A total of 28,289 people have had COVID-19 in Cumbria, the latest figures show.
It comes after Public Health England changed the way it reported the figures from Friday.
Revision to historical case data in England also led to the removal of 5,500 cases nationally over three days last week.
The number of positive cases reported in Cumbria by 9am today was 37 higher than last Monday.
Cases that are identified through a positive lateral flow test – those which can deliver results within half an hour – are no longer being counted if the person then takes a PCR test, which is sent to a lab to be checked, and receives a negative result within three days.
These cases are now being removed daily.
Overall, the rate of infection in Cumbria now stands at 5,658 cases per 100,000 people, lower than the England average of 6,925.
Across the UK, the number of recorded cases was 12,144 higher than last Monday, with the total now standing at 4,464,900.
Cumbria’s cases were among the 616,266 recorded across the North West, a figure which rose by 3,589 over the period.
Cumulative case counts include patients who are currently unwell, have recovered and those that have died.
