Endogenous Infections
Infection or disease that originates within the body. For example, metabolic disorders, congenital abnormalities, tumors, and infections cause by microorganisms.
Exogenous Infections
Infection or disease that originates outside of the body. For example, pathogenic organism that invade the body, radiation, chemical agents, trauma, electric shock, and temperature extremes. hospital acquired infections are exogenous.
Exogenous Infections
Pathogenic organism that invade the body, radiation, chemical agents, trauma, electric shock, and temperature extremes are said to be?
Endogenous Infections
Metabolic disorders, congenital abnormalities, tumors, and infections cause by microorganisms are said to be?
Nosocomial Infections
Infection that is acquired by a individual in a health care facility such as a hospital or long-term care facility. Transmitted from health care worker to patient.
Opportunistic Infections
Infection that occur when the body's defense are weak. For example the development of Kaposi's sarcoma, Pneumocystis carinii pneumonia in individuals with AIDS.
Endogenous Infections, Exogenous Infections, Nosocomial Infections, Opportunistic Infections
What are the types of infections?
Causative agent
First step in the chain of infection. A pathogen, such as a bacterium or virus that can cause a disease.
Reservoir
Second step in the chain of infection. An area where the causative agent can live. For example, the human, animals, the environment, and fomites.
Fomites
A type of reservoir. An object that is contaminated with infectious material that contain the pathogens.
Portal of exit
Third step in the chain of infection. A way for the causative agent to escape from the reservoir in which it has been growing.
Mode of transmission
Fourth step in the chain of infection. A way that the causative agent can be transmitted to another reservoir or host where it can live.
Direct Contact
Physical contact, sexual contact, or body secretion containing the pathogen. Contaminated hands are one of the most common sources of ____
Mode of transmission
Direct contact is one way a pathogen can be transmitted. Thus making it apart of which chain of infection?
Indirect Contact
When pathogen is transmitted via food, air, soil, insects, feces, clothing, instruments, and equipment.
Portal of entry
Fifth step in the chain of infection. A way for the causative agent to enter a new reservoir or host. For example, Breaks in the skin, mucous membrane, or the respiratory tract.
Mucous Membrane
Lines the respiratory, digestive, and reproductive tracts and traps pathogens.
Cilia
Tiny, hairlike structures that line the respiratory tract and propels pathogens out of the body.
Susceptible host
Sixth step in the chain of infection. A person likely to get an infection or disease, usually because body defenses are weak.
Types of precautions
Standard precautions: precautions to protect you from the patients, body fluids, blood. needle safety.
Transmission based precautions are:
Contact - C. Diff, RSV, norovirus
Airborne-chicken pox, measles, active TB - negative pressure room.
Droplet- flu, pertussis, mumps
