Britain is not seeing an acceleration in the number of cases of COVID-19 but it is too early to tell whether the coronavirus outbreak is peaking, the government's Chief Scientific Adviser Patrick Vallance said on Tuesday. 'There is a fairly steady increase in numbers. It's possible we are beginning to see the beginning of change, in terms of the curve flattening a little bit. We won't know that for sure for a week or so,' Vallance said at a news conference. 'But what we're not seeing is an acceleration.'
