Answer to Question 1

Ans: C
Feedback:
A propagated outbreak is one where the infection is transmitted from person to person over a longer period of time than with a common source outbreak, and it can generate secondary infections with intervals between peaks that approximate the usual incubation period for the infection. A common source outbreak is one that has the same origin. Secondary infections are those that occur within the accepted incubation period following exposure to a primary case.

Answer to Question 2

Ans: A
Feedback:
An endemic disease, infection, or infectious agent occurs when it becomes prevalent within a population or geographic area. An epidemic or outbreak refers to a significant increase in an infection or infectious disease beyond the expected (endemic) level in a certain population and/or geographic area. A pandemic is an epidemic that generally spreads worldwide. The use of outbreak in this text is synonymous with epidemic.
