Respiratory Virus Report, Week 44 - ending November 5, 2022

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

Respiratory virus activity has increased in recent weeks in Canada, and activity of several viruses is above expected levels.

  • Overall influenza activity is increasing and above expected levels for this time of year (2,234 detections; 11.7% positive). Influenza activity is above the seasonal threshold of 5% of tests positive, indicating the beginning of the influenza epidemic at the national level.
    • Influenza activity is increasing across Canada, with nearly all regions reporting over 5% of tests positive.
    • Influenza A accounts for nearly all influenza activity in Canada.
  • Overall respiratory syncytial virus activity is increasing and is above expected levels for this time of year (1,309 detections; 7.8% positive). Level of activity is variable across regions (range: 1.8%–20.1% positive).
  • Activity of other respiratory viruses is relatively stable and near expected levels for this time of year.
  • 32/34 sentinel laboratories reported surveillance data.

The data in the RVDSS report represent surveillance data available at the time of writing. Data missing from the current week are denoted by N.R. Data not collected by reporting lab denoted by N.C.

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: Children's and Women's Hospital Laboratory, Fraser Health Medical Microbiology Laboratory, Island Health, Providence Health Care, Vancouver Coastal Health sites, Victoria General Hospital, BCCDC Public Health Laboratory, Interior Health Authority sites and Northern Health Authority sites.

Due to different testing protocols of laboratories across Canada, influenza A subtype detection counts may not be included in total influenza A detection counts. Total influenza A and B positive counts are used to calculate percentage of tests positive.

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

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.

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: Children's and Women's Hospital Laboratory, Fraser Health Medical Microbiology Laboratory, Island Health, Providence Health Care, Vancouver Coastal Health sites, Victoria General Hospital, BCCDC Public Health Laboratory, Interior Health Authority sites and Northern Health Authority sites.

Due to different testing protocols of laboratories across Canada, influenza A subtype detection counts may not be included in total influenza A detection counts. Total influenza A and B positive counts are used to calculate percentage of tests positive.

Delays in the reporting of data may cause data to change retrospectively. Due to these delays, the sum of weekly report totals do not add up to cumulative totals.
