July 14, 2021 LONDON: The UK is unlikely to see a return to lockdowns and school suspensions even though winter will be “rough”, a Government scientific adviser has suggested. Calum Semple, a member of the Scientific Advisory Group for Emergencies (Sage) and professor of child health and outbreak medicine at the University of Liverpool, said he thought measures such as mask-wearing could be reintroduced over the winter to deal with a spike in Covid cases. It comes as a fellow Sage member, Professor Graham Medley, said mask-wearing “probably won’t do any good” unless it is mandatory, adding that the current Covid wave could last six weeks at its peak.
