Alberta's Flu Season Peaks: Worst May Be Over
14 Jan
Summary
- Alberta's chief medical officer reports flu activity has peaked.
- Hospitalizations for respiratory viruses peaked on December 31.
- 74% of hospitalized flu cases were unvaccinated, urging public caution.
Alberta's chief medical officer of health indicated on Tuesday that the province is likely past the peak of a severe influenza season. An "exceptionally large" wave of influenza A, particularly the H3N2 strain, hit early in December, straining hospitals already under pressure. Hospitalizations for all respiratory viruses reached their highest point on December 31, with 995 Albertans admitted. This number has since declined, suggesting the most intense period has passed.
Despite this progress, health officials urge continued caution as Influenza B and RSV activity are now increasing. While Influenza B is typically milder and less severe in vaccinated individuals, it can still cause significant illness. RSV numbers are expected to rise through January. The healthcare system has been under considerable strain, with emergency departments remaining busy.
Data indicates that 74 percent of Albertans hospitalized with the flu this season were unvaccinated. Officials emphasize that while there are concerns about vaccine effectiveness against certain strains, immunization still significantly reduces hospitalization rates and severe outcomes. As of Tuesday, only 19 percent of Albertans had received their flu vaccination.
