Ministers should focus on indoor mixing - Sage scientist
Ministers met over the weekend to discuss how to enforce the current lockdown measures in England more strictly - and whether even tighter restrictions may be needed.
Lucy Yardley, a professor of health psychology at the Universities of Bristol and Southampton, said while there was more activity taking place now than during the first national lockdown in March, this was not necessarily because people were not obeying the rules.
"I think it’s more that people are being allowed to do more and so they are," she told BBC Radio 4's Today programme.
Asked what changes would make the biggest difference, Prof Yardley, who participates in the government's Scientific Advisory Group for Emergencies, said the focus should be on places where the virus spreads more easily - such as in the home, in educational settings and at work.
“I think the really important thing to realise is that not very much infection spreads outside the home at all so clamping down on people exercising outside is not likely to affect infection spread," she said.
“There’s a huge difference between indoors and outdoors - and as long as people keep their social distance that’s a much less risky situation."
