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。
Objective To understand the epidemiology of infectious diarrhea and its epidemiological characteristics in Zhongshan City from 2015 to 2016 and to provide a scientific reference for its prevention and treatment. Methods From March 2015 to October 2016, pathogen detection (including bacteria and viruses) was performed on the stool specimens from the surveillance cases of sentinel diarrhea sentinel hospitals and the results were analyzed by epidemiology. Results A total of 1 643 specimens were detected, 435 were positive, the detection rate was 26.47%. Among them, the detection rate of virus was 22.15%, the detection rate of bacteria was 3.35% and the detection rate of mixed infection was 0.97%. The pathogens are Norovirus GII, Rotavirus and Salmonella. The detection rate of each pathogen has a significant seasonal peak, norovirus GII detected peak is August-October; rotavirus detected peak in December-March next year; Salmonella detected peak In June-August. Rotavirus infection in children under 5 years of age, especially children under 3 years of age, Norovirus GII and Salmonella crowd susceptible. Conclusions The main pathogens of infectious diarrhea are viruses. The epidemic season is mainly in winter and spring. The rotavirus diarrhea should focus on people under 3 years of age.
