The news: Keeping people two meters apart from each other is far more effective than just one at reducing the risk of spreading coronavirus, according to a new analysis in The Lancet. The researchers combed through 172 observational studies across 16 countries and then applied statistical analysis to pull out estimates of infection risk. The models they used on nine key studies found that the transmission risk when people stood at least one meter away was an average of around 3%, but rose to about 13% when people were standing within one meter. The risk of transmission roughly halves for every extra meter of distancing up to three meters, the modeling suggested.
