  1. 1What is the infection rate of influenza in the general population?
    1. A10-20%.
    2. B5%.
    3. C30-80%.
    4. D100%.
  2. 2If a person doesn't have symptoms of influenza, but is infected by the virus, this may be a sign that:
    1. ATheir body is too strong to worry about influenza.
    2. BTheir body is not fighting the infection, and interferon is not activating.
    3. CInfluenza no longer has any symptoms.
    4. DInfluenza has already destroyed the entire immune system.
  3. 3Influenza is commonly transmitted by respiratory droplets. One respiratory droplet (from sneezing or coughing) can have up to:
    1. A100 virions per droplet.
    2. B5,000 virions per droplet.
    3. C1,000,000 virions per droplet.
    4. D600,000 virions per droplet.
  4. 415th century Italian scholars thought influenza was "malathia influenzae per le stelle', or 'a disease influenced by the stars'. This was because:
    1. AInfluenza is a seasonal virus with predictable peaks.
    2. BThe rashes on influenza patients looked like constellations.
    3. CThey thought the gods cursed humanity with influenza.
    4. DInfluenza was thought to only be transmitted at night under starlight.
  5. 5During the Spanish Flu, people were primarily 'hospitalized' to:
    1. AUndergo treatment procedures.
    2. BQuarantine them from uninfected citizens.
    3. CContribute to research.
    4. DCatalogue their symptoms.
  6. 6The Spanish Flu, unlike most common influenza, had an extremely high death rate in this group of people:
    1. AChildren.
    2. BYoung adults.
    3. CElderly.
    4. DMiddle aged.
  7. 7The influenza virus is:
    1. AA segmented virus made out of 8 RNA segments.
    2. BA non-segmented virus made out of a DNA strand.
    3. CA segmented virus made out of 3 RNA segments.
    4. DA non-segmented virus made out of an RNA strand.
  8. 8Haemagglutinin (HA) is the influenza's way of binding to the cell, and Neuraminidase (NA) is how it cuts itself out of the cell.
    1. AVerdadero
    2. BFalso
  9. 9Because influenza is an RNA virus with no proofreading mechanisms, it:
    1. AHas a high error rate of 1:5,000 nucleotides.
    2. BHijacks the DNA polymerase repair mechanisms.
    3. CIs rejected by cells most of the time.
    4. DMutates very slowly and infrequently.
  10. 10If we were out of flu season, and best wanted to prepare for the influenza strain we would be facing the next flu season, we would:
    1. ATry to force the current influenza to mutate, and see what it turns into.
    2. BObserve influenza in the opposite hemisphere.
    3. CGet everyone vaccinated for the previous year's influenza strain.
    4. DStart working on the formula for everlasting summer, so flu season never comes back.
