LONDON (Reuters) - New COVID-19 cases in England increased by around 51,900 each day last week, up nearly 50% on the week before, an official survey said on Friday, suggesting that the incidence of new infections was still rising steeply and had not levelled off. The ONS Infection Survey estimate was up from an estimated 35,200 new daily cases the week before, when the ONS had said there were signs of a levelling off in new infections. “The most recent modelled estimate shows the number of infections in England continues to increase steeply,” the Office for National Statistics (ONS) said. The ONS said 568,100 people had COVID-19 infections between 17 to 23 October, up from 433,300 the week before.
