The Black Death was caused by several different strains of plague.
These were carried in fleas on black rats in the fourteenth century. It
was always fatal, carrying a 100% mortality rate when not treated by
antibiotics. The disease originated in the dry plains of Central Asia
and traveled along trade routes. It was carried by the rats which were
common in ships at the time.
The fleas gut is blocked up by the Yersinia pestis bacterium which causes plague. This causes it to regurgitate its next blood meal, passing on the infection. When the number of rats drops below a certain level the fleas move onto humans. This spreads the disease.
The Mongolians spread it into Europe by catapulting infected corpses into the besieged city of Caffa. From here it spread north into Europe, carried along trade routed by the ship-loving black rats.
Plague is now rarely heard of due to modern antibiotics but unfortunately rats still plague us by damaging our property. Put a stop to it with this new invention from Hammer Technologies.
