WDGPH reporting 72 new COVID-19 cases over weekend

WELLINGTON COUNTY – Wellington-Dufferin-Guelph Public Health (WDGPH) is reporting 72 new COVID-19 cases over the weekend (Sept. 10 to 12).

The region’s active case count now sits at 125, a level last seen in early June.

The region’s case rate per 100,000 population has declined from 35.6 on Sept. 5 to 34 as of Sept. 11.

The rate of COVID-19 tests returning positive for the virus has declined slightly from 3.8% on Sept. 3 to 3.4% as of Sept. 9.

The region’s effective reproduction number, used to measure how many additional cases spread or result from a single case, has remained above one since Aug. 22 and sits at 1.03 as of Sept. 11. A value of one or above means cases will increase; below one and spread will eventually cease.

There are five people in the region hospitalized due to COVID-19, none of which are in an ICU. Their vaccination status is not known.

According to provincial data, as of the morning of Sept. 13, there are 262 unvaccinated persons hospitalized with COVID-19 across the province, of which 103 are in an ICU.

Fully vaccinated individuals account for 57 hospitalizations across the province, with 15 in an ICU.

Delta variant

As of Sept. 12, the Delta variant represents 50% of the 667 COVID-19 cases confirmed in the health region since the variant was first reported publicly here on June 15.

On June 14, Public Health Ontario (PHO) began allowing all positive COVID-19 samples to be sent for whole genome sequencing, the only way to truly determine how many cases of Delta there are within local health units.

According to PHO data, Delta represented the vast majority (96.3%) of all 5,950 positive COVID-19 tests that had their DNA sequenced between July 25 and Aug. 21.

The proportion of cases returning positive for Delta increased by 2.1 percentage points from a week earlier, to 98.9% between Aug. 15 and 21.

From July 25 to Aug. 21, labs sequenced 79 positive cases originating from WDGPH, with 77 returning positive for Delta.

Delta represents an estimated 72.7% of cases in Wellington County between Sept. 5 and 11. Region-wide, that estimate is 65.1%.
