Seroprevalence due to infection was stable around 83% in Canadian blood donors in December, although rising slightly from early fall and summer

The latest CITF-funded report from Canadian Blood Services suggests that seroprevalence due to infection was 82.68% in December 2023, in line with the 82.97% found in November 2023. Consistent with previous reports, the percentage of younger donors (ages 17-24) who had infection-acquired seroprevalence was the highest of all donor age groups.
