  1. Bloodborne Pathogens

  2. What is a bloodborne pathogen? • A microorganism or virus that is carried in the blood • These pathogens can be transmitted if you come in contact with blood from an infected individual

  3. What are the types of bloodborne pathogens I need to know about? • There are a few types of bloodborne pathogens you need to be aware of • Hepatitis B (HBV) • Human Immunodeficiency Virus (HIV)

  4. Hepatitis B (HBV) • A virus that is transmitted via direct contact with blood • You may be asymptomatic for up to 6 months after the time of infection. Early symptoms may include: • appetite loss • fatigue • fever, low-grade • muscle and joint aches • nausea and vomiting • yellow skin and dark urine due to jaundice

  5. Hepatitis B (HBV) • Long term infections may result in cirrhosis of the liver • There is NO cure for Hepatitis B

  6. Hepatatis B (HBV) Vaccine • There is a vaccine available for HBV • The vaccine is made from the Hepatitis B virus, but cannot cause HBV infection • The vaccine is given in 3-4 shots • The vaccine provides long-term protection from HBV, possibly life-long

  7. Human Immunodeficiency Virus (HIV) • Can be transmitted by direct contact with blood • HIV attacks the immune system, causing infected individuals to become susceptible to infections that eventually cause death • Early symptoms include • fever • aching muscles and joints • sore throat • swollen lymph nodes • weight loss

  8. Human Immunodeficiency Virus (HIV) • HIV cannot remain infectious for very long outside the body • The primary concern is exposure to fresh blood • There is NO cure for HIV • There is NO vaccine for HIV

  9. How are bloodborne pathogens transmitted? • There are a variety of ways to transmit bloodborne pathogens, including • contact with infected blood • semen • vaginal secretions • cerebrospinal fluid • saliva

  10. Bloodborne pathogens and your skin • Normally, unbroken skin forms a mechanical and chemical barrier against invasive pathogens like bloodborne pathogens • Bloodborne pathogens can enter your skin through • abrasions • acne • cuts • damaged or broken skin such as sunburn or blisters • open sores

  11. Mucous membranes • Bloodborne pathogens can also be transmitted across mucous membranes found in the eyes, mouth, and nose

  12. How do I prevent infection? • Always use Universal Precautions!!! • Assume all blood is infectious • Use the following precautions to prevent infection • Wear gloves • All sharp devices used to collect blood must be placed in a biohazard container • Any blood on surfaces must be cleaned with 10% bleach solution • Any item that has blood on it should be disposed of in a biohazard container

  13. Follow these rules to prevent infection • Treat all blood as potentially infectious • Always wear gloves • Replace gloves that are torn or punctured • Properly disinfect the area you are working in • Properly dispose of all blood-contaminated items • Wash your hands immediately after removing gloves

  14. Other Considerations • Cover any cuts or sores on your hands with a bandage • NEVER eat or drink in lab • NEVER apply cosmetics or lip balm in lab • NEVER handle contact lenses in lab

  15. Decontaminate and Sterilize • All surfaces that may have come in contact with blood MUST be decontaminated and sterilized by washing the area with 10% bleach solution

  16. How do I clean up a blood spill? • Cover the spill with paper towels • Carefully pour 10% bleach solution over the towel-covered spill • Let stand for 10 minutes • Wearing gloves, collect the waste and dispose of in a labeled biohazard receptacle

  17. What do I do if I am exposed? • Wash the affected area with soap and water • Flush the mouth, eyes, and nose for 15 minutes if blood splashes in any of these mucous membranes • Report the exposure to your lab instructor immediately • Follow the instructions given to you by Campus Safety concerning seeking medical attention

  18. Summary • ALWAYS use Universal Precautions • Thoroughly clean your work area with 10% bleach solution • Properly dispose of all wastes • Report any suspected exposure • Follow instructions about seeking medical attention
