? about the population during the spanish flu

I was just watching end days on history channel,

According to the narrator 600 million died from the flu and only 3% of the people that got it died from it.

Here is the ?

What is the total population at the time before the flu started?

lol not 20 billion

are you sure it didn't say 600 million infected? 20 million dead sounds like a more reasonable number.

let's see: 3% of people are already very unhealthy & weak, and they are the ones who die of such diseases.

Now Ebola, with (i think) 95% mortality, that's kind of scary.

Spanish Flu, or any other flu, is not scary.
