Study Notes
Infection-Related Concepts
- The defining characteristic of acute infections is a rapid onset and short duration.
Healthcare-Associated Infections
- Infections associated with the delivery of health care services in a healthcare setting are termed healthcare-associated infections (HAIs).
Chain of Infection
- A common source of reservoir for the etiologic agent in the chain of infection is the infected patient.
- Indirect vehicle-borne transmission occurs when an inanimate object contaminated with an infectious agent is introduced into a susceptible host.
Droplet Transmission
- Droplet spread occurs when droplets containing infectious agents are propelled a short distance through the air, usually during coughing, sneezing, or talking.
Sepsis
- Sepsis is defined as a systemic inflammatory response syndrome (SIRS) caused by a confirmed infectious agent.
Colonization
- The process by which strains of microorganisms become resident flora is called colonization.
Surgical Asepsis
- The primary purpose of surgical asepsis or sterile technique is to reduce the number of microorganisms on the skin and on medical equipment to minimal levels.
Communicable Diseases
- The main characteristic of a communicable disease is that it can be transmitted from one person to another.
Sterility
- Asepsis refers to the absence of almost all microorganisms.
