目的了解信阳地区冬春季急性下呼吸道感染(ALRT)住院儿童病毒及支原体检出率及构成特点。方法选择2013年10月至2014年3月急性下呼吸道感染的住院儿童532例,用间接免疫方法检测6种呼吸道病原体Ig M抗体(肺炎支原体、呼吸道合胞病毒、乙型流感病毒、副流感病毒、腺病毒、甲型流感INFA)。结果病原体总阳性检出率为44.54%。6种病原体检出率由高到低依次为:肺炎支原体(18.79%),呼吸道合胞病毒(12.40%),乙型流感病毒(10.52%),副流感病毒(6.90%),腺病毒(3.70%),甲型流感(0.00%)。3~6岁年龄组阳性率最高为69.56%,支气管肺炎组检出率最高为47.87%。结论引起信阳地区冬春季急性下呼吸道感染患儿的主要病原体为肺炎支原体、呼吸道合胞病毒、乙型流感病毒、副流感病毒。
Objective To investigate the prevalence and composition of virus and mycoplasma in hospitalized children with acute lower respiratory tract infection (ALRT) in winter and spring in Xinyang area. Methods A total of 532 hospitalized children with acute lower respiratory tract infection from October 2013 to March 2014 were enrolled in this study. Six kinds of IgM antibodies against respiratory tract pathogens (Mycoplasma pneumoniae, respiratory syncytial virus, influenza B virus, parainfluenza virus , Adenovirus, influenza A INFA). Results The total positive detection rate of pathogens was 44.54%. The detection rates of 6 pathogens were as follows: Mycoplasma pneumoniae (18.79%), respiratory syncytial virus (12.40%), influenza B virus (10.52%), parainfluenza virus (6.90%), adenovirus %), Influenza A (0.00%). The highest positive rate was 69.56% in 3 ~ 6 years old group, the highest detection rate in bronchopneumonia group was 47.87%. Conclusions The main pathogens causing children with acute lower respiratory tract infection in winter and spring in Xinyang are Mycoplasma pneumoniae, respiratory syncytial virus, influenza B virus and parainfluenza virus.
