I think that the more you travel and interact with others, the greater your natural immunity becomes to mutating viral infections.

The speed and intensity of HUMAN travel now speed the mutation of the flu and also act to innoculate large portions of humanity from greater threats.

In 1918 everyone was mostly extremely provincial. Living in their villages and traveling very little. Antiseptics, cleanliness were not in abundance in even the most sophisticated city centers. This made folks more vulnerable to the influenza.

I experienced last year's flu and there's that point where you feel your body cannot take much more - a point I had never felt before with the flu - but then it pulls through. As terrible as it is I feel that this severe, but survivable, flu provides a whole new level of innoculation for those who get it.

If one hasn't experienced it yet, it's nasty but fast:

Fever is high, stomach is hit hard and the shakes are nearly unstoppable. I suspect that this flu has already been exposed to parts of the bird flu viral strain. Too much of it was entirely new to the body and it had a much faster reproduction rate, challenging the body to keep up. It was unlike any flu I've ever had.

However, once the frequency signature is recorded and identified, the white blood cells get updated and now prevent infestations.

Once we start to realize viruses also emit frequency signatures and that our cells record them as they encounter them and understand their harmful nature, we begin to understand the as yet unfathomable complexity of our immune system.

Flock animals are provincial beasts and have no such protection, nor have they the same capacity for resistance. This is why such high fatality rates occur in farm populations of chickens, etcetera.

So 2 billion human deaths is a very high estimate. I suspect it will harm those that get around less or interact in very limited manners.

Senior populations are always the most vulnerable for these reasons.

The speed at which this virus changes its signature is both a curse and blessing. It may 'burn out' faster as it regenerates with new combinations of proteins. There is always the possibility that it makes itself less potent an reassimilates with more familiar human viral traits.

None of this means we should cease proactive ways of dealing with this threat.
