In the hopes of looking stupid at the end of the year, then:
Present death toll by standard measure: 128,642.
Expected total by 31/12, if deaths peak at 100 daily: around 140,000
Same date, at a 200 daily peak: c.150,000.
Since the Government is unlikely to impose measures unless the death toll much exceeds this, it's reasonable to expect deaths at these sustained levels, rather than a rapid and then rapidly-shrinking peak, which is part of the motivation for these estimates. The c.160,000 estimate would represent an *average* of 200 Covid deaths a day for the remainder of the year, rather than a *peak*.
Currently, the average is only around 40 a day, but a week ago it was only 25, and a week before that it was 18. At such small numbers it's a little difficult to predict trends reliably, but, still, that represents an approximate two-week doubling of Covid deaths. With no control measures in place, it's reasonable to expect such doubling to continue for at least another few weeks before slowing down, which leads to the scenarios I am describing above.
