Weekly influenza reports

FluWatch Summary

February 3, 2019 to February 9, 2019 (Week 6)

  • Influenza activity in Canada continues to decline slowly. Influenza activity is past the peak in most regions in western Canada, but continues to circulate in eastern regions.
  • At the national level, most indicators of influenza activity declined in week 06.
  • Influenza A(H1N1)pdm09 continues to be the most common influenza virus circulating in Canada. There is currently very little influenza B circulation compared to previous seasons.
  • The higher proportion of laboratory detections, hospitalizations and outbreaks among people in younger age-groups reflects the increased impact of A(H1N1)pdm09 on people under 65 years of age compared to the past two seasons.
