Which statement describes passive/indirect transmission in the context of Hepatitis A in food?

• A. Direct droplet transmission
• B. An organism present and does not replicate within the source, such as hep A in food
• C. Sterilized medical instruments
• D. Airborne transmission

Answer: (B)

Passive/indirect transmission involves a pathogen carried by a vehicle, such as food, water, or a surface, where the agent does not multiply in that source and infection occurs after exposure to the vehicle. In Hepatitis A, the virus can be present in contaminated food without growing there; a person becomes infected when they eat that contaminated food. This is why the description “an organism present and does not replicate within the source, such as hep A in food” best fits passive/indirect transmission. This differs from direct droplet transmission, which involves immediate transfer from an infected person to another person via droplets, and from airborne transmission, which involves small particles traveling through the air. The concept is also not about sterilized medical instruments.
