Note (General)Background: Acute lower respiratory tract infections (ALRIs) are the most common disease for hospitalized children in Japan. The aim of this study was to identify viruses in children hospitalized for ALRIs and to demonstrate epidemiologic and clinical characteristics in Japan. Methods: During a 2-year period from February 2013 to January 2015, we collected nasopharyngeal swab specimens from almost all hospitalized children with ALRIs in Nagasaki, a regional city of Japan, and its environs. Viruses were detected by multiplex polymerase chain reaction from these samples. Results: We detected one or more viruses from 259 (69%) of 374 patients, 227 of whom were infected with a single virus, 30 with 2, and 2 with 3 viruses. Detected viruses in this study were rhinovirus (46.4%), respiratory syncytial virus (29.7%), human metapneumovirus (6.8%), parainfluenza virus (5.5%), enterovirus D68 (3.4%), influenza virus (2.7%), adenovirus (2.4%), bocavirus (2.0%) and Coxsackie virus (1.0%). We detected a seasonal shift in respiratory syncytial virus outbreaks from the 2013?2014 to the 2014?2015 seasons. There was no significant difference in clinical course and severity among those viruses. Patients with a history of asthma or underlying diseases were older and more frequently required oxygen therapy than previously healthy patients. Conclusions: Viral etiology in hospitalized children with ALRIs in Nagasaki, Japan, was similar to that in many other countries. Enterovirus D68, which was recently recognized as a causative agent of severe ALRIs, was also identified in this study area. Severity of ALRIs may depend on underlying disease rather than type of etiologic virus.
