    • Disease name: hepatitis 
    • Pathogen name: Hepatitis A Virus (HAV)
    • Pathogen type: virus
  5. Type of pathogen, pathogen name, disease name:
    Hepatitis B Virus
    • Disease name: hepatitis
    • Pathogen name: Hepatitis B Virus (HBV)
    • Pathogen type: Virus
  6. Type of pathogen, pathogen name, disease name:

    Varicella-zoster Virus (VZV)
    • Disease name: chickenpox and shingles
    • Pathogen name: Varicella-Zoster Virus (VZV).
    • Pathogen type: virus
  7. Type of pathogen, pathogen name, disease name:
    Human Immunodeficiency Virus
    • Disease name: Acquired Immunodeficiency Syndrome (AIDS)
    • Type of pathogen: Virus
    • Pathogen name: Human Immunodeficiency Virus
  8. Which do viruses mutate more rapidly in, RNA or DNA?
    RNA
  9. Viruses have high or low infectivity
    high
  10. 2 effects of herpesviruses in terms of infection longevity
    • 1) establishes latent infection
    • 2) establishes life-long infections.
  11. 2 facts about anti-viral drugs
    • -few drugs exist that, because it's hard to target just them without targeting our own cells.
    • -Anti-viral drugs target virus-specific components and processes.
  12. 1) types of influenza virus (most common)
    1) A (most common), B & C.
  13. Define antigenic drift
    minor mutations that accumulate over time
  14. what is it called when:
    -2 influenza viruses or segmented viruses infect one host cell
    -Progeny of viruses from the cell contain a mixture of genomic segments from each of the viruses
    -major 'mutation' that occurs instantaneously
    -HUGE contributor to flue epidemics/pandemics
    Antigenic shift
  15. difference between antigenic drift and antigenic shift
    • 1) Antigenic drift happens slowly over time, and major contributor to evolution.
    • 2) antigenic shift happens instantly in a cell and are from 2 segmented viruses making 100's of different viruses.
  16. how many phenotypes, and genotypes can occur from 1 influenza co-infection of antigenic shift (not counting random mutations)?
    4 phenotypes, 256 genotypes
  17. Primary and secondary disease of VZV
    Primary: chickenpox, secondary: shingles
  18. what causes clearance of chickenpox
    innate immune system activates CD4, CD8 and B cels, making memory T and B cells.
  19. Is someone vaccinated with VCV infected with the virus once immunized?
    most likely yes. infection occurred but no symptoms appear.
