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.
摘要:
在法国,在96份样本中检测献血者的细小病毒B19(B19V)DNA,以便在血浆中病毒载量较高时丢弃血浆进行分级分离.2015年1月至2024年3月,在COVID-19大流行期间,B19V阳性捐赠减少,随后在2023年强劲反弹,在2023/24年冬季出现异常高的流通量(2023年12月至2024年3月与大流行前相比增加了10倍)。随时间的变化可能与为限制SARS-CoV-2传播而实施的措施有关。
