Which statement accurately describes passive/indirect transmission?

Which statement accurately describes passive/indirect transmission?

• A. It requires the organism to replicate within the source
• B. It occurs when an organism is present but does not replicate within the source
• C. It only applies to hep A
• D. It is the same as direct contact transmission

Answer: (B)

Passive or indirect transmission means pathogens move from a source to a susceptible host via an intermediary, such as hands, clothing, or inanimate objects, without the organism needing to replicate in that source. The statement that best captures this is that the organism is present but does not replicate within the source. In real-world terms, a germ might hitch a ride on a contaminated surface or a caregiver’s gloves and be transferred to another person without multiplying in the surface or on the glove. This distinction is why indirect transmission differs from direct contact, which involves immediate transfer from one person to another, and why it’s not limited to a single pathogen like Hep A.
