And in the seven days to July 28,there were 584 cases recorded – meaning case numbers have risen by 40%.
The most affected age group is those aged between 20 and 29, with 30% of all positive cases diagnosed in people within this range.
The next most affected is those in their 30s, with one-fifth of cases found in this age group. Young people aged 10 to 19 make up 17%.
For the first time since the seven days ending February 17, positive tests have been returned in every age group – from those under nine to those over 90.
In Peterborough, 10.4% of the 7,894 people tested were found to be positive.
Hospitalisations are also increasing, with 46 Covid-related admissions to North West Anglia NHS Foundation Trust (NWAFT) hospitals in the week to August 8 - an increase of 20 admissions from the previous week.
As of August 10 there were 37 coronavirus patients in NWAFT hospitals. Six of these required mechanical ventilation (MV) beds.
This is up from 25 patients on August 3 (with three requiring MV beds) and well up from a month ago (July 10), when there were three Covid patients, none of whom required an MV bed.
The rolling case rate in Peterborough is the seventh highest in England, sitting at 469.7 per 100,000 people.
All this comes as NHS data puts Peterborough well below the national average when it comes to vaccinated residents.
Around 69% of people within the city have had their first dose of a Covid jab – but across the UK as a whole that figure is 89%.
In Peterborough, 56% of people are double-jabbed, but nationwide it is estimated that 75% of people have had both doses.
Residents are being encouraged to #DoTheRightThing and either book an appointment or attend one of the many walk-in clinics to get the Covid vaccine.
Dr Gary Howsam, chair of Cambridgeshire and Peterborough’s clinical commissioning group, said: “We want the exit route from the pandemic to be as smooth as is possible.
“We do not know what is round the corner, we need to be conscious that we may take two steps forward and one step backward.
“The simple hands, face, space, ventilate messages are equally important today.
“We know case numbers are high, but those hospitalised or dying is reduced and that is largely because of the vaccine.
“We know vaccines are safe and effective and we have a plentiful supply.”
