The effects of the dreaded yellow fever were recorded by James Stanley Gilbert in his 1911 poem:

Yellow Eyes You are going to have the fever,
Yellow eyes!
In about ten days from now
Iron bands will clamp your brow;
Your tongue resemble curdled cream,
A rusty streak the center seam;
Your mouth will taste of untold things,
With claws and horns and fins and wings;
Your head will weigh a ton or more,
And forty gales within it roar!
