Human rhinovirus (HRV) typing by semi-nested reverse-transcription polymerase chain reaction and sequencing of the 539 bp fragment of the VP4/VP2 genes amplified from 297 clinical specimens. (A) Phylogenetic tree constructed using the maximum likelihood method in MEGA version 6.0 software to identify the genotypes of HRV in the enrolled clinical specimens. The orange branches represent HRV-A, the blue branches HRV-B, and the red branches HRV-C. (B) Numbers of patients infected with each genotype of HRV-A among the 148 patients. C: Numbers of patients infected with each genotype of HRV-B among the 20 patients. D: Numbers of patients infected with each genotype of HRV-C among the 129 patients
