Scientists warn that national lockdown needs to be stricter

The national lockdown needs to be toughened further to have a similar impact on case numbers as the March shutdown, scientists have said.

A more infectious variant, coupled with the usual winter pressures, requires stricter measures than the ones announced by Boris Johnson for England this month, the experts warned. Similar lockdown measures are in place across Scotland, Wales, and Northern Ireland.


Professor Robert West, a participant in the Scientific Pandemic Influenza Group on Behaviours (SPI-B), said the current restrictions are “still allowing a lot of activity which is spreading the virus”.

The professor of health psychology at University College London said that he and people he has spoken to – including epidemiologists, medical scientists, and virologists – think the rules should be tightened.

He told BBC News more children are going to school than in the first lockdown and that schools are “a very important seed of community infection”.

He added:

Because we have the more infectious variant, which is somewhere around 50% more infectious than last time round in March, that means that if we were to achieve the same result as we got in March we would have to have a stricter lockdown, and it’s not stricter.

It’s actually less strict.

Some scientists have estimated the variant could be as much as 70% more transmissible.


Susan Michie, professor of health psychology at University College London, said the current lockdown was “too lax”. The Scientific Advisory Group for Emergencies (Sage) member told BBC Radio 4’s Today programme:

It is definitely too lax, because if you think about it and compare ourselves with March, what do we have now? We have the winter season and the virus survives longer in the cold, plus people spend more time indoors and we know aerosol transmission, which happens indoors, is a very big source of transmission for this virus.

And secondly we have this new variant which is 50-70% more infectious. You put those two things together, alongside the NHS being in crisis, we should have a stricter rather than less strict lockdown than we had back in March.

Both she and Prof West are also part of Independent Sage, a group of experts who have argued for tougher measures at various points throughout the pandemic.


Prof West said the government is “very much aware of the consequences of different levels of restrictions and obviously what it’s doing is it’s making what it considers to be a political decision”.

Criticising the government, he said it is “completely false” for them to say they have acted at the right time. Asked if the level of infection and number of deaths was potentially avoidable, he told BBC News:

Yes, it was always avoidable. This is the really frustrating thing for all of us who work in public health.

This was always avoidable. When the Government says – I’m going to be quite critical now I’m afraid – but when the Government says ‘oh we’re in the same boat as other countries, we didn’t see this coming’, and so on, and ‘we’re acting at the right time’. That is completely false.

He said that in summer, when cases decreased, experts had advised the government to ramp up its Test and Trace system as well as support for people to isolate – but they failed to do so.

He said:

They didn’t do this. They maintained their hugely expensive but ineffective test, trace and isolate system. They’re not providing the kind of support that’s needed for people to feel that they’re able to do the sorts of things that the Government is now saying ‘well, we’re going to punish you if you don’t do it’. So they’ve got it all the wrong way round.

It’s really much, much more about support.

We know everyone is suffering under the Tories - but the Canary is a vital weapon in our fight back, and we need your support

The Canary Workers’ Co-op knows life is hard. The Tories are waging a class war against us we’re all having to fight. But like trade unions and community organising, truly independent working-class media is a vital weapon in our armoury.

The Canary doesn’t have the budget of the corporate media. In fact, our income is over 1,000 times less than the Guardian’s. What we do have is a radical agenda that disrupts power and amplifies marginalised communities. But we can only do this with our readers’ support.

So please, help us continue to spread messages of resistance and hope. Even the smallest donation would mean the world to us.
