Abstract:
Objective To determine pathogens and epidemiological characteristics of adults with acute respiratory infection (ARI) in Beijing area.Methods During 2015,a total of 2 700 cases of ARI were sampled and detected for 9 respiratory pathogens including Legionella pneumophila type1 (LP1),mycoplasma pneumoniae (MP),qrickettsia (COX),chlamydia pneumoniae (CP),adenovirus (ADV),respiratory syncytial virus (RSV),influenza virus type A and B (INFA,IFVB) and parainfluenza viruses type1,2 and 3 (PIVs) using indirect fluorescence immunoassay.Results A total of 620 cases of ARI were tested positive with positive rate of 22.97％ (620/2 700).MP had the highest prevalence followed by LP1,INFB,COX,CP,PIVs,INFA,ADV and RSV in turn.There were 109 cases found mixed infection with the proportion of 17.58％ (109/620).Mixed infection of LP1 along with MP was the most common pattern.The highest detection rate of pathogens was observed in November,whereas the lowest in April in terms of months (x2 =31.288,P＜ 0.01).Different pathogens had distinct prevalent features.The prevalence of male was significant higher than that of female (x2 =6.402,P =0.011).As for stratificated by age,the middle-aged people had the highest infection rate (x2 =9.094,P=0.059).There was no significant difference between the out-and in-patient in terms of infection rate (x2 =0.114,P=0.736).Conclusion MP,LP1 and INFB accounted for ARI of adults in Beijing area during 2015.
