coronavirus, Scots researchers have found.Experts at Edinburgh University reassessed a model which predicted hundreds of thousands of deaths if no action was taken to stop the spread of Covid-19.They found that closing schools reduced the reproduction number of the virus but had the unexpected effect of increasing the number of deaths.The authors wrote in The BMJ: "In the absence of an effective vaccine for Covid-19, school closures would result in more overall deaths than no school closures."The new analysis revisited the piece of work by Professor Neil Ferguson and colleagues from Imperial College London.The Imperial study, also known as Report 9, prompted the far-reaching social restrictions implemented in March - including the closure.
