摘要： 目的 分析重庆市其他感染性腹泻流行病学特征,为制订防控措施提供科学依据。方法 通过中国疾病预防控制信息系统“传染病监测系统”收集2009-2019 年重庆市其他感染性腹泻疫情资料,运用描述性流行病学方法进行分析。结果 2009-2019 年重庆市报告其他感染性腹泻病例共359 471 例,死亡14 例,年均报告发病率110. 10/ 10 万,年报告发病率在69. 75/ 10 万~156. 76/ 10 万间,报告发病率整体呈现上升趋势(χ2趋势= 986. 165,P<0. 001)。每年呈现7-9 月和11 月-次年1 月两个高峰期。年均报告发病率位居前三位的地区为沙坪坝区(354. 89/10 万)、南岸区(260. 31/ 10 万)和垫江县(205. 11/ 10 万)。人群分布方面,男性报告发病例数(200 968 例)和发病率(121. 10/ 10 万)均高于女性;年龄上以5 岁以下人群报告病例数占比最高(68. 53%,246 347/ 359 471);职业上以幼托儿童(66. 01%,237 279/ 359 471)和农民(12. 09%,43 455/ 359 471) 占比较高。感染的病原体以病毒为主(占98. 29%);病毒和细菌型病例分别以轮状病毒感染(占94. 05%)和沙门氏菌感染(占52. 31%)为主。共报告其他感染性腹泻聚集事件189 起,报告发病数4 363 例,无死亡病例。结论 重庆市其他感染性腹泻流行形势较为严峻,应采取综合干预措施有效控制暴发和流行。

Abstract: Objective To analyze the epidemiological characteristics of infectious diarrhea other than cholera, dysentery,typhoid and paratyphoid in Chongqing for evidence to scientifically plan prevention and control strategies. Methods The data were collected from the Infectious Disease Monitoring System under the Infectious Disease Report Information System in China on other infectious diarrhea cases reported in Chongqing from 2009 to 2019. Descriptive epidemiology was used to analyze the infection behavior. Results A total of 359 471 other infectious diarrhea cases were reported from 2009 to 2019 (total population incidence:110. 10/ 100 000), and 4 deaths were reported. The annual reporting rate was between
69. 75/ 100 000 and 156. 76/ 100 000, and tended to increase yearly(χ2tendency = 986. 165,P<0. 001). Prevalence was peaked between July and September, and November and January of following year. Higher infections reported each year were Shapingba (354. 89/ 100 000), Nanan(260. 31/ 100 000) and Dianjiang (205. 11/ 100 000). Infection reported in population was higher in males(200 968 cases; incidence rate: 121. 10/ 100 000) than in females. Population aged under 5 years were most affected (68. 53% ; 246 347/ 359 471), particularly in children in nursery schools(66. 01% ; 237 279/359 471), followed by farmer (12. 09% ; 43 455/ 359 471). Virus(98. 29% ) was the dominant pathogen. Cases with rotavirus and Salmonella were 94. 05% ,52. 31% , respectively. A total of 189 aggregation events of other infectious diarrhea
were reported, with reported cases of 4 363. No death occurred. Conclusion The situation of other infectious diarrhea in Chongqing still remains very serious. Comprehensive intervention measures should be taken to effectively control the outbreak and epidemic.
