A “traffic light” system advising the public about the risks of different activities could be used to ease lockdown, the Government’s scientific advisors have said. Laura Donnelly writes in The Telegraph that the proposals, drawn up last month, suggest lockdown restrictions should be eased “very gradually” and warn against relaxing the rules for workers without allowing social activities to resume. The paper was drawn up by the scientific pandemic influenza group on behavior (SPI-B), and considered by the scientific advisory group for emergencies (Sage) at its 2 April meeting. It warns that the abrupt lifting of restrictions and any subsequent increase in infections could undermine public trust in health policy, and mean people are less likely to comply with future demands. The documents are among 17 papers submitted to Sage in recent weeks, for consideration by the scientists who advise Government.
