Which statement is most accurate about direct transmission?

• A. It requires contact with another person.
• B. It never requires contact with another person.
• C. It always involves a vector.
• D. It only occurs in healthcare settings.

Answer: (A)

Direct transmission is the spread of infection from one person to another through close contact or exchange of bodily fluids. Because the transfer happens through direct interaction, it requires contact with another person rather than occurring from a distance or via a middle actor. This includes touching someone who is infected, sharing secretions, or droplets that reach a person’s mucous membranes during close contact. It does not involve a vector, and it can happen anywhere, not just in healthcare settings.
