What is the duration of acute diarrhea?

• A. 1-2 days
• B. 7-14 days
• C. Less than 7 days
• D. 1-3 months

Answer: (C)

Acute diarrhea is defined by a short, self-limited course. In many infectious disease exam contexts, it is classified as lasting less than seven days. That’s why the best choice is the one describing a duration of less than a week. If symptoms persist longer—typically 14–28 days—that’s considered persistent, and beyond four weeks would be chronic, requiring a different evaluation. Most uncomplicated viral gastroenteritis, which often causes acute diarrhea, resolves within a few days, supporting the less-than-seven-day boundary.
