fleas can transmit plaque because they can handle it they can not carry aids due to not only their sizes because of how there orgasms work as well they pressure it would put on the body.
Fleas carried the plague because they carried bacterium through their bites and the bacterium carried the plague, and rats did not get it because the fleas landed on rats and then jumped to other animals and possibly humans.
Because animals had fleas which carried the disease and once the animals died the fleas jumped onto more animals which carried to disease to different places.
The black death began to spread in about 1437 during the Middle Ages from fleas that bit mice and rats that were infected with a the black death. The fleas would swell from the infected blood they took in and vomit it out. Fleas love to bite humans bite humans any chance they get. Infected fleas bit any human they could find spreading the black death.
Plague is a disease that is spread by the fleas of infected rats. If you can kill all the rats, you can slow down the spread of plague. Unfortunately, the highly superstitious people of the middle ages associated cats with witchcraft with the devil, so many towns killed all their cats - which allowed rats to take over, and the plague came with them. So if you don't have plague, leave town and live in a cottage with lots of cats. You'll be safe from plague. Until the villagers come to burn down your house, because of all the cats.....
Flea bites and suck up the blood of a rat and the rats infect the fleas, then the rats die and the fleas go to find a different host ( the human ) and then the flea bites them but can't hold anymore blood so they spit the infected diseased blood back into the human making the human infected with the black plague/ Bubonic Plague
London was a major port at the time of the Great Plague of 1665. Rats would come off of the ships visiting London and those rats carried fleas which started the Plague. The Great Fire of London the following year, killed all the rats and put an end to the Plague.
The black plague (bubonic and pneumonic plague) never went away. There are periodic outbreaks in many areas of the world. However, the plague is a bacteria which generally responds well to antibiotics, and modern sanitation has extensively reduced the vermin that are the primary carriers and the fleas that are the primary means of transmission, so that outbreaks usually affect no more than a handful of people.
what caused the black death was rats from china cause when people from china would come over to Europe to deliver things they have made for the europeans and the rats came on the ship with these fleas on them and the fleas carried the bubonic plague witch got into the rats so when the people from china came over with this disease all the rats came out of the ship and the Chinese people died on the ship with the disease it caused the bubonic plague to happen witch it did so that's what happened.
can fleas climb up drains
rats, mostly black rats and rodents. the fleas came on them and then sucked there blood then go to humans and spread the plagueto others and the plague is very contagious so it spread and thats where the black plague came from! hope that answered your question:D :)
Cat scratch fever is caused by a bacteria that is generally transmitted to the cat by fleas. If the cat isn't carrying the disease, then they will be unable to transmit it to you, the human.
No. Bubonic plague is transmitted by fleas carried by infected rats or people. The pathogen is typically carried by rodents. In the case of the waves of plague that ravaged Europe and the Mid-East in the middle ages, it was carried by rats and other infected humans.The disease you may be confusing bubonic plague with could be cholera which is transmitted by contamination of water by an infected person's feces.Answer:No, it was caused by rats, but not their excrete. the bubonic plague and pneumonic plague were started by rats who jumped off a ship that had come from countries infected with the plague. It wasn't actually the rats that started it, either. fleas travelled in the dirty hairs of the rats and then flourished in the grime and unhygienic areas near London. The plague spread quickly throughout England and Ireland, and only a small part of Scotland was not affected. 1 in 3 people died, altogether. Many towns and villages were quarantined to stop the plague spreading.
