What was the black death plague?
The influenza (spanish flu) virus killed a simliar amount of people after World War I, but far fewer as a proportion of the population. The Black Death was the worst biological plague in the history of mankind.
What did people think in the middle ages caused the plague?
Doctors thought the black death was a plague, the virus, unsure. But the virus started as a lump about the size of a baseball on the arm or leg. Then the lumps would spread, and turn an Erie yellow color. Death would all ways arrive in the next five days max.
Was the Black Death a parasite or bacteria or a virus?
We don't actually know what the Black Death was exactly. The most accepted theory is that it was a form of Bubonic Plague, caused by a bacteria called Yersinia Pestis which was spread through the bites of fleas. This theory makes sense, because the bacteria is native to Asia, where the plague started. Black Rats from Asia managed to get into Europe on ships during trades, spreading the bacteria and therefore the plague into Europe. Another theory, less popular that the one above, is that the plague was actually caused by an Ebola Virus. The virus's incubation period is longer than that of the Yersinia Pestis bacteria, which is believed to contributed to the Black Death spreading so quickly, because the virus survived longer in the hosts before becoming lethal. However, the theory would also explain how the plague travelled from human to human, as Ebola Viruses are passed on through human contact, whereas it is extremely rare for Yersinia Pestis to be passed on through human contact. One of the most recent theories is Anthrax, which is a bacterial disease from cattle products. This theory is actually gaining popularity due to recent evidences. Indeed, cattle was transported from Asia, where plague originated, to Europe in trades. A recent archaeological investigation into a plague pit discovered in Scotland (where dead bodies of plague victims were thrown in and buried), biological archaeologists discovered signs of anthrax spores. Doctors, pathologists and physicians notes written during the Black Plague period reported symptoms of "boils, blisters, lesions, ulcers, Eschar ulcers, toxidemia, flu, vomiting blood and intestine inflammation". All of these are symptoms of Anthrax. If it was indeed Anthrax, then the flu-like symptom would have helped the Anthrax bacteria spread through sneezes and coughs. It has also been suggested that the Black Death was caused by a mixture of both Bubonic and Anthrax. So there you have your theories. The bubonic theory is the most widely accepted, but it does not explain how the Black Death managed to spread so fast and so far. The Ebola theory is able to explain how the Black Death spread so far and so fast and also how it was passed on by human contact. However the symptoms do not match medical notes from the Black Plague period, so the theory is not very popular. The Anthrax theory is not currently as popular as the bubonic theory, but is more popular than the Ebola theory. However it is rapidly gaining popularity as more and more evidence of the similarities between the symptoms of the Black Death and Anthrax are discovered as well as the discovery of Anthrax spores at archaeological dig sites.
What are the differences between the Black Death and the Great Plague?
Bubonic Plague or Black Plague started in Europe around 1347. It was a terrible disease that was carried out with black rats and fleas. This terrible disease was affected the Medieval society. It was a terrible because so many peasants died and that nobody was left to farm the land and do the daily work.The Plague (or called "Black Death") was an epidemic that struck Europe. People from China and Mongolia came with infected fleas carried by rats going aboard ships and that were transported to Italy, Greece and France; when the ships docked, the rats left the ships entering cities bringing the fleas and disease with them. In 1348 the virus, known as the Yersinia pestisbacterium and until 1351 the bacterium had killed 1/3 of Europe. Leaving fewer farmers and other people that held jobs that were important to the economy. The Europeans blamed the Jews for the plague by poisoning the water but it really was caused by flea bites. Other break outs occurred between 1451-1721.Plague is still around today in small numbers and is treated with antibiotics.
What were the symptoms of the plague in 1665?
There were outbreaks of Plague throughout the Middle Ages, due to the unsanitary conditions of the time. It was borne by fleas which spread via the rats. Rats were often aboard ships of cargo to other countries, and the plague spread to other countries via the rats. In the case of the 1665 plague, this particular outbreak originated in Holland. King Charles II had already stopped trade with Holland in 1663 in order to minimise the chance of it spreading to England, but, within two years, the plague arrived on the streets of the poorer areas of London. The Great Fire of London which occurred in 1666 was a blessing in disguise. It wiped out the rats, the fleas and hence, the disease.

How does black plague compare to other diseases?
The black plague was carried by the fleas of infected rodents. In most of the countries today, this type of transmission is rare. The plague also killed two-thirds of its victims within four days, which is similar to the Ebola virus.

What kind of sickness is the black plague?
Answer:The Bubonic plague (Black Death) developed in the middle ages. it was said to be passed on by fleas to rats on merchant ships. The rats then passed it on to the people on the ships who easily transferred it to anyone they came in contact with. All they had to do was breathe on them. The plague made areas of the human body turn black and/or purple, and about 6 million people died from it
