【 摘 要 】

Human adenovirus (HAdV) strains isolated from respiratory specimens of 139 children were analyzed to evaluate the endemic situation of HAdV infections in Osaka, Japan, between 2008 and 2015. The cases increased during spring and winter, and the infections were confirmed mainly in children aged ≤ 5 years, comprising 91.9% of the total population examined. Molecular typing of the isolates revealed that the most common types belonged to HAdV-B and -C. Co-infection of HAdV-C1 and -C2 was also confirmed in a case. The median age of HAdV-E cases was higher than that of the HAdV-B and -C cases. These results revealed age and seasonal distribution of respiratory HAdV infections in children from Osaka, and indicate that majority of these children might have acquired immunity through endemic HAdV infection before reaching school age.
