EDMONTON -- Data on COVID-19 is largely focused on the international, national or provincial level, but statistics compiled by CTV News illustrate how the coronavirus is affecting Edmonton and its individual communities.

Alberta Health Services divides Edmonton up into 15 health subzones named for their home communities. 

Since early April, the province has provided daily updates on the number of COVID-19 active cases, recoveries and deaths in each of those subzones as well as totals for the city itself.

This page is divided up into four sections: overall city data, subzone (community) level data, testing data and methodology.

Scroll down or follow the links below to navigate to each section.

CITY OF EDMONTON

The city of Edmonton is distinct from the Edmonton zone, which includes communities far beyond the city itself. You can see a map displaying the boundaries of the five AHS health zones across the province here

Unless otherwise specifically indicated, numbers on this page are for the city itself and not the zone.

See the methodology section below for how a recovery from COVID-19 is defined by AHS.

COMMUNITIES

The 15 Edmonton AHS subzones cover the vast majority, though not all, of the area inside the city's coroporate boundaries.

You can see a rough map of the subzones below. For a zoomable version, visit the province's interactive data site and click on the geospatial tab.

TESTING DATA

Testing data for specific cities isn't yet available so these graphs display data from the Edmonton Zone as opposed to the city itself. 

The Edmonton Zone had a population of just over 1.4 million people in 2018, according to AHS. The same year, the province estimated the city of Edmonton's population at just over 1 million people.

METHODOLOGY

Boundaries

The graphs above were assembled using two versions of the province's interactive data map, each with different borders. 

The city-specific graphs draws data from the city of Edmonton as defined by its geographic corporate boundaries.

The community-level graphs draw data taken from the province's 15 Edmonton-area health subzones.

Their boundaries closely resemble the city's borders but with some exceptions. As a result, some areas within Edmonton's corporate boundaries, largely near the city's southern boundary, are included in suburban health zones.

Cases are attributed to the subzone of a patient’s primary residence. You can see population estimates for each subzone here.

Case Counts

The updated daily case count reflects the number of new, active cases (people who are now newly ill with COVID-19). 

The daily change in active cases are determined by subtracting the number of newly recovered cases from the number of new cases. A positive value represents an increase in net active cases, with a negative value indicating the opposite.

The province often revises data, and reclassifies cases to other health zones or subzones which can cause a sudden rise or drop in cases for a given location.​

Reclassifications can occur for a number of reasons, including: 

  • A patient's contact information was updated to reflect his or her proper address. 
  • Further testing revealed a patient did not, in fact, contract COVID-19. 
  • Data entry errors.

The province published new numbers daily March, April, May and June, with subzone data being available since early April. Starting the weekend of July 4, the province will release updated data on weekdays only, with no scheduled updates on holidays and weekends.

Recoveries

Recoveries are defined by Alberta Health Services as follows:

  •  A return to health after 14 days of isolation for those with COVID-19 but who experienced only mild symptoms.
  •  If hospitalized due to COVID-19, anyone who does not require additional hospitalization or treatment in the 10 days after they left the hospital.
  •  If tested, such as a health care worker, two negative tests at least 24 hours apart.
