伤寒和副伤寒流行强度与区域人口数、发病率、病死率、高危人群、污水系统及卫生设施、地表水系及环境污染、健康教育与人群习惯的关系密切。美国疾病预防控制中心提出、世界卫生组织报道、国际学者引用的流行区域划分法是根据伤寒和副伤寒每年发病率的高、中、低水平来划分的,该划分法不能真实反映<100万、100~1 000万、>1 000万人口数的伤寒和副伤寒高、中、低流行强度和相应区域。本研究对全球伤寒和副伤寒流行强度区域文献作一综述,分析伤寒和副伤寒流行强度、流行强度区域及其指标体系,为查明相应流行强度区域危险因素、进行风险评估和制定防控策略提供科学依据。
The prevalence of typhoid fever and paratyphoid are closely related to the regional population, morbidity and mortality, high-risk groups, sewage system and sanitation, surface water system and environmental pollution, health education and population habits. According to the CDC, WHO reports that the epidemic zoning method quoted by international scholars is divided according to the high, medium and low levels of annual incidence of typhoid and paratyphoid. The classification method can not truly reflect the "1 million, 100-1000000,> 10 million population of typhoid and paratyphoid high, medium and low prevalence and the corresponding area. This review summarizes the literature on the prevalence of typhoid and paratyphoid epidemic in the world, and analyzes the prevalence and epidemic intensity of typhoid and paratyphoid, as well as their index system. To identify risk factors in the epidemic-prone area, risk assessment and prevention and control strategies Provide a scientific basis.
