A new study provides the best available evidence for key ways of reducing SARS-CoV-2 transmission. A new meta-analysis, which brings together a significant amount of research on SARS-CoV-2 and related coronavirus protection, provides the best available evidence for physical distancing, mask use, and eye protection.
Until randomized controlled trials are conducted and can offer a greater degree of certainty, this study, which appears in The Lancet, provides doctors and policymakers with interim information on which to base key decisions.
Protective measures
The sudden, rapid emergence and spread of SARS-CoV-2 has left researchers searching for a safe, effective vaccine to reduce the transmission. However, the development of a vaccine may be 12–18 months away, if indeed such a vaccine can ever be found.
In the absence of a vaccine or other treatments that would slow the spread of the virus, public health organizations have recommended a series of social and behavioral changes to reduce the transmission. In addition to frequent handwashing, authorities have emphasized the importance of physical distancing: leaving the house less frequently and maintaining as much distance as possible from others at all times while outside.
They also recommend the use of face masks and eye protection, particularly among healthcare workers and people working in the community. However, experts are still debating when and how these policies should be implemented — including what constitutes the minimum distance that people should maintain from one another, when and where to wear personal protective equipment, and how effective this equipment is against the virus. ……..
