Efficacy of cloth face masks for the prevention of COVID-19 transmission Rapid review questions Do cloth face masks help prevent the spread of COVID-19? In brief:
- Face masks are used to protect wearers from infection and to prevent the spread from people with COVID-19, particularly those who are pre-symptomatic.
- The World Health Organisation on 5 June 2020 updated its guidance advising that to prevent COVID-19 transmission effectively in areas of community transmission, governments should encourage the public to wear masks
- A systematic review in healthcare and non-healthcare settings showed that face mask use could result in a large reduction in risk of infection, with stronger associations with N95 or similar respirators compared with disposable surgical masks or similar.
- A pre peer review rapid systematic review of three randomised controlled trials showed that wearing a face mask may slightly reduce the odds of developing respiratory symptoms by 6%.
- In the same review, the protective effect was very small if only one person, the infected person or well person wore the mask, however this was based on very low-quality evidence.
- A review reflecting on influenza epidemics found some efficacy of masks if worn by those with respiratory systems but not if worn by asymptomatic individuals.
- There are concerns masks are associated with over-estimation of the extent of protection afforded and non-compliance with other effective measures, such as hand washing, social distancing, and home isolation.
- Evidence from health care settings suggest cloth masks can be a source of infection.
- Recommendations on face mask use in community settings varies by country, some experts support their use based on the precautionary principle
