Dr Andrew Preston, reader in microbial pathogenesis at the University of Bath, said: “The situation is fast-moving and requires decisive decision-making. Today, the government has recognised that the situation is continuing to deteriorate in many areas and that tougher restrictions are required if the hope is to contain it.
“With cases rising so quickly, the delay of three critical days – with new tiering not taking effect until Boxing Day – will mean that by then case numbers are going to be much, much higher and as a result much, much more difficult to bring down. If containment is the focus, then unfortunately, the restrictions need to be immediate, despite the fallout this will cause.”
Before the announcement, Christina Pagel, professor of operational research at University College London, said waiting until Boxing Day to put more areas into tier 4 was too slow.
She told Times Radio: “We are in an incredibly dangerous situation … If we just wait and we let it spread to the north, where things are much more under control, then the whole country is on fire and I just feel like we have to stop it now and protect the north from the south, effectively.”
She added: “We’re constantly behind the curve. I think we have to put the whole country in tier 4 today, especially in those tier 2 areas around tier 4 that are just going through the roof. Why are we letting people mix at Christmas? You are just asking for trouble.”
