Blood borne pathogen

  1. 1. New Richland Fire Department Training & Safety 2007 Pathogens Blood Borne
  2. 2. <ul><li>Approximately 5.6 million workers in health care and other facilities are at risk of exposure to bloodborne pathogens such as human immunodeficiency virus (HIV – the virus that causes AIDS), the hepatitis B virus (HBV), and the hepatitis C virus (HCV) </li></ul><ul><li>OSHA’s Bloodborne Pathogens standard prescribes safeguards to protect workers against the health hazards from exposure to blood and other potentially infectious materials, and to reduce their risk from this exposure </li></ul>Introduction
  3. 3. Who is Covered by the Standard? <ul><li>All employees who could be “reasonably anticipated” as the result of performing their job duties to face contact with blood and other potentially infectious materials </li></ul><ul><li>“ Good Samaritan” acts such as assisting a co-worker with a nosebleed would not be considered occupational exposure </li></ul>
  4. 4. Some Workers Who are at Risk <ul><li>Physicians, nurses and emergency room personnel </li></ul><ul><li>Orderlies, housekeeping personnel, and laundry workers </li></ul><ul><li>Dentists and other dental workers </li></ul><ul><li>Laboratory and blood bank technologists and technicians </li></ul><ul><li>Medical examiners </li></ul><ul><li>Morticians </li></ul><ul><li>Law enforcement personnel </li></ul><ul><li>Firefighters </li></ul><ul><li>Paramedics and emergency medical technicians </li></ul><ul><li>Anyone providing first-response medical care </li></ul><ul><li>Medical waste treatment employees </li></ul><ul><li>Home healthcare workers </li></ul>
  5. 5. Mode of Transmission <ul><li>Communicable diseases are most often caused by either viruses or bacteria </li></ul><ul><ul><li>Viruses cannot reproduce outside of a cell </li></ul></ul><ul><ul><li>Bacteria can reproduce outside of a cell, meaning that they can reproduce on any inanimate object </li></ul></ul>
  6. 6. Two ways of transmission <ul><li>1. Direct Transmission </li></ul><ul><li>2. Indirect Transmission </li></ul>
  7. 7. Direct Transmission <ul><li>Passage of a disease from one person to another through direct contact with infected body fluids </li></ul><ul><ul><li>Across placenta (from mother to child) </li></ul></ul><ul><ul><li>Sexual contact </li></ul></ul><ul><ul><li>Airborne </li></ul></ul><ul><ul><li>Bloodborne </li></ul></ul>
  8. 8. Indirect Transmission <ul><li>Passage of a disease from one person to another without direct personal contact </li></ul><ul><ul><li>Food </li></ul></ul><ul><ul><li>Water </li></ul></ul><ul><ul><li>Airborne </li></ul></ul><ul><ul><li>Bloodborne </li></ul></ul><ul><ul><li>Insect </li></ul></ul>
  9. 9. Chain of Transmission <ul><li>Certain conditions must be met in order for a communicable disease to be transmitted </li></ul><ul><li>You need the following conditions to exist… </li></ul><ul><ul><li>Causative agent </li></ul></ul><ul><ul><li>Mode of transmission </li></ul></ul><ul><ul><li>Portal of entry </li></ul></ul><ul><ul><li>Receiving host </li></ul></ul>
  10. 10. Causative Agents <ul><li>Bacteria </li></ul><ul><li>Virus </li></ul><ul><li>Fungi </li></ul><ul><li>Protozoa </li></ul>
  11. 11. Mode of Transmission <ul><li>Efficient mode of transmission </li></ul><ul><ul><li>(ex: Injection directly into the bloodstream) </li></ul></ul><ul><li>Inefficient mode of transmission </li></ul><ul><ul><li>(ex: Splash onto mucous membrane of eye or nose) </li></ul></ul>
  12. 12. Portal of Entry <ul><li>Respiratory tract </li></ul><ul><li>Mucous membranes </li></ul><ul><li>Parenteral </li></ul><ul><li>Gastrointestinal tract </li></ul><ul><li>Genitourinary tract </li></ul><ul><li>Transplacental </li></ul><ul><li>Non-intact skin </li></ul>
  13. 13. Receiving Host <ul><li>The receiving host is the person who has been… </li></ul><ul><li>Don’t Let this be YOU! </li></ul>EXPOSED!
  14. 14. Breaking the Chain of Transmission <ul><li>Only you can break the chain by following your services… </li></ul>INFECTION / EXPOSURE CONTROL PLAN
