National and international context

Influenza

  • In Canada, indicators of influenza activity decreased in the most recent reporting week. The percentage of tests positive for influenza continues to decrease. However, trends vary regionally.  
  • In the USA, seasonal influenza activity continues to decline. 
  • In the European Union/European Economic Area (EU/EEA), decreasing trends in influenza activity are being observed in almost all countries, with half reporting having returned to baseline or low levels of intensity. 

RSV

  • In Canada, most indicators of RSV activity are stable. The percentage of tests positive for RSV is stabilizing.
  • In the USA, RSV activity is declining in most areas of the country.
  • In the EU/EEA, RSV activity remains elevated. Around one third of countries are still experiencing elevated or increasing RSV activity.

COVID-19

  • In Canada, most indicators of COVID-19 activity show signs of stabilization at low levels. The percentage of tests positive for COVID-19 is stable at the lowest recorded values seen this surveillance year (which began August 25, 2024).
  • In the USA, COVID-19 activity is declining nationally to low levels.
  • In the EU/EEA, SARS-CoV-2 activity remains at low levels in all countries.

  • COVID-19 Situation Report Archive - This report is an archive of the data previously included in the COVID-19 Situation Report dashboard,  from January 1, 2020, to August 31, 2024.

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.
