The facemasks use has been discussed to prevent respiratory disease due airborne contamination. The aim of this study was to perform a systematic review about the face masks use to avoid airborne contamination during COVID-19 pandemic and related conditions, registered (PROSPERO-CRD42020198347) and performed according PRISMA.
PubMed, Embase and Scopus databases were used to collect data. Observational studies, published in 2020, and English language, were included. Two reviewers independently identified records through database search and reference screening and disagreements were resolved by a third reviewer. Six studies were included.
The works investigated about the use of masks (different types) to prevent droplets dissemination with virus or bacterial suspension and decrease COVID-19 transmission routes, comfort, or temperature. The studies have moderate to critical risk of bias and the level of evidence is III-2.
It is recommended facemask use to prevent droplets from escaping airborne and infecting other people, although there are different percentages of protection and can be possible a discomfort related the use. Further clinical trials to the effectiveness of face mask to avoid airborne contamination during the COVID-19 pandemic and the factors interfering with their effectiveness should be conducted.
关于使用口罩预防空气传播污染导致的呼吸道疾病已被讨论。本研究的目的是对在新冠疫情及相关情况下使用口罩避免空气传播污染进行系统评价，该评价已在国际前瞻性系统评价注册库（PROSPERO - CRD42020198347）注册，并按照系统评价和Meta分析的首选报告项目（PRISMA）进行。
使用PubMed、Embase和Scopus数据库收集数据。纳入2020年发表的英文观察性研究。两名评价者通过数据库检索和参考文献筛选独立识别记录，分歧由第三名评价者解决。共纳入六项研究。
这些研究调查了使用口罩（不同类型）预防病毒或细菌悬液飞沫传播、减少新冠病毒传播途径、舒适度或温度的情况。这些研究存在中度至高度偏倚风险，证据等级为III - 2。
建议使用口罩以防止飞沫通过空气传播并感染他人，尽管保护百分比不同，且使用口罩可能会带来不适。应针对新冠疫情期间口罩避免空气传播污染的有效性以及影响其有效性的因素开展进一步的临床试验。
