A member of the UK government’s Scientific Advisory Group for Emergencies (Sage) says there is “nothing magical” about the two-metre rule in workplaces, as how long we spend close to other people is also key to avoiding infection.
The government’s first draft of its strategy to reopen workplaces, encourages employers to keep staff two metres apart – or if that’s not possible, to bring in extra hygiene procedures, physical screens and protective equipment.
Speaking about the two-metre rule on BBC Radio 4’s Today programme, Sir Jeremy Farrar said: “It’s based on old data about how far, when we cough and we sneeze, the droplets and the aerosols that may come from that spread.
“There’s nothing magical about two metres. Perhaps more important is the time you spend in contact with somebody else. Not just the distance but also the time.”
