Exclusive: Health and Security Agency advice comes amid concerns that plan B measures will not stop spread of Omicron
Senior health officials have drawn up advice saying the UK should bring back stricter isolation and testing rules for contacts of Covid cases, amid concerns that triggering plan B involving working from home and vaccine passports is not enough to stop the spread of Omicron.
Top officials at the UK Health and Security Agency have given three different options to help contain the threat, which at the strictest end would mean all contacts of Covid cases being asked to isolate again regardless of age or vaccination status. The alternatives would be asking contacts of positive Covid tests to isolate until a PCR test result, with subsequent daily lateral flows, or requiring the contacts to take daily lateral flows. They give further advice in favour of a return to working from home and an extension of mandatory mask wearing.
