BBbevan, what happens afterwards? It depends upon how long you isolate.
When lockdown is lifted, the next 'batch' of people catch it, infections and death rates rise again.
There may be the need for another, or a few more lockdowns. Their purpose is to avoid the NHS becoming too overwhelmed - and buy time.
At some point, perhaps next spring, there may be 'herd immunity', where 80% of the population has immunity and it can't infect easily, so effectively dies out.
There's the possibility of better tests, treatments etc. by then too.
