Most studies were underpowered because of limited sample size, and some studies also reported suboptimal adherence in the face mask group.
In theory, transmission should be reduced the most if both infected members and other contacts wear masks, but compliance in uninfected close contacts could be a problem (12,34). Proper use of face masks is essential because improper use might increase the risk for transmission (39). Thus, education on the proper use and disposal of used face masks, including hand hygiene, is also needed.
篇文只係話未搵到證據，唔係話無用

Abstract
There were 3 influenza pandemics in the 20th century, and there has been 1 so far in the 21st century. Local, national, and international health authorities regularly update their plans for mitigating the next influenza pandemic in light of the latest available evidence on the effectiveness of various control measures in reducing transmission. Here, we review the evidence base on the effectiveness of nonpharmaceutical personal protective measures and environmental hygiene measures in nonhealthcare settings and discuss their potential inclusion in pandemic plans. Although mechanistic studies support the potential effect of hand hygiene or face masks, evidence from 14 randomized controlled trials of these measures did not support a substantial effect on transmission of laboratory-confirmed influenza. We similarly found limited evidence on the effectiveness of improved hygiene and environmental cleaning. We identified several major knowledge gaps requiring further research, most fundamentally an improved characterization of the modes of person-to-person transmission.

睇清楚啲先出post啦好心
你淨係quote人一個section無意思
首先篇文主要係做唔同措施對傳染病控制嘅meta analysis - 即係review其他studies
入邊有講其他measures例如洗手，咳同打乞嗤時遮口鼻。咁到底會唔會有interactive effects呢？篇文無研究過；只係分開討論每樣。如果有，你唔可以話口罩無撚用。用例子答你：如果會接觸到空氣病原情況下，你唔洗手捽眼口鼻戴P100都無用，反之亦然，你唔戴口罩但乜都唔掂一樣吸曬空氣病原體；而兩個interventions 夾埋又可能有第種效果[正正/負負/正負］。
正正因為可以有好多因素影響傳染程度，所以要注意篇文嘅研究方法係咪有效得出樓豬嘅結論。篇文口罩個部分只有十個研究做過，有啲係hall，有啲係household，先唔講上高提過其他感染控制措施，呢啲雜燴studies中有飛沬以外嘅傳染方式，而口罩係控制飛沬傳染，你自己諗下你沖涼時帶唔到口罩又同一屋簷下會點。作者都有提及sample size問題：Most studies were underpowered because of limited sample size, and some studies also reported suboptimal adherence in the face mask group.
所以，拉。

其實只係需要諗下:
個systematic review之中包括既文,sample size細,受測者adherence不足。
用一堆唔夠嚴謹既studies做systematic review,結果只會garbage in garbage out。
所以我覺得奇怪,點解咁既質素都出...

傳播途徑
流感病毒主要透過患者咳嗽、打噴嚏或說話時產生的飛沫傳播，亦可透過直接接觸患者的分泌物而傳播。
傳播途徑及潛伏期(武漢肺炎)
經呼吸道飛沫傳播是主要的傳播途徑，亦可通過接觸傳播。現時對潛伏期的估計大多是1到14天，最常見的是5天左右。

例如
你會對唔戴口罩既人有所警戒
社交上保持一定距離
飯前後，戴罩前後會洗手清毒
小左出街社交
呢樣野先係令個感染控制成功既關鍵
