  1. Infectious Disease Definition: Diseases transmitted(spread) by pathogens(germs)

  2. Infectious Disease • The diseases are contagious -capable of being transmitted by bodily contact with an infected person or object • The diseases are communicable-capable of being transmitted by infection 

  3. Pathogens • Three types • Virus: invades body cells, then cells increase and break open with virus moving on to other cells..smallest and most numerous • Bacteria: produces infection causing poisonous waste • Fungus: attach to body cells causing damage and robbing them of their nutrients

  4. Types of infections • http://images.google.com/imgres?imgurl=http://health.utah.gov/epi/morbidity_report/2007/jun/chart2_jun07.jpg&imgrefurl=http://health.utah.gov/epi/morbidity_report/2007/jun/Jun07.html&h=718&w=1014&sz=94&hl=en&start=34&um=1&tbnid=mosVsSFt5eFKtM:&tbnh=106&tbnw=150&prev=/images%3Fq%3Dcommunicable%2Bdisease%26start%3D20%26ndsp%3D20%26um%3D1%26hl%3Den%26rls%3DRNWE,RNWE:2006-04,RNWE:en%26sa%3DN

  5. How Pathogens are Spread • Infectious diseases spread through two types of contact • Direct contact • Person to person – shaking hands, touching, etc….. • Animal to person – bites or stings • Mother to unborn child • Indirect contact – inanimate objects…doorknobs, faucet handle, table tops • Water • Air • Food-temperature(undercooked or unwashed foods)

  6. Methods to prevent spread of germs • Wash your hands frequently • Get vaccinated • Use antibiotics sensibly • Stay home if signs and symptoms of infection • Be smart when preparing food • Keep Hot zones in home clean – areas with concentration of bacteria – bathrooms and kitchen • Don’t share personal items- toothbrush,hair brush, razor

  7. Flu Virus • http://images.google.com/imgres?imgurl=http://www.3dscience.com/img/Products/3D_Models/Biology/Viral/Influenza/supporting_images/3d_model_biology_influenza_web2.jpg&imgrefurl=http://www.3dscience.com/Resources/Influenza_Virus.php&h=300&w=300&sz=53&hl=en&start=1&um=1&tbnid=_KoNzUhnYanZqM:&tbnh=116&tbnw=116&prev=/images%3Fq%3Dflu%2Bvirus%26um%3D1%26hl%3Den%26rls%3DRNWE,RNWE:2006-04,RNWE:en

  8. Body Defenses • Skin • Blood • Antibodies – white blood cells

  9. Anti-biotics • Antibiotics are the first line of defense against many infections. But overusing or misusing antibiotics can cause more harm than good. • Antibiotics are only effective against bacterial infections, certain fungal infections and some kinds of parasites. Most infections result from either bacteria or viruses. Antibiotics can't help you if a virus is responsible for your illness.
