Respiratory Virus Data

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

Respiratory virus data was last updated on September 5. Weekly updates will resume on September 26.


Key trends

Epidemiological week 35: Aug 25 to 31, 2024

September 5, 2024

Overall, COVID-19 severity indicators remain stable with moderate levels of virus circulation.

  • COVID-19 hospital admissions have decreased since early August, while critical care admissions and deaths have remained stable. 

  • SARS-CoV-2 viral loads have remained elevated in most wastewater sites, with increasing levels in select treatment plants and stable or decreasing levels at others.

  • SARS-CoV-2 testing rate and percent positivity have remained relatively stable in recent weeks.

  • The KP.3* sublineages of JN.1* account for the majority of sequenced specimens.

National and international context

COVID-19

  • In Canada, most COVID-19 indicators continue to increase; however, trends vary across provinces and territories.  SARS-CoV-2 percent positivity continues to increase.  The JN.1* group continues to be the dominant lineage group in Canada, with the KP.3* sub-lineages being the primary sub-lineages showing growth.

  • In the USA, COVID-19 activity is elevated, with continued increases in many areas and early signs of decline in others. COVID-19 test positivity, emergency department visits, and rates of COVID-19–associated hospitalizations remain elevated in recent weeks. 
Dashboards

Respiratory virus data reporting has shifted to a spring-summer reporting schedule as of May 2, 2024. 

The Wastewater Surveillance dashboard will continue to be updated weekly. Regular weekly updates for other respiratory dashboards will resume on September 26.


Reports

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

2023/24 Weekly Respiratory Epidemiological Summaries

 

Special reports provide an in-depth summary of select topics during the current respiratory virus season.

    • 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.
