How did the Black Plague speared?

Answer 1

Rats and fleas. The fleas caught the disease and it blocked their feeding tube, which caused them to bite everything in order to feed more. This spread the disease. the rats also died of the disease, but only after they had spread it around. The way a town could tell the black plague was coming was they would find dead rats all over the place, and they new the humans were next. The actual bubonic disease was combined with an infleuenza virus to make it airborne, and that helped it travel much easier. The bubonic plagues that followed did not have this combination, and did not produce as many deaths.

Answer 2

Spread.

The Black plague is a form of bubonic plague.

Plague is primarily a disease of rodents. Infection most often occurs when a person is bitten by a rat or flea that has fed on an infected rodent. The bacteria multiply inside the flea, sticking together to form a plug that blocks its stomach and causes it to become very hungry. The flea then voraciously bites a host and continues to feed, even though it is unable to satisfy its hunger. During the feeding process, blood cannot flow into the blocked stomach, and consequently the flea vomits blood tainted with the bacteria back into the bite wound. The Bubonic plague bacterium then infects a new host, and the flea eventually dies from starvation. Any serious outbreak of plague is usually started by other disease outbreaks in rodents, or some other crash in the rodent population. During these outbreaks, infected fleas that have lost their normal hosts seek other sources of blood.

Alright, I'm glad you asked this question cuz I'm taking a final on this tomorrow. The plague was originally with the mongols, and when they attacked the PORT city of Caffa they flung the bodies of their dead into the city (biological warfare) into the city infecting everyone inside. From there a group of Genoean sailors escaped to Messina with the plague allowing it to migrate. From there it was passed along to fleas and rats who infested every little space. Hope it helps.

Answer 4

It began in China. Ships carried infected rats carrying fleas to Italy. The sailors onboard were infected and not allowed off the ship but the rats...well.....that was a differnt story. For ages it was never know how the disease was transmitted. Hence the constant reoccurences.

Answer 5

It came from rats and fleas...how it spread...hmmm.......its because the rats came on board ships, renaissance (I think),and infected the passengers in the ships. Then the passengers went to town and traded with other people creating a chain, and those people infected other people too. I'm not sure about that, but check somewhere else. I could be very very wrong.

Answer 6

I didn't know you could spear some one with the Black Plague. When did they do that?

Answer 7

Yersinia pestis bacteria spread by fleas on rats.

"Bubonic and septicaemic plague are transmitted by direct contact with fleas."

Answer 8

I don't know how it 'speared', but the most cited way that it 'spread' was from rat bites and arthropod vectors, such as fleas or ticks.

Answer 9

diseased rats with a species of fleas that got spread when they got shipped by boat to europe

Answer 10

Fleas on rats on boats.
