There's no stopping the second wave of coronavirus, it seems, despite a bundle of new rules designed to do just that. Infection rates are rising rapidly, with estimates suggesting up to 100,000 people a day may be catching the virus. Across the Channel, France has admitted its regional approach is not working, by announcing a new national lockdown. Germany, to a lesser extent, is also planning one. Wales is in the middle of a short "fire-breaker" lockdown, in which bars, restaurants, churches and most shops have shut for a fortnight. So is a full-on UK-wide lockdown only a matter of time? The scientists certainly think so Many of those advising government have given it their backing. Sir Jeremy Farrar, a member of the Scientific Advisory Group for Emergencies (Sage), which advises ministers, says it should have happened already - and definitely needs to now. Any delay, he said, will be costly and will mean later restrictions will be "harder and longer". The tools we have at our disposal are not proving effective, said Dr Duncan Robertson, a disease modeller at Loughborough University. The test-and trace-system, designed to nip outbreaks in the bud, can't cope, he said. The service has consistently failed to reach enough close contacts of people who test positive. It's just a "matter of time" before a lockdown is introduced, he believes.
