Bloodborne Pathogens Bloodborne Pathogens are microorganisms such as
Bloodborne Pathogens • Bloodborne Pathogens are microorganisms (such as viruses) transmitted through blood, or other potentially infectious material such as certain bodily fluids (semen, breast milk, etc. ) or tissues.
Bloodborne Pathogens • Bodily fluids, especially those visibly contaminated with blood, are capable of causing disease. • Pathogens can enter your body through a cut in the skin, through your eyes or mouth. • Can also be transmitted sexually • Main diseases of concern are Hepatitis B (and C) virus, and HIV (AIDS virus).
Human Immunodeficiency Virus (HIV) • HIV attacks your body’s ability to protect itself against disease • Initially no visible signs of having the virus • Most people with HIV develop AIDS (acquired immune deficiency syndrome) • There is no vaccination for HIV
HIV • Virus lives outside the body only a few hours • 4 modes of transfer: 1 blood 2 semen 3 vaginal secretions 4 breast milk
HIV 10 -50 virus particles per ml of blood

Hepatitis B (and C) Hepatitis B Virus • Up to 100 times easier to catch than HIV • Unlike HIV, can live outside of body for several days
Concentration of Hepatitis B Virus in Various Body Fluids
Hepatitis B • 1, 000 - 1, 000, 000 virus particles per ml of blood • Virus can live outside the body for several days
HIV vs. Hepatitis B
Hepatitis C • 3 -4 million carriers • Disease can incubate for decades • By 2010 may affect more Americans each year than AIDS • HCV not related to the viruses that cause HBA and HBV
Hepatitis C
Hepatitis C • Risk Factors: – Long-term kidney dialysis – Sex with multiple partners – Tattooing or body piercing with shared needles or unsterilized equipment – Intranasal cocaine use with shared straws Pamela Anderson claims her infection came from a tattoo needle
Hepatitis B (and C) • There is no cure for Hepatitis B or C… • but unlike HIV, there is a vaccination for Hepatitis B. (There is no vaccination for Hepatitis C)
HBV and HCV • Liver is located behind the lower ribs on the right side of your abdomen • Weighs about 3 pounds and is roughly the size of a football. • If infected with HBV, the liver often becomes tender and enlarged
Some signs and symptoms of HBV and HBC include: • Flu-like symptoms • fatigue normal • jaundice • severe pain in joints • lung disease Yellow from jaundice • inflammation of liver • inflammation on and ulcers of the colon • may be asymptomatic (i. e. no symptoms indicated)
Hepatitis Acute: 6 -8 weeks, 90% – 30 -40% with acute HBV have no idea how or when they became infected – 5 -15% of infected carry virus for longer than 6 months (carriers) Chronic: Life, 10% – Hepatitis B carriers are people infected with HBV and never fully recover. They carry the virus and can infect others for the rest of their lives – Approximately one million people in the US carry HBV
Risk Factors for Acute Hepatitis B
Hepatitis B • “The risk of contracting Hepatitis B from a single needlestick contaminated with blood from a person with known Hepatitis B ranges from 6% to 30%. ” • “Approximately 10% of those infected become chronic carriers who can infect their families and friends. They have up to 300 times greater than normal risk of developing liver cancer. ” • “Every year, approximately 5, 000 Americans, die of HBV or its complications.
Statistics from Milwaukee Journal/Sentinel –“… 1 in 300 infected with HIV” Milwaukee Journal/Sentinel, July 7, 1996 – “one in 20 people has or has had Hepatitis”
How Bloodborne Pathogens Spread on the Job • By a sharp object that is contaminated by the virus when it cuts or punctures your skin.
How Bloodborne Pathogens Spread on the Job • When a contaminated object touches inflamed skin, acne, skin abrasions • When you touch a contaminated surface and then touch your eyes, nose, mouth, or open wounds or inflamed skin
How to Reduce Your Risk • Only PPS Employees at moderate risk are included in the campus Bloodborne Pathogens Exposure Control Plan. • Employees in the plan can receive HBV vaccinations at no cost. • There are specific training, engineering, and work practice controls for those potentially at risk of exposure to BBP on the job.
How to Reduce Your Risk UNIVERSAL PRECAUTIONS/ STANDARD PRECAUTIONS: – A system of infection control which assumes that all human blood and certain body fluids are treated as if known to be infectious.
Use Spill Kit for Clean-up Kit Includes: • • Face Mask Gloves Goggles Sharps Disposal Container Voban Fluid Control Solidifier Personal Safety Equipment Cleaning Pads
How to Reduce Your Risk • Don’t Recap Needles
How to Reduce Your Risk • Do not bend, shear, break or recap needles • If you must recap, use onehanded method
How to Reduce Your Risk • Needles and other sharps must be discarded in rigid, leak-proof, puncture resistance containers
How to Reduce Your Risk • When emptying trash containers, do not use your hands to compress the trash in the bag.
How to Reduce Your Risk • Lift and carry the trash bag away from your body
How to Reduce Your Risk • Do not eat, drink, smoke, apply cosmetics or handle contact lenses in areas where there is the possibility of exposure to BBP, such as in UWM labs
Personal Protective Equipment • Gloves, masks, eye protection, CPR microshields
Body Fluid Cleanup Procedures • Get Spill Kit from Janitorial Closet • Put on gloves.
Body Fluid Cleanup Procedures • If splashing is anticipated, wear protective eyewear and mask
Body Fluid Cleanup Procedures • Remove visible material with absorbent towels
Body Fluid Cleanup Procedures • Area should be decontaminated for 10 minutes • Once the area has been disinfected, dry area with absorbent towels and dispose of towels in regular trash
Body Fluid Cleanup Procedures • Glove removal and disposal technique
Glove Removal and Disposal • Grip one glove near the cuff and peel it down until it comes off inside out. Cup it in the palm of your gloved hand. • Place two fingers of your bare hand inside the cuff of the remaining glove.
Glove Removal and Disposal • Peel that glove down so that it also comes off inside out and over the first glove. • Properly dispose of the gloves.
Body Fluid Cleanup Procedures • Wash hands well.
Vaccination • • • Very low risk vaccine Three doses over 6 months Must receive all three doses >79% effective Free to employees May decline vaccine (but must sign waiver) • May receive vaccine later
Accident/Injury Report • Complete report as soon as possible after incident • Turn in to your supervisor • Form is submitted to Workers Compensation
