I don't think a solution to ending the lockdown exists.
I think there are solutions to ending the lockdown, all you have to do is look at what several other countries have done and have had far less infections and deaths than we have. South Korea would be one example, they haven't even needed to have a proper lock down there.
My worry is that I have my doubts this government is capable of putting systems and procedures in place so that a gradual easing of restrictions could begin in a few weeks time.
We will need a massive increase in testing capability together with swift and efficient contact tracing. This will need hundreds of thousands of people involved, perhaps use some of the 750,000 volunteers that came forward. Phone apps should be used like they have in other countries to help in the tracing of people who have been in close contact with anyone who has been infected.
Anyone tested should have the results of the test in as short a time as possible, I think some countries can do this in just a few hours if that's the case then we should be able to do it too.
Wearing of mouth coverings in busy public places should be strongly advised perhaps even made compulsory. Hand sanitizer and free masks should be available in these busy public places (shopping arcades, train and tube stations etc.)
People employed to regularly wipe down with the appropriate chemicals things like hand rails, cash dispensing machines, lift buttons etc. People employed at entrances to shops, stations and other busy areas to take peoples temperatures using the infra red type detectors but the medical ones not the industrial ones that are inaccurate.
I haven't needed to come up with any of these things myself, these are all things I have seen taking place in other countries which have coped far better than we have.
If we could get all this in place then a gradual easing of restrictions could happen. but pubs, cinemas and cafes would be well down the list of things that should be opened first.
