Abstract:
Objective To analyze the epidemiology of outbreaks and epidemic characteristics of respiratory diseases caused by human adenovirus in China so as to provide some data for its epidemic and outbreak control and clinical diagnosis .Methods Data on respiratory adenovirus outbreaks and surveillance from 1997 to 2015 was collected from PubMed, China National Knowledge Infrastructure (CNKI), and Wanfang Databases.All the data was analyzed according to the descriptive epidemiology , including the time , area and population distribution .Clinical data and the serotypes of adenovirus were also analyzed.Results From 1997 to 2015, the epidemical serotypes of adenovirus included 1 to 7, 11, 14 and 55 in China, and the dominating serotypes were 7 and 3, which accounted for 62.33％(599/961) and 24.97％(240/961)of the total cases of outbreaks, and for 36.79％(312/848) and 53.18％(451/848) of the total cases of surveillance.The peaks of annual outbreaks were in 2004 and 2013, which made up 41.12％(2212/5380) and 16.49％(887/5380)of the total outbreak cases in this study .Most of the surveillance cases years occurred in 2010 and 2011, which accounted for 17.59％(297/1688) and 17.77％(300/1688) of the total cases of surveillance .The seasonal distribution of the outbreaks was characterized by the highest possibility in spring and winter .Outbreaks of respiratory adenovirus were reported by 12 provinces or municipalities .The number of reported outbreaks related to serotype 3 was the largest in Jiangsu Province, which made up 58.33％(140/240) of the total.Most of the reported cases related to serotype 7 occurred in Hubei Province, which made up 67.41％ (333/494) of the total.Most of cases were found in Peking and Jiangsu , which accounted for 57.56％(971/1687)and 32.42％(547/1687)of the total positive cases respectively.The high-risk populations were children and new recruits , who accounted for 73.97％(2907/3930) of the total.The clinical features of adenovirus infection were fever (63％-100％),sore throat (31.9％-100％), pharyngeal hyperemia (60％-100％) and cough (5.88％ -100％).Conclusion Human respiratory adenovirus has become one of the main pathogenic microorganisms that induce acute respiratory diseases in schools and in the military in China , so human adenovirus and related respiratory disease should be monitored in such populations .The epidemiological characteristics of different types of respiratory adenovirus and the patterns of spread should be analyzed in order to reduce morbidity and mortality.
