传染性腹泻和其它肠道传染病的最终控制,最好是通过水源、卫生和教育的改进而完成。由于资源的限制和其它优先项目的竞争,这个目标在最近的将来在世界的许多地区是不能实现的。预防的补充手段是发展能提供长期保护作用的菌苗。一个肠道菌苗有效的例子就是脊髓灰质炎活疫苗或灭活疫苗的发展,它显著地降低了这种传染病在世界范围的发病率。 The ultimate control of contagious diarrhea and other enteric diseases is best accomplished through improvements in water sources, sanitation and education. This goal, in the near future, can not be achieved in many parts of the world because of resource constraints and competition from other priority projects. A complementary means of prevention is to develop bacterins that provide long-term protection. An example of an effective gut vaccine is the development of live or inactivated polio vaccine that significantly reduces the worldwide incidence of this infectious disease.
