Prevalence of Parvovirus B19 Viremia Among German Blood Donations and the Relationship to ABO and Rhesus Blood Group Antigens
Background
Asymptomatic blood donors can transmit human parvovirus B19 (B19V).
Methods
We assessed the B19V prevalence among a large cohort of blood donations collected in Germany during 2015–2018.
Results
In total, 167 123 donations were screened for B19V deoxyribonucleic acid with 22 cases of viremia identified (0.013% positive). Infections peaked at a 4-year interval and the highest number of cases occurred in the summer months. All 22 infections were found in rhesus D-antigen-positive donations, suggesting a protective factor in donors who lack this antigen.
Conclusions
These findings contribute to our understanding of risk factors for B19V infection among central European blood and plasma donors
