↵* Data accurate as of Jan. 12, 2021. Excludes 25 cases who resided outside of the VCH region but worked in or attended school in person in the VCH region. Although VCH followed up on all school cases, clusters and exposures at schools within the VCH region, long-term follow-up of individual cases is typically completed in the health authority in which the individual resides. Therefore, complete information from long-term follow-up (e.g., hospitalization data) was available only for individuals residing within the VCH region.
