From this afternoon's govt update
Paul Brand from ITV News asks England's deputy chief medical officer Dr Jenny Harries if current measures in place will continue beyond three weeks. She points out the UK has only had one week of the measure and that the prime minister said the situation would be "reviewed" after the three weeks.But she adds it would be "quite dangerous" to then revert to normal life. "If we stop then all of our efforts will be wasted," she adds. She says that measures may be reduced gradually over time.
Dr Harries says it might be two or three months before we see the longer-term impact, and about three to six months before to see "at which point we can actually get back to normal. And it is plausible it could go further than that".
