On Monday 23 March, prime minister Boris Johnson placed the UK on lockdown, meaning that all but essential businesses were to close with immediate effect, while members of the public were to stay in their homes except to shop for essentials or go out in certain circumstances, including one form of daily exercise.

Three weeks later, Dominic Raab announced lockdown would continue for at least another three weeks into May and said lifting restrictions too soon would only spread the virus, further damaging the economy.

On Sunday 10 May, Mr Johnson made a televised address to the nation in which he outlined a road map for how England’s lockdown restrictions would be relaxed in the coming weeks using a new Covid Alert System.

During the daily press conference on Thursday 28 May, the prime minister provided a further update on easing lockdown measures in England, stating that the changes would be "limited and cautious".

The new rules stipulate that from Monday 1 June, groups of up to six people from different households are allowed to meet outside, in areas including parks and private gardens. "These changes mean friends and family will start to meet loved ones," Mr Johnson said.

However, people will still need to remain at least two metres away from those who are not from their own household.

Despite the easing of lockdown restrictions, England’s chief medical officer, Chris Witty, has previously stated that social distancing measures could be in place until the end of the year unless a vaccine is found sooner — which he added was unlikely.

He said a sudden lifting of all restrictions would be a “wholly unreasonable” expectation for the public to have.

He said: “In the long run, the exit from this is going to be one of two things, ideally. A vaccine, and there are a variety of ways they can be deployed... or, and or, highly effective drugs so that people stop dying of this disease even if they catch it, or which can prevent this disease in vulnerable people.

“Until we have those, and the probability of having those any time in the next calendar year is incredibly small, and I think we should be realistic about that.

“We’re going to have to rely on other social measures, which of course are very socially disruptive as everyone is finding at the moment. But until that point, that is what we will have to do.”​

So when may the lockdown in the UK come to an end?

Unfortunately, this is not an answer that can be easily answered due to the lack of evidence currently available.

Katrina Herren, chief clinical officer at Doctorlink, the leading symptom assessment provider to the NHS, states that understanding when lockdown may come to an end will require more time.

“This is because we are only weeks into the lockdown and only from now onwards are we seeing cases where the virus has been transmitted since lockdown,” she says.

Herren explains to The Independent that every day that passes provides “more information from our own country and from other countries that are ahead of us in the lockdown”.

Professor Robert Dingwall, a part-time professor in the School of Social Sciences at Nottingham Trent University and a pandemic disease expert, says that in his opinion, it is “premature for any responsible scientist to start speculating about when it might end”.

He tells The Independent that there is a "real danger" of providing people with "false hope", which is why more time is needed in order to obtain data that will provide "some sense of how the outbreak is playing out in this country".

Professor Keith Neal, Emeritus Professor of the Epidemiology of Infectious Diseases at the University of Nottingham, explains that there are two “extreme ways of managing an epidemic”.

The first, he tells The Independent, would be to allow the virus to spread through the population quickly as a means of achieving herd immunity, which would inevitably result in health services becoming overwhelmed and an increasing number of fatalities. The second would be to keep the public in isolation until a vaccine is created, an eventuality that he doesn’t believe will come to fruition for another 18 months. As neither of these options are feasible, a different approach has to be taken, the professor states.

The release of lockdown in stages

On 10 May, Mr Johnson announced a minor loosening of lockdown restrictions, with new guidelines that allow people to take part in unlimited outdoor exercise and sunbathe in local parks commencing on Wednesday 13 May.

A further update on 28 May by the prime minister outlined a greater easing of lockdown rules, with members of the public being allowed to see people from other households in larger groups, albeit at a safe distance.

Monday 1 June will see the phased reopening of shops and primary schools start to take place. The government also hopes to re-open at least some of the hospitality industry and other public places, at the earliest by July.

However, Mr Johnson stressed that the easing of restrictions in England will only occur if the transmission rate for coronavirus remains low. “It depends on all of us – the entire country – to follow the advice, to observe social distancing, and to keep that R down,” he said on 10 May in reference to the R rate, which is a key measure of how much Covid-19 is spreading.

The prime minister added that now is not the time to “simply end the lockdown”. “Instead we are taking the first careful steps to modify our measures,” he said.

The coronavirus pandemic has been compared on several occasions to a wartime era. This, Professor Dingwall says, has led to people believing there will be “some sort of equivalent of VE Day, and we will officially declare it over and be able to go out and have a big party”.

However, it is “far more likely that what we’ll actually see is a progressive relaxation of measures over quite a long period”, he explains.

A recent study published in the Lancet Child & Adolescent Health journal found that the closing of schools do not appear to have a significant effect on the spread of infections during outbreaks such as Covid-19.

Following the analysis of 16 studies, researchers estimated that school closures would reduce deaths by around 2 to 4 per cent during the coronavirus pandemic in the UK, less than other social distancing measures.

The researchers warned that the “economic costs and potential harms” of mass school closures are very high, particularly for the most disadvantaged children, suggesting that playgrounds could be closed and social distancing introduced in classrooms if schools do reopen.

“It does look like the evidence for continuing with school closures might not be very robust,” Professor Dingwall says, stating that the reopening of schools “would be a huge step forward in getting the country running normally again”.

Professor Neal theorises that other changes to ease the lockdown may include enforcing spaced seating arrangements at restaurants and removing queues from bars, should food and drink establishments be allowed to resume everyday operations, aside from takeaway and delivery.

However, the plan to ease the lockdown in the UK “will need to be very carefully planned to consider the potential risk of an increase in the cases, the economic impact and the wider health of people in society among other factors”, Herren stresses.

Could the distribution of antibody tests increase the likelihood of the lockdown being removed?

In a report published by the Department of Health and Social Care on 4 April, it stated that the government was working with several companies who are offering antibody tests and “are evaluating their effectiveness”.

“These antibody tests are brand new. In fact, they are still being developed and there is not yet one that has been proven to work as we would require,” the report states. “No government in the world has yet rolled out a full Covid-19 antibody testing programme.”

Antibody tests would allow health practitioners to find out whether a person has already recovered from the coronavirus and thus built some degree of immunity to it.

“Once the antibody test is sorted, and we know exactly how to make the test, then it’s quite easy to make hundreds of thousands of them very quickly,” Professor Neal says. “We’re in a real dearth of information.”

On Friday 3 April, health secretary Matt Hancock said that the British government had not yet found an antibody test that is “good enough to use”, also admitting that the tests are unlikely to become widely available until the end of April.

However, on Thursday 14 May it was reported that a “100 per cent accurate” antibody test had been approved for use in the UK for the first time.

It was recently reported that a new antibody test that is said to be 99 per cent accurate has been certified for use in Europe.

Furthermore, a blood-screening company that claims its researchers in Edinburgh have developed a “fast and accurate” antibody test has urged ministers in the UK and Scottish governments to begin talks so that the NHS can benefit from them.

Gaining a better understanding of how many people have become immune to the virus could lead to lockdown measures being eased in future, Professor Dingwall says.

“It will help when we have some idea of what the actual level of immunity in the population is,” he says. “If we are approaching a level of immunity where the virus is beginning to run out of people to infect — we might be able to track that on something like a regional basis — then that might give us some more latitude for saying we can relax in these areas.”

On the other hand, if healthcare practitioners were able to state whether or not a person is immune to the virus, would that mean that only those who are immune would be allowed to leave their homes, Professor Dingwall asks.

Professor Neal adds that “at the moment, there is no perfect strategy”. “This may be a world pandemic, but it’s actually a series of epidemics in different countries,” he says.

“Nobody’s got any real idea what best strategy to use, it’s sort of making it up as you go along. I think it’s actually quite difficult to decide when to release the lockdown.”

On Thursday 28 May, the NHS Test and Trace scheme was launched, which will allow people with coronavirus to trace those they have made contact with and thus reduce further transmission of the virus. Anyone who has symptoms of the virus is encouraged to request a test through the NHS as soon as possible.

However, the accompanying app has been delayed by several weeks as it is currently being trialled in the Isle of Wight.
