The SAGE files: Government coronavirus reports reveal scientists said the UK’s outbreak will rumble on into 2021, banning sporting events has ‘imperceptible’ impact on infections and ‘bubbles’ of two households of any size could be next step

• A further 40 Government documents were released today by chief scientist 
• They show SAGE was told social distancing must continue for at least a year
• Government’s original ‘mitigation’ plan was based on deadly herd immunity
• Here’s how to help people impacted by Covid-19

Scientific reports presented to the Government have revealed that the UK’s Covid-19 will likely trundle on well into 2021 and social distancing must continue.

They also showed that scientists told officials banning people from going to large sporting events has an ‘imperceptible’ effect on the number of cases.

And the next step for social ‘bubbling’, currently allowed between a household of one-person and another home, could be to allow two houses of any size to join.

Some 40 documents were today published by the Government Office for Science, which is headed by Sir Patrick Vallance, England’s chief scientific adviser.

They are among dozens in a tranche of papers presented to SAGE, the Government’s Scientific Advisory Group for Emergencies, over recent months.

And the reports detail all the scientific advice which is being presented to decision-making officials who dictate when and how the country moves out of lockdown.

Files released today revealed scientists told the Government: 

• Schools should be closed for eight to 12 weeks for maximum effect and could flatten the peak of the crisis by 40 per cent, but only if timed right; 
• Banning people from going to large sporting events has an ‘imperceptible impact’ on the transmission of the coronavirus;
• The epidemic is likely to continue for a year or more because the UK’s society and economy could not cope with a lockdown tough enough to stop it dead;
• The Government’s original ‘mitigate’ plan was based on developing herd immunity – which Downing Street insists it wasn’t – and it wouldn’t have worked;
• World Health Organization warned social distancing ‘interventions’ must remain in place until at least 2021 to stop a resurgence of the virus; 
• Social bubbles could soon be extended to include two households of any size, and then two any-size families with a single household as a third member. 

A model presented to the Government in March showed that social distancing and lockdown measures may have to stay in place for more than a year (shown on bottom axis, more than 300 days) to stop Britain’s outbreak from spiralling out of control

Today’s batch of SAGE papers, which are now released in a bid for greater transparency from the Government, come as 202 more deaths have been confirmed.

There have now been a total of 41,481 people who died after testing positive for the coronavirus in the UK, but many more who weren’t tested or haven’t yet been counted.

Here, MailOnline takes a look at some of the stand-out papers from today:

Lockdown can delay peak of the outbreak but not stop it forever 

A strict, all-encompassing lockdown like the one the UK is now beginning to emerge from is an effective way to slow down a virus but cannot stop it forever, scientists said.

In an undated paper, experts from the World Health Organization and Imperial College London told SAGE the lockdown would work but it wouldn’t get rid of the virus.

They said that combining measures such as closing schools, gyms and enforcing social distancing would reduce transmission of Covid-19.

But the virus would inevitably resurge when the restrictions were lifted, they warned. 

The report said: ‘The primary impact of such measures is to delay transmission and reduce peak incidence; when they are lifted, transmission can be expected to resume given the measures only protect the population while in operation (unlike vaccination).’

It added: ‘Measures which are too effective merely push all transmission to the period after they are lifted, giving a delay but no substantial reduction’.

For genuine protection from the virus in future, herd immunity must be developed through vaccination, they said. 

Herd immunity can also develop if most of the population is allowed to catch the virus, but this would result in hundreds of thousands of deaths.  

School closures need to be ‘carefully timed and started early’

An undated paper given to SAGE warned that school closures must start early if they’re going to be done, when the country has around five per cent of its peak number of coronavirus infections.

In the UK, schools were closed from March 20, by which time the virus was rampant across the country. 

This may even have coincided with the peak of the outbreak, given that the highest number of hospital deaths came on April 8 – around three weeks later – and it takes between two and three weeks for fatally ill patients to die after catching Covid-19.

The paper, produced by the same WHO and Imperial experts as the above, said: ‘School closure needs to be carefully timed and started early, when incidence is <5% of its peak value for maximum impact.

‘Eight to 12 weeks of closure are required for maximum reduction of peak incidence.’

The researchers suggested that closing schools could reduce the peak of infections by as much as 40 per cent. 

It has today been 12 weeks since schools were closed across the whole UK, with some now returning for Reception, Year 1 and Year 6 pupils.

Banning large sporting events has ‘imperceptible’ effect on virus

A paper from March 11, before the Government banned large sporting events, said the effect of doing so would be ‘imperceptible’ on the spread of the virus.

Scientists at the London School of Hygiene & Tropical Medicine said that the effect of stopping people going to football matches, for example, would be small on virus spread. 

In fact, they explained, things that people do far more often and with more people in close contact – like going to the pub or to the gym – were likely riskier.

They said: ‘Banning sporting events has a negligible impact on the epidemic. Reducing all leisure contact, which mainly occurs in pubs/bars, restaurants and cinemas would have a much larger (although still modest) impact on the epidemic.

‘Many individuals are likely to choose to avoid such settings anyway, as they perceive them to be risky.’
