Indirect transmission can occur via which of the following?

• A. Direct Contact
• B. Vehicle (Fomite)
• C. Droplet Spread
• D. Airborne

Answer: (B)

Indirect transmission happens when a pathogen is passed via an object or substance that has been contaminated, not by touching the infected person itself. A vehicle or fomite is any inanimate item that carries the organism, such as a doorknob, shared equipment, or a towel. If someone touches that contaminated object and then touches their face, the pathogen can enter the body. This is why surface cleaning, disinfection, and diligent hand hygiene are key protections. Droplet spread and airborne transmission involve direct exposure to respiratory emissions or inhaled particles, while direct contact is physical contact with an infected person; neither relies on an inanimate object as the intermediary. So, the best match is indirect transmission via a vehicle (fomite).
