Infection
-
An infection in a body part.
Local Infection
-
An infection involving the whole body.
A systemic infection.
-
A human or animal that is a reservoir for microbes but does not have signs and symptoms of infection.
Carrier
-
Asepsis
Being free of disease-producing microbes
-
An inflammation and infection of lung tissue.

- pubis: pubic hair
- corporis: body
-
A skin disorder caused by a female mite.
Scabies
-
Medical asepsis (cleann technique) is the practices use to:
- -Remove or destroy pathogens. The number of pathogens is reduced.
- -Prevent pathogens from spreading from one person or place to another person or place.
-
The process of becoming unclean.
Contamination
-
Clean
An item or area is clean whenn it is free of pathogens. The item or area is contaminated if pathogens are present.
-
The absence of all microbes--pathogens and non-pathogens.
Sterile. A sterile item or area is contaminated when pathogens or non-pathogens are present.
-
Signs and Symptoms of Infection
Fever, increased pulse and respiratory rates, pain or tenderness, fatique and loss of energy, loss of appetite (anorexia), nausea, vomiting, diarrhea, rash, sores on mucous membranes, redness and swelling of a body part, discharge or drainage from the infected area.
-
The easiest and most important way to prevent the spread of infection.
Hand hygiene
-
Reduces the number of mirobes present. It also removes organic matter--blood, body fluids, secretions, and excretions.
Cleaning
-
The process of destroying pathogens.
Disinfection
-
The process of destroying all microbes.
Sterilizaton. Very high temperatures are used. Items are sterilized by the manufacturer or the center's supply department.
-
Has quidelines for Standard Precautions and Transmission-Based Precautions.
The Centers for Disease Control and Prevention
-
Standard Precautions and Transmission-Based Precautions
They prevent the spread of communicable or contagious diseases. They are diseases caused by pathogens that are spread easily.
-
Standard Precautions
Reduce the risk of spreading pathogens and known and unknown infections. They prevent the spread of infection from: blood, all body fluids, secreation, and exretions, non-intact skin (skin w/ open breaks), and mucous membranes.
-
Isolation Precautions
They involve wearing gloves, a gown, a mask, or protective eyewear.
-
Masks
A wet or moist mask is contaminated. When removing a mask touch only the ties. When putting on a mask do not touch the part that will cover your face. Tie upper strings first. Put gloves on after putting mask on and remove gloves before removing mask. Untie lower strings first.
-
PPE
Personal Protective Equipment. This includes gloves, goggles, face shields, masks, laboratory coats, gowns, shoe covers, and surgical caps.
-
Most pathogens need the following to grow
Water, oxygen, nourishment, and a warm dark environment. They are destroyed by heat and light.
