The two-metre physical distancing rule to curb the spread of coronavirus is based on “outdated science,” a group of academics have said.
Instead of a one-size-fits-all approach, there should be “graded recommendations” for different distancing rules in different settings, they argued.
Writing in The BMJ, the team of researchers said this would provider greater protection for people in high risk settings and greater freedoms for people in lower risk settings.
They added that this would “potentially enable a return towards normality in some aspects of social and economic life”.
Distancing rules should take account of multiple factors that affect risk, including type of activity, indoor versus outdoor settings, level of ventilation and whether face coverings are worn, they said.
