ANS: C
Infectious diseases are the result of interaction among the human host, an infectious agent, and the environment, which surrounds the human host and where transmission is occurring. This interaction is pictured in the epidemiological triad of agent, host, and environment also discussed in Chapter 5. The antibiotic therapy eliminated a specific pathological agent, but it also may alter the balance of normally occurring organisms in the woman's body, which caused a change in the vaginal environment, allowing normally present fungi to proliferate, resulting in a yeast infection.
Answer to Question 2
ANS: D

There is concern that deadly pathogens will be weaponized by terrorists.
