Total Cases
Figure 4: COVID-19 cases in Alberta by day and case status. Recovered is based on the assumption that a person is recovered 14 days after a particular date (see data notes tab), if they did not experience severe outcomes (hospitalized or deceased). Cases are under investigation and numbers may fluctuate as cases are resolved. Data included up to end of day January 04, 2021.

Geographies can be displayed by municipality or local geographic area (LGA). When viewing by municipality, regions are defined by metropolitan areas, cities, urban service areas, rural areas, and towns with approximately 10,000 or more people; smaller regions (i.e. 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: 369 case(s).

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. The Communicable Disease Reporting System (CDRS) at Alberta Health and the Communicable Disease Outbreak Management (CDOM) system at Alberta Health Services contains information on COVID-19 cases. Data Integration and Measurement Reporting (DIMR) database at Alberta Health Services contains up to date information on people admitted and discharged from hospital in Alberta.
Active and recovered status is a surveillance definition to try to understand the number of active cases in the population. It is not related to clinical management of cases. It is based on the assumption that a case is recovered 14 days after a particular date. For confirmed cases, specimen collected date is used and for probable cases date reported to Alberta Health is used. If a case is hospitalized, the recovered date is when their symptoms have resolved based on case follow-up, or 10 days after being discharged.
Information such as hospitalizations and ICU admissions are received through enhanced case report forms sent by Alberta Health Services (AHS).
Comorbidities
The following comorbitities are included in respective analyses: Diabetes, Hypertension, COPD, Cancer, Dementia, Stroke, Liver cirrhosis, Cardiovascular diseases (including IHD and Congestive heart failure), Chronic kidney disease, and Immuno-deficiency.
