目的分析柳州市甲乙类肠道传染病发病特征及流行趋势,为肠道传染病防控提供科学依据。方法采用描述流行病学方法对柳州市2004-2012年甲乙类肠道传染病疫情资料进行统计分析。结果 2004-2012年柳州市无甲类传染病报告,累计报告乙类肠道传染病5种14 595例,年均发病率43.13/10万,发病率由2004年的88.98/10万下降到2012年的16.92/10万,呈平缓下降趋势。肠道传染病中发病率最高的是痢疾(26.83/10万),其次为未分型肝炎(9.71/10万),戊肝发病率最低。全年均有发病,5~10月份为高发季节,占报告病例的61.49%;发病在人群中形成2个高峰,一是<3岁儿童,二是15~59岁年龄段;男性发病高于女性。结论散居儿童、农民、学生为发病的高危人群;降低肠道传染病发病,关键是做好痢疾、病毒性肝炎的控制。
Objective To analyze the incidence and epidemic trend of Class A and B intestinal infectious diseases in Liuzhou and provide a scientific basis for the prevention and control of intestinal infectious diseases. Methods A descriptive epidemiological method was used to analyze the epidemic situation of Class A and B intestinal infectious diseases in Liuzhou City from 2004 to 2012. Results A total of 14 595 cases of type B enteric infectious diseases were reported in Liuzhou City from 2004 to 2012, with an average annual incidence of 43.13 / 100 000.

The highest incidence of intestinal infectious diseases is dysentery (26.83 / 100000), followed by non-segmented hepatitis (9.71 / 100000), the lowest incidence of hepatitis E. The incidence was high throughout the year, from May to October was the high incidence season, accounting for 61.49% of the reported cases; incidence peaked at 2 peaks in the population, one was <3 years old and the other was 15-59 years old; female. Conclusion The scattered children, peasants and students are at high risk of developing disease. To reduce the incidence of intestinal infectious diseases, the key is to control dysentery and viral hepatitis.
