Fig. 1. Phylogenetic trees based on the second hypervariable region of the G protein. Trees using the neighbor-joining method with maximum composition likelihood in Mega X by bootstrapping (1000 iterations). Only bootstrap values ≥ 50% are shown for each tree. Our stains were expressed as name of strains/country/isolated case number/collected year. The control strains used for comparison were expressed as accession numbers registered in the Genbank. (A) RSV-A (All cases are classified as ON1 genotype, n = 11), (B) RSV-B (All cases are classified as BA9 genotype, n = 15).

RSV = respiratory syncytial virus.
