BLOODBORNE PATHOGENS DEFINED
• Disease-causing microorganisms that may
be present in human blood or OPIM
(other potentially infectious material)
– Viruses
– Bacteria
– Parasites
MODES OF TRANSMISSION

blood or OPIM on:
– mucous membrane
– non-intact skin
• cuts, abrasions, burns
• acne, rashes
• papercuts, hangnails
– contaminated sharps
RISK OF EXPOSURE
• Objective of BBP standard is to minimize
or eliminate the hazard posed by work
that may expose one to blood or OPIM
RISK OF EXPOSURE
• If a risk of exposure exists one should
know:
–
–
–
–
if there is a way to prevent infection
symptoms and course of infection
availability of counseling
availability of post-exposure treatment &
follow-up
OCCUPATIONAL EXPOSURE INCIDENTS
• Occupational contact with blood or OPIM is
considered an exposure incident
• If an exposure occurs:
–
–
–
–
–
wash with soap & water
report incident
document incident
seek “immediate” medical evaluation
follow employer’s exposure control plan
IMMEDIATE MEDICAL EVALUATION
• “Immediate” means prompt medical evaluation and prophylaxis
• An exact timeline cannot be stated
• Time limits on effectiveness of prophylactic measures vary
depending on the infection of concern
Minimal Information to Report
• Work practice being
• Date and time of incident
followed
REPORTING AN INCIDENT
• Job classification
•
Procedure
being
performed
• Location in the worksite where
• PPE in use
incident occurred
MEDICAL EVALUATION POST EXPOSURE
•
•
•
•
•
Entitled to confidential medical evaluation
Personal decision about blood testing
Blood may be tested only with consent
Blood may be stored for 90 days, while considering testing
Interpretation of any test results occurs with health care provider
BLOOD TESTING
• Blood may be tested for antibodies to:
–
–
–
–
Human Immunodeficiency Virus (HIV)
Hepatitis C Virus (HCV)
Hepatitis B Virus (HBV)
Other disease-causing organisms
SPECIFIC BLOODBORNE PATHOGENS
•
•
•
•
•
Definition
Signs and symptoms
Course of infection
Prevention and control
Post-exposure prophy-laxis and followup care
HIV DEFINED
• HIV is Human Immunodeficiency Virus
• HIV can cause acquired immune deficiency syndrome
(AIDS)
• Risk of HIV infection from a puncture injury exposure to
HIV infected blood is very low -- 0.3%
SIGNS & SYMPTOMS OF HIV
• Signs and symptoms include:
–
–
–
–
Weight loss
Night sweats or fever
Gland swelling or pain
Muscle and/or joint pain
• Cannot rely on signs and symptoms to confirm if one is
infected
COURSE OF INFECTION WITH HIV
• Incubation period from HIV infection to AIDS can be 8 to
10 years
• Varies greatly among individuals
HIV PREVENTION
• There is no vaccine to prevent HIV infection
• Follow Universal Precautions
HIV POST-EXPOSURE PROPHYLAXIS & FOLLOWUP
• No cure for HIV infection
• Testing schedule for HIV antibodies
– at time of exposure
– at 3 months
– at 6 months
• HIV antibodies usually become
detectable within 3 months of
infection
• Treatment requires health care
provider
• OSHA requires treatment that meets
most recent CDC guidelines
HCV DEFINED
•
•
•
•
HCV is Hepatitis C Virus
It affects the liver
It is the most common chronic bloodborne infection in US
Risk of HCV infection after exposure to HCV infected blood is
1.8%
• 70 to 75% of those with acute HCV infection have no symptoms
SIGNS & SYMPTOMS OF HCV
•
•
•
•
•
•
Jaundice - yellow color to skin and whites of eyes
Fatigue
Headache
Abdominal Pain
Loss of appetite
Nausea and vomiting
COURSE OF HCV INFECTION
• Incubation period averages 7 weeks
• Chronic liver disease may occur in 70% of those
infected with HCV
HCV PREVENTION
• No vaccine exists to prevent HCV infection
• Follow Universal Precautions
HCV POST-EXPOSURE PROPHYLAXIS & FOLLOW-UP
• No cure for HCV
• No post-exposure pro-phylaxis
recommended
• Tests for HCV anti-bodies & liver
function recommended at time of
exposure
• Tests should be repeated 4-6 months
post exposure
• Treatment of HCV requires a health
care provider
• OSHA requires treat-ment that meets
most recent CDC guidelines
HBV DEFINED
• HBV is Hepatitis B Virus
• It affects the liver
• Prevalence of HBV infection among healthcare workers is 10
times greater than HCV infection
SIGNS & SYMPTOMS OF HBV
• Jaundice - yellow color to the skin and whites of
eyes
• Fatigue
• Headache
• Abdominal Pain
• Loss of appetite
• Nausea and vomiting
COURSE OF HBV INFECTION
• Incubation period averages 12 weeks
• Most cases of HBV resolve without
complications
• Chronic liver disease may occur in 6 to 7%
of those infected with HBV
HBV PREVENTION
• A vaccine does exist to prevent HBV infection
• Employers are required to offer HBV vaccination HBV
vaccination to employees covered under BBP standard.

than 7 days after exposure
• Exposed person should receive
HBV vaccine
• Treatment requires health care
provider
