Respiratory Virus Data

The respiratory virus data tool consists of surveillance dashboards and summary reports.

Respiratory virus data are updated weekly on Thursdays. Reporting will shift to a spring-summer reporting schedule after May 2, 2024; details in Dashboards tab.


Key trends

April 25, 2024 Summary:

Epi week 16: Apr 14 to 20, 2024

With the end of the 2023/24 respiratory virus season, reporting will shift to a spring-summer reporting schedule after May 2, 2024. During the spring and summer, the COVID-19 Situation Report and Genomic Surveillance dashboards will be updated on the first Thursday of each month, and the Wastewater Surveillance dashboard will continue to be updated weekly. Updates to the remaining dashboards will resume in the fall.

Overall respiratory virus activity continues to decrease or remain stable in recent weeks.

  • Influenza B percent positivity and levels in wastewater at select sites have decreased.  

  • Influenza A activity has decreased and remains low. Among subtyped influenza A samples over the past four weeks, H1 and H3 are co-circulating.

  • RSV activity indicators have decreased, and activity remains low.

  • COVID-19 activity has continued to decrease or remained stable across severity indicators, including decreased COVID-19 hospital admissions since early March.

  • The proportions of primary care and emergency department visits for respiratory symptoms have decreased and remained low.

National and international context

Influenza

  • In Canada, most influenza activity indicators have decreased and are within or below expected levels typical of this time of year.

  • In the USA, influenza activity continues to decline nationally and in most areas of the country.

RSV and other viruses

  • In Canada, RSV percent positivity continues to decrease. Other non-SARS-CoV-2 respiratory viruses are within expected levels typical of this time of year.

COVID-19

  • In Canada, COVID-19 activity has continued to slowly decrease or remains at low levels.

  • In the USA, COVID-19 activity has continued to decrease and is low.

Dashboards

Respiratory virus data reporting will shift to a spring-summer reporting schedule after May 2, 2024. The COVID-19 Situation Report and Genomic Surveillance dashboards will be updated on the first Thursday of each month, and the Wastewater Surveillance dashboard will continue to be updated weekly. Updates to the remaining dashboards will resume in the fall.

The respiratory virus dashboards display data for circulating viruses including influenza, COVID-19, respiratory syncytial virus (RSV), enteroviruses/rhinoviruses (ERV), and others.


Reports

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

    • 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.
