em locais públicos, de forma geral ou mais restritiva. Em outros 17 países, a obrigatoriedade foi adotada em parte do território (municípios/estados)133133 Masks4All. Quais países exigem máscaras em público ou recomendam máscaras? [Internet]. [acessado 2020 Jul 11]. Disponível em: https://masks4all.co/pt/what-countries-require-masks-in-public/
https://masks4all.co/pt/what-countries-r...
. Ou seja, dos 193 países considerados Estados soberanos, até o dia 13 de Julho, 146 já se posicionavam favoravelmente ao uso de máscaras como medida preventiva à disseminação da COVID-19, destacando a relevância desta do ponto de vista de saúde pública (Figura 4). Para Li et al.8989 Li DTS, Samaranayake LP, Leung YY, Neelakantan P. Facial protection in the era of COVID-19: A narrative review. Oral Dis 2020; 10.1111/odi.13460.
https://doi.org/10.1111/odi.13460...
, a eficácia da obrigatoriedade do amplo uso de máscaras é uma das grandes lições desta pandemia. Atualmente, as máscaras são consideradas capazes de reduzir a gravidade da COVID-19, e possibilitar que as novas infecções sejam assintomáticas134134 Gandhi M, Rutherford GW. Facial Masking for Covid-19 - Potential for 'Variolation' as We Await a Vaccine. N Engl J Med 2020; 383(18):e101..
Alguns países recomendaram o uso de máscaras no início da pandemia mesmo na ausência de evidências científicas consolidadas sobre a capacidade da medida de reduzir o seu ritmo de expansão da pandemia8181 Majeed A, Seo Y, Heo K, Lee D. Can the UK emulate the South Korean approach to covid-19? BMJ 2020; 369:m2084., possivelmente pautados pelo princípio da precaução - definido como uma estratégia para abordar questões de dano potencial, quando falta um amplo conhecimento científico sobre o assunto. Segundo Greenhalgh et al.3636 Greenhalgh T, Schmid MB, Czypionka T, Bassler D, Gruer L. Face masks for the public during the covid-19 crisis. BMJ 2020; 369:m1435., é necessário aplicar este princípio diante de questões de relevância para a proteção da saúde da população, principalmente quando análises de custo-benefício indicam poucos efeitos adversos potenciais e a possibilidade de alcançar benefícios significativos135135 Brooks JT, Butler JC, Redfield RR. Universal Masking to Prevent SARS-CoV-2 Transmission-The Time Is Now. JAMA 2020; 10.1001/jama.2020.13107.

.
Os efeitos benéficos da adoção precoce das máscaras de tecido por alguns países ficaram evidentes em estudos que comparam o avançar da COVID-19 em diferentes regiões e em estudos que realizaram rastreamento de casos de infecção por SARS-CoV2. Um estudo transnacional comparou, por exemplo, a evolução da pandemia na Áustria e República Tcheca, sugerindo a eficácia do uso de máscaras no combate à COVID-19128128 Howard J, Huang A, Li Z, Tufekci Z, Zdimal V, van der Westhuizen H, von Delft A, Price A, Fridman L, Tang L, Tan V, Watson GL, Bax CE, Shaikh R, Questier F, Hernandez D, Chu LF, Ramirez CM, Rimoin AW.

https://doi.org/10.20944/preprints202004...
. Ambos os países estabeleceram requisitos de distanciamento social na mesma data, mas somente a República Tcheca incorporou, ao mesmo tempo, o uso obrigatório de máscaras. A partir daí, observou-se trajetória ascendente no número de infectados pelo coronavírus na Áustria, enquanto a curva epidêmica da República Tcheca manteve-se longa e plana. Apenas quando a Áustria também determinou por decreto governamental o uso de máscaras, os dois países voltaram a ter trajetórias similares128128 Howard J, Huang A, Li Z, Tufekci Z, Zdimal V, van der Westhuizen H, von Delft A, Price A, Fridman L, Tang L, Tan V, Watson GL, Bax CE, Shaikh R, Questier F, Hernandez D, Chu LF, Ramirez CM, Rimoin AW.

De forma similar, Cheng et al.4040 Cheng KK, Lam TH, Leung CC. Wearing face masks in the community during the COVID-19 pandemic: altruism and solidarity. Lancet 2020; S0140-6736(20)30918-1 . compararam a evolução da incidência de COVID-19 em Hong Kong com a evolução da doença em outros oito países, e atribuíram a baixa taxa de contaminação em Hong Kong à adoção universal e voluntária do uso de máscaras pela maioria da população (96,6% durante o estudo) no início da pandemia. Este mesmo estudo rastreou algumas rotas de transmissão entre os primeiros 961 casos reportados em Hong Kong, identificando que onze núcleos de infecção de 113 pacientes ocorreram em espaços de lazer sem uso de máscaras, incluindo restaurantes, karaokês e academias de ginástica, e que apenas três núcleos ocorreram em locais de trabalho onde o uso de máscaras era praticado5353 Cheng VCC, Wong S-C, Chuang VWM, So SY-C, Chen JH-K, Sridhar S, To KK-W, Chan JF-W, Hung IF-N, Ho P-L, Yuen K-Y. The role of community-wide wearing of face mask for control of coronavirus disease 2019 (COVID-19) epidemic due to SARS-CoV-2. J Infect 2020; 81(1):107-114.. Outros estudos epidemiológicos que rastrearam rotas de infecção e transmissão também concluíram que a taxa de transmissão foi menor em situações nas quais as máscaras foram utilizadas3131 Liu X, Zhang S. COVID-19: Face masks and human-to-human transmission. Influenza Other Respi Viruses 2020; 14(4):472-473 .,7575 Gao Q, Hu Y, Dai Z, Xiao F, Wang J, Wu J.

A partir de dados sobre a evolução da pandemia na Itália e em Nova Iorque, ambos severamente atingidos pela COVID-19, Zhang et al.9393 Zhang R, Li Y, Zhang AL, Wang Y, Molina MJ. Identifying airborne transmission as the dominant route for the spread of COVID-19. Proc Natl Acad Sci USA 2020; 117(26):14857-14863. apontam que a obrigatoriedade de cobertura das vias respiratórias evitou mais de 76 mil e 66 mil novos casos de infecção pelo novo coronavírus, respectivamente9393 Zhang R, Li Y, Zhang AL, Wang Y, Molina MJ. Identifying airborne transmission as the dominant route for the spread of COVID-19. Proc Natl Acad Sci USA 2020; 117(26):14857-14863.. As medidas que tornaram compulsório o uso de máscaras de tecido em ambientes públicos nos estados de Nova Iorque e Washington foram adotadas após modelos de predição indicarem que a adoção massiva de máscaras, mesmo as menos eficazes, poderia reduzir a transmissão do novo coronavírus colaborando para o achatamento da curva epidêmica e dos picos de letalidade4646 Eikenberry SE, Mancuso M, Iboi E, Phan T, Eikenberry K, Kuang Y, Kostelich E, Gumel AB.

Mathematical assessment of the impact of non-pharmaceutical interventions on curtailing the 2019 novel Coronavirus. Math Biosci 2020; 325:108364.. Outros estudos afirmam que a recomendação de manter a distância de dois metros quando em local público só é eficaz se a medida for associada ao uso de máscaras5252 Setti L, Passarini F, De Gennaro G, Barbieri P, Perrone MG, Borelli M, Palmisani J, Di Gilio A, Piscitelli P, Miani A.

Influence of wind and relative humidity on the social distancing effectiveness to prevent COVID-19 airborne transmission: A numerical study. J Aerosol Sci 2020; 105585.. Alguns estudos sugerem que a pandemia de COVID-19 poderia ser contida se a maioria ou de preferência todas as pessoas usassem máscaras de tecido em locais públicos2121 Feng S, Shen C, Xia N, Song W, Fan M, Cowling BJ.

compararam o uso de máscaras à imunidade de rebanho obtida com vacinas, visto que quanto mais as pessoas aderem a essa medida preventiva em público (onde o distanciamento social recomendado não é possível), maior é a proteção da comunidade135135 Brooks JT, Butler JC, Redfield RR.

. Os mesmos autores afirmaram que a proteção em nível comunitário proporcionada pelo uso de máscaras de tecido pode reduzir o número de novas infecções e intervenções municipais mais perturbadoras da sociedade, como o fechamento do comércio e o lockdown - a política pública que exige que os cidadãos permaneçam em casa.
Ainda que diversos estudos indiquem a eficácia das máscaras no controle da pandemia e que um número crescente de países exija o uso das máscaras de tecido em ambientes extradomiciliares, a taxa de adesão pelas populações varia expressivamente. Certamente, a recomendação das autoridades sanitárias pelo uso de máscaras influencia o comportamento da população, conforme indica um estudo (ainda em preprint) realizado nos EUA que relata um aumento de 12% no uso de máscaras entre os americanos em apenas cinco dias após o anúncio do CDC137137 Goldberg MH, Gustafson A, Maibach EW, Ballew MT, Bergquist P, Kotcher JE, Marlon JR, Rosenthal SA, Leiserowitz A. Mask-wearing increases after a government recommendation: A natural experiment in the U.S. during the COVID-19 pandemic. Front Commun 2020; 5(44):1-6.. Todavia, entre os estudos incluídos nessa narrativa, as maiores taxas de aderência ao uso de máscaras são de países asiáticos com histórico de uso desse recurso no controle de outras doenças infecciosas respiratórias e poluição do ar4242 Cowling BJ, Ali ST, Ng TWY, Tsang TK, Li JCM, Fong MW, Liao Q, Kwan MY, Lee SL, Chiu SS, Wu JT, Wu P, Leung GM.

As populações da Coreia do Sul e de Singapura, por exemplo, já vinham utilizando máscaras em público, especialmente depois do surto de SARS em 2003, o que facilitou a transposição da medida no cenário de pandemia pelo vírus SARS-CoV-2. Na Coreia do Sul, ainda no início da pandemia, mais de 60% da população já utilizava máscaras5050 Lee M, You M. Psychological and Behavioral Responses in South Korea During the Early Stages of Coronavirus Disease 2019 (COVID-19). Int J Environ Res Public Health 2020; 17(9):2977.. Em Hong Kong, o uso de máscaras em ambientes extradomiciliares saltou de 74,5% para 98,8% entre os entrevistados, entre janeiro e março de 20204242 Cowling BJ, Ali ST, Ng TWY, Tsang TK, Li JCM, Fong MW, Liao Q, Kwan MY, Lee SL, Chiu SS, Wu JT, Wu P, Leung GM.

A efetividade do uso das máscaras de tecido para o controle da COVID-19 é bem suportada pela literatura quando em conjunto com outras medidas de combate à pandemia como a higienização correta das mãos e o distanciamento social8686 Chu DK, Akl EA, Duda S, Solo K, Yaacoub S, Schünemann HJ, COVID-19 Systematic Urgent Review Group Effort (SURGE) study authors.

O uso das máscaras de tecido sem a adoção destas outras medidas não pode, entretanto, ser interpretado pelos usuários como solução para a crise sanitária, visto que sua eficácia, quando descumpridas outras recomendações, é ainda um tema controverso6060 MacIntyre CR, Chughtai AA.

Evidências sobre o uso de máscaras na prevenção da COVID-19 no Brasil
A avaliação dos padrões de buscas online no Brasil evidenciou um pico no interesse sobre o coronavírus no país no dia 21 de março, e um interesse expressivo da população brasileira acerca do uso de máscaras logo após a publicação da recomendação do MS115115 Filho C, Vieira LJES, Silva RM. Buscas na internet sobre medidas de enfrentamento à COVID-19 no Brasil: descrição de pesquisas realizadas nos primeiros 100 dias de 2020. Epidemiol Serv Saúde 2020; 29(3):e2020191..
Os dois primeiros estados brasileiros a decretarem oficialmente a obrigatoriedade do uso de máscaras em ambientes extradomiciliares como medida adicional de combate à pandemia foram Pará e Santa Catarina, em 16 de abril, seguidos por Minas Gerais, Amapá e Goiás88 Brasil. Ministério da Saúde (MS). Nota Técnica: Uso de máscaras caseiras. Brasília: MS; 2020. (Tabela 2). Já assoladas pela pandemia, as capitais Manaus e Rio de Janeiro fizeram o mesmo em 14/04 e 18/04, respectivamente. A Figura 5 ilustra os estados brasileiros de acordo com o mês em que foi decretado oficialmente o uso obrigatório de máscaras em ambiente extradomiciliar.
Estados brasileiros que sancionaram leis estabelecendo o uso mandatório de máscaras em ambientes extradomiciliares por mês de decreto oficialmente publicado.
Em nível federal, o Projeto de Lei (PL 1.562/2020), que determinava o uso obrigatório de máscaras em locais públicos ou locais privados acessíveis ao público em todo o território nacional enquanto durasse o estado de calamidade pública decorrente da pandemia, foi aprovado pelo Plenário da Câmara dos Deputados em 9 de junho, e seguiu para sanção presidencial139139 Senado Federal.

. Porém, o presidente só sancionou a Lei nº 14.019 no dia 2 de julho de 2020140140 Brasil. Lei nº 14.019, de 2 de julho de 2020. Altera a Lei nº 13.979, de 6 de fevereiro de 2020, para dispor sobre a obrigatoriedade do uso de máscaras de proteção individual para circulação em espaços públicos e privados acessíveis ao público, em vias públicas e em transportes públicos, sobre a adoção de medidas de assepsia de locais de acesso público, inclusive transportes públicos, e sobre a disponibilização de produtos saneantes aos usuários durante a vigência das medidas para enfrentamento da emergência de saúde pública de importância internacional decorrente da pandemia da Covid-19. Diário Oficial da União 2020; 8 set., quando todos os estados brasileiros, exceto o Rio de Janeiro, já exigiam o uso de máscaras em ambientes extradomiciliares. Além disso, o presidente vetou importantes partes do PL, como o uso das máscaras em órgãos e entidades públicas e em estabelecimentos comerciais, industriais, templos religiosos, instituições de ensino e demais locais fechados em que haja aglomeração de pessoas. A Presidência também excluiu da proposta dispositivo que agravava a punição para infratores reincidentes ou que deixassem de usar máscara em ambientes fechados139139 Senado Federal. Bolsonaro veta uso obrigatório de máscara no comércio, em escolas e em igrejas [Internet]. Senado Notícias; 2020 [acessado 2020 Jul 11].

. De acordo com o texto sancionado, os estabelecimentos também não serão obrigados a fornecer máscaras gratuitamente aos funcionários, e o poder público não será obrigado a fornecer o material a populações em situação de vulnerabilidade socioeconômica, conforme previsto pelo PL. É importante salientar que o fornecimento de máscaras a populações vulneráveis ou mesmo a toda a população de cidades ou regiões já é uma medida adotada pelos governos de outras nações6666 Parry J. Covid-19: Hong Kong government supplies reusable face masks to all residents. BMJ 2020; 369:m1880. e em alguns estados brasileiros, a exemplo da Bahia. Por esse e outros motivos, o governo brasileiro se tornou uma referência de como não proceder durante uma crise sanitária.
O uso das máscaras de tecido como uma medida adicional de proteção frente à pandemia de COVID-19 é especialmente relevante para populações em vulnerabilidade social diante da impossibilidade de adoção de medidas de distanciamento social em diversos contextos brasileiros, a exemplo das periferias e favelas e dos transportes públicos3434 Zhou Z-G, Yue D-S, Mu C-L, Zhang L.

Face mask use in the general population and optimal resource allocation during the COVID-19 pandemic. Nat Commun 2020; 11(1):4049.. Por outro lado, ressaltamos também a necessidade de considerar os potenciais efeitos da adoção desta medida protetiva para alguns segmentos da população, como quando aplicados recortes sociais para grupos etários e étnico-raciais. Especificamente, alertamos para a possibilidade de que o amplo uso de máscaras pela população negra exponha este grupo social a um maior assédio pela polícia e a situações de preconceito e injúria racial141141 CNN.

Discussão
Esta síntese narrativa mostra a rápida evolução do conhecimento e a mudança de percepção a respeito desta medida de controle adicional à transmissão do SARS-CoV-2, revelando não apenas a contribuição científica prolífera e profusa em meio à pandemia, mas também como a COVID-19 tem desafiado os limites do conhecimento. O grande número de artigos publicados diariamente e a baixa qualidade de artigos envolvendo a temática, bem como a ausência de estudos observacionais sobre o uso correto das máscaras, revelam os principais desafios de se produzir revisões de forma mais oportuna em um momento onde a produção tem crescido exponencialmente.
Diante da evolução da pandemia e das evidências acumuladas nos últimos meses, a recomendação do amplo uso de máscaras de tecido em público se destaca como uma importante estratégia para: i) reduzir a propagação do novo coronavírus2626 Leung CC, Lam TH, Cheng KK.

Dessa forma, a ampla adoção de máscaras de tecido pode ser vista também como um exemplo de dever cívico. Trata-se de um pequeno esforço e uma solução de baixa tecnologia altamente eficaz e capaz de mudar a trajetória epidemiológica dos países, favorecendo os esforços nacionais e globais contra a COVID-19135135 Brooks JT, Butler JC, Redfield RR. Universal Masking to Prevent SARS-CoV-2 Transmission-The Time Is Now. JAMA 2020; 10.1001/jama.2020.13107.
https://doi.org/10.1001/jama.2020.13107...
.
Essa revisão da literatura nos permitiu avaliar a nível nacional e internacional a relevância do uso de máscaras de tecido como medida adicional de proteção à transmissão do SARS-CoV-2. Apesar do seu escopo, essa revisão apresenta algumas limitações: i) a revisão narrativa pode ser criticada por não apresentar uma estrutura rígida como a revisão sistemática e a integrativa, entretanto, apresenta-se como uma alternativa adequada para identificar lacunas, explorar de forma crítica o tema ainda pouco conhecido144144 Jesson J, Matheson L, Lacey FM. Doing Your Literature Review: Traditional and Systematic Techniques. Thousand Oaks: Sage Publications; 2011., além de ser realizada num tempo mais curto, a fim de contemplar a urgência de respostas visando o controle da pandemia; e ii) a inclusão de artigos em fase de pré-publicação (base MedRxiv) que ainda não passaram pela revisão por pares e podem ter sua qualidade questionada, porém isso se justifica pelo propósito de produzir evidências que deem suporte para recomendações para o controle da pandemia.
As evidências acumuladas nos poucos meses da epidemia fortalecem a ideia de que o amplo uso de máscaras de tecido em ambientes extradomiciliares é uma intervenção de saúde pública promissora que, associada às medidas preventivas de distanciamento social e de higienização das mãos, contribui para a redução da velocidade de disseminação da COVID-19, reduzindo o número de casos e óbitos. Estas evidências foram rapidamente absorvidas para políticas públicas, na medida em que um número crescente de países vem adotando a obrigatoriedade do seu uso em locais públicos. Um estudo realizado na Alemanha mostrou que o uso de máscaras pela população foi percebido como um contrato social e a política de uso obrigatório das mesmas é mais justa que a política de uso voluntário145145 Betsch C, Korn L, Sprengholz P, Felgendreff L, Eitze S, Schmid P, Böhm R. Social and behavioral consequences of mask policies during the COVID-19 pandemic. Proc Natl Acad Sci USA 2020; 117(36):21851-21853.. Muitos entenderam que as evidências existentes fornecem elementos suficientes para ação baseada no princípio da precaução. Neste caso específico, trata-se de uma intervenção que tem o potencial de ter alta efetividade com baixo risco de efeitos adversos146146 Greenhalgh T. Face coverings for the public: Laying straw men to rest. J Eval Clin Pract 2020; 26(4):1070-1077..
No Brasil, onde vivenciamos a escassez de máscaras descartáveis, a reduzida capacidade de testagem e triagem de casos suspeitos e a existência de grandes adensamentos urbanos, muitos deles com moradias sem acesso a água e com elevada aglomeração intradomiciliar, o uso de máscaras de tecido pode ser ainda mais relevante no combate à propagação da doença. Seu uso se torna essencial sobretudo diante da flexibilização das medidas de distanciamento social e da implantação de estratégias para o retorno gradual às atividades4040 Cheng KK, Lam TH, Leung CC. Wearing face masks in the community during the COVID-19 pandemic: altruism and solidarity. Lancet 2020; S0140-6736(20)30918-1 .,4747 Thomson GA.

, que já começam a ser discutidas e realizadas por gestores públicos, apesar do contínuo agravamento da pandemia no país. As previsões atuais dos cenários pós-pandemia sugerem que o uso de máscaras de tecido em ambientes extradomiciliares será uma medida importante na desaceleração de uma possível segunda onda de contágio6161 Hoertel N, Blachier M, Blanco C, Olfson M, Massetti M, Rico MS, Limosin F, Leleu H. Lockdown exit strategies and risk of a second epidemic peak: a stochastic agent-based model of SARS-CoV-2 epidemic in France. medRxiv 2020; 10.1101/2020.04.30.20086264.

,7878 Goscé L, Phillips PA, Spinola P, Gupta DRK, Abubakar PI. Modelling SARS-COV2 Spread in London: Approaches to Lift the Lockdown. J Infect 2020; 81(2):260-265.. Ademais, cabem também ações educativas que promovam o uso correto de máscaras de tecido como uma nova norma social3535 Javid B, Weekes MP, Matheson NJ. Covid-19: should the public wear face masks? BMJ 2020; 369:m1442.,9090 Goh Y, Tan BYQ, Bhartendu C, Ong JJY, Sharma VK. The face mask: How a real protection becomes a psychological symbol during Covid-19? Brain Behav Immun 2020; 88:1-5..
Assim, são necessárias ações conjuntas entre as esferas do poder público no intuito de: i) apoiar ou desenvolver estratégias que possibilitem o aumento da produção e distribuição do produto à população, inclusive para doação aos grupos mais vulneráveis e com menos recursos, assim como sua comercialização em estabelecimentos comerciais que tenham permissão para seguirem abertos no período de pandemia; ii) incentivar e fomentar a produção caseira e a confecção de máscaras de tecido por costureiras autônomas, assegurando-lhes condições dignas de trabalho, remuneração e proteção à saúde; e iii) assegurar que grupos raciais ou socioeconomicamente desfavorecidos não sejam estigmatizados com a adoção de medidas compulsórias de uso de máscaras em ambientes extradomiciliares.
Conclusão
A ampla adesão ao uso de máscaras de tecido em ambientes extradomiciliares é uma intervenção eficaz que, em conjunto ao distanciamento social e higienização correta das mãos, tem sido adotada, em maior ou menor escala, por todos os continentes com o avançar da pandemia por contribuir com a redução da velocidade de transmissão do SARS-CoV-2.
Por fim, representam uma alternativa mais econômica, logisticamente viável e acessível para a população, além de ser ambientalmente sustentável e colaborar para a manutenção dos estoques das máscaras profissionais.
