Molecular epidemiology of human metapneumovirus before and after COVID-19 in East Japan in 2017-2022
In this study, we analysed the sequences of hMPV isolates obtained from 2017 to 2022 in Tokyo and Fukushima, i.e., before and after COVID-19. Subgroup A hMPVs were detected in 2017 to 2019, and most cases were A2c111nt-dup, suggesting there was continuous momentum of this clade, identical to the global situation. Subgroup B, but not subgroup A, viruses were detected in 2022, after the COVID-19 peak. Phylogenetic analysis showed that these resumed subgroup B viruses were closely related to the viruses detected in 2013 to 2016 in Yokohama and in 2019 in Fukushima, suggesting a reappearance of local endemic viruses in East Japan.PMID:38171847 | DOI:10.7883/yoken.JJID.2023.350
