Leicester is set to remain under the current lockdown measures for an extra two weeks as restrictions are relaxed across the rest of England on Saturday.
The move would be part of what Prime Minister Boris Johnson referred to as a "whack-a-mole" strategy, where shutdown rules will be kept in place or reimposed in areas where the infection rate is deemed to be too high.
As the people of Leicester prepare for an extended wait out of the current restrictions, Sky News has asked the experts how you might go about locking down a city.
Who makes the decision?
Government officials have said the existing lockdown measures should remain in force in Leicester for an extra fortnight, but infectious diseases expert Dr Bharat Pankhania has said such decisions should be devolved to local experts on the ground.
He told Sky News: "If the outbreaks are managed locally with all the local data to hand as well as a local outbreak committee with input from both local and national centres, the local experts will have a much earlier and thus timely sense of which way the outbreak is going and thus act in a much faster and timely manner.
"Our current system of centralised control results in a delay, a lack of precision and timeliness to act fast."

Dr Pankhania, who has devised both national and international communicable disease control action plans, said it is important to allow decisions to be made locally even if it they are contrary to the direction of travel the government wishes to pursue.
He added councils would make their decisions on the advice of their directors of public health and a team of local experts which would include local Public Health England consultants in communicable disease control, local authority public health experts and national level experts.
Dr Pankhania added that he has found this has worked very well in the past when he has dealt with many outbreaks.
Dr Mike Tildesley, an expert in infectious diseases at the University of Warwick, told Sky News: "I would say it is important that the relevant regions are involved in the process of deciding whether there should be a local lockdown.
"I know from the projects that I work on around the world that it is extremely important to have someone local on the ground working to advise us. Because they're the ones that actually know where the virus is circulating and what the risks might be."
How should lockdowns be enforced at a local level?
Dr Pankhania acknowledges that this will be not be easy and said the first thing needed would be to reduce people's movements and gatherings in the city.
He said: "Places where people come out and gather need to be shut down. In other words, creating a mini lockdown.
"With respect to movements in and out of a city like Leicester, that would have to be reduced as well.
"If you take where I live in the South West, we've explored this and we've said, 'we'd like to be able to say no visitors coming to the South West because we've got an outbreak'.
"And then you would have to tell businesses like pubs, hotels and those in the entertainment industry to close.
"That immediately dampens down human activity, and that is all you can do really."
Dr Pankhania said local authorities should have the power to say pubs within the 10-mile boundary of the epicentre of the area's outbreak are shutting and will remain closed until advised otherwise.
He said that no model is perfect and each local authority will have to do their best, adding: "You hope and pray that you've got enough powers and enough persuasion that people will follow and listen."
Dr Pankhania continued: "These precautionary messages would best have been given out with stern warnings earlier and repeated well before the lifting of the lockdown. It is much more difficult to get purchase with these precautionary messages once the go ahead for lifting the lockdown has happened."
He added for that reason strict lockdown measures at a local level need to be enforced with strong messages given by a recognised and respected local director of public health.
How can local lockdowns be made as effective as possible?
Dr Pankhania said shutdowns at a local or regional level will be most effective when extensive local testing and tracing practices are in place.
He continued: "So far we haven't even had the capacity to test extensively, we are testing in a partial manner only. On the same measures, our centralised contact tracing service is not as precise, flexible, and run by local experts who know of the nuances and how to get the best out of a case. The current contact tracing system relies on following algorithms and it lacks that finesse.
"So our lockdown is only a lockdown, but it isn't lockdown plus plus, which is testing and tracing whilst locked down.
"I would be saying – 'I am the director of public health for Leicestershire, I'm informing people we have an increasing outbreak, you need to not gather, you need to stay away from other humans, you need to stop most activity involving contacts with other humans, only essential things need to continue, we need to act fast and immediately to reduce the rising numbers of cases, I need your co-operating to achieve this.
