Roughly 1 in 6 humans on the planet to die from the flu over a 6 month period.
I have a hard time believing this, regardless of historical precedent, but stranger things have happened.
... In 1918, when the world population was 1.8 billion, an influenza epidemic incapacitated 1 billion and killed 20 to 40 million, all within the space of 8 weeks. ...
Found the following on GOOGLE.
One thing is, lots of the deaths are from pneumonia etc. and related to poor general health knowledge. I imagine in the developed world the odds are better. Although with 5 patients for every hospital bed it may not? Third world (women and children) would be hardest hit.
World War I wasn't won - it was "called" on account of the flu.

1 billion is just the case fatality rate rate (70%)

times the number infected (1.5 - 2 billion).
It's not hard to get to 1 Billion dead.
