With a swathe of lockdown restrictions due to be lifted on ‘super Saturday’ this weekend, new statistics showed that there are still 36 parts of England where coronavirus cases have been increasing.
Release from lockdown was put on hold in Leicester as authorities moved to damp down an upsurge infections which saw the Midlands city record 10 per cent of all positive cases in England in the past week.
Its infection rate of 135 cases per 100,000 over the seven-day period was three times higher than the next worst-affected city in the country.
But figures from Public Health England showed that other areas had also experienced increases in positive cases between the weeks of 13-19 June and 20-26 June.
Doncaster recorded a rise from 11 to 32 in the number of positive cases over the period, while Derbyshire’s figure increased from 23 to 25, Medway from 10 to 17 and Sandwell from 8 to 10.
Some of the sharpest increases were in London boroughs, where the weekly figure rose from 7 to 18 in Hammersmith & Fulham, from 9 to 15 in Hounslow, 5 to 14 in Ealing, 6 to 14 in Westminster, 7 to 13 in Brent and 8 to 12 in Kensington and Chelsea.
Many other council areas which had seen no cases in the first week recorded one or two in the second, while other experienced small numerical increases of one or two cases from a very low base.
The government’s five tests for relaxing lockdown include a requirement for the rate of infection to be decreasing to 'manageable levels’. But the test does not state that infections must be falling across the country.
PHE said it would be wrong to use the figures to predict possible coronavirus hotspots which might need lockdown restrictions reimposed in future.
A spokesperson said that the figures broken down by local authority area were used “as one of a number of indicators to help us and partner organisations to identify trends in local areas and to take action accordingly.
“To use these data in isolation to predict which areas will see significant increases in cases is not appropriate as they do not provide a complete picture of what is happening locally.”
Dr Rupert Suckling, director of public health at Doncaster Council said that the rise in positive tests in the town “coincided with widespread testing in our care homes where we identified a number of asymptomatic positive cases.”
He added: “We have also seen cases in health and care workers, with sporadic cases in schools.
“However, the weekly testing from the week 8-14 June shows a significant reduction.
“We are not complacent and encourage everyone with symptoms to self-isolate and arrange to be tested.
“We are working closely with the local Public Health England centre which has not raised any concerns with us.”
Don Valley MP Nick Fletcher told The Yorkshire Post : "The increase in numbers was due to the increase in testing, we're still testing at these high levels now and there's been a significant reduction in cases but we can't be complacent, the last thing we want to see is a rise."
