A steep fall in coronavirus cases saw just 12 positive tests last week in Norfolk, which had amongst the lowest coronavirus infection rates in England.

Public Health England on Thursday published updated numbers using two types of data, Pillar 1 – tests carried out in hospitals – and Pillar 2 – tests covering the wider population, including results from sites like Postwick Park and Ride.

This data shows the average number of cases per 100,000 people in each county and council area.

In Norfolk, the latest figures reveal that in the week up to June 28, there were 1.5 positive test results per 100,000 people – down from 4.3 the week before.

The PHE data shows Norfolk ranked 120 out of 151 local authorities for the rate of new coronavirus cases up to June 28, whilst Suffolk is ranked even lower at 133.

The inclusion of Pillar 2 data in the figures comes after public health officials had previously said they were not getting the full picture.

PHE had only published local figures on the number of health and care staff testing positive.

Louise Smith, director of public health in Norfolk, said: “We welcome the national publication of the total rates and locations of infections in the county, because it is important for everyone to understand what the current situation is.

“Over the past few weeks in Norfolk, we have been monitoring these data closely and the number of daily cases has fallen.

“There were 12 positive cases across the whole county between June 24 and 30 showing that the rate of infection in Norfolk is currently low.

“The additional combined Pillar 1 and 2 data published today has not changed our overall position and reports that 2,842 positive cases of Covid-19 have been diagnosed in Norfolk to date.”

The other top 10 highest positive test rates were seen in northern towns and cities including Bradford (45.8); Barnsley (35.1); Rochdale (35), Oldham (30.1); Kirklees (26.2); Rotherham (26.1) and Sheffield (24.4).

Ms Smith said despite the lower rate locally it was important not be complacent and to stick to guidance.

She said: “To keep infection low we need to keep washing our hands and keeping our distance from others – that is particularly important as further restrictions are lifted at the weekend. If you have symptoms, stay at home and book a test through NHS Test and Trace – that is the best way to help us monitor the disease and reduce the spread. We need to work together to protect ourselves, protect others and protect Norfolk.”
