Respiratory Epidemiological Summaries

Respiratory season surveillance reports summarize key insights for circulating viruses including influenza, COVID-19, respiratory syncytial virus (RSV), enteroviruses/rhinoviruses (ERV), and others.

Special Reports

 

    • The respiratory season report summarizes key insights from 28 August 2022 through to 22 April 2023. Following two years of relatively low non-COVID-19 respiratory illness activity in 2020/21 and 2021/22, the 2022/23 season is characterized by the return to seasonal respiratory virus co-circulation patterns, albeit with some atypical features.

About the Respiratory Diseases data platform

The Respiratory Diseases data platform combines surveillance for COVID-19, influenza and other respiratory pathogens in one platform to monitor trends throughout the respiratory season. The platform is made up of a series of interactive online data pages.

The last respiratory data update of the season was published on May 4, 2023. Updates on influenza and other respiratory pathogens will resume in the fall.

COVID-19 updates will continue monthly throughout the spring and summer.

Changes to COVID-19 data system: May 4, 2023

The British Columbia (BC) COVID-19 surveillance system was updated on May 4, 2023 to use infection episodes of COVID-19 to capture multiple COVID-19 infections in the same person. The update to the system will also capture all hospital and critical care admissions and deaths in a person with a positive lab test. This is a shift from using a system of using first positive lab result for surveillance.
