Objective: To understand the infection status and molecular types of rhinovirus (RV) among cases of Acute Respiratory Infections (ARIs) in Luohe City, Henan Province, from 2017 to 2022. Methods: From October 2017 to June 2022, clinical and epidemiological data were collected from 2 270 cases of ARIs at Luohe Central Hospital in Henan Province. Throat swab specimens were obtained from these cases. Real-time quantitative polymerase chain reaction (qPCR) was used to screen for RV-positive specimens. Subsequently, the positive samples were subjected to nested reverse transcription polymerase chain reaction (nested RT-PCR) to amplify the full-length VP1 region. Using the MEGA software, along with 169 RV reference strains recommended by the International Committee on Taxonomy of Viruses, a phylogenetic tree was constructed to determine RV types. Results: Among the 2 270 cases of ARIs, there were 1 283 male cases (56.52%). The median age (Q1, Q3) was 3 (1, 6) years, with the population under 5 years old accounting for 68.59% (1 557/2 270). RV was detected in 137 cases (6.04%), of which 68 cases (49.64%) showed co-detection with other viruses, with the most common being co-detection with enterovirus, accounting for 14.60% (20/137). The RV detection rates in the age groups of 0~4 years, 5~14 years, 15~59 years, and≥60 years were 6.42% (100/1 557), 4.69% (21/448), 3.80% (6/158), and 9.35% (10/107), respectively, with no statistically significant differences (χ2=5.310, P=0.150). The overall detection rates of RV before (2017-2019) and during (2020-2022) the COVID-19 pandemic showed no statistically significant difference (χ2=1.823, P=0.177). A total of 109 VP1 sequences were obtained, including 62 types. Among them, RV-A, RV-B, and RV-C had 42, 3, and 17 types respectively. Conclusion: RV is one of the predominant pathogens in ARIs cases in Luohe City, Henan Province, from 2017 to 2022. Multiple types of RV co-circulate without any apparent dominant type.
目的： 了解河南省漯河市2017—2022年急性呼吸道感染（ARIs）病例中鼻病毒（RV）的感染状况及其分子型别组成。 方法： 于2017年10月至2022年6月，收集河南省漯河市中心医院2 270例ARIs病例的临床和流行病学资料，并采集病例咽拭子标本，采用实时荧光定量聚合酶链式反应（qPCR）筛选RV阳性标本，随后对阳性标本使用巢式逆转录聚合酶链式反应（nested RT-PCR）扩增VP1区全长，并使用MEGA软件结合国际病毒分类委员会推荐的169条RV参考株序列构建系统进化树以确定RV分型。 结果： 2 270例ARIs病例中，男性病例1 283例（56.52%）；年龄M（Q1，Q3）为3（1，6）岁，5岁以下人群占68.59%（1 557/2 270）；137例病例（6.04%）检出RV，其中68例病例（49.64%）与其他病毒合并检出，与肠道病毒的合并检出最常见，占14.60%（20/137）。0~4岁、5~14岁、15~59岁和≥60岁年龄组中RV检出率分别为6.42%（100/1 557）、4.69%（21/448）、3.80%（6/158）和9.35%（10/107），差异无统计学意义（χ2=5.310，P=0.150）。新型冠状病毒感染疫情前（2017—2019年）和期间（2020—2022年），RV总体检出率差异无统计学意义（χ2=1.823，P=0.177）。共获得109条VP1序列，包含62个型别，其中RV-A、RV-B和RV-C三个种分别检出42、3和17个型别。 结论： RV为2017—2022年河南省漯河市ARIs病例中主要流行的病原体之一，存在多个RⅤ型别共流行，无明显优势型别。.
