    Abstract:
    Objective: To analyze the epidemiological characteristics of human respiratory syncytial virus (HRSV) in patients with acute respiratory infection (ARIs) in sentinel hospitals of the Hubei influenza surveillance network from 2016 to 2023. Methods: ARIs samples [including influenza-like cases (ILI) and severe acute respiratory infection (SARI)] were collected from influenza surveillance sentinel hospitals in Hubei Province from 2016 to 2023, and case information was collected. HRSV virus nucleic acid typing was performed by fluorescence quantitative PCR method, and the data were collated, plotted and analyzed. Results: From 2016 to 2023, 12 779 cases of ILI and 9 166 cases of SARI were collected. The positive rate of HRSV was the highest in<5 years of age group [15.77% (168/1 065)], among which the positive rate was the highest in 2 to 5 years of age group of ILI cases [13.60% (31/228)], and the positive rate was the highest in 0 to 2 years of age group of SARI cases [25.97% (60/231)] (all P values<0.001). The positive rate of HRSV in SARI cases was 2.31%-25.97%, higher than that in ILI cases (0-13.60%) (P=0.016). HRSV was prevalent in autumn and winter from 2016 to 2020 and in spring in 2023. Alternating epidemics of HRSV virus type A and B in Hubei Province from 2016 to 2023 (dominant epidemics of type B in 2016 and 2020; dominant epidemics of type A in 2017-2019 and 2023). Conclusion: SARI and ILI patients under five years old are the main infection groups of HRSV. The seasonal prevalence characteristics of HRSV in Hubei Province from 2016 to 2023 shift from autumn and winter to spring. 目的： 分析2016—2023年湖北省流感监测网络哨点医院急性呼吸道感染（ARIs）病例人呼吸道合胞病毒（HRSV）的流行特征。 方法： 于2016—2023年采集湖北省流感监测哨点医院ARIs病例标本［包括流感样病例（ILI）和严重急性呼吸道感染（SARI）］并收集病例信息，采用荧光定量PCR法进行HRSV病毒核酸分型检测并进行资料整理、绘图和分析。 结果： 2016—2023年采集ILI和SARI病例样本分别为12 779和9 165例；<5岁年龄组HRSV阳性率最高［15.77%（168/1 065）］，其中ILI病例2~<5岁组阳性率最高［13.60%（31/228）］，SARI病例0~<2岁组阳性率最高［25.97%（60/231）］（均P<0.001），各年龄组SARI病例HRSV检测阳性率范围为2.31%~25.97%，均高于ILI病例（0~13.60%）（P=0.016）。HRSV 2016—2020年呈秋、冬季流行，2023年呈春季流行；2016—2023年湖北省HRSV病毒A型和B型交替流行（2016和2020年为B型优势流行，2017—2019以及2023年为A型优势流行）。 结论： 5岁以下SARI和ILI病例为HRSV主要感染人群；2016—2023年湖北地区HRSV季节性流行由秋、冬季流行转变为春季流行。.
