Infection Control Flashcards
Direct Contact
Lesions, saliva, blood, fluids
Indirect Contact
Contaminated items w patients mo’s- surfaces, hands, sharps
Droplet Infection
[splatter] large particle droplet (50ùg+) mo’s directly into body vi skin, membranes, eyes, nose,mouth
Airborne infection
Small particles (<50ùg) can be INHALED
Major source of disease in dental office:
Patients mouth!
OPIM
[other potentially infectious materials]
semen, vaginal secretions, saliva, cerebrospinal fluid
Chain of Disease Transmission
Infectious Agent > Reservoirs > Port of exit > Transmission > Port of entry > Susceptible host
Infectious Agent
Bacteria, fungi, virus, Protozoa, rickettsiae
Reservoirs
People, equipment, instruments, water (tubing)
Port of Exit
Secretions: saliva, blood
Skin and mucus membranes
Droplets
Transmission
Direct contact, indirect contact (finite/vector), airborne
Port of Entry
Mucus membrane, GI tract, respiratory tract, broken skin, eyes
Susceptible Host
Immunocompromised, elderly, medically compromised
Sterilization
Destruction of ALL microbial forms
Disinfection
Inhibition of some pathogenic organisms (excluding spirea) INANIMATE OBJECTS
Antiseptic
Inhibition of some pathogenic organisms (excluding spores) on LIVING TISSUE
