Module 2: Key Terms Flashcards
Acute Infection
An infection of short duration that is often severe.
Blood-borne Disease
Disease such as HBV, HCV, or HIV infection that is caused by microorganisms such as viruses or bacteria that are carried in blood.
Chain of Infection
Conditions that all must be present for infection to occur.
Chronic Infection
An infection of long duration.
Communicable Disease
Condition caused by an infection that can be spread from person to person or through contact with body fluids.
Direct Contact
Touching or contact with a patient’s blood or saliva.
Droplet Infection
An infection that occurs through mucosal surfaces of the eyes, nose, or mouth.
Immunity
Ability of the body to resist disease.
Indirect Contact
Touching or contact with a contaminated surface or instrument.
Infection Control
Policies and practices designed to prevent the spread of infectious agents.
Latent Infection
Persistent infection with recurrent symptoms that “come and go.”
Occupational Exposure
Any reasonably anticipated skin, eye, or mucous membrane contact or percutaneous injury involving blood or any other potentially infectious materials.
Pathogen
Disease-causing organism
Personal Protective Equipment (PPE)
Items such as protective clothing, masks, gloves, and eyewear used to protect employees.
Standard Precaution
Standard of care designed to protect healthcare providers from pathogens that can be spread by blood or any other body fluid via excretion or secretion; expands upon the concept of
Universal Precautions
Guidelines based on treating all human blood and body fluids (including saliva) as potentially infectious.
Virulence
Strength of a pathogen’s ability to cause disease; also known as pathogenicity.
Antiseptic
Substance for killing microorganisms on the skin.
Bio Burden
Blood, saliva, and other body fluids.
Broad-Spectrum Activity
Capable of killing a wide range of microbes.
Clinical Contact Surface
Surface touched by contaminated hands, instruments, or spatter during dental treatment.
Disinfectant
Chemical used to reduce or lower the numbers of microorganisms on inanimate objects.
Environmental Surface
Surface within a healthcare facility that is not directly involved in patient care, but that may become contaminated during the course of treatment (e.g., countertops, floors, walls, instrument control panels).
Fungicidal
A product that is capable of killing fungi.
Glutaraldehyde
Environmental Protection Agency (EPA)–registered high-level disinfectant.
High-Level Disinfectant
Hospital disinfectant with tuberculocidal activity.
Hospital Disinfectant
Disinfectant with the ability to kill Staphylococcus aureus, Salmonella choleraesuis, and Pseudomonas aeruginosa.
Housekeeping Surfaces
Surface that is not contaminated during dental treatment (e.g., floors, walls).
Immersion Disinfectant
Disinfectant used for immersion (soaking) of heat-sensitive instruments.
Intermediate-Level Disinfectant
Liquid disinfectant with EPA registration as a hospital disinfectant with tuberculocidal activity. It is used for disinfecting operatory surfaces.
Iodophor
EPA-registered, intermediate-level hospital disinfectant.
Low-Level Disinfectant
Disinfectant that destroys certain viruses and fungi; used for general house cleaning (e.g., walls, floors).
