  1. 1. Infectious Diseases
  2. 2. Objectives <ul><li>Differentiate between infectious and communicable disease </li></ul><ul><li>Identify methods of transmission </li></ul><ul><li>Recognize immunosuppressant syndromes </li></ul><ul><li>Differentiate between influenza and common cold </li></ul>
  3. 3. Differentiate between infectious and communicable disease <ul><li>Infectious disease caused by pathogenic microorganism that finds acceptable host where it can grow. Communicable disease is when an infectious disease can be transmitted from one person to another </li></ul>
  4. 4. Methods of Transmission <ul><li>Bloodborne </li></ul><ul><li>Oral/fecal </li></ul><ul><li>Sputum/nasal discharges </li></ul><ul><li>Mucous/cutaneous lesions </li></ul>
  5. 6. Recognize immunosuppressant syndromes <ul><li>Disease result of immune response that fails to distinguish “non-self” from “self” antigens </li></ul><ul><li>Immune response is directed towards “self” and serves as basis for chronic inflammation, which leads to cellular alterations and injury </li></ul><ul><li>Treatment strategies based on interference with responses seen in autoimmunity and hypersensitivity </li></ul><ul><li>Examples include: AIDS, Anaphylactic reactions, systemic lupus erythematosus, Rh isoimmunization and chronic fatigue syndrome </li></ul>

  7. 8. In class assignment <ul><li>Short 5 minute presentation (groups of 3) </li></ul><ul><li>Create story (using infection process diagram as a guide) about transmission of your assigned disease to each member of group </li></ul><ul><li>Presentation should include: name of disease (and any other names known by), how is it caused (type of microorganism), how is it transmitted, how is it treated, 1 interesting feature of disease found from outside source </li></ul>
