Abstract

Abstract

Objective To analyze the pathogenic epidemiological characteristics of acute lower respiratory tract infection(ALRTI) in children in Gansu Province from 2012 to 2015. Methods The surveillance data of 458 children infected with ALRTI in 10 sentinel hospitals in Gansu province from 2012 to 2015 were collected, and infection status and epidemiological characteristics of each virus and bacteria were analyzed by descriptive study methods. Results The male to female ratio of the 458 children with ALRTI was 1.81:1, and the positive detection rate of the virus was 33.62%(95% CI:29.28%-37.97%), among which the positive detection rate of respiratory syncytial virus was the highest(12.23%).The positive detection rate of bacteria was 24.84%(95% CI:20.04%-29.65%), among which the positive detection rate of streptococcus pneumoniae was the highest(18.47%).There was significant no difference in the positive detection rate of virus and bacteria between children of different genders(P > 0.05).There was significant no difference in the positive detection rate of virus among children of different age groups(χ²=5.980, P=0.050), but the positive detection rate of bacteria was different(χ²=12.078, P=0.002).Positive detection rates of virus infection and bacterial infection were different in distinct seasons(all P < 0.05). By using logistics regression analysis, season, age and sentinel hospital were the influencing factors of ALRTI virus infection in children(allP < 0.05), and sentinel hospital and years were the influencing factors of ALRTI bacterial infection in children(allP < 0.05). Conclusion Respiratory syncytial virus, influenza virus and parainfluenza were the main causes of ALRTI virus infection in children aged 0-14 years in Gansu province, and the main bacterial infections were streptococcus pneumoniae and haemophilus influenzae, the number of virus infection was more than that of bacterial infection. Viral and bacterial infection had the same peak incidence.
