所有疾病都是应该预防控制的,但是由于疾病预防控制问题的多样性、复杂性,以及受科学技术水平、预防控制手段、卫生资源等因素制约。因此,在一定区域和一定时期内只能选择最重要的疾病作为应当首要解决的问题,即疾病预防控制优先。疾病预防控制优先性分析对于疾病预防控制工作决策的重要性是不言而喻的,同样也是一件十分困难的工 All diseases should be prevented and controlled, but they are constrained by factors such as the diversity and complexity of disease prevention and control issues, as well as the level of science and technology, prevention and control methods, and health resources. Therefore, only the most important disease can be selected as the problem that should be solved first in a certain region and for a certain period of time, that is, disease prevention and control has priority. The priority analysis of disease prevention and control for the decision-making of disease prevention and control work is self-evident, and it is also a very difficult job.
