Download in PDF format
(1.9 MB, 12 pages)

Organization: Public Health Agency of Canada

In this Respiratory Virus Report, the number of detections of coronavirus reflects only seasonal human coronaviruses, not the novel pandemic coronavirus (SARS-CoV-2) that causes COVID-19. For information on COVID-19, see the Coronavirus disease (COVID-19): Outbreak update

Overall Summary

Detections of seasonal respiratory viruses have dropped sharply since the end of December 2021. In recent weeks, activity of all seasonal respiratory viruses has stabilized and is within or below expected levels for this time of year.

  • Respiratory syncytial virus (264 detections; 2.5% positive) is the most common seasonal respiratory virus detected in Canada, but activity is below expected levels for this time of year.
  • Detections of other respiratory viruses are low.
  • The number of tests performed for each virus is within expected levels.
    • Due to the current COVID-19 pandemic, changes in laboratory testing practices for the past week may affect the comparability of data to previous weeks.
  • 31/34 sentinel laboratories reported surveillance data.

The data in the RVDSS report represent surveillance data available at the time of writing. Data not collected by reporting lab denoted by N.C.

The reporting laboratory previously listed as CHEO - Ottawa is now listed as EORLA to better reflect data submitted by this provider.

Specimens from Yukon (YT) are sent to reference laboratories in British Columbia and reported results reflect specimens identified as originating from YT.

Results from British Columbia comprise of specimens from the following sites: BC Children's and Women's Hospital, Children's and Women's Hospital Laboratory, Fraser Health Medical Microbiology Laboratory, Island Health, Providence Health Care, Powell River Hospital, St. Paul's Hospital, Vancouver General Hospital, Victoria General Hospital, BCCDC Public Health Laboratory, Interior Health Authority sites and Northern Health Authority sites.

Delays in the reporting of data may cause data to change retrospectively.

For British Columbia, only data from subtyped influenza A specimens are included in the weekly number of influenza detections. The sum of A(H1N1)pdm09, A(H3), and A(UnS) positive results may not equal the sum of total Flu A positive results.
