OTTAWA -- There is a low daily COVID-19 case count in Ottawa Wednesday, so low it's a negative figure, and Ottawa Public Health has offered an explanation.

OPH reduced the total case count for the city by one case, to 27,334, announcing a new daily update of -1 cases. In a Twitter thread after the dashboard was updated, the health unit said there were actually 20 new cases added Wednesday, but 21 cases were removed from the local total.

"Every case goes through a quality assurance process. It takes a lot of time & effort, especially when you're in the middle of another resurgence and reporting 300+ cases per day. Sometimes, their work will find that a case previously reported in Ottawa wasn't ours," OPH said on Twitter.

"The individual may have been tested in Ottawa, so the lab sample was logged at an Ottawa testing site, but they live in another region (Gatineau, Hawkesbury, etc.). When that happens, the case is removed from our cumulative count & is added to that of another health unit."

OPH said the seven-day averages, such as the weekly per capita rate, are a better determinant of how the level of COVID-19 in the community is changing. On Wednesday, the rate of new cases per 100,000 population in the previous seven days fell to below 25 for the first time in 2021. The weekly average testing positivity rate also fell slightly and the number of active cases continues to fall.

One new death was reported by OPH on Wednesday, bringing the city's pandemic death toll to 583 residents.

Public Health Ontario reported one new case in Ottawa on Wednesday for a cumulative total of 27,315 cases, slightly below OPH's total. Figures from OPH often differ from those provided by Public Health Ontario because the two health agencies pull data for their respective daily reports at different times of the day; however, in the past few days, the discrepancies have been minor.

The province reported zero new cases in the Eastern Ontario Health Unit and the Hastings Prince Edward Public Health region on Wednesday. One new case was reported in the Kingston, Frontenac, Lennox and Addington Public Health region and the Leeds, Grenville and Lanark District Health Unit. The Renfrew County and District Health Unit saw three new cases. 

Across the province, public health officials reported 411 newly confirmed cases and 33 new deaths, but the Ministry of Health noted that 11 of those deaths happened in April and May. There are 932 more cases in Ontario that are considered resolved.

The province says 30,456 tests were processed across Ontario in the last 24 hours.
