Answer to Question 1

Ans: A, B, D, E
Feedback:
There are several host factors that determine whether a person is at risk for an infection or an infectious disease. These include age, sex, race, physical and emotional health, and immune status. Occupation is not a host factor.

Answer to Question 2

Ans: C
Feedback:
The time between exposure to an infectious agent and the manifestation of symptoms in the host is called the incubation period. Asymptomatic people are carriers of a virus and can transmit the virus to others through percutaneous inoculation, exposure to mucous membranes, and sexual contact. When an infectious agent is present and there are no clinical signs of disease, colonization with the infectious agent is said to have occurred, and the infected person is capable of transmitting the agent. The latent period is the stage of a disease during which symptoms are hidden.
