ABSTRACT
To investigate the molecular characteristics of human respiratory syncytial virus (HRSV) detected in Gyeonggi Province from 2015/16 to 2017/18, 2331 specimens from patients with sporadic acute respiratory illness and 85 specimens from four HRSV outbreaks in the postpartum care center were analyzed by real-time reverse transcription PCR. HRSVs were detected in 97 of the 2416 (4.0%) specimens, and among the positive specimens, 38 (39.2%) were identified as HRSV-A and 59 (60.8%) as HRSV-B. During the study periods, HRSV-B predominated in all seasons, except in 2016/17 during which HRSV-A predominated. Depending on the age groups, HRSV prevalence was the highest in 0- to 2-year-old patients. Comparison of noninfected subjects with HRSV-infected subjects revealed that HRSV infection more frequently resulted in fever, nasal obstruction, and wheezing, although the frequency of sore throat was low; however, comparison of the symptoms between HRSV-A- and HRSV-B-infected patients revealed no significant differences in symptoms. Phylogenetic analysis showed that all HRSV-A patients had an ON1 genotype, and all HRSV-B patients had an BA9 genotype. These results provide a valuable reference regarding the circulating pattern and molecular characterization of HRSV. Continuous monitoring will be essential to detect newly emerging HRSV genotypes.
