host --> transmission
source - Correct Ans-infectious agent or germ and refers to a virus, bacteria, or other
microbe. (germs) live (ex. sinks, surfaces, human skin"
transmission - Correct Ans-a way germs are moved to the susceptible person
who are a source of germs? - Correct Ans-patients, healthcare workers,
visitors/household members
examples of environmental sources of germs - Correct Ans-Dry surfaces in patient care
areas (ex. Bed rails, medical equipment, countertops, tables)
Wet surfaces, moist environments, biofilms (ex. Cooling towels, faucets, sinks,
ventilators)
Indwelling medical devices (catheters, IV lines)
Dust or decaying debris (construction dust or wet materials from water leaks)
who is susceotible? - Correct Ans-someone who is not vaccinated or otherwise immune,
or a person with weakened immune system who has a way for the germs to enter the
body (IV's, catheters, surgical incisions all provide an entry way)
patients with underlying conditions
certain medications to treat conditions (steroids, antibiotics)
lifesaving medical procedures used in healthcare such as catheters, tubes, and surgery
increase risk of infection by providing additional entryways
transmission of germs .. - Correct Ans-germs dont move themselves; they depend on
people, the environment, and equipment/surfaces
examples of how germs are moved - Correct Ans-touch; (healthcare provider hands

surfaces and then carry the germs on their hands and spread to a susceptible person
when proper hand hygiene is not performed before touching the susceptible person)
, sprays and splashes; (occur when an infected person coughs or sneezes, creating
droplets which carry germs short distances (within approximately 6 feet). These germs
can land on a susceptible person's eyes, nose, or mouth and can cause infection
(example: pertussis or meningitis)
inhalation; (occurs when germs are aerosolized in tiny particles that survive on air
currents over great distances and time and reach a susceptible person. Airborne
transmission can occur when infected patients cough, talk, or sneeze germs into the air
(example: TB or measles), or when germs are aerosolized by medical equipment or by
dust from a construction zone (example: Nontuberculous mycobacteria or aspergillus).
sharp injuries; (can lead to infections (example: HIV, HBV, HCV) when bloodborne
pathogens enter a person through a skin puncture by a used needle or sharp
instrument.)
