An epidemic curve showing a sharp rise and a rapid decline, with cases clustered around a single exposure event, is characteristic of which type of epidemic?

Explanation

A common source, point exposure epidemic occurs when a group of people are exposed to the same source over a relatively brief period. This results in a sharp, rapid increase in cases followed by a rapid decline, with the cases typically occurring within one incubation period of the disease. Propagated epidemics show successive waves of cases, while continuous common source epidemics show a plateau.
