Which term is defined as a disease caused by pathogenic organisms that can be spread from person to person?

• A. Immunity
• B. Infectious disease
• C. Direct contact
• D. Reservoir

Answer: (B)

Diseases caused by pathogenic organisms that can spread from person to person are infectious diseases. Pathogens such as bacteria, viruses, fungi, or parasites are the agents that cause these illnesses, and their defining feature is transmissibility between people through various routes like direct contact, droplets, or contaminated surfaces. This distinguishes infectious diseases from conditions that aren’t contagious. Immunity refers to protection from infection, not the disease itself. Direct contact is a mode of transmission, not the disease name. A reservoir is where pathogens reside or persist, not the disease. So, the term that fits the definition is infectious disease.
