The Black Death and other Misfortunes I

Some facts I found about medieval illnesses were too gory to publish on this posting. But some are vital in our understanding of what happened. Like the facts below:

Fleas actually sucked up the plauge through their skin.

Black boils were the first signs of the black death.

Over 30% of Europe's population died in the first wave.

All of these facts found in: (Macdonald, Fiona), How Would You Survive in the Middle Ages?. New York, Franklin Watts, 1995
