28
 CLostridium
difficile (klos-TRID-e-uhm dif-uhSEEL), often called C. difficile or C. diff, is a
bacterium that can cause symptoms ranging
from diarrhea to life-threatening
inflammation of the colon. Most commonly
affects older adults in hospitals or in long
term care facilities and typically occurs after
use of antibiotic medications.
 May
require isolation of persons affected
29
 Hand
washing: Health care workers should
practice good hand hygiene before and after
treating each person in their care.
 In
the event of a C. difficile outbreak, using soap
and warm water is a better choice for hand
hygiene, as alcohol-based hand sanitizers may not
effectively destroy C. difficile spores. Teach
visitors to practice good hand washing as well.
30
 Staphylococcus
aureus (MRSA) is a
bacterium responsible for several difficultto-treat infections in humans.
 To prevent the spread of staph or MRSA in
the workplace, employers should encourage
proper hand washing and sanitizing of
environmental surfaces and contaminated
equipment with EPA registered disinfectives.
31
 Although
alcohol-based rubs remain somewhat
effective, a more effective strategy is to wash
hands with running water and an anti-microbial
cleanser with persistent killing action.
 Proper
disposal of isolation gowns is also necessary
 MRSA
can survive on surfaces and fabrics, including
privacy curtains or garments worn by care
providers
32
 Hospital
staff and visitors wear disposable
gloves and gowns while in the room
 In
any setting, all surfaces should be carefully
disinfected with a product that contains
chlorine bleach
 People
who are hospitalized with C. difficile
should have a private room or share a room
with someone who has the same illness
33
 Be
familiar with your facilities policies and
procedures regarding issues of safety and
infection control. Ask whenever you are
uncertain or have a question regarding these
issues.
 Be
Safe
 Practice Safety in the workplace
