This study aimed to evaluate the prevalence of human rhinoviruses (HRVs) and the emergence of enterovirus D68 (EV-D68) in children. A total of 322 nasopharyngeal swab samples were provided from children with an initial diagnosis of upper and lower respiratory tract infections. A total of 34 and 70 cases were positive for EV-D68 and HRV, respectively. The phylogenetic analysis revealed that the clades A and B are the prevalent genotypes for EV-D68 and the HRV-positive samples belong to three types including HRV-A, HRV-B, and HRV-C. The results showed that EV-D68 and HRV-C are circulating in Iran especially in the winter.
本研究旨在评估人类鼻病毒（HRV）和肠道病毒 D68（EV-D68）在儿童中的流行情况。共采集了 322 例初诊为上下呼吸道感染的儿童鼻咽拭子样本。EV-D68 和 HRV 的阳性检出率分别为 34 例和 70 例。系统进化分析显示，EV-D68 的优势基因型为 clades A 和 B，而 HRV 阳性样本则属于 HRV-A、HRV-B 和 HRV-C 三种类型。结果表明，EV-D68 和 HRV-C 正在伊朗流行，特别是在冬季。
