Define the key terms on your Infection Control SLM  biohazard = biohazardous  BBP = Blood-borne pathogen: a pathogen present in blood that can be transmitted to an individual who is exposed to the blood or body fluids of an infected individual.  HIV (see p. 184)  AIDS (see p. 184)  Add to your list: Personal protective equipment (PPE) (see p. 306)

Copy the table & fill it in using pgs of the red book PathogenWhat is itExamples Bacteria Protozoa Fungi Rickettsiae Viruses

Types of infections (use pgs. 301 to define)  Endogenous  Exogenous  Nosocomial ( a.k.a. Hospital Acquired Infection, HAI)  Opportunistic

Other terms for infections  Local infection – in a body part  Systemic infection – involved the whole body  Communicable – can be transmitted from one person to another  Multi-drug resistant organisms (MDRO) – organisms that can resist the effects of antibiotics  Examples: MRSA (Methicillin Resistant Staphylococcus) VRE (Vancomycin resistant Enterococcus)

Using pgs  List out the components in the chain of infection  Provide a brief description of each

Think about it…  Which links in the chain of infection do you think are easiest to break? Why?

Modes of Transmission  Airborne  Bloodborne  Vectorborne – a vector (such as lice, ticks, or mosquitoes) becomes infected and then infects the host; may be called indirect transmission  Sexual  Foodborne  Casual Contact

Measles  Measles is a highly contagious virus that lives in the nose and throat mucus of an infected person. It can spread to others through coughing and sneezing. Also, measles virus can live for up to two hours in an airspace where the infected person coughed or sneezed. If other people breathe the contaminated air or touch the infected surface, then touch their eyes, noses, or mouths, they can become infected. Measles is so contagious that if one person has it, 90% of the people close to that person who are not immune will also become infected.  department-of-health-confirms-measles-case department-of-health-confirms-measles-case

Asepsis = being free of disease- producing microbes  Levels of aseptic control  Antispesis: prevent growth of organisms; not effective against spores (fungi) & viruses; examples = alcohol & betadine  Disinfection: destroys / kills pathogens; not always effective against spores & viruses; example = bleach; commonly used on objects, not people

Asepsis cont  Sterilization = kills / destroys all microorganisms; usually done by autoclave (machine that uses steam & high pressure); can NOT be used on people; usually used on instruments / tools  Contamination = process of becoming unclean

Supplies & equipment  Many pieces of equipment are disposable, however, non-disposable items must be cleaned & disinfected  Disinfection = process of destroying pathogens  Germicides = disinfectants applied to skin, tissues, and non-living objects  Chemical disinfectants – used to clean surfaces and reusable items

On your paper, answer in complete sentences… 1.What is the responsibility of OSHA? 2.What is infection control and how would you break the chain of infection?
