Detailed explanation-1: -The disease spread through flea bites. But the fleas hitched a ride out of Central Asia on the backs of both traders and camels traveling with trade caravans. From these hosts, the fleas spread to rodents traveling with the caravans and to rats that infested trading ships.
Detailed explanation-2: -Black rats were the most common at this time, and carried the bacteria called Yersinia pestis, which caused the plague. The rats then spread it to fleas that lived on their bodies. The fleas would drink the blood of infected rats, swallowing harmful bacteria. They then passed the infection onto humans by biting them.
Detailed explanation-3: -The disease probably rode on its animal hosts and approached key maritime trade ports or inland trade ports by ship.
Detailed explanation-4: -Scientists now believe the plague spread too fast for rats to be the culprits. Rats have long been blamed for spreading the Black Death around Europe in the 14th century.
