Unit 3.1 Flashcards - Chain of Infection

Chain of Infection

Key Concepts

• Chain of Infection: A process with steps that describes how infectious agents spread. It's crucial to carefully review each step.
• Susceptible Host: An individual who is at risk of infection.
• Reservoir: A place where infectious agents live and multiply.

Discussion Points

• Sources of Infectious Agents: Consider possible origins and locations where infectious agents can be found.
• Transmission: Discuss how infectious agents spread from one host to another (direct vs. indirect).

Transmission Types

• Direct Contact: Transmission of infectious agents occurs through physical contact.
• Indirect Contact: Transmission occurs through an intermediate object or vector.

Susceptibility

• Factors Affecting Susceptibility: Discuss what makes a host more or less susceptible to infectious diseases.
• Hospital Patients: Hospital patients might be more susceptible to disease given their conditions and presence in a hospital environment; this should be explained further.

Steps

• Step #1: Carefully review the chain of infection.
• Step #2: Draw the chain of infection.

Questions for Consideration

• Transmission Type: Determine whether a specific transmission is direct or indirect.
• Host Susceptibility: Analyze factors influencing a host's susceptibility to infectious disease.
