Intro to Health Science

Infection Control and Bioterrorism

microorganism
Microorganism
  • Small living organism
  • Found everywhere, including the human body
  • Many are normal to have
    • Nonpathogens
  • Some cause disease/infection
    • Pathogens/germs
microorganism1
Microorganism
  • Some nonpathogens can become pathogens if they spread to other parts of the body
    • E. coli is in your large intestine but if it enters the urinary system is causes infection
factors required for growth
Factors required for growth
  • Warm environment
  • Darkness
    • Many are killed quickly by sunlight
  • Source of food and moisture
  • Need for oxygen varies
    • Aerobic need it
    • Anaerobic do not
think about it
Think about it…
  • The human body is ideal for all of the conditions… YUCK!
antibiotics
Antibiotics
  • Kill bacteria
  • Some strains are resistant
    • MRSA
viral diseases healthcare workers should be cautious of
Viral diseases healthcare workers should be cautious of:
  • Hepatitis B
    • Transmitted by blood and body secretions
    • Affects liver
    • Vaccine available
    • Healthcare workers MUST get it for free from employer
viral diseases healthcare workers should be cautious of1
Viral diseases healthcare workers should be cautious of:
  • Hepatitis C
    • Transmitted by blood and body secretions
    • Cause serious liver damage
    • Not vaccine
    • Can remain active for several days in dried blood
viral diseases healthcare workers should be cautious of2
Viral diseases healthcare workers should be cautious of:
  • Acquired immunodeficiency syndrome (AIDS)
    • Caused by human immunodeficiency virus (HIV)
    • Suppresses immune system
    • No cure and no vaccine
    • PREVENTION IS KEY!!!
diseases and infections
Diseases and Infections
  • Endogenous
    • Infection/disease originates in the body
  • Exogenous
    • Infection/disease originates outside the body
  • Nosocomial
    • Acquired in a healthcare facility
  • Opportunistic
    • Occur when immune system is suppressed
levels of aseptic control
Levels of aseptic control
  • Antisepsis: prevent/inhibit growth of pathogenic organisms but not effective against spores and viruses
  • Disinfection: kills pathogenic organisms and some spores and viruses
  • Sterilization: destroys all microorganisms
bioterrorism
Bioterrorism
  • Use of microorganisms as weapons to infect humans, animals, or plants
    • 1346: Tartar army threw bodies of dead plague victims over walls of Caffa and caused an epidemic
    • 1763: British army gave Native Americans blankets and handkerchiefs infected with smallpox
    • Germans used it in WWI
    • Japanese did experiments on POW in WWII
    • US, Canada, SU, and GB developed plans of attack in 1960’s
    • Release of sarin gas in Tokyo in 1995
    • Anthrax mail attack in US 2001
