Which term is described as the host (or patient)?

• A. Host
• B. Pathogen
• C. Reservoirs
• D. Sender

Answer: (C)

The key idea is identifying what serves as the source that harbors the infectious agent. A reservoir is the organism or environment in which a pathogen normally lives, grows, and multiplies, and it can be the source from which transmission occurs. When a patient hosts a pathogen, they can act as a reservoir, sustaining the infection and potentially passing it to others. The pathogen is the disease-causing agent, not the host, and terms like sender aren’t standard labels in this basic framework.
