Which term refers to a disease that spreads quickly from person to person?

• A. Contagious disease
• B. Communicable disease
• C. Bloodborne pathogens
• D. Cocci

Answer: (A)

Spreading quickly from person to person is described by contagious, because contagion refers to rapid transfer of infection through direct contact, droplets, or close proximity. A contagious disease implies it's easily and readily transmitted between people. Communicable means capable of being transmitted, but it’s a broader term and doesn’t necessarily emphasize speed or ease of spread. Bloodborne pathogens are transmitted through blood exposure, not specifically about rapid person-to-person spread, and cocci is just a bacterial shape, not a disease category. So the best fit is contagious disease.
