广东省2004～2006年感染性腹泻流行特征

EPIDEMIOLOGIC CHARACTERISTICS OF INFECTIOUS DIARRHEA IN GUANGDONG PROVINCE FROM 2004 TO 2006

[目的]分析广东省2004～2006感染性腹泻流行特征。[方法]描述性分析2004～2006广东省网络直报的感染性腹泻资料。[结果]2004～2006年广东省每年均有甲、乙、丙类感染性腹泻报告,报告发病率和死亡率均呈逐年上升趋势。霍乱、伤寒、痢疾的发病高峰在夏秋季,其他感染性腹泻的发病高峰在秋冬季。全省各市均有感染性腹泻报告,各市报告发病率相差很大。霍乱和伤寒以20～和30～岁组青年为主;痢疾和其他感染性腹泻以0～岁组为主。感染性腹泻发病数居前3位的职业依次是散居儿童、工人、农民。广东省感染性腹泻以散发为主,时有暴发。[结论]感染性腹泻在我省法定报告传染病中仍占有重要地位。今后应评估并完善感染性腹泻报告制度,加强监测与控制工作。

[ Objective] To analyed the epidemiologic characteristics of infectious diarrhea in Guangdong province from 2004 to 2006. [Methods] The information of infectious diarrhea from network direct report system from 2004 to 2006 was analyzed by descriptive epidemiology analysis. [Results] Infectious diarrhea of type Ⅰ, Ⅱ and Ⅲ was annually reported from 2004 to 2006, the incidence and mortality of infectious diarrhea reported showed to be increased year by year. The peak seasons of cholera, typhoid and dysentery were summer and autumn. Other peak seasons of other infectious diarrhea were autumn and winter. All the cities of Guangdong had reports of infectious diarrhea, and the incidences reported by cities in Guangdong had greatly difference. Patients with cholera and typhus were main youth at the age of 20 to 39 years; patients with dysentery and infectious diarrhea were main children below 10 years old. The top three occupations of patients with infectious diarrhea were dispersed children, worker and peasants. Sporadic was the main epidemic characteristic of infectious diarrhea in Guangdong, while occasionally outbreak of infectious diarrhea occurred. [Conclusion] Infectious diarrhea plays an important role in the notillable infectious disease report of Guangdong. We should evaluate and improve the infectious diarrhea report system, and strengthen surveillance and control work for infectious diarrhea.
