Polyomaviruses (PyV) WU and KI are reportedly associated with respiratory tract disease (RTD) worldwide but their incidence is unclear in Japan. In a 2 year prospective study, WU/KIPyV were detected in 48 (13.9%) and in five (1.4%) of 345 children hospitalized with lower RTD, respectively. The seasonal distribution was observed in spring and early summer. Other respiratory viruses were co-detected in 51% of PyV-positive patients, but eight (2.3%) of the WUPyV-positive patients were negative for other known pathogens.
据报道,多瘤病毒(PyV)WU和KI在全球范围内与呼吸道疾病(RTD)相关,但在日本其发病率尚不清楚。在一项为期2年的前瞻性研究中,在345名因下呼吸道疾病住院的儿童中,分别有48名(13.9%)和5名(1.4%)检测到WU/KI PyV。观察到其季节性分布在春季和初夏。51%的PyV阳性患者同时检测到其他呼吸道病毒,但8名(2.3%)WU PyV阳性患者对其他已知病原体检测呈阴性。
