Top Ten Killers 1. Cardiovascular (CVD) 2. Cancers 3. Stroke (cerebrovascular) 4. Lower Respiratory 5. Accidents 6. Diabetes 7. Alzheimers 8. Flu and Pneumonia 9. Kidney Disease 10. Infections

Communicable vs. Non Communicable:  Caused by direct or indirect spread of pathogens from one person to another. They enter and multiply within the human body.

Types of Communicable Diseases  Cold and flu  Tuberculosis (affects lungs)  Strep Throat  Encephalitis (inflammation of the brain)  Meningitis (inflammation of the membranes that cover the brain)  Polio (impacts the CNS causes paralysis)  Measles (cold, fever, rash)  Mono (fatigue, swollen glands)  Hepatitis (inflammation of the liver)A, B & C

Caused by Pathogens  Bacteria (single cell microorganism) –They enter the body and multiply rapidly through cell division. Can live anywhere – air, soil, water – some produce toxins.  Viruses (genetic material coated by protein) –Are not living cells but attach themselves to living cells (hosts) and injects its genetic material into that cell, makes copies and spreads to other cells

Causes continued  Rickettsias (similar to bacteria) –Most are found in the intestinal tracts of insects (fleas, ticks, mites and also mice) and are passed through bites or through feces deposited on the skin.  Fungi (plant like organisms) –Ring worm or athletes foot. They prefer dark, damp environments and invade deep tissue like hair, nails and skin.

How are communicable diseases spread?  DIRECT CONTACT –People, Animals or Environment  INDIRECT CONTACT –Contaminated objects – table, door handles, eating utensils, tooth brush, needles, etc. –Vectors (flies, mosquitoes & ticks) – transfers pathogens from person to person –Water & Food

Prevention  Wash hands  Food Handling  Strong Immune System  No Sharing (utensils, make up, combs etc)  Contact with people, etc.  Stress…..  Immunizations

Our Bodies Ways of Preventing Communicable Diseases  Physical barriers (skin, mucus, cilia etc)  Chemical barriers (enzymes in saliva and gastric juices)  Immune System Response –Inflammatory Response –Antigen – substance that is capable of triggering an immune response

Webquest the following:  Define: –Inflammatory response –Phagocyte –Antigen –Immunity –Lymphocyte –Helper T cells –Killer T cells –Suppressor T cells –Antibody –Vaccine –Active immunity –Passive immunity –Vaccines

Webquest the Following Cont.  If a lymph node is swollen when should you call the doctor?  In your journal draw where your lymphocytes concentrated? (6 places)  How to care for your immune system? (7 ways)

Disease Interview  Interview someone who suffers or has suffered from a non- communicable disease. (family, friend etc)  Over phone, in person via .  Develop 10 thought provoking questions and format Q & A’s into magazine format.
