WDGPH reporting 15 new COVID-19 cases over weekend

WELLINGTON COUNTY – Wellington-Dufferin-Guelph Public Health (WDGPH) is reporting 15 new COVID-19 cases between Oct. 29 and 31.

The region’s active case count sits at 31 as of Nov. 1.

That is down from 53 cases one week ago and marks the region’s lowest active case count since mid-August.

The case rate per 100,000 population has, as of Oct. 30, dropped to 11.2 from 17.3 reported a week ago.

The rate of COVID-19 tests returning positive for the virus has fallen from 2% on Oct. 14 to 1.2% as of Oct. 28.

The region’s effective reproduction number, used to measure how many additional cases spread or result from a single case, dropped to 0.81 as of Oct. 30 after remaining above one for much of October. A value of one or above means cases will increase; below one and spread will eventually cease.

There are two people in the region hospitalized with COVID-19, one of which is in an ICU as of Oct. 28. Their vaccination status is not known.

According to provincial data, as of the morning of Nov. 1, there are 156 unvaccinated persons hospitalized with COVID-19 across the province, of which 66 are in an ICU.

Fully vaccinated individuals account for 49 hospitalizations across the province, with 13 in an ICU.

Delta variant

As of Nov. 1, the Delta variant represents 38.4% of the 1,225 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 (99.5%) of all 1,494 positive COVID-19 tests that had their DNA sequenced between Sept. 12 and Oct. 9.

During that time frame, the majority of those Delta variant cases (65.3%) were detected in unvaccinated persons.

Over the same time period, labs sequenced 38 positive cases originating from WDGPH, with all returning positive for Delta.

Delta represents an estimated 66.7% of cases in Wellington County between Oct. 24 and 30. Region-wide, that estimate is 60%.
