戴口罩是否可以降低嚴重特殊傳染性肺炎傳播

Whether Wearing Masks can Reduce the Transmission of Coronavirus Disease 2019?

背景：台灣於2020年1月將嚴重特殊傳染性肺炎列為法定第五類傳染疾病，隨著疫情擴散，2021年5月國內宣布進入第三級警戒，中央流行疫情指揮中心強制進入公共場所須全程配戴口罩，期藉由實證探討「戴口罩是否可降低嚴重特殊傳染性肺炎傳播」，以提供民眾遵行之參考。
目的：希望藉由系統性文獻探討戴口罩是否可降低嚴重特殊傳染性肺炎傳播。
方法：以PICO擬定關鍵字，搜尋中英文電子資料庫，符合納入條件之研究，使用CASP評析工具進行文獻資料評價及精粹。
結果與結論：經由文獻篩選後共納入3篇系統性文獻回顧與統合分析文獻進行評讀，結果發現戴口罩確實可以降低嚴重特殊傳染性肺炎傳播，且未提及造成相關傷害事件，故可將此研究應用在對民眾推廣預防嚴重特殊傳染性肺炎傳播之衛教上。

Background: In January 2020, Taiwan added Coronavirus Disease 2019(COVID-19) as a statutory category 5 notifiable disease. As the epidemic spreads, the government announced that it has entered Level 3 COVID-19 alert in May 2021. The Central Epidemic Command Center maid it mandatory to wear masks at all times when entering public places. In order to provide reference for public concern, the author conducted an empirical study on 'whether wearing masks can reduce the transmission of Coronavirus Disease 2019'.
Purpose: To explore whether wearing masks can reduce the transmission of Coronavirus Disease 2019 by evidencebased medicine methods.
Methods: PICO was used to formulate keywords, and the Chinese and English electronic databases were searched , and CASP checklist was used to evaluate and summarize the literature.
Results and Conclusion: A total of 3 systematic reviews and meta-analyses of literature were collected through literature screening for evaluation. It was found that wearing masks can reduce the transmission of Coronavirus Disease 2019, and the literature did not mention the harm of wearing masks. Therefore, this study can be applied to promote public health education to prevent the transmission of Coronavirus Disease 2019.
