    1. 1. BIOHAZARD TRANSMISSIONKIM ENGLAND
    2. 2. WHAT IS A BIOHAZARD? Typically a pathogen, especially one used in or produced by biological research. BIOHAZARD TRANSMISSION The health risk posed by the possible release of such a pathogen into the environment. 2
    3. 3. WHAT IS A PATHOGEN? An infectious agent A microorganism; most commonly known as a BIOHAZARD TRANSMISSION “germ” There are several categories, including:  Fungi  Bacteria  Viruses  Parasites 3
    4. 4. WHAT DO PATHOGENS DO?VIRUSES BACTERIA BIOHAZARD TRANSMISSION Cannot reproduce   Grow, reproduce, and take over cells divide in cells Make copies in those  Cause damage cells  Toxins Cells burst  release  Growth viruses 4
    5. 5. HOW ARE PATHOGENS SPREAD? SOMEONE HAS AN INFECTION BIOHAZARD TRANSMISSION SECOND PATHOGEN PERSON LEAVES DEVELOPS INFECTED INFECTION PERSON PATHOGEN REACHES ANOTHER 5 BODY
    6. 6. HOW ARE PATHOGENS SPREAD? Sufficient amount of pathogen Suitable environment for growth of pathogen BIOHAZARD TRANSMISSION “Mode of Transmission”  Physical contact  Secretions  Excretions  Body fluids  Tissues  Through air  Through food and water  Indirect contact  Vectors 6  Contaminated objects
    7. 7. HOW ARE PATHOGENS SPREAD?BLOODBORNE AIRBORNE BIOHAZARD TRANSMISSION Spread through  Transmitted through contaminated droplet nuclei in the air substances  Coughing  Sneezing  Blood  Saliva, vomit, or urine  Three types: containing blood viral, bacterial, and  Semen fungal  Ex.  Breast Milk Meningitis, influenza, p Ex. HIV and Hepatitis B neumonia, tuberculosis and C 7
    8. 8. PREVENTING EXPOSURE “Universal Precautions”  Treat all blood and potentially infectious materials as BIOHAZARD TRANSMISSION though they are infectious  Create a barrier between you and infectious materials Personal Protective Equipment (if these resources are available/relevant)  This creates a barrier  Gloves, fluid-resistant apron, safety goggles, face mask, long-sleeved shirt, long pants, closed-toed shoes 8
    9. 9. PREVENTING EXPOSURE Bloodborne Pathogens  Dispose of contaminated materials appropriately BIOHAZARD TRANSMISSION  Biohazard bags  Sharps containers  Clean and disinfect all equipment and work surfaces  10% bleach solution for 10 minutes Airborne Pathogens  Avoid people who are ill  Wash hands often  Use sanitizer if soap and water is unavailable 9
    10. 10. PREVENTING TRANSMISSIONBLOODBORNE AIRBORNE BIOHAZARD TRANSMISSION Avoid making direct  Stay home when sick contact with uninfected  Wash hands regularly persons  Cover coughs and Avoid making indirect sneezes contact  Cover any open skin you may have 10
    11. 11. WHY IS PREVENTION IMPORTANT?Each of our immune systems is a unique andincredible system made to fight infections and BIOHAZARD TRANSMISSIONdiseases to keep up healthy and safe. Althoughcatching a cold every now and again isn’t a bad thing,there are pathogens in this world that have proven tobe fatal. It is important to control such diseasesbefore they are able to spread and claim lives. Theonly way we can control these are to recognize howwe expose ourselves to them, and if we have them,how we transmit them. Following simple hygienerules and avoiding people if we/who are sick are bothimportant preventative measures in keeping 11pathogenic populations down.
