Yes the number of deaths is still climbing, but it is encouraging that the number of new cases is beginning to show signs of levelling out. The drop of 715 new cases today is quite a large fall and could be an anomaly so I wonder if we might see a higher number tomorrow.
Over the last 4 days (including the latest results released half an hour ago), new cases have been as follows:
1 Apr 4,324
2 Apr 4,244
3 Apr 4,450
4 Apr 3,735

Although it is still too early to say for sure - and of course, how the British public react to the nice weather this weekend and the imminent long Easter weekend soon after will play a huge role - it seems at the moment that the spread might be slowing (I cannot emphasise might enough).
This would make sense given that incubation times are normally within a 2 week range and we are almost 2 weeks into lockdown.
It is not surprising that deaths are still rising at this stage. If, for example, the average time from diagnosis to death was 2 weeks, we could potentially see the number of cases fall for a fortnight before we see any improvement in the daily number of deaths.
