New atypical epidemiological profile of parvovirus B19 revealed by molecular screening of blood donations, France, winter 2023/24

Marlène Guillet et al. Euro Surveill. 2024 May.

Abstract

In France, blood donations are tested in pools of 96 samples for parvovirus B19 (B19V) DNA to discard plasma for fractionation when it contains high viral loads. Between January 2015 and March 2024, B19V-positive donations decreased during the COVID-19 pandemic, followed by a strong rebound in 2023 and unusually high circulation during winter 2023/24 (ca 10 times higher December 2023-March 2024 vs the pre-pandemic period). Variations over time are probably related to measures implemented to limit SARS-CoV-2 spread.

Keywords: Blood donors; COVID-19; Parvovirus B19; non-pharmaceutical interventions; plasma-derived medicinal products.
