【摘要】：伤寒副伤寒是一种粪口传播的肠道传染病,是由伤寒杆菌和副伤寒杆菌甲、乙、丙引起的急性肠道传染病,是我国《传染病防治法》中规定应予“严格管理”的乙类传染病。伤寒、副伤寒在全球分布很广,全球伤寒估计每年发病1600万～1700万,死亡60万,病例主要集中在发展中国家。1990年以前,我国伤寒、副伤寒发病率在10.00/10～50.00/10万之间波动,1990年以后平均发病率降到4.08/10万～10.45/10万之间。但是1995年以后甲型副伤寒不断出现爆发流行,发病数迅速上升。全球经常出现伤寒副伤寒爆发疫情,世界各地和国内对于爆发疫情危险因素做了很多研究,主要原因是卫生设施缺乏、水源和食品污染。本研究通过描述和分析浙江省伤寒副伤寒的疫情动态,了解和掌握全省伤寒副伤寒流行特征和规律,通过爆发疫情的现场流行病学研究,探讨全省伤寒副伤寒流行的主要危险因素和防制对策。材料与方法 1950～2003年全省伤寒副伤寒疫情数据以及流动人口发病情况来自浙江省传染病疫情资料汇编;2004～2005年全省伤寒副伤寒疫情数据来自中国疾病预防控制信息系统;爆发疫情资料来自浙江省疾病预防控制中心流行病学调查材料。按人口特征、地区特点和时间分布对资料进行整理、分析。
[Abstract]:Typhoid paratyphoid fever is an acute intestinal infectious disease caused by typhoid bacillus and paratyphoid bacillus A, B and C, which is a kind of intestinal infectious disease transmitted by fecal mouth. It is a class B infectious disease which should be "strictly managed" in the Law on Prevention and treatment of Infectious Diseases in China. Typhoid fever, paratyphoid fever is widely distributed in the world. The global typhoid fever is estimated to have an annual morbidity of 16 million ~ 17 million and a death rate of 600,000. Cases of typhoid fever are mainly concentrated in developing countries. Before 1990, typhoid fever occurred in China. The incidence of paratyphoid fever fluctuated between 10.00 / 100.000 / 100,000, and after 1990 the average incidence dropped to between 40.8 / 100,000-10.45 / 100,000. But after 1995, paratyphoid A (A) continued to break out and the number of cases rose rapidly. There are frequent outbreaks of typhoid and paratyphoid fever around the world, and a lot of research has been done around the world and at home on the risk factors of the outbreak, mainly due to lack of sanitation facilities, water and food pollution. By describing and analyzing the epidemic situation of typhoid and paratyphoid fever in Zhejiang province, the epidemic characteristics and laws of typhoid and paratyphoid fever in Zhejiang Province were understood and grasped, and the field epidemiological study of the outbreak was carried out in this study. To explore the main risk factors and control measures of typhoid and paratyphoid fever in the province. Materials and methods. The epidemic data of typhoid and paratyphoid fever and the incidence of floating population came from the epidemic data of infectious diseases in Zhejiang Province from 1950 to 2003. The epidemic data of typhoid and paratyphoid fever in the whole province from 2004 to 2005 came from the China Disease Prevention and Control Information system. The data of the outbreak were collected from the Epidemiology Survey of the Center for Disease Control and Prevention of Zhejiang Province. The data were analyzed according to the population characteristics, regional characteristics and time distribution.
