Infection Control Nature of infection
● Infection
● Colonization
● Infection disease
Hospital Acquired Infections Can develop during a client's stay or manifest after
(Nosocomial infections): discharge (48 hours).
TOP THREE HAI:
● MRSA
● UTI most common ( frequent cause of gram
negative septicemia)
● Surgical site infection
● Pneumonia
-Clostridium difficile (C.DIFF) result of antibiotic
therapy
-Prevalent in hospital surgical and medical ICU
Endogenous: microorganism comes from the client
themselves. An endogenous infection is a disease
arising from an infectious agent already present in
the body but previously asymptomatic.
Endo- "within" genous "born from"
Exogenous: microorganism from the hospital or hospital
personnel
● Iatrogenic infection: direct result of
diagnostic/ therapeutic procedure
● Prevention:
i. Handwashing
ii. Immunizations
iii. Prevent airborne droplets from
spreading
iv. Precautions when handling
, potentially contaminated materials
Exo- "outside"; -genous "born from"
HAI Occurs as the results of: (Could be life
threatening).
● Invasive procedures
● Antibiotic administration
● Multidrug resistant organism (MDROs)
● Breaks in infection prevention and control
activities
Chain of Infection 1. Infection agent
2. Reservoir
3. Portal of exit
4. Mode of transmission
5. Portal of entry
6. Host
The Infectious process Defenses against Infection
● Normal Floras
, ● Body systems defenses
● Inflammation:
1. Vascular and cellular responses
2. Inflammatory exudate
3. Tissue repair
5 Stages of Infection Incubation, prodromal, illness, decline, convalescence.
Incubation: The incubation stage includes the time
from exposure to an infectious agent until the onset of
symptoms.
Prodromal: The prodromal stage refers to the period
after incubation and before the characteristic
symptoms of infection occur.
Illness: The third stage of infection is an illness or
clinical disease. This stage includes the time when a
person shows apparent symptoms of an infectious
disease.
Decline: During the decline stage, the immune system
mounts a successful defense against the pathogens,
and the number of infectious particles
decreases.Symptoms will gradually Improve. However, a
person can develop secondary infections during this
stage if the primary infection has weakened their
immune system.During this stage, the virus can still
transmit to other people.
Convalescence: The final stage of infection is known as
convalescence. tissue repair, return to health
Factors influencing infection prevention ● Age
and control: ● Sex
● Nutritional status
● Stress
● Distress
● Disease process
Hand Hygiene (know gel rub, routine hand Three essential components of handwashing
