Which term means easily spread from one person to another?

• A. Communicable
• B. Pathogenic
• C. Saprophyte
• D. Bacilli

Answer: (A)

Spread between people is what this term captures. A communicable disease is one that can be transmitted from one person to another through direct contact, droplets, or contaminated surfaces. That direct link to transmission is why it’s the best fit for “easily spread from one person to another.” Pathogenic just means disease-causing, but it doesn’t specify how or how easily it spreads. Saprophyte refers to organisms that feed on dead matter, not transmission between people. Bacilli describes a rod-shaped form of bacteria, not the ability to spread between individuals. So the idea of being transmissible from person to person points to communicable.
