Epidemical features of HAdV-3 and HAdV-7 in pediatric pneumonia in Chongqing, China.
Human adenoviruses (HAdV) of species B, C, and E (HAdV-B, -C, -E) are frequent causative agents of acute respiratory infections worldwide. No specific analysis has been done on the epidemiological and clinical features of HAdV in pediatric pneumonia in China. Nasopharyngeal aspirates were collected from hospitalized children with pneumonia from June 2009 to May 2014. ⋯ Temporal patterns showed that, except for a simultaneous outbreak of HAdV-3 and HAdV-7 during the years 2010-2011, HAdV-7 and HAdV-3 were alternately predominant, and the dominance shifted to HAdV-3 after 2014. Identification of the predominant HAdV genotypes and their epidemical features is useful for determining preventive strategies. HAdV-7 associated severe pneumonia needs to be considered with high priority in clinical practice.
