Influenza- Epidemiological standpoint

I need a 2-page background information about flu. I would like the paper to include an Epidemiological review/standpoint of the following:
1. What is flu? Different types of flu? Most common types of flu? How does it spread?
2. Recent out breaks of flu in USA and around the world.
3. How deadly it is- which geographical areas/communities are most affected
4. Any treatment, vaccinations, etc. developed in response to the flu epidemic. Which interventions/treatments are currently effective
5. What public health measures or policies have been taken by governmental organizations and hospitals in USA- organizations like Centers for Disease Control (CDC)
6. How all of this affects the public both short term and long term period
