potentially infectious material (OPIM) that are able to
cause disease in humans
Hepatitis B virus (HBV, HepB)
 Hepatitis C virus (HCV, HepC)
 Human immunodeficiency virus (HIV)


Less commonly, human T-lymphotropic virus (HTLV-1),


Implemented in 1991 by the Occupational Safety &
Health Administration (OSHA)

29 CFR 1910.1030
http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=10051

Revised in 2001 – safe sharps devices, maintain a log of
injuries from contaminated sharps

UF follows OSHA requirement


General and workplace-specific training
Completed BEFORE individual is assigned to tasks with the
potential for BBP exposure and ANNUALLY thereafter

In addition to training, individuals with potential exposure
must also have:

Access to the regulatory text and an explanation of its contents
http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=10051


A woman in KY was arrested and charged with public
intoxication (March 2010)

While changing into an inmate uniform, she squirted a
stream of breast milk into the face of a female deputy

The press release sparked a debate when it was noted
that the deputy was able to “clean the biohazard off of
her”

Does this constitute an occupational exposure?

Yes, breast milk is considered OPIM

All human blood or OPIM is treated
as infectious
Use:
Safety Equipment
Safe Work Practices
Personal Protective Equipment
(PPE)

Standard precautions = universal
precautions + body substance
isolation. Applies to blood & all other
body fluids, secretions, excretions
(except sweat), nonintact skin, and
mucous membranes

Human blood and OPIM

Objects/items contaminated by blood or OPIM

Unfixed human tissues/organs (other than intact
skin)

Cell or tissue cultures that may contain BBP agents

Blood/tissues from animals infected with BBP agents

Use Universal Precautions for all human cell lines

ATCC started testing newly manufactured/deposited cell
lines for common viral pathogens (HIV, HepB, HepC,
HPV, EBV, and CMV) in January 2010

Many infectious agents yet to be discovered and for
which there is no test


Remember HIV?
What about XMRV?


Spread through direct contact with infected
fluids (blood, semen, vaginal fluids)
Infection may be acute or chronic




body
~4.3-5.6% of Americans have been infected with HepB
5-10 % of adults will develop chronic infection; ~1.2 million people
with chronic HBV
15-25% develop cirrhosis , liver failure, or liver cancer (~ 3000
deaths/year)
Many people (~50%) are asymptomatic; if symptoms
occur they include:
Fever
Abdominal pain
Fatigue
Loss of appetite
Nausea
Vomiting
Jaundice
Joint pain
Dark urine

Percutaneous

~30% of these exposures results in infection

Mucosal exposure to blood/body fluids

Exposure to nonintact skin from contaminated surfaces
and equipment – HBV can remain infective in dried
blood at RT for at least 1 week (MacCannell et al., Clin Liver Dis
2010; 14:23-36)

Get vaccinated!

Universal Precautions


Given to newborns, 120 million people
in U.S. have received at least one dose
>95% develop immunity after full series
(3 doses given at 0, 1, 6 mos)
In Gainesville, free @UF SHCC



Bring completed
Acceptance/Declination statement with
you
http://www.ehs.ufl.edu/Bio/BBP/TNV.pdf
If you decline, can change mind at any
time

Health-care workers or public safety workers at high risk
for continued percutaneous or mucosal exposure to blood
or body fluids, HBV research lab workers

Performed 1-2 months after dose #3




HepB surface antibody (anti-HBs) ≥ 10 mIU/mL - immune
Anti-HBs < 10 mIU/mL – revaccinate (3 doses) and retest anti-HBs
Still negative – nonresponder, need HBIG after exposure
Previously vaccinated but not tested? Test for anti-HBs
after an exposure; if negative, treat as susceptible.

Transmitted primarily through contact with
infected blood

Many people asymptomatic (symptoms
similar to HepB)

~1.8 % of Americans have been infected
with HepC, 3.2 million chronically infected


~ 12,000 deaths/year
Leading indication for liver transplant in U.S.

Percutaneous injury, esp. with deep punctures or extensive
blood exposures

~2% develop infection

Mucosal/nonintact skin exposures rarely documented

Proper cleaning/disinfection of surfaces important

HCV in dried blood samples remains infective for at least 16 hours
(Kamili et al., Infect Control Hosp Epidemiol 2007; 28:519-524)

Universal Precautions for Prevention!


NO VACCINE
Antivirals (interferon/ribavirin) can have serious side effects,
treatment lasts 24-48 weeks


Transmitted through contact
with infected blood/OPIM
1° infection



Asymptomatic phase
Symptomatic phase


transient, non-specific illness
(fever, malaise, muscle pain,
sore throat)
↑ susceptibility to opportunistic
infections, nonspecific
constitutional symptoms (night
sweats, weight loss, anorexia,
fever)
Advanced (AIDS)

one or more opportunistic
infections, CD4<200 cells/µl
 > 1 million living with HIV/AIDS
 ~56,000 new infections/year
 ~20% don’t know they are infected
 Florida ranks 3rd among states
in the number of reported
HIV/AIDS cases

Risk for HIV transmission after:



Percutaneous injury – 0.3%
Mucous membrane exposure – 0.09%
Nonintact skin exposure – low risk (< 0.09%)
57 documented occupational
infections in U.S. (139 possible infections)
84% resulted from percutaneous exposure!

No cure

No vaccine
