People could be given Covid-19 risk scores to determine how much they should move around as the country eases out of lockdown, a scientist has said.
A more subtle approach will be needed going forward as restrictions are eased, Professor Sir David Spiegelhalter said.
Scores could take into account factors such as age, gender, ethnicity and health conditions, he said.
Sir David, who is chairman of the Winton Centre for Risk and Evidence Communication at the University of Cambridge, said groups could be broken up into “more finely grained strata covering the whole range of risk”.
He told BBC Radio Four’s Today programme: “And that means I think we’re going to need some sort of individualised Covid risk score that can be used in that way, to group people according to their risk, and then that would be advisory, and if people wanted to move, and they protected other people, then that would be open to them.
“To have something that’s more standardised and that was common across the population, I think, would be a big advance.”
