The impact of the lockdown can be seen most in the steep decline since Christmas of the number of new cases of Covid-19.
A total of 74,961 new cases were recorded in England in the seven days to February 14 – the equivalent of 133.2 per 100,000 people.
This is down sharply from a peak of 680.8 cases per 100,000 people on January 4.
It is also the lowest seven-day rate since October 4, when the figure stood at 124.8.
The level of rates across England varies considerably, however.
The regional rates for eastern England are the lowest they have been since the autumn.
Hospital activity
The number of patients in hospital in England with Covid-19 has fallen sharply in recent weeks.
