2015-2016年某区部队呼吸道传染病病原监测数据分析

Analysis of surveillance data of respiratory infectious diseases in a certain area from 2015 to 2016

目的监测某区部队急性呼吸道传染病病原活动水平和流行动态,了解急性呼吸道传染病的病原谱构成,为部队卫生防病工作提供科学依据。方法对某区疾控中心和基层医院采集的流感样(influenza-like illness,ILI)病例进行监测分析,并完成病原谱的构建。结果某区疾控中心与基层医院共接收流感样病例鼻咽拭子1 161份,PCR检出阳性312份,总阳性检出率26.87%。其中疾控中心接收鼻咽拭子样本570份,检出阳性145份,阳性检出率25.44%;样本采集量于1、2月达到高峰。阳性率在3月左右达到高峰,比ILI病例高峰出现时间延后1~2个月。基层医院接收样本591份,检出阳性167份,阳性检出率28.26%。样本采集量近3月左右达到高峰。阳性率在2月左右达到高峰。病原主要以乙型流感病毒和甲型流感病毒为主,腺病毒及其他病毒亚型为辅,其中甲型以H3和H1N1两种亚型为主。结论本研究初步描述了某区部队发热病例常见呼吸道病毒病原谱,分析了呼吸道病毒性感染的流行病学分布,将对部队呼吸道病毒性疾病的临床诊治、传染病防控提供基础资料和参考。

Objective To monitor the level and epidemic trends of acute respiratory infectious diseases in a certain area, and to understand the pathogenic spectrum of acute respiratory infectious diseases, and to provide scientific basis for the prevention and control of the disease. Methods To the district center for disease control and primary hospital acquisition of influenza like cases （influenza- like illness, ILl） was monitored and analyzed, and complete the construction of pathogens. Results The district CDC and the primary hospital received a total of 1 161 samples of influenza like cases of nasopharyngeal swab, PCR detected 312 positive samples, the total positive detection rate of 26. 87%. Among them, the CDC received 570 samples of nasopharyngeal swab samples, 145 positive samples were detected, the positive rate was 25.44% , the sample collection was 1, and the peak value was reached in February. The positive rate reached a peak in March, more than 1 to 2 months later than the peak of ILl ca- ses. At the basic level, 591 samples were received, 167 positive samples were detected, and the positive rate was 28.26%. Sample collection of nearly March to reach the peak. The positive rate was concentrated in February and reached the peak. Mainly by the main pathogen of influenza and influenza A, adenovirus and other viral subtypes, including H3 and H1 N1 of the two sub- types of the main. Conclusion This study preliminarily describes a region of troops fever cases of common respiratory viruses pathogenic spectrum, analysis of the distribution of the epidemiology of respiratory tract viral infection, which will be our army for respiratory viruses of the clinical diagnosis and treatment of the disease, infectious disease prevention and control to provide basic data and reference.
