Infection Control Flashcards
OSHA
occupational safety and health administration
OSHA is a US government agency under the
department of labor
what is OSHAs mission
to ensure safety in the workplace
1986 OSHA began to develop
the new blood borne pathogens standards
in 1991,
mandatory blood borne pathogen standards were made
CDC
center for disease control and prevention
CDC is the – — — agency
US public health
what does the CDC review
current scientific information
CDC creates
recommendations
what trends does the CDC track?
disease trends across the country
what does the CDC serve as a primary investigator for?
when disease outbreak threatens public health
infection prevention and control refers to the policies and procedures used to
minimize the risk of spreading infections in the healthcare setting
chain of infection
process by which infectious diseases are transmitted
three opponents of a chain of infection
a causative agent
a susceptible host
a mode of transmission
all three components are necessary for infection to spread. infection control strategies are intended to break one or more of the links, thereby preventing disease transmission
causative agent
any microorganism in sufficient numbers capable of causing disease (pathogen)
causative agents can include a variety of (4)
viruses
bacteria
protozoa
fungi
pathogens can be present in
blood or OPIM
blood borne pathogens of concern in dentistry (3)
not typical of a blood borne pathogen (1)
hep B virus: HBV
hep C virus: HCV
human immunodeficiency virus: HIV
Sars CoV 2
susceptible host
a person who lacks the effective resistance to a particular pathogen
factors that influence a persons level of susceptibility (5)
age physical conditions medications immunization underlying medical conditions
mode of transmission
the mechanism by which the pathogen makes its way to the host
types of mode of transmission (3)
direction contact: occurs when a pathogen is transmitted directly from an infected person to you
indirect contact: occurs when an inanimate object serves as a temporary reservoir for the pathogen
airborne: when the pathogen is airborne via droplet spatter or aerosols
three main ways in which covid 19 is spread
breathing in air when close to an infected person who is exhaling small droplets and particles that contain the virus
having these small droplets and particles that contain virus land of the eyes, nose, or mouth, especially through splashes and sprays like a cough
touching eyes, nose, or mouth with hands that have the virus on them
droplet transmission
coughs and sneezes can spread droplets of saliva and mucus
