[Diagnostic aspect of symptoms] Similarly, one symptom may be common to many diseases, one symptom may be related to only one disease, many symptoms may be associated with only one disease, and many symptoms may be common to many diseases.
One symptom i.e. jwara can be considered common to many diseases that have irregular onset, while santapa (elevated temperature) is considered a symptom of only one disease i.e. jwara.
Irregular onset (and similar other symptoms) appear in the case of jwara, while similar symptoms also occur in shwasa (dyspnea), hikka (hiccups), and other similar diseases.

[Therapeutic considerations] A single therapy can subside many diseases as well as a single disease. Multiple therapies may be needed to subside many diseases, whereas one disease could require multiple therapies to cure.
