Pellentesque dapibus efficitur laoreet. As epidemiology has evolved to cover more public health issues beyond diseases, agents can also be represented as physical or chemical factors.2, Its important to note that the epidemiologic triad is a useful tool for many diseases and health events but the model only works for those issues that have one single necessary cause. Disease prevention can be accomplished by blocking any single component of a sufficient cause, at least through that pathway. After all the pieces of a pie fall into place, the pie is complete and disease occurs.
