Pervasive is an adjective used in the medical field to describe a condition or symptom that is widespread or present in various parts of the body. The term is derived from the Latin word "pervasus," which means "spread through."

Etymology

The term "pervasive" comes from the Latin word "pervasus," which is the past participle of "pervadere." "Pervadere" means "to spread through" or "to permeate," and it is a combination of "per-" (through) and "vadere" (to go).
