Human rhinovirus (HRV), a major cause of common cold, was associated to the hospitalization of children and adults. This cross-sectional study aimed to determine the prevalence, and genotype distribution of HRV in the patients with mild to severe respiratory infections who were negative for SARS-Cov-2.
Nasopharyngeal swab specimens (n = 356) from the patients aged 29 days to 82 years, received for the respiratory virus detection from January to December 2021, were analyzed for human rhinovirus (HRV) by RT-PCR. As a final step, genotyping was performed on obtained sequences.
A total of 37 HRV infections were identified (37/356, 10%). The highest rates of positive HRV tests were observed in February (21.6%), and January (18.9%), compared with June and August (0%). HRV-positive cases mainly appeared in winter. Among the age groups, those 2-<5 years of age had the highest detection rate (21%), however, those >55 years of age had the lowest detection rate (3%). Among HRV-positive samples, 30 (81%) were identified as type HRV-A, 5 (13.5%) as HRV-B, and 2 (5.5%) as HRV-C.
Our results suggested that HRV frequency gradually decreased with the age of patients which is more active in Iran, especially in the cold months.
人鼻病毒（HRV）是普通感冒的主要病因，与儿童和成人住院有关。本横断面研究旨在确定新型冠状病毒（SARS-CoV-2）检测呈阴性的轻至重度呼吸道感染患者中HRV的流行率和基因型分布。
收集2021年1月至12月期间年龄在29天至82岁之间、因呼吸道病毒检测而接受检测的患者的鼻咽拭子标本（n = 356），采用逆转录聚合酶链反应（RT-PCR）分析人鼻病毒（HRV）。最后，对获得的序列进行基因分型。
共鉴定出37例HRV感染（37/356，10%）。与6月和8月（0%）相比，2月（21.6%）和1月（18.9%）的HRV检测阳性率最高。HRV阳性病例主要出现在冬季。在各年龄组中，2至<5岁年龄组的检出率最高（21%），而>55岁年龄组的检出率最低（3%）。在HRV阳性样本中，30例（81%）被鉴定为HRV-A型，5例（13.5%）为HRV-B型，2例（5.5%）为HRV-C型。
我们的结果表明，HRV感染率随患者年龄增长而逐渐降低，在伊朗更为活跃，尤其是在寒冷月份。
