The second wave of coronavirus in winter could see a new blockade across the UK, says Matt Hancock, as the report states that 85k could die.
Matt Hancock has warned a second coronavirus wave is a "serious threat" to the UK and would bring more restrictions.
The Health Secretary said the nation could see severe rules being brought back and extensive local blockades if cases increase in the winter.
Matt Hancock admitted that he was concerned about the threats that winter can bring.
He told The Times that a second-wave scenario is "avoidable but not easy," with the reopening of schools bringing a new set of challenges.
"A second wave is clearly visible in other parts of the world," he said.
"It is a very serious threat. But so far in the UK we are managing to maintain the number of new flat cases through a combination of trial and follow-up and local blockages.
"This is the worst reasonable scenario, that we have a serious flu and a growth in coronavirus as people spend more time indoors.
"Cases are coming up again, and we have to use very extensive local blockades or take new national measures. We don't rule that out, but we don't want to see it.”
His comments came when a leaked SAGE report said the coronavirus could kill 85,000 people in the UK in a second wave of the "worst-case scenario" this winter.
The report states that schools are likely to remain open, but other restrictions could be reintroduced to curb the spread of infection.
The Health Secretary admitted that "winter is a concern" for the virus and " we hope for the best but prepare for the worst."
He added that social distancing measures would be in place for the future, suggesting that grandparents could not hug their grandchildren this Christmas without a vaccine.
Last month, Boris Johnson insisted that Britain will not need another national blockade.
It's a very serious threat. But so far in the UK we are managing to maintain the number of new flat cases through a combination of trial and follow-up and local blockages.
The Prime Minister said he "did not believe that we would be in that position again," as he expected a "significant return to normal" in time for Christmas.
He said: "I cannot abandon that tool any more than I would abandon a nuclear deterrent. But it's like a nuclear deterrent, I certainly don't want to use it. And I don't think we're going to be in that position either.
"Not only are we improving in detecting the disease and isolating it locally, but we understand much more which groups it affects, how it works, how it is transmitted, so the possibility of different types of segmentation, of improved shielding for particular groups, is now there."
He said yesterday that schools would close again only as a last resort.
The British are warned to return to work or risk losing their jobs, as Johnson urges workers to return to their desks.
The momentum will include assurances about office security and the benefits of being close to colleagues.
According to reports, ministers will also not shy away from the negative aspects of working from home, as the prime minister is concerned that empty offices delay the country's progress, warning that workers are more vulnerable to being let go if they are not at their desks.
