  • Pathogens
    • Spread
      • Airborne Pathogens are passed on through the air by inhalation.
      • Ingestion Is when we eat or drink contaminated food and water
      • Direct contact is when thins are passed from one person to another by touching of the skin.
      • Body fluid can be contaminated blood or fluids from sexual intercourse or ever saliva!
      • Vectors are things like mosquitos which carry he disease from one person to another
    • Types of Pathogens
      • Bacterium are single cellular, prokaryotic cells. Bacteria produce toxins.
      • Viruses can take over cells. Viruses are alive!
      • Fungi are Eukaryotic cells that feed on dead or decaying materials
      • Protoctists  unicellular organisms with a nucleus.
    • Prevention
      • Protective clothing
      • Isolate infected person(s)
        • Stereliliseing
      • Catch it, Bin it, Kill it
      • Extermination of potential vectors
      • Safe burial
      • Clean equipment (needles)
    • Treatment
      • To treat Fungi we use creams and powders because they are on the skin's surface
      • Viruses are very hard to treat due to their tendency to take over cells and explode them. This means there is no way to just treat infected cells.
