Friday marks the fourth time in a week and a half that the region has reported double-digit COVID-19 case increases in a single day.

There are at least 81 known active cases in the region. The health unit's figures show at least 93 cases have been reported overall this month.

It's the third time in the last seven days health officials have reported a single-day COVID-19 case jump in the double digits.

The region's total case count is 812, of which 685 people cases have recovered. Fifty-seven people have died, a tally unchanged since June 12.

Monday's reported cases involve two people in their 20s, one person in their 30s, one person in their 40s, and one person in their 70s.

Of Sunday's seven new cases, four people are under the age of 19 and three are in their 20s.

All 11 of Thursday's cases were reported in London, Ont., and involve nine people under the age of 19 and two people in their 20s.

At least four of Wednesday's cases were reported in London, while one was reported in Strathroy-Caradoc. Location data for one was not available.

The cases come on the heels of a community outbreak that has prompted long lines at local testing centres.

London-Middlesex has hit a total of 750 confirmed cases of the novel coronavirus after five new cases were added Sunday.
