The MOST effective way to control the spread of infection
Warm water -Hands and wrist-Antibacterial soap-At least 10 seconds
Alcohol sanitizer is no substitute for washing

Living organisms too small to be seen with the naked eye.
Includes: bacteria, virus, prions- proteinaceous infectious particle, fungus

Disease causing microorganisms
Types of pathogens would include …..
Viral
Bacterial
Fungal
Other parasites
Prionic

Reducing the probability of infectious organism being transmitted to a susceptible individual
Clean Technique

ie E. coli
single-cell organisms
can grow independently, do not need a host cell to survive.
can adapt to new conditions
able to mutate to survive new environments
(Meningitis, Typhoid fever)

ie AIDS Virus
Among smallest known disease-causing organisms
cannot survive independently
needs host cell to survive and multiply
Antibiotics have no effect on viruses
(Anthrax, Herpes, Mumps, Rabies, Chicken Pox)

ie Athletes Foot
Classified as single-celled yeast or multi-celled mold
Used in beer, bread, cheese, penicillin, decomposition
(Athletes foot, Ringworm, Pneumonia)

healthy individuals that host pathogens without symptoms of the disease
Every healthcare provider is a potential carrier

Mary Mallon (1869 – 1938)
- Irish immigrant (1883)
- first known healthy carrier of Typhoid in the U.S.
- worked as household cook (1900 – 1907)

She contracted mild case of typhoid fever but
was never cured, so she spread the disease
to others.
-22 infected and 1 died

Factors involved in spread of disease: Infectious Organism- Reservoir of Infection - Portal of Exit -
Means of Transmission- Portal of Entry - Susceptible Host
