Definition should include the following and describe how to break the chain of infection:

Infectious agent—any microorganism that can cause a disease (e.g., bacteria, virus, parasite, fungus)
Reservoir—where the organism lives, thrives, and reproduces
Portal of exit—where the organism leaves the reservoir (e.g., respiratory tract, intestinal tract)
Mode of transmission—the means by which an organism moves from one host to another
Portal of entry—the opening where an infection enters the host’s body
Susceptible host—a person who is at risk of infection

Process/Skill Questions:

Whose role is it to break the chain of infection?
What methods would be used to break the chain of infection?
What patient populations are most at risk for infection?
What personal protective equipment (PPE) should one wear to break the chain of infection?
What are vectors and fomites?
