- Examples: education, adequate treatment to arrest disease process and prevent further complications.
- Has the disease or sickness, disability
- Examples: doing whats possible to correct the problem or try to make it less. (highest level of functioning is goal)
- Usually short term and severe.
- Examples: surgery
- usually lasts longer than 6 months. Patients fluctuate between maximal functioning and serious health relapses that are sometimes life threatening.
- Example: Diabetic
The presence and growth of microorganisms within ahost but without tissue invasion or damage.
- infection disease transmitted directly from one person to another.
- Examples: T.B.
- pathogens multiply and cause clinical signs and symptoms
- clinical signs and symptoms are not pressent.
- (No Signs)
Chain of Infection
- Portal of entry
- Host susceptibility
- infectious agent
- Portal of exit
Modes of Transmission
- There are 4 kinds of modes:
Contact (Modes of Transmission)
- Direct: Person to person or physical contact between source and susceptible host.
- Indirect: Personal contact of susceptible host with contaminated inanimate objects
- Droplet: Large particles that travel up to 3 feet and come in contact with susceptible host.
Airborne (Modes of Transmission)
- Droplet nuclei, residue or evaporated droplets suspended in air.
- example from coughing, sneezing, talking
Vehicles (Modes of Transmission)
- Contaminated items
- drugs, solutions
Vector (Modes of Transmission)
- External mechanical transfers (flies)
- Internal transmission such as with parasitic conditions between vecotr and host.
- examples: Mosquito, Louse, tick, Flea
- The over use of antibiotics.
- can destroy normal flora.
health care-acquired infection
A person gets a disease due to the care provider.
an effort to keep the patient as free from exposure to infection causing pathogens as possible.
means the absence of disease producing micoorganisms.
Medical Asepsis (one of two type of asepsis)
- clean techniques, includes procedures used to reduce the number of and prevent the spread of microorganisms.
- Example: Hand Hygiene, Barrier techniques, and routine environmental cleaning.
Surgical Asepsis (one of two type of asepsis)
- Sterile technique, includes procedures to eliminate all microorganisms from an area.
- Examples: Sterilization destroys all microorganisms and their spores.
