目的了解和掌握伤寒副伤寒流行规律,分析流行因素,探讨防制对策。方法对全省伤寒副伤寒疫情监测资料进行描述流行病学分析。结果1987～1994年浙江省伤寒副伤寒发病较高,1995～1999年下降,2000年起有逐年缓慢上升趋势。2004年局部地区出现暴发流行,使全省发病率上升明显,报告发病率达17.52/10万。其中伤寒病例2665例,副伤寒5567例。2004年全省伤寒副伤寒发病前4位分别为台州(3422例,发病率61.56/10万)、宁波(1450例,19.54/10万)、绍兴(805例,18.04/10万)和温州(1280例,17.08/10万),4个地区的报告发病数占全省总报告发病数的84.51%。贝类食品已经成为沿海地区副伤寒发病的危险因素。结论要加强包括海水产品在内的综合性监测工作,控制伤寒副伤寒的暴发流行。
Objective To understand and master the epidemic rule of typhoid and paratyphoid fever, analyze the epidemic factors and discuss the control strategies. Methods Epidemiological analysis of the surveillance data of typhoid and paratyphoid fever in the whole province was carried out. Results The incidence of typhoid and paratyphoid fever in Zhejiang Province during 1987-1994 was relatively high, decreasing from 1995 to 1999, and gradually increasing year by year since 2000. Outbreaks occurred in some areas in 2004, causing a significant increase in the incidence in the province with a reported incidence rate of 17.52 / 100,000. Among them, there were 2665 cases of typhoid fever and 5567 cases of paratyphoid fever. Four cases of typhoid and paratyphoid fever in the province in 2004 were Taizhou (3422 cases, incidence 61.56 / 100000), Ningbo (1450 cases, 19.54 / 100000), Shaoxing (805 cases 18.04 / 100000) and Wenzhou 1280 cases, 17.08 / 100000). The number of reported cases in 4 regions accounted for 84.51% of the total reported cases in the province. Shellfish has become a risk factor for the onset of paratyphoid in coastal areas. Conclusion Comprehensive monitoring including marine products should be stepped up to control the outbreak of typhoid and paratyphoid fever.
