I had a little bird,
Its name was Enza,
I opened the window,

The Flu had infected humans in the ages of 15-40, seeming strange for most other influenza's had affected elderly and children, but not this flu.
The mortality rate was a near 2.5%, way higher than the previous influenza's that had only been 0.3% or lower.
It's origin is to be thought to be from a rare genetic shift in the influenza in an area in China
