The BC COVID-19 Modelling Group works on rapid response modelling of the COVID-19 pandemic, with a special focus on British Columbia and Canada.

The interdisciplinary group, working independently from Government, includes experts in epidemiology, mathematics, and data analysis from UBC, SFU, UVic, and the private sector, with support from the Pacific Institute for the Mathematical Sciences.

COVID Model Projections - November 23, 2022

The BC COVID-19 Modelling team issued their twenty-sixth report on the status of COVID-19 in British Columbia (November 23rd, 2022). Omicron continues to be dominated by BA.5* variants, particularly descendants like BQ.1* that carry many mutations that reduce antibody recognition. BQ.1* has risen to an estimated current frequency of 50% in BC and in Canada. Nevertheless, case numbers are rising and falling in a manner that depends less on these variants and more on population-level immunity and the waning of this immunity. This is good news, suggesting that population-level immunity is largely protective against BQ.1* as well.

COVID Model Projections - October 5, 2022

The BC COVID-19 Modelling team issued their twenty-fifth report on the status of COVID-19 in British Columbia (October 5th, 2022). The BA.5-driven Omicron wave persists with high rates of infection. The prolonged nature of the BA.5 wave is consistent with waning of immunity from infections and vaccinations early in the year. Future projections predict a rise in cases, even without new variants that are better able to evade immunity. Underreporting of cases is extremely high, with ~100-fold more infections currently than reported cases.

The BC COVID-19 Modelling team issued their twenty-fourth report on the status of COVID-19 in British Columbia (August 17th, 2022). This report shows that the Omicron BA.5 wave has peaked across much of Canada. Nevertheless, risks of infection remain high, with infections likely 100-fold more common than reported cases at present.

The BC COVID-19 Modelling team issued their twenty-second report on the status of COVID-19 in British Columbia (May 18th, 2022). This report focuses on the ongoing Omicron BA.2 wave, which appears to have peaked in BC and elsewhere in Canada, and examines data for new variants.
