Respiratory virus activity in BC

Reporting period:  May 25-31, 2025 (Epi-week 22) - Open the weekly summary as a PDF

The 2024/25 respiratory virus season has ended and reporting has moved to a spring-summer schedule. During this time, the Wastewater Surveillance dashboard will be updated weekly. The Facility Outbreaks dashboard will pause until fall. All other viral respiratory dashboards will be updated on the first Thursday of the month.

COVID-19 activity is low but increasing; influenza and RSV remain low.


Influenza

  • Influenza test positivity continues to decrease and is at low levels. Wastewater viral loads are stable and low across BC.

RSV 

  • RSV test positivity and wastewater viral loads are stable and low across BC. 

COVID-19

  • SARS-CoV-2 test positivity and wastewater viral loads are increasing but remain at low levels. Severe outcomes are low overall, but hospital admissions are showing early signs of an increase.

Health care visits

  • The proportions of emergency department and primary care visits for respiratory illness continue to decrease and are at low levels.

National and international context

Influenza

  • In Canada, indicators of influenza activity decreased in the most recent reporting week. The end of the influenza season at the national level occurred in week 19 (week ending May 10, 2025).  
  • In the USA, seasonal influenza activity is low. 
  • In the European Union/European Economic Area (EU/EEA), most reporting countries have returned to baseline or low levels of influenza activity. 

RSV

  • In Canada, most indicators of RSV activity are low and stable.
  • In the USA, RSV activity has declined to low levels.
  • In the EU/EEA, RSV activity has fallen to low levels in all reporting countries.

COVID-19

  • In Canada, most indicators of COVID-19 activity are low and stable.  
  • In the USA, COVID-19 wastewater activity, emergency department visits, and laboratory percent positivity are at very low levels.  
  • In the EU/EEA, SARS-CoV-2 activity remains low in all countries. There appears to be a slowly increasing trend in the proportion of positive tests in non-sentinel laboratory-based surveillance in a number of countries. No significant impact in secondary care indicators or in COVID-19 deaths has been observed so far.  

Dashboards

Respiratory virus data reporting has shifted to a spring-summer reporting schedule.

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

COVID-19 Situation Report

  • 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.
