Geographies can be displayed by municipality or local geographic area (LGA). When viewing by municipality, regions are defined by rural municipalities, city boundaries, and urban service areas; smaller regions (i.e. towns, villages, and reserves) are incorporated into the corresponding rural area. Cases without a postal code or incorrect postal codes are not included. Location information missing/invalid for: 43 case(s).

Data export

Data are subject to change. Fluctuations are expected as cases are investigated and updated. Current day is partial. Data are provided for export in excel and csv formats.

Data notes

Data sources

The Provincial Surveillance Information system (PSI) is a laboratory surveillance system which receives positive results for all Notifiable Diseases and diseases under laboratory surveillance from Alberta Precision Labs (APL). The system also receives negative results for a subset of organisms such as COVID-19. The system contains basic information on characteristics and demographics such as age, zone and gender.

Recovered is based on the assumption that a case is recovered 14 days after a particular date. For confirmed cases, we used specimen collected date and for probable cases, this is the date reported to Alberta Health.

Information such as hospitalizations and ICU admissions are received through enhanced case report forms sent by Alberta Health Services (AHS).

Disclaimer

The content and format of this report are subject to change. Cases are under investigation and numbers may fluctuate as cases are resolved. Data included in the interactive data application are up-to-date as of midday of the date of posting.
