So it sounds like a pretty good match.
The flu, or influenza, is a contagious respiratory infection caused by the influenza virus (not to be confused with Haemophilus influenzae, an opportunistic bacterium that can cause secondary infections following sicknesses, such as the flu).
In the US, flu forces 140,000 to 710,000 people into hospitals and causes 12,000 to 56,000 deaths annually.
The hardest hit are children, the elderly, and people with compromised immune systems.
Flu virus sickens and kills by getting into our airways and storming cells in the lining of our respiratory tracts.
After quietly running amok for one to four days (the incubation period), symptoms begin.
