What does prodrome mean?
A prodrome is a preliminary symptom or sign that a disease or other condition is about to develop. It does not usually identify the condition by itself; instead, it marks a stage before the more distinctive symptoms appear. For example, fatigue, thirst, and restlessness may form part of the prodrome of a fever. The word is principally used in medical and epidemiological writing, where precision about the order in which symptoms occur can be important. In less technical contexts, a prodrome may also mean an early sign that a larger event is approaching. This figurative use applies to social, economic, or historical developments, although it remains relatively uncommon. The word is valuable because it distinguishes a warning phase from the full condition itself and from the eventual outcome.

Where does prodrome come from?
The word comes through Latin from Greek prodromos, meaning “forerunner” or “one who runs ahead.” It was formed from pro-, meaning “before” or “forward,” and dromos, meaning “running” or “course.” The English noun developed in medical usage for symptoms preceding the main manifestation of an illness.
