The term "asymptomatic" refers to a person or individual who does not show any visible symptoms of a disease or medical condition, even though they may still be infected or ill. In medical contexts, it often pertains to conditions where a patient carries a virus or illness but does not exhibit any of the usual signs that would indicate sickness.
The word "asymptomatic" is derived from the prefix "a-" meaning "without" and "symptomatic," which comes from the Greek word "sumptōma," meaning "a symptom or occurrence." Thus, "asymptomatic" literally translates to "without symptoms."
