Seroepidemiology (2018–2024) and epidemic spread of an emerging human parvovirus B19 genotype 1 (subtype 1a2) variant in Hungary, 2023/2024
An unusually large number of human parvovirus B19 (B19V) infections were reported in European countries in 2023/2024, but the genetic background of this B19V epidemic strain is unknown. In this study, there was a larger number of confirmed B19V infections (five in 2021, eight in 2023, and 59 in 2024) and higher IgG seroprevalence (41.4% in 2022 and 54.3% in 2024) in Transdanubia, Hungary, in 2024 compared to 2018-2023. A B19V genotype 1a2 variant (prototype, 1338/HUN/2024, PQ155933) with common and unique nucleotide insertions in the untranslated regions of the genome and nonsynonymous and synonymous mutations in the coding region (NS1 and VP1) could be responsible to the ongoing B19V epidemic in Europe.
