目的分析无锡市1991～2010年肠道传染病疫情的流行特征,进行相关预警指标探讨,为政府制定防制策略提供科学依据。方法采用Excel2000和SPSS11.0软件,用描述流行病学方法对无锡市1991～2010年报告的肠道传染病主要病种进行分析。结果无锡市1991～2010年报告甲乙类肠道传染病发病率呈下降趋势,年均发病率范围在21.22/10万～278.78/10万;主要甲乙类肠道传染病发病病种为痢疾、伤寒与副伤寒、霍乱、病毒性肝炎(甲肝和戊肝),年均发病率范围分别在17.51/10万～183.31/10万、0.39～50.12/10万、0～1.52/10万、3.14～107.46/10万;其他感染性腹泻发病率亦呈明显下降,但发病构成比有所升高。病原学监测结果表明无锡市腹泻病感染菌株以副溶血性弧菌为主(6.75%),病毒以轮状病毒(33.33%)和诺如病毒(7.95%)为主。结论肠道传染病防制虽然取得显著成绩,但仍然是无锡市应重点防制的传染病病种。
Objective To analyze the epidemiological characteristics of intestinal infectious diseases in Wuxi from 1991 to 2010 and discuss the related warning indicators so as to provide a scientific basis for the government to make prevention and control strategies. Methods Using Excel2000 and SPSS11.0 software, the epidemiological methods were used to analyze the major infectious diseases of intestine in Wuxi from 1991 to 2010. Results The incidence of Class A and B infectious diseases in Class A and Class B in Wuxi City from 1991 to 2010 showed a decreasing trend with annual average incidence ranging from 21.22 / 100000 to 278.78 / 100000. The main pathogens of Class A and B enteric infectious diseases were dysentery and typhoid fever And paratyphoid fever, cholera and viral hepatitis (hepatitis A and E), the annual average incidence ranged from 17.51 / 100000 to 183.31 / 100000, from 0.39 to 50.12 / 100000, from 0 to 1.52 / 100000, from 3.14 to 107.46 / 100,000; the incidence of other infectious diarrhea also showed a significant decline, but the incidence of constitutional ratio has increased. The results of etiological monitoring showed that the predominant strains of V. parahaemolyticus (6.75%) and rotavirus (33.33%) and norovirus (7.95%) were the predominant strains in Wuxi City. Conclusion Although the prevention and control of intestinal infectious diseases has made remarkable achievements, it is still the key infectious disease in Wuxi City.
