1 817 例乌鲁木齐市儿童呼吸道感染病原体核酸检测结果分析

Abstract: Objective This study aims to analyze the pathogen types and epidemiological characteristics of children with respiratory tract infection, and provide support for accurate diagnosis, treatment, prevention and control of the disease. Methods Respiratory tract samples from 1,817 children with respiratory tract infections were detected usingrespiratory virus nucleic acid detection methods to analyze infection patterns and distribution characteristics. Results The overall positive rate of respiratory viruses was 59.05%, and respiratory syncytial virus (RSV) was the most prevalent pathogen (46.23%), there was no difference in the detection rate between boys and girls (P>0.05). Moreover, the detection rate of RSV decreases significantly with increasing age (P＜0.05). In cases of dual infection, both respiratory adenovirus (RAdV) + RSV (25.57%) and human metapneumovirus (hMPV) + RSV (21.59%) were the most common combinations.Conclusion During this winter, RSV has emerged as the predominant pathogen, posing a high infection risk to young children, especially in the context of mixed infections. Strengthened prevention, control, and monitoring measures are therefore warranted for key populations and seasons.
