Delta had 82 cases for the week of Dec. 12 to 18, 25 more than the week before

COVID-19 cases in Delta continued to climb last week as the number of cases in the region more than doubled.

The latest weekly map released by the BC Centre for Disease Control showing the geographic distribution of COVID-19 cases by local health area (LHA) of residence shows Delta had 82 cases for the week of Dec. 12 to 18, 25 more than the week before and the third week in a row that cases in the city rose by 20 or more.

The overall number of active cases in the Fraser Health region more than doubled last week — 1,411 compared to 700 the week before.

All 13 local health areas (LHAs) in the region saw increases from the previous week, with significant spikes in Tri-Cities (193, up 139), Burnaby (179, up 110), Langley (153, up 88) and Surrey (298, up 76). Eight of the LHAs saw their COVID numbers at least double last week.

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

Broken down by community health service areas (CHSAs), that’s a rate of 11 cases per 100,000 people in North Delta (up from eight the week before, representing 49 new cases), 12 in Ladner (up from four the week before, representing 23 new cases) and 16 in Tsawwassen (up from 10 the week before, representing 28 new cases). 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 performed the week of Dec. 19 was six per cent, up from four the week before. Broken down by CHSA, rates were six per cent in North Delta (up from five), four per cent in Ladner (up from three) and six per cent in Tsawwassen (up from five).

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. 19, 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, unchanged from the week before. Delta also led in second doses among residents 12 and over — 94 per cent, up one per cent 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 94 per cent in North Delta (up one per cent), 94 per cent in Ladner (unchanged) and 93 per cent in Tsawwassen (up one per cent).

First dose rates were virtually identical when limited to adults 18 and over: 96 per cent for Delta as a whole (unchanged from the week before), 96 for North Delta (unchanged), 96 for Ladner (unchanged) and 94 for Tsawwassen (unchanged). Second dose rates were also similar: 94 per cent for Delta as a whole (up from one per cent), 94 for North Delta (unchanged), 94 for Ladner (unchanged) and 93 for Tsawwassen (up from one per cent).

Second dose rates were 92 per cent for Delta as a whole (unchanged), 91 for North Delta (up one per cent), 97 for Ladner (up one per cent) and 91 for Tsawwassen (unchanged).

The dashboard now also shows first dose coverage among kids ages 5-11. Delta as a whole stood at 32 per cent (up nine per cent), North Delta at 24 (up five), Ladner at 42 (up 14) and Tsawwassen at 44 (up 15).

First dose rates for those 18-49 and those 50 and over were nearly the same and in line with other age categories.

For adults 50 and over, first dose coverage in Delta was 95 per cent (unchanged from the week previous).

As of Thursday morning (Dec. 23), 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 four Delta schools: Cougar Canyon Elementary (Dec. 9, 10, 13, 14, 15, 16 and 17), English Bluff Elementary (Dec. 9), Seaquam Secondary (Dec. 9) and South Delta Secondary (Dec. 13, 14 and 15).

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.”
