Question

Which is an example of a reservoir when discussing the chain of infection?

Answers

  1. A client.
    • Rationale:

      One example of a reservoir, or the environment where a pathogen can grow, live, and reproduce, is the human body; therefore, a client is an example of a reservoir in the chain of infection.

  2. Airborne route.
    • Rationale:

      The airborne route is an example of a mode of transmission, not a reservoir, in the chain of infection.

  3. Contact with water.
    • Rationale:

      Contact with water is an example of a route of transmission, not a reservoir, in the chain of infection.

  4. Blood or bodily fluid.
    • Rationale:

      Blood and bodily fluids are a route of transmission, not a reservoir, in the chain of infection.

Overview

The chain of infection is made up of six different links: a pathogen (i.e., infectious agent); reservoir; portal of exit; means of transmission; portal of entry, and the new host.

Explanation

Learning Outcomes

Each link in the chain of infection has a unique role in producing symptoms of infection caused by various pathogens. One link in the chain of infection is the reservoir. It is defined as the environment where the pathogen grows, lives, and reproduces. Reservoirs can include animals, humans (e.g., a client), insects, soil, and water.
