Respiratory virus activity in BC

Reporting period:  January 4-10, 2026 (Epi-week 1)​​ - O​pen the ​week​l​y summary as a PDF

Current respiratory activity is measured in consideration of recent past respiratory seasons.​

Influenza activity is hi​​gh; RSV is moderate; COVID-19 is low.

Influenza

  • Influenza test positivity decreased this week in children and adults but remains at high levels in both age groups. Wastewater viral loads are increasing or remain stable at varying levels.

RSV 

  • RSV test positivity continues to increase in adults and remains at moderate levels in all age groups. Wastewater viral loads are increasing or remain stable at low-to-moderate levels.

COVID-19

  • SARS-CoV-2 test positivity is stable at low levels. Wastewater viral loads are decreasing or remain stable at low-to-moderate levels in most sites. Severe outcomes remain low.

Health care visits

  • The proportions of emergency department and primary care visits for respiratory illness are elevated in adults and at moderate levels among children. Trends are comparable to prior seasons.​

National and international context

Influenza

  • In Canada, all indicators of influenza activity are high but were either stable or decreased in the most recent reporting week.  
  • In the USA, seasonal influenza activity remains elevated across the country. 
  • In the European Union/European Economic Area (EU/EEA), influenza circulation continues to increase in most countries, although for some countries, the peak appears to have passed. All age groups are affected. Increases in hospitalisation are observed in many countries, primarily in adults aged 65 years and above. ​

RSV

  • In Canada, indicators of RSV activity are increasing slowly.
  • In the USA, RSV activity is elevated in many areas of the country with emergency department visits and hospitalizations increasing among children 0-4 years old.
  • In the EU/EEA, RSV circulation continues to slowly increase in several countries. Hospital data show rising RSV-related admissions in a few countries, primarily among children under five years of age. RSV-related hospitalisations are at levels below those observed at this time in the past four seasons.​

COVID-19

  • In Canada, some indicators of COVID-19 activity increased in the most recent reporting week.  
  • In the USA, COVID-19 activity is low but increasing nationally. 
  • In the EU/EEA, SARS-CoV-2 circulation continues to decrease in all age groups, and the impact on hospitalisations is currently limited.​

Survey

We are interested in knowing if you have found the information on the Wastewater Surveillance dashboard​ useful. You can complete a five to 10-minute survey on your experience​ for a chance to win a small gift.

  • ​​2022/23 Respiratory Season Surveillance Report
    • ​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.

For detailed information about the update to the surveillance system and impact of the changes, read the technical document: BC COVID-19 Surveillance System Update: Infection episode-based approach​
