[*Note from HIFA moderator (Neil PW): I was unable to find evidence that cloth masks are effective against coronavirus. The only peer-reviewed paper I could find was this (in relation to flu and other infections among health workers): 'A cluster randomised trial of cloth masks compared with medical masks in healthcare workers. 2015. Results The rates of all infection outcomes were highest in the cloth mask arm... This study is the first RCT of cloth masks, and the results caution against the use of cloth masks.' https://bmjopen.bmj.com/content/5/4/e006577 ]
