Scale of risks
Prof Ferguson stressed that models sent to the Government examined what the âpluses and minusesâ are of reopening, what additional data will be available at what point, and âwhat the scale of the potential risk isâ.
He added: âI mean, fundamentally, itâs for policymakers to take that on board.
âClearly you have to be more cautious if you want measures to be irreversibly changed and relaxed, but the Government will decide in the next few days.â
When asked whether a four-week delay in the road map could have a potential added advantage, due to schools being closed for summer holidays, Prof Ferguson said holidays would âreduce contacts in the population slightly and that will counterbalance any increase caused by going to step four [of the UK road map]â.
