The time between exposure and first signs of disease is called

• A. Incubation period
• B. Prodromal stage
• C. Full stage of illness
• D. Convalescence

Answer: (A)

The time between exposure to a pathogen and the appearance of the first signs is called the incubation period. This interval is when the infection is developing in the body but not yet clinically evident, so the person may feel well while the pathogen multiplies. After incubation, some diseases enter a prodromal stage with early, nonspecific symptoms, followed by the full stage of illness with characteristic signs, and then convalescence, the recovery period. So the incubation period specifically matches the window from exposure to first signs.
