Britain’s two metre social distancing rule is based on outdated science and is not far enough in crowded places like bars, experts say. Dr Nicholas Jones and colleagues at the University of Oxford said the rule was produced from studies dating back up to 100 years ago and is too simplistic. Instead, there should be a grading system depending on how ‘risky’ a place is, they said. Evidence suggests that how far virus-carrying droplets can spread from a cough or sneeze depends on the environment around them. A bar, pub or nightclub would be deemed high risk because it is indoors, poorly ventilated and people have to shout to be heard over music. Therefore it should have more stringent distancing rules, the researchers argued. But in places deemed to be low risk such as parks, the rules can afford to be relaxed, which would ’potentially enable a return towards normality in some aspects of social and economic life’. Scientists have previously argued the two-metre (6’7″) rule is not based on evidence but, in contrast to Dr Jones, were in favour of scrapping it. Britons are told to distance themselves two metres from others, but in England and Northern Ireland this was… Read full this story
