Abstract:
Objective To study the adenovirus infection and popular features in hospitalized respira-tory infection children of Qingdao area. Methods A total of 6 820 cases of respiratory infection from March 2011 to February 2014 in our hospital were enrolled,the average age was 5 years and 2 months old. Their ve-nous serums were collected on the first day of hospitalization,adenovirus IgM was monitored by indirect im-munofluorescence application. The adenovirus-positive rates of cases between different age groups, seasons and diseases were observed. Results Adenovirus were positive in 1 043 children,the rate was 15. 29%. The positive rate of young children group(1-3 years old) was 16. 92%,which was highest,there was statistic difference between young children group and other age groups(χ2 =12. 50,P<0. 05). Adenovirus infection rates were upward in recent years,the infection rates of winter and spring were higher than those of summer and fall,and there were significant differences between them(χ2 =28. 89,P <0. 05). The positive rate of AdV-IgM in children with severe respiratory tract infection was higher[19. 90%(877/4 408)]than that of the children with mild infection[12. 27%(296/2 412)](χ2 =64. 25,P<0. 05). Conclusion In recent years, adenovirus infection rate in Qingdao hospitalized respiratory infection children was rising,the infection rates in winter and spring were high,young children were the most vulnerable populations. The positive rate of ade-novirus infection in children with severe respiratory tract infection is higher than that of the children with mild respiratory tract infection.
