摘要
目的了解浙江省衢州市其他感染性腹泻的流行病学特征,探索监测系统中可能存在的问题。方法对衢州市2005-2007年疾病监测信息报告系统上报的其他感染性腹泻病例进行描述性流行病学分析。结果2005-2007年衢州市共报告其他感染性腹泻病例5413例,年发病率范围为55.39/10万～95.30/10万,发病呈逐年上升趋势。5岁以下年龄组占全部发病数的54.78%。8-9月开始其他感染性腹泻发病逐渐增加,2005年、2007年11月出现发病高峰,2006年发病高峰提前到10月;散居和托幼儿童占57.09%;其次为农民占15.72%;报告发病率居前3位的县(市、区)为开化县(146.28/10万)、柯城区(96.51/10万)、常山县(88.22/10万)。实验室诊断病例占总报告病例数的20.97%,其中轮状病毒在实验室诊断病例中占60.44%。3年共报告其他感染性腹泻暴发疫情10起,其中一起为诺如病毒感染,其他病原体均不明。结论衢州市2005-2007年其他感染性腹泻流行主要集中在0～5岁散居和托幼儿童,秋冬季是其他感染性腹泻的好发季节,各地其他感染性腹泻的报告严重不均,轮状病毒可能是影响其他感染性腹泻散在病例分布的重要因素之一。
Objective To analyze epidemiologic features of infectious diarrhea in Quzhou and provide evidence to improve the surveillance system. Methods Descriptive epidemiologic method was used to analyze the data of reported infectious diarrhea cases from routine infectious disease surveillance system during 2005-2007. Results A total of 5413 infectious diarrhea cases were reported with annual incidence rate ranged from 55.39/lakh to 95.30/lakh, which showed a increasing trend. The cases in children under 5 years old accounted for 54.78% of the total cases. During August- September, the increase of case was observed which peaked in November in 2005 and 2007 and October in 2006 ; The cases in scattered children and kindergarten children accounted for 57. 09% ; followed by the cases in farmers （ 15.72% ）. The first 3 county level areas with the incidence rate were Kaihua county（ 146.28/lakh）, Kecheng district （96.51/lakh） and Changshan county （88.22/lakh）. Laboratory confirmed cases accounted for 20.97%, among which 60.44% were rotavirus infection. Ten outbreaks of infectious diarrhea were reported during this period, and 1 was caused by Norwalk virus, the pathogens for others were unknown. Conclusion The infectious diarrhea mainly occurred in children aged 0 -5 years, the high incidence was observed in autumn and winter and the incidence in different area varied greatly.
