Introduction:This study examines the seasonal and genetic characteristics of human metapneumovirus(HMPV)in Henan from 2017 to ***:Samples from patients with acute respiratory infection(ARI)testing positive for HMPV were subjected to real-time reverse transcription polymerase chain reaction The G gene was amplified and sequenced from these samples for epidemiological and phylogenetic ***:We enrolled 2,707 ARI patients from October 2017 to March 2023,finding an HMPV positivity rate of 6.17%(167/2,707).Children under five exhibited the highest infection rate at 7.78%(138/1,774).The 2018 and 2019 HMPV outbreaks predominantly occurred in spring(March to May),with peak positivity rates of 31.11%in May 2018 and 19.57%in May 2019.A notable increase occurred in November 2020,when positivity reached a historic high of 42.11%,continuing until January *** February 2021 through March 2023,no significant seasonal peaks were observed,with rates ranging from 0%to 8.70%.Out of 81 G gene sequences analyzed,46.91%(38/81)were identified as subtype A(A2c:45.67%,37/81;A2b:1.23%,1/81)and 53.09%(43/81)as subtype B(B1:9.88%,8/81;B2:43.21%,35/81).Notably,an AAABBA switch pattern was observed in HMPV *** dominant strains were A2c111nt-dup in subtype A and B2 in subtype ***:Six years of surveillance in Henan Province has detailed the seasonal and genetic dynamics of HMPV,contributing valuable insights for the control and prevention of HMPV infections in *** findings support the development of targeted HMPV vaccines and immunization strategies.
