How the Black Death was started.

Well in 1347 a ship came back to Italy from Asia.  Long trip right?  Well the ship had black rats aboard and the black rats were carrying diseased fleas carring the disease called the Black Death.  After the Italians ship docked in Italy the black rats got off the ship with the fleas still on them.  When the black rats got by the people the fleas gave the disease to the humans and the humans gave the diseas to eachother.  The humans called the Black Death the Black Death because the Italians sailed back to Italy on the Black Sea.
