【摘要】：目的了解徐州市感染性腹泻的病毒病原学特点和流行特征,为制定科学的防治策略提供理论依据。方法运用Real-Time PCR方法对2013-2015年徐州市腹泻病监测哨点医院采集的粪便标本进行病毒核酸检测;采用描述性流行病学分析方法对病原学监测结果进行分析。结果 2013-2015年共检测感染性腹泻标本1 351份,病毒阳性标本数为216份,阳性率为15.99%,其中轮状病毒检出率最高,其次为诺如病毒和星状病毒。2013-2015年腹泻病毒阳性检出率分别为28.08%、10.45%、9.91%,呈现逐年递减的趋势。2013-2015年,轮状病毒和星状病毒的检出率呈逐年下降趋势,诺如病毒的检出率呈逐年上升趋势。腹泻病毒检出高峰为5~7月和9~12月。5岁以下婴幼儿较其他年龄组更易感染。结论 2013-2015年徐州市感染性腹泻的主要致病病毒为轮状病毒、诺如病毒和星状病毒,各年的病毒病原学构成有所不同;具有明显的季节流行和人群分布特点,应加强病原学监测和疾病监测预警,针对重点人群和流行毒株适时采取有效防控措施。
[Abstract]:Objective to understand the pathogenic characteristics and epidemic characteristics of infectious diarrhea in Xuzhou, and to provide theoretical basis for making scientific prevention and treatment strategies. Methods Real-Time PCR method was used to detect viral nucleic acid in stool samples collected from surveillance sentinel hospitals of Xuzhou from 2013 to 2015, and descriptive epidemiological analysis was used to analyze the results of etiological surveillance. Results A total of 1 351 infectious diarrhea specimens were detected in 2013-2015, 216 of which were positive for the virus, the positive rate was 15.99. The detection rate of rotavirus was the highest. Secondly, the positive rates of norovirus and stellate virus in 2013-2015 were 28.08% 10.45% and 9.91%, respectively. The positive rate of rotavirus and stellate virus decreased year by year in 2013-2015, and the positive rate of norovirus and rotavirus increased year by year. The peaks of diarrhea virus detection were from May to July and from September to December. Infants under 5 years old were more susceptible to infection than other age groups. Conclusion rotavirus, norovirus and stellate virus are the main pathogenic viruses of infectious diarrhea in Xuzhou from 2013 to 2015. Etiological surveillance and disease surveillance and early warning should be strengthened, and effective prevention and control measures should be taken in time for key population and epidemic strains.
