I think I read that the average time lag between covid infection and death is about three weeks. According to PHE 88% of Covid deaths occur within 28 days of the first positive specimen date.

The average number of cases over the last week was 3,050, which is 41% up on the previous week (1,812). That had been 31% up on the week before that (1,244).

We should therefore start seeing what effect this increase in positive tests has over the next couple of weeks.
