Latest flu report: Influenza B on the rise in Canada – CTV
April 13, 2023
Influenza levels have increased slightly across Canada in recent weeks – notable less for the overall numbers and more for the fact that they’re driven entirely by a rise in influenza B cases, according to Canada’s FluWatch.
The report, which comes out weekly and tracks confirmed influenza cases across the country, stated that in Week 13 of 2023, a total of 510 laboratory detections of influenza were noted across the country, numbers that aren’t out of the ordinary for this time of year.
Of these confirmed flu cases, 364 were due to influenza B and 146 were due to influenza A. Read more about the different viruses from Health Canada.
This means influenza B is currently making up 71 per cent of detections — a change from influenza A’s dominance in 2022.
The percentage of tests that came back positive for influenza were 2.4 per cent in Week 13, up from 0.8 per cent in Week 7, an increase solely due to the bump in influenza B, according to the latest FluWatch.
