摘　　要：目的分析2017-2018年四川省其他感染性腹泻病例流行病学特征,为提高监测工作质量、贯彻科学防控提供依据。方法从"中国疾病预防控制信息系统"中导出2017-2018年四川省所有其他感染性腹泻病例报告卡,使用描述性流行病学方法进行分析。结果2017-2018年四川省累计报告其他感染性腹泻病例72840例,年均发病率44.08/10万。男女性别比为1.23∶1,2岁以下幼儿和0岁组婴儿分别占病例总数的58.53%和32.31%,散居儿童占病例总数的68.35%。全省各市州地区间发病水平差异明显,成都平原及川西高原地区发病率高于其他地区。每年有2个发病高峰,夏季高峰为7-8月,冬季高峰为12月至次年1月。有明确病原学诊断的病例中,轮状病毒感染占94.67%。结论四川省其他感染性腹泻发病水平存在地区差异,2岁以下散居儿童是防控工作的重点人群,确诊病例以轮状病毒感染为主。应进一步提高病原学诊断率,在高发季节和高发地区积极开展综合防控措施。Objective To analyze the epidemic characteristics of other infectious diarrhea(other than cholera,dysentery,typhoid or paratyphoid)in Sichuan province from 2017 to 2018,and to provide evidence for its prevention and control.Methods A descriptive analysis was conducted by downloading the case-data of other infectious diarrhea in Sichuan province from 2017 to 2018 from the Chinese National Infectious Disease Reporting System.Results 72840 cases of other infectious diarrhea cases were reported from 2017 to 2018.The average incidence rate was 44.08 per 100000.The cases in children under the age of 2 accounted for 58.53%.The cases of 0 age group accounted for 32.31%with the most cases.The male to female ratio was 1.23:1.The most cases were scattered children who accounted for 68.35%.The incidence was distinctly different among the regions.The incidence of Chengdu Plain and Western Sichuan Plateau were higher than other areas.Two peaks of incidence were observed every year,in summer(from July to August)and winter(from December to next January).Confirmed cases were mainly infected by rotavirus who accounted for 94.67%.Conclusion The incidence of other infectious diarrhea in Sichuan was distinctly different among the regions.Under the age of 2 children was a high-risk group.Most confirmed cases were rotavirus infection.It is necessary to improve pathogenic diagnosis rate and strengthen the measures to prevention and control occurrence in the high risk population and areas.
