WDGPH reporting 32 new COVID-19 cases over weekend

WELLINGTON COUNTY – Wellington-Dufferin-Guelph Public Health (WDGPH) is reporting 32 new COVID-19 cases over the weekend (Oct. 15 to 17).

The region’s active case count now sits at 81 and its case rate per 100,000 population has increased from 17.3 on Oct. 10 to 21.8 as of Oct. 16.

The rate of COVID-19 tests returning positive for the virus has risen from 1.4% on Oct. 8 to 2% as of Oct. 14.

The region’s effective reproduction number, used to measure how many additional cases spread or result from a single case, is holding at 1.04 as of Oct. 16 after sitting at the same on Oct. 10.  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 with COVID-19, two of which are in an ICU as of Oct. 13. Their vaccination status is not known.

According to provincial data, as of the morning of Oct. 18, there are 176 unvaccinated persons hospitalized with COVID-19 across the province, of which 76 are in an ICU.

Fully vaccinated individuals account for 49 hospitalizations across the province, with 18 in an ICU.

Delta variant

As of Oct. 17, the Delta variant represents 39.1% of the 1,131 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 (99.2%) of all 3,696 positive COVID-19 tests that had their DNA sequenced between Aug. 29 and Sept. 25.

Over the same time period, labs sequenced 72 positive cases originating from WDGPH, with all returning positive for Delta.

Delta represents an estimated 66.7% of cases in Wellington County between Oct. 10 and Oct. 16. Region-wide, that estimate is 55.9%.
