A novel 111‐nucleotide duplication in the G gene of human metapneumovirus

In 2017, novel human metapneumovirus (HMPV) A2b subgroup strains with a 111‐nucleotide duplication in the G gene was detected by the present team. These strains were related to previously identified HMPV A2b strains with a 180‐nucleotide duplication; however, they appeared to be different strains, produced by an independent duplication event. The recent evolution of HMPV suggests that careful monitoring of this virus is required.
