Surveillance of Adenovirus Respiratory Infections in Children from Osaka, Japan

Genetic Diversity of the Human Adenovirus C Isolated from Hospitalized Children in Russia (2019–2022)

“…In our current research, the majority of the HAdV-positive cases (4%, 82/1836) were detected among children younger than 2 years. A similar epidemic pattern was observed in Europe and Asia [ 22 , 25 , 26 , 27 ]. In total, co-infections of human AdVs with any other respiratory viruses were registered in 1.3% of cases during the period 2019–2022.…”

“…In the countries closest geographically to Russia, the most prevalent species of HAdV reported were as follows: genotypes C1, C2, and C5 in Japan during the period 2008–2015 [ 25 ] and HAdV-C1,2,5 during the periods 2011–2018 and 2021–2022 [ 29 , 30 ], and HAdV-C2 in China during the period 2017–2018 [ 31 , 32 ]. The HAdV-C89 genotype was also recorded sporadically in China [ 10 , 33 ].…”

Prevention Measures for COVID-19 and Changes in Kawasaki Disease Incidence

“…In this context, common age of onset in Kawasaki disease is similar to the peak ages of onset in common viral infections. 33 – 35 Moreover, common respiratory viruses were frequently detectable in the airway specimens from patients with Kawasaki disease at diagnosis. 36 , 37 Taken together our observations with these previous findings, reduced incidence of common infectious diseases in children due to the COVID-19 prevention measures may trigger the reduced incidence of Kawasaki disease.…”

Human adenovirus infections: update and consideration of mechanisms of viral persistence

“…HAdV caused 10–30% of upper respiratory infections. Both studies showed that the infections were predominately from HAdV groups C and B, with few cases resulting from group E (Ad4) infection [13,14 ▪▪ ]. Nakamura et al [14 ▪▪ ] speculated that the low rate of Ad4 infection and associated seropositivity in young children might explain the increased risk of Ad4 infections in young adults (e.g.…”
