Indirect transmission is best described as which of the following?

• A. Touch Or Needle Stick
• B. Contaminated Objects
• C. Airborne Droplets
• D. Vector-Borne Transmission

Answer: (B)

Indirect transmission means the pathogen moves through an intermediary rather than from one person to another directly. In healthcare, the classic route is via inanimate objects that become contaminated and then pass the pathogen to a new person—fomite transmission. That’s why contaminated objects best describe indirect transmission: the infection is picked up from an object rather than through direct contact or through the air.

Touching or needle-stick injuries involve direct transfer from one person to another (or to the worker), so they’re direct transmission rather than indirect. Airborne droplets describe transmission through the air when droplets are expelled and inhaled, which is also a direct form of spread between people in proximity. Vector-borne transmission uses a living carrier, like an insect, to move the pathogen, which is a different indirect pathway involving a biological vector.
