The Black Death
"Viral" isn't a nice word in 14th century Europe.
FEAR THE BLACK DEATH
A absolutely terrible plague swept through Europe during 1347-55. It killed approximately 75 million Europeans, which is about 1/3 OF THE EUROPEAN POPULATION!
A QUICK SUMMARY
What it looked like!
An hand that is swelling and rotting.
What caused it!
Many infections were carried out by fleas that were carrying infected rat blood.
Worse than Ebola ever was!
Just some humor.
