Which transmission involves contact with an intermediate object such as a razor?

• A. Direct Transmission
• B. Indirect Transmission
• C. Vehicle Transmission
• D. Airborne Transmission

Answer: (B)

The idea being tested is how an infectious agent can move from one person to another via an object that carries it. This is indirect transmission, also called fomite transmission. A razor can become contaminated with microbes and then transfer them to someone else when used by a different person. Direct transmission would require immediate person-to-person contact, such as touching or kissing, without an intermediate object. Vehicle transmission involves contaminated consumables or items that are ingested or injected, like water, food, or needles. Airborne transmission happens when infectious particles travel through the air over distances. So the razor as a separate object between people fits indirect transmission best. To prevent this, use single-use or properly sterilized instruments and practice good hand hygiene.
