How Was The Plague Spread By Rats?

The plague is a deadly disease caused by the Yersinia pestis bacteria carried in fleas on the back of black rats.  In the fourteenth century more than a third of the population of Europe was wiped out by an epidemic.  The death rate is 100% without antibiotics, which didn't exist in those times.

But how did it happen?

The disease originated in the dry flat-lands of Central Asia where it traveled along the Silk Road to Europe on rats.  It entered Caffa when besieging Mongols hurled their dead over the walls in order to infect the Caffans.  The inhabitants fled, taking the disease North with them spreading it further into Europe.

Nowadays the plague is thankfully rare.  It is, however, common for rats to chew the wires on expensive cars, computers and industrial machinery.  Their teeth grow continuously throughout their lives and need to be constantly worn down.  The boffins over at Hammer Technologies have been toiling away to stop this happening. They have come up with a new type of flooring which will put paid to those naughty rodents once and for all.  It uses brand-new patent-pending technology to keep the rats away. It keeps your belongings safe from those sharp little teeth.
