Presentation Transcript

  1. Bloodborne Pathogens

  2. Bloodborne Pathogens • microorganisms present in human blood that cause disease in humans

  3. Bloodborne Pathogens • Major Pathogens are: • human immunodeficiency virus (HIV) • hepatitis virus

  4. Hepatitis B (HBV)

  5. Hepatitis Infection facts • Only 50% of people infected each year will become acutely ill • the other 50% show no symptoms & do not know they are infected

  6. Infection facts • 90-94% of people have immune systems that defeat the virus • Those who cannot beat the virus become chronic carriers

  7. Transmission of HBV • most common mode of HBV of transmission is percutaneous (through the skin) or via exposure to mucous membrane

  8. Human Immunodeficiency Virus (HIV)

  9. What is it? • a virus which disrupts and cripples the immune system and leaves the body vulnerable to infections

  10. Comparing HIV to HBV • HBV is hardier than HIV • HBV can remain infectious outside the body for a week or longer • HIV is very fragile outside of the body • risk of acquiring HBV is greater than that of HIV

  11. Comparing HIV to HBV • There is 100 x more concentration of HBV in the blood as compared to HIV • HBV can be transmitted through other bodily fluids (saliva, mucous, etc)

  12. The organization which provides regulations that would protect employees osha occupational safety & health administration

  13. Exposure Prevention

  14. Universal Precautions • all blood and certain body fluids are treated as if known to be infectious for HIV, HBV, and other BBP’s

  15. Pre-event Preparation • providing proper care of existing wounds

  16. Personal Protective Equipment • gloves, gowns, laboratory coats, face masks, and eye protection

  17. Work Practice Controls • altering the manner in which a task is performed to limit exposure

  18. Engineering Controls • removing or isolating the hazard • isolating the worker from the exposure • use of biohazard containers and Sharps containers

  19. General Housekeeping Practices • maintain the work site in a clean and sanitary condition
