Infection Control: Chain of Infection

When certain conditions occur and disease spreads from one person to another it is called:

• Infection Control

• Chain of Infection

• Chain of Disease

• Infection Pathway

A pathogen that can cause disease is a:

• Macroorganism

• Infectious Agent

• Reservoir

• Susceptible Host

The place infectious agents can live, including the human body, animals and the environment

• Infectious agent

• Reservior

• Portal of Exit

• Portal of Entry

A way for the infectious agent to escape from the reservoir in which it has been growing

• Infectious Agent

• Reservior

• Portal of Entry

• Portal of Exit

The way the infectious agent can be transmitted to another reservoir or host where it can live:

• Portal of Exit

• Mode of Transmission

• Portal of Entry

• Susceptible Host

Person-to-person contact (physical or sexual contact) or contact with a body secretion containing pathogens

• Indirect Contact

• Direct Contact

• Non-Contact

Pathogens are transmitted from contaminated substances or objects such as food, air, soil

• Indirect Contact

• Direct Contact

• Non-contact

The way for the infectious agent to enter a new reservoir or host

• Mode of Transmission

• Portal of Exit

• Portal of Entry

• Susceptible Host

A person likely to get an infection or disease, usually because the body defenses are weak

• Reservior

• Mode of Transmission

• Portal of Entry

• Susceptible Host

The absence of disease-producing microorganism or pathogens

• Asepsis

• Sterile

• Contaminated

• Disinfection
