Which term defines a disease that can be transmitted from one person to another?

• A. Contagious infection
• B. Bloodborne pathogens
• C. Local infection
• D. General infection

Answer: (A)

Contagious infection describes a disease that can be passed from one person to another. Contagious means able to be spread through direct contact, droplets, or contaminated surfaces, which is exactly what the question is asking about. The other terms point to different ideas: bloodborne pathogens are specific agents transmitted through blood (not every contagious disease is primarily bloodborne), a local infection is confined to one area of the body, and a general infection is systemic but doesn’t inherently specify how easily it spreads between people. So the term that best matches a disease that can be transmitted from person to person is contagious infection.
