Infection Control

Principles of Disease


  • Small living plant or animal
  • Non-pathogens
    • Live in or on the body
    • Part of the normal flora
    • May be beneficial to the body
  • Pathogens
    • Germs
    • Cause infection
types of pathogens
Types of Pathogens
  • Bacteria
    • One celled plants
    • Classified by shape and arrangement
    • Cocci – strep, staph
    • Bacilli – TB, tetanus
    • Spirilla – syphilis, cholera
    • One celled animals
    • Found in decayed material and contaminated water
    • Malaria, dysentery
    • Simple plant-like organism
    • Live on dead matter
    • Yeasts, molds
    • Ringworm,athlete’s foot, thrush

- Parasitic microorganism

  • Transmitted to humans through the bite of a tick,fleas, Typhus and lice, mites
  • Rocky Mountain spotted fever
    • Smallest microorganism
    • Can only reproduce inside humans cells
    • Colds, chicken pox, warts, influenza, HIV, Hepatitis
needs of microorganisms
To Grow



Source of food


Aerobic need oxygen

Anaerobic – don’t need oxygen

Needs of microorganisms
how pathogens cause infections
How Pathogens Cause Infections
  • Poisons/toxins
    • Ex: tetanus
  • Allergic Reactions
    • Ex: runny nose, sneezing
  • Attack and Destroy cells they invade
    • Ex: malaria
additional classifications
Additional Classifications
  • Endogenous
    • Originates inside the body
  • Exogenous
    • Originates outside the body
  • Nonsocomial
    • An infection acquired inside the hospital
  • Opportunistic
    • Infections that occur when the body’s immune system is weak
  • Absence of disease-producing microorganisms
  • Any area or object containing pathogens is considered contaminated
levels of aseptic control
Levels of aseptic Control
  • Antisepsis
    • Prevent or inhibit the growth of pathogenic organism but are not effective against spores or viruses.
    • Ex: Alcohol/Betadine
  • Destroys or kills pathogenic organisms but not always effective against spores or viruses
  • Ex: Bleach, Clorox
  • The process that destroys all microorganisms both pathogenic and non-pathogenic including spores and viruses.
  • Ex: Steam under pressure, autoclave, gas, radiation, chemicals
two main ways pathogens spread
Two Main Ways Pathogens Spread
  • Blood
    • HIV
    • Hepatitis B
    • Hepatitis C
  • Body Fluids
  • Occupational Safety and Health Administration
  • 1991 established

blood-borne pathogen

standard regulations

  • Determine employees who have occupational exposure
  • Provide the Hepatitis B vaccine free
  • Provide PPE – Personal Protective Equipment
  • Provide adequate hand washing facilities
  • Ensure the worksite is maintained in a clean and sanitary condition
regulations cont
Regulations Cont.
  • Enforce NO eating , drinking, smoking, applying lip balm or lipstick, handling contact lenses or mouth pipetting in any area potentially contaminated with blood or body fluids.
  • Provide adequate sharps containers coded red/orange
  • Post signs in areas where there is occupational exposure
Provide confidential medical evaluation and follow up for any employee with an exposure
  • Provide free training for any new updates or changes
  • all needles
  • syringes
  • syringe bodies
  • scalpels
  • lancets
  • any glass items, such as slides or Pasteur pipettes, that are contaminated with potentially infectious material and/or human blood.
  • Personal



sterile technique
Sterile Technique
  • Sterile
    • Free from all organisms
  • Contaminated
    • Organisms and pathogens are present
    • Items that touch your clothes or skin or any area below the waist are considered contaminated
sterile field
Sterile Field
  • Never reach across the top of the field
  • Reach in from the sides to add to the field
  • Never turn your back to a sterile field
  • 2 inches around the border are contaminated
  • Anything below the level of the tray is contaminated
methods to remove sterile articles from sterile wraps
Methods to Remove Sterile Articles from Sterile Wraps
  • Drop Method
  • Mitten Method
  • Transfer Forceps
sterile field30
Sterile Field
  • Keep Sterile field dry
  • Pathogens move quickly through wet surfaces
  • Take care when pouring solutions into a sterile field
  • When you put on sterile gloves, only handle sterile items
standards precaustions
Standards Precaustions
  • Used when contacting all patients
transmission based isolation
Transmission-based Isolation
  • Airborne
  • Droplet
  • Contact
  • Protective
communicable diseases
Communicable Diseases
  • A disease caused by a pathogic organism that can be easily transmitted to others
  • Spread by
    • Direct contact with patient
    • Contact with blood and body fluids
    • Droplets
    • Discharge from wounds
