In the short term, things will seem to get much worse, in that the number of officially confirmed cases will reach 10 thousand in a few days (and possibly 100 thousand early next month), and the corresponding number of deaths will increase considerably. Our health services may not be able to cope.
However, the apparent trends must change, else the total number of related deaths would exceed the total number of reported cases, which would be absurd. I think that the anticipated "peak" will occur much sooner than currently expected by the government's advisers. For Greater London, I think it will occur in April, and the rest of the UK will follow suit in May.
