Abstract

Background

Although the SARS-CoV-2 virus is transmitted mainly through the respiratory tract, possible transmission by transfusion from asymptomatic carriers should be explored. As yet there are no reports of transfusion transmission of COVID-19. Haemovigilance findings within a three-month surveillance period during the new coronavirus pandemic are presented.

Materials and methods

Due to great demand and shortage, blood sessions in outpatient facilities were organized during the high prevalence period of COVID-19, alongside a national plan to monitor the evolving public health situation by random molecular screening of high-risk groups of the population. Haemovigilance protocols were implemented as well as surveillance for any COVID-19 case reported post-transfusion. A 14-day quarantine and follow-up molecular and antibody testing of any COVID-19 positive case was obligatory.

Results

Post-donation, post-transfusion information and molecular testing of swab samples collected from three asymptomatic donors at risk for COVID-19, revealed the case of an immunosupressed patient who had been transfused with whole blood derived platelets from a donor subsequently diagnosed with COVID-19. The recipient exhibited no symptoms of the disease. Molecular and antibody testing results were negative.

Conclusion

Haemovigilance provided information supporting the absence of transfusion transmission of COVID-19, thus strengthening the hypothesis that, even if it cannot yet be definitively ruled out, COVID-19 is not transmitted through blood transfusion. As of early June 2020, a perfect test does not exist, therefore haemovigilance along with the implementation of strict proactive measures is crucial to identify eluding asymptomatic individuals and ensure blood safety during the pandemic.
