2020 Surveillance Report shows blood supply remained above target in first year of pandemic

Thursday, September 16, 2021 Tricia Abe

Canadian Blood Services recently published its annual Surveillance Report by the Epidemiology & Surveillance Department, a summary of monitoring efforts related to transmissible infection testing in donors, possible transfusion-transmitted infections in recipients, and new, emerging pathogens. Surveillance also includes monitoring of donor safety. Ongoing surveillance is a central part of ensuring the continued safety of the blood supply.

New in the 2020 report is a section on COVID-19 and donor safety. Concerns about transmission of the SARS-CoV-2 virus at donation sites prompted a number of changes. Although SARS-CoV-2 is not transmissible by blood, a variety of measures were put in place to mitigate risks brought on by the virus; not only the risk of infection for donors, volunteers and staff at donation sites, but also the risks to the adequacy of the blood supply. Yet data provided in the 2020 Surveillance Report show that the blood supply remained above target throughout the year, even as COVID-19 waves continued across Canada.

Key changes in the donation clinic to protect donors and staff during the COVID-19 pandemic. Operational changes before donors entered collection sites include the implementation of a wellness check point and a request that repeat donors complete the donor health questionnaire at home. Inside collection sites, a mandatory mask policy and capacity limits were just some of the changes implemented. Source: O’Brien S. Surveillance Report 2020. Ottawa: Canadian Blood Services; 2021.
