Documents reveal ministers' advice to ministers in the context of rising coronavirus incidence.
Experts stated tighter efforts are needed to regulate Omicron and prevent daily hospitalisations approaching 3,000, according to papers from a Sage conference on Thursday.
Indoor mixing is the ‘biggest risk factor' for the propagation of the Omicron variety, they say.
Reduce group numbers, increase physical distance, reduce contact time and close high-risk locations are all mentioned in the meeting minutes.
For example, if one person in a home or group tests positive before attending an event, the complete group should not go — even if they did not test positive.
Even if transmission is ‘slowed immediately', hospitalisations might reach ‘1,000-2,000 per day in England before the end of the year'.
They also said that without new measures, hospital admissions could reach 3,000 per day in the spring.
Increased booster programme enrollment will not help, as many of those admitted will already be infected.
While they acknowledged there were numerous ‘uncertainties,' their forecasts are bleak.
Official SPI-M-O (Scientific Pandemic Influenza Group on Modelling) documentation were also released on December 8th.
In almost all cases, ‘a major reduction in transmission (akin to the nationwide lockdown established in January 2021 and the pingdemic in July 2021) is required'.
The UK Health Security Agency (UKHSA) reported an increase in the number of Omicron-associated deaths in England from one to seven.
In England, 85 persons with Omicron were hospitalised, up from 65.
The UKHSA reported 10,059 new confirmed cases of Covid-19 Omicron in the UK.
The UK now has 24,968 confirmed occurrences of the variation.
Officials reportedly planned a two-week circuit breaker lockout following Christmas.
Many argue that this is not soon enough to avoid hospitalizations from overwhelming the NHS.
The Liberal Democrats want Parliament to reconvene on Monday to discuss future measures.
Mr Davey said Boris Johnson had reacted too late, wasted opportunities and refused to act when scientists warned him to.
‘We cannot allow the Prime Minister to do nothing as the NHS and businesses crumble.
The ministers must convey the latest scientific advice to MPs and ensure a proper debate on future Covid measures, including support for businesses in this increasingly tough period.
According to Stephen Reicher, a social psychologist at the University of St Andrews and a Sage member, Plan B remedies alone would not be adequate to stem the tide of instances.
He told Times Radio that now was the moment to act.
‘All science shows that (Plan B) won't be enough,' said Prof Reicher.
‘The only solution, or at least the most effective approach, is to reduce the amount of connections we have,' he continued.
‘Having a circuit-breaker is often the most effective technique of reducing touch.
‘You could have it after Christmas, but by then it would be too late, we would have had a tremendous rise of infections, with all the societal implications.'
‘When people say ‘look, we don't want to close', we agree. However, due to the spread of sickness, things are closing down. Acting now, I believe.'
However, Lord Victor Adebowale, chairman of the NHS Confederation, cautioned that prudence should be exercised.
On Saturday, Cabinet ministers were updated on the Omicron issue.
No Cabinet meeting or further discussion was held, but ministers were updated on the data around the variant.
While the devolved nations will meet with Cobra over the weekend.
As of 9am Saturday, the UK has 90,418 lab-confirmed Covid-19 cases.
After testing positive for Covid-19, 125 more persons died.
‘The Government will continue to closely monitor all new evidence and will consider our measures as we learn more about this variety,' a statement said.
