CAUSES OF DISEASE AND CAUSES OF DEATH

In the early nineteenth century, the causes of disease and the causes of death that physicians identified were both sufficient causes of par ticular events. By the end of the century, physicians were no longer i nterested in sufficient causes of individual disease episodes - instea d they sought necessary causes that were shared by all cases of each p articular disease. However, there was no parallel change in causes of death; even today, the causes of death we identify are sufficient caus es of particular events. Why are causes of disease no longer similar t o causes of death?
