Answer to Question 1

ANS: C
Indirect transmission is the spread of infection through a vehicle of transmission outside the host. These may be contaminated fomites or vectors. Fomites can be any inanimate object, material, or substance that acts as a transport agent for a microbe (e.g., water, a telephone, or a contaminated tissue).

Answer to Question 2

ANS: D
The principle of multicausation emphasizes that an infectious agent alone is not sufficient to cause disease; the agent must be transmitted within a conducive environment to a susceptible host. Mycobacterium tuberculosis kills cells. M. tuberculosis has low infectivity, low pathogenicity, but high virulence if untreated.
