COVID-19 cases are on the rise again in Delta.

This after the number of cases in the city more than doubled during the week ending Dec. 4.

The overall number of active cases in the Fraser Health region decreased slightly last week — 700 compared to the week before.

Seven of the 13 local health areas (LHAs) in the region saw increases from the previous week, most notably Surrey (222, up 75 from the week before) and Burnaby (69, up 20).

Data shared on the BC CDC’s COVID-19 Surveillance Dashboard shows Delta had an overall daily average of seven new cases per 100,000 people for the week of Dec. 13, up from six the week before.

Broken down by community health service areas (CHSAs), that’s a rate of eight cases per 100,000 people in North Delta (unchanged from the week before), four in Ladner (unchanged) and 10 in Tsawwassen (up from two). The CHSA of Tsawwassen is comprised of both the Delta community and the Tsawwassen First Nation.

Delta’s total case count over that time frame represented two per cent of cases in B.C. that week, unchanged from the week before. Delta is home to two per cent of the province’s population.

The positivity rate in Delta based on public tests the week of Dec. 13 was four per cent, unchanged from the week before. Broken down by CHSA, rates were five per cent in North Delta (down from six), three per cent in Ladner (unchanged) and five per cent in Tsawwassen (up from two).

The dashboard also shows breakdowns of vaccine coverage across the CHSAs by age (5-11, 12+, 12-17, 18+, 18-49 and 50+) and by whether people have received their first or second dose, or in the case of those 70+, their third dose.

As of Dec. 13, Delta continued to lead other LHAs in Fraser Health with 96 per cent of adults aged 12 and over having received at least their first does of vaccine, up one per cent from the week before. Delta also led in second doses among residents 12 and over — 93 per cent, unchanged from the week before.

Broken down by CHSA, that’s 96 per cent first dose coverage in North Delta (unchanged from the week before), 96 per cent in Ladner (unchanged), and 94 per cent in Tsawwassen (unchanged). In terms of second dose rates, that’s 93 per cent in North Delta (unchanged), 94 per cent in Ladner (unchanged) and 92 per cent in Tsawwassen (unchanged).

Second dose rates were 92 per cent for Delta as a whole (up one per cent), 90 for North Delta (unchanged), 96 for Ladner (unchanged) and 91 for Tsawwassen (up one per cent).

The dashboard now also shows first dose coverage among kids ages 5-11. Delta as a whole stood at 23 per cent (up 15 per cent), North Delta at 19 (up 12), Ladner at 28 (up 18) and Tsawwassen at 29 (up 19).

As of Thursday morning (Dec. 16), there were no outbreaks at any Delta long-term care, assisted living or independent living facilities, there were no public exposure notifications in the city, and no Delta businesses had been temporarily closed due to COVID-19 spread among workers.

Also as of Thursday, Fraser Health’s website listed exposures at six Delta schools: Burnsview Secondary (Dec. 7), Chalmers Elementary (Dec. 7), Cougar Canyon Elementary (Dec. 1, 2, 3, 6, 7, 8, 9, 10, 13 and 14), English Bluff Elementary (Dec. 6, 7 and 8), Gibson Elementary (Dec. 1, 2 and 3) and Seaquam Secondary (Dec. 1, 2, 3, 7, 8 and 9).

Fraser Health defines exposure as “a single person with lab-confirmed COVID-19 infection who attended school during their infectious period.” Two or more individuals is defined as a cluster, while an outbreak describes a situation involving “multiple individuals with lab-confirmed COVID-19 infections when transmission is likely widespread within the school setting.”
