Public health reports significant jump in COVID-19 cases over weekend

The region’s active case count now sits at 104, the highest it has been since reaching 106 on June 11. There were 57 active cases in the region one week ago and just 21 on Aug. 3.

The region’s case rate per 100,000 population is on the rise – from 6.4 at the beginning of August to 31.1 as of Aug. 28.

On Aug. 1 less than one per cent of COVID-19 tests were returning positive for the virus, but that rate has is now trending upward, increasing to 3.2% as of Aug. 26.

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 1.28 as of Aug. 28. A value of one or above means cases will increase; below one and spread will eventually cease.

There are four people in the region hospitalized due to COVID-19, with three in an ICU as of Aug. 26. Their vaccination status is not known.

According to provincial data, as of the morning of Aug. 30, there are 238 unvaccinated persons hospitalized with COVID-19 across the province, of which 89 are in an ICU.

Fully vaccinated individuals account for 38 hospitalizations across the province, with eight in an ICU.

Delta variant

As of Aug. 29, the Delta variant represents 53.49% of the 473 COVID-19 cases confirmed in the health region since the variant was first reported here on June 15.

On June 14, 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 (89.5%) of all 2,750 positive COVID-19 tests that had their DNA sequenced between July 11 and Aug. 7.

The proportion of cases returning positive for Delta increased by 2.3% from a week earlier, to 93.5% between Aug. 1 and 7.

From July 11 to Aug. 7, labs sequenced 64 positive cases originating from WDGPH, with 63 returning positive for Delta.
