Answer:

A symptom is a manifestation of disease apparent to the patient himself, while a sign is a manifestation of disease that the physician perceives.

Step-by-step explanation:

The key difference between signs and symptoms is who observes the effect. For example, a rash could be a sign, a symptom, or both: If the patient notices the rash, it is a symptom. If the doctor, nurse, or anyone other than the patient notices the rash, it is a sign.

I hope this helps.
