【摘要】：目的了解2015-2016年中山市感染性腹泻病原谱及其流行特征,为其防治提供科学的参考依据。方法 2015年3月-2016年10月期间对感染性腹泻哨点医院监测病例的粪便标本开展病原体检测(含细菌和病毒),对其结果进行流行病学分析。结果检测1 643份标本,共检出435份阳性,检出率为26.47%;其中病毒检出率为22.15%,细菌检出率为3.35%,混合感染检出率为0.97%。病原体以诺如病毒GII型、轮状病毒和沙门菌为主。各病原体检出率有明显的季节高峰,诺如病毒GII型检出的高峰期是8月-10月;轮状病毒检出的高峰期12月-次年3月;沙门菌检出的高峰在6月-8月。轮状病毒感染以5岁以下儿童特别是3岁以下儿童为主,诺如病毒GII型和沙门菌人群普遍易感。结论感染性腹泻的病原体以病毒为主;流行季节主要在冬春季;轮状病毒腹泻应重点关注3岁以下人群。
[Abstract]:Objective to understand the pathogenic spectrum and epidemic characteristics of infectious diarrhea in Zhongshan City from 2015 to 2016, and to provide scientific reference for its prevention and treatment. Methods from March 2015 to October 2016, pathogens (including bacteria and virus) were detected in fecal specimens of surveillance cases in sentinel hospitals of infectious diarrhea, and the results were analyzed by epidemiology. Results A total of 435 positive specimens were detected, and the positive rate was 26.47, in which the detection rate of virus was 22.1510, the detection rate of bacteria was 3.35, and the detection rate of mixed infection was 0.97. The pathogens are GII, rotavirus and Salmonella. The detection rate of each pathogen had a seasonal peak, the peak of detection of norovirus GII type was from August to October, the peak of detection of rotavirus was from December to March of the following year, and the peak of detection of Salmonella was from June to August. Rotavirus infection mainly occurred in children under 5 years old, especially in children under 3 years old. Norovirus GII and Salmonella were most susceptible to rotavirus infection. Conclusion the pathogen of infectious diarrhea is mainly virus, the epidemic season is mainly in winter and spring, and rotavirus diarrhea should focus on the population under 3 years old.
