COVID-19 wastewater signal trending down as school returns

The latest data showing the amount of COVID-19 in Ottawa’s wastewater is showing a downward trend through the end of August, just as students return to their classrooms.

Preliminary projections from the Ottawa COVID-19 wastewater monitoring project show the downward trend is expected to continue for the first week of September.

While the viral average has been trending downward for the latter part of August, the viral signal is higher than it was at this time last year and in 2020.

Hundreds of thousands of students returned to elementary, high school, and post-secondary classrooms Tuesday and health experts are anticipating a rise in transmission in the coming weeks.

Ottawa Public Health reported one new COVID-19 death over the long weekend. The number of residents in hospital because of an active case of COVID-19 dropped to 20 from 30 last Tuesday. One person is in the ICU.

OPH hospitalization figures only represent Ottawa residents who are in hospital because of an active case of COVID-19. Local hospitals report higher figures, which include patients who were admitted for reasons other than COVID-19 but have tested positive and patients who are not from Ottawa.

Here is a look at how many COVID-19 patients are in each hospital:

  • The Ottawa Hospital: 61 patients (up from 58 on Aug. 29)
  • Queensway Carleton Hospital: 11 patients (up from 7 patients Aug. 30)
  • Montfort Hospital: 15 patients (up from 12 patients Aug. 30)
  • CHEO: Five patients (unchanged from Aug. 30)

Since the first case of COVID-19 was reported in Ottawa in March 2020, OPH has reported 81,035 laboratory-confirmed cases of COVID-19, including 878 fatal cases. The number of known active cases and active COVID-19 outbreaks is on the decline.

The Canadian Broadcasting Corp. and Radio-Canada will eliminate about 600 jobs and not fill an additional 200 vacancies. The cuts at CBC come days after the Liberal government suggested it may cap the amount of money CBC and Radio-Canada could get under a $100 million deal Ottawa recently signed with Google.
