The Bubonic Plague killed nearly 80 to 90 percent of the population killing 1 out of every 3 people. the cause of the plague were fleas which were carried by rats which lived on boats. The people didn't know what was causing the plague at the time and thought it was a message from God. Hope this helps!
The 'black death' is usually referenced to the bubonic plague in which fleas from rats infected many humans causing them severe sickness and resulted in death. The mortality rate for those infected with the bubonic plague was 30-75 percent.
The Bubonic Plague (also known as the Black Plague) caused death throughout Enlgand around the time of 932 A.D.
The black death was a specific outbreak of diseases caused by the bacterium Yersinia pestis, in 1347 to about 1352 in Europe. Historically, there has been some question about this, with some scholars suggesting different organisms being the cause, but modern forensics seem to support Yersinia pestis as the cause.There are three manifestation of disease, referred to as the bubonic plague, the septicemic plague, and the pneumonic plague. Most usually, the disease is bubonic, referring to the buboes or very swollen lymph nodes present. If the disease gets into the blood system, it becomes septicemic, and is very much more likely to be fatal. The pneumonic manifestation happens when the disease gets into the lungs, and in this form it can be spread by the droplets a person coughs up into the air, with the new victims getting it first in the lungs.There is a link below.
During the bubonic plague outbreak in Europe, erroneous practices included the widespread use of quarantine, which often isolated healthy individuals alongside the sick, leading to further transmission. Additionally, some communities resorted to scapegoating marginalized groups, such as Jews, blaming them for the plague and subjecting them to violence and persecution. Other misguided efforts included the use of ineffective remedies and the belief that "miasmas" or bad air were the primary cause, diverting attention from better hygiene and public health measures.
The black death all started cause the European people didn't take care of there trash properly. This caused rats... Rats had fleas.. And the rats got affected with the disease this is a good 7th grade answer
The rats and fleas carried the black death ** Correction... Rat fleas carried the Bubonic Plague. There is still speculation as to whether the black death was actually bubonic plague as there are very many differences between the pandemics. One theory is that the black death was actually Ebola.
During the time of the bubonic plague, various ineffective cures were attempted, such as bloodletting, herbal remedies, and wearing protective charms. These methods were based on the miasma theory of disease, which believed that illnesses were caused by "bad air." However, the true cause of the bubonic plague, Yersinia pestis bacteria, was not understood at the time, leading to ineffective treatments. The development of antibiotics in the 20th century revolutionized the treatment of the bubonic plague, making it a highly treatable disease today.
Bubonic and septicemic plague are two of the three types of plague. The main difference between the two is that the bubonic plague cause extreme infection and swelling of the lymph nodes while the septicemic plague cause the body's clotting mechanism to stop.
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.
The speed that Bubonic Plague overtook its victims and the gruesomeness of the death were particularly frightening, especially when the cause was unknown.
Australia has had the bubonic plague. The bubonic plague first hit Australia in January 1900 and continued through to July, when a major cleansing operation was conducted in Sydney. However, ships coming from overseas continued to cause more outbreaks of the plague in Australia right through to 1925. During this time, there were 1371 cases of plague reported, and 535 deaths.
The bacteria that is believed to be the main cause of Black Death (bubonic plague, pneumonic plague and septicemic) is yersinia pestis.
They are different names for the same thing.
Ships were transported back from China which were carrying black rats (Infected Rats) and the fleas that lived on them sucked their blood and then sucked humans blood, therefore giving us the infected blood, therefore giving us the bubonic plague.
Tthe bubonic plague - which killed a lot of people and that there was no cure for.
"The plague" doesn't mean too much as many diseases and even animals - like locusts - have been said to cause plagues. But - There is debate as to what the famous "black death" was as the normal form of bubonic plague, which is what it has traditionally been associated with, does not normally behave as the disease did during that time. Yersinia pestis is the bacillus that causes plague.
