According to a systematic review and meta-analysis of 172 observational studies published in The Lancet medical journal, measures such as social distancing and wearing face masks and eye protection are effective at reducing Covid-19 transmission.

There is a 12.8% chance of contracting the disease when physical distancing with less than 1 metre. This falls to just 2.6% with a distance of 1 metre or more.

According to The Lancet, the chance of transmission without masks and respirators is 17.4%. It falls to just 3.1% when they are worn. And whilst the chance of infection without any eye protection is 16%, it falls to 5.5% with it.
