Which term describes a disease in which peak severity of symptoms occurs and subsides within three months?

• A. Chronic
• B. Infectivity
• C. Rates/Proportion
• D. Acute

Answer: (D)

Understanding disease duration terms is the key here. An acute illness is one that starts suddenly and runs a short course, with symptoms that reach a peak and then subside within a relatively brief period. Saying the peak and recovery occur within about three months fits this rapid, self-limited pattern. In contrast, chronic describes long-lasting or lifelong illness; infectivity is about how easily the disease spreads, and rates/proportion are population-level measures, not descriptions of how long an illness lasts. So the term that best matches a disease whose peak severity resolves within three months is acute.
