rats to fleas, fleas to humans, then human to human
Black Death was a Plague. Humans, animal especially rats could get infected.
the Black Death killed animals and birds as well as humans.
The black death was carried by the oriental rat flea which then was past onto the rats then humans
The wild black rat was the main carrier, but the Plague could be passed from an infected person to healthy one as well.
The same as humans.
Fleas infested with a parasite passed it on to humans.
People caught Black Death by the fleas transferring the virus to humans.
you could get it anytime and any place
I believe rats was the first to carry the black death, they were called the black rats and the plague was spread to humans, that's what i was told in my history lesson:)
The two theories are: Tiny fleas would bite the rats that infested the streets. They would then carry bacteria from the rat to humans, because they would bite humans, spreading the bacteria. Humans would then spread the disease by touching and being near other people. The other theory is that God was punishing all humans for their sins by sending the Bubonic Plague (Black Death)
Rats to fleas, fleas to humans
Fleas transmitted the disease from rats to humans.
