From Wikipedia, the free encyclopedia
In medicine the term course generally takes one of two meanings, both reflecting the sense of "path that something or someone moves along...process or sequence or steps":
A patient may be said to be at the beginning, the middle or the end, or at a particular stage of the course of a disease or a treatment. A precursor is a sign or event that precedes the course or a particular stage in the course of a disease, for example chills often are precursors to fevers.[5]
