An indwelling catheter contaminated during insertion leads to infection. What mode of transmission is this?

Explanation:
Indirect transmission occurs when a contaminated object or instrument transfers pathogens to a person. In this case, the catheter becomes contaminated during insertion and then introduces infection to the patient, so the infection is spread via the contaminated device rather than by direct person-to-person contact. It isn’t spread through the air or by a vector, and it doesn’t require contact with another person, which is why those modes don’t fit here. This illustrates how a contaminated instrument can act as a vehicle for infection during a medical procedure.
