According to the report published by the 'Academy of Medical Sciences, this second peak could be more severe than the first, with a reproduction rate R0 dropping to 1.7 from September. For comparison, the R0 in the UK currently ranges from 0.7 to 0.9. The 37 scientists and academics behind the report said the peak is expected to cause between 24,500 and 251,000 coronavirus-related deaths.
