COVID-19 cases 'growing exponentially' as professor warns government against repeating 'mistake' of acting too late

COVID infections appear to be 'growing exponentially', a professor has warned as he urged the government not to repeat the mistake of acting too late to tackle the spread of the virus. Sir Tim Gowers - whose argument against herd immunity helped trigger England's first lockdown last year - told Sky News that the recent increase in coronavirus cases 'worries me'. 'They seem to be multiplying by a certain fraction each day - in other words, growing exponentially,' he said.
