Which term describes transmission via contact with a contaminated surface or object?

• A. Direct
• B. Indirect
• C. Droplet
• D. Vehicle

Answer: (B)

Indirect transmission occurs when a pathogen is spread by touching a surface or object that has been contaminated, and then transferring the organism to oneself or to mucous membranes. This is the situation described by contact with a contaminated surface or object, known as fomite transmission. Direct transmission would be person-to-person contact, not via a surface. Droplet transmission involves respiratory droplets expelled by an infected person and reaching another person within close range. Vehicle transmission refers to contaminated substances like food or water acting as the medium for infection. In phlebotomy practice, recognizing this route highlights the importance of cleaning surfaces and equipment and performing hand hygiene to prevent infection from contaminated objects.
