There was a little girl, and she had a little bird,
And she called it by the pretty name of Enza;
But one day it flew away, but it didn't go to stay,
For when she raised the window, in-flu-Enza.
Look at it this way - The Plague of Athens, The Plague of Justinian, The Black Death, The Spanish Lady, the Cocoliztli epidemic of 1576 - look each one up and you'll see a crisis that makes any war look pretty pathetic in comparison. The Spanish Lady wiped out something like one in every 20 of the worlds population, vastly more the total death toll of world war 1 which finished about the same time (troops returning home to far-flung locations across the planet was probably a reason it spread so quickly). History lessons don't really teach much about these things. They're not glamorous. They're not patriotic. A teacher can't talk about the motivations or machinations of kings or queens in reference to a plague.
People simply die, horribly. All in pretty much the same way.
But these events have done more to shape human history than anything else according to some. And with antibiotic resistance on the rise, they might still...
...sleep tight.
