Bryan Abraham Abraham Grade 8 Science Mr. Loewen 3 February 2017 Period 2 Devils Fight Back MLA On the Australian island of Tasmania it is home top predator. The Tasmanian devil has been one of the top predators for more than a century in Tasmania but within the last 20 years they have been attacked by a disease, that is threatening their existence. This deadly disease they have been given is called Devil Facial Tumor disease (DFTD). The disease was first discovered in 1996 and spread very quickly, the disease caused lumps on the devils face or neck making it not able to breathe or eat so it was almost always fatal. Scientist
It reached Europe in 1347. In a few years up to 50 percent of the population died, with higher mortality rates in urban areas. It returned every few years for centuries.
It started in central Asia, 1338 awakened by a drought, slowly makings its way to Europe. It finally hit Europe in 1345, 8 years later from the awakening, it first affected Crimea when a trade was being done with the merchant's Italian sailors and Mongolian's but it got out of hand until the point where the Italians were held up in a castle with nowhere to run for a year. The Mongolians soldier finally backed off but when their men starting dropping dead they had the idea to throw the infected dead bodies over the castle wall and into the castle, it was the first bioweapon created. Some of the Italian sailors managed to get away but they ended up carrying the mysterious death with going from town to town but no one would let them stop as infected rats had hidden within the cargo. But it was too late, in 1347, Sicily, the sailors docked but they were forced to move on, the brief encounter, however, allowed the infected rats to climb ashore and start spreading the disease. Soon it spread throughout trade routes such as the silk trade route which
The victims of this plague suffered from delusions, nightmares, fevers and swellings in the groin, armpits and behind their ears. Some of the sufferers went into comas while others reported being highly delusional. At the time period this was going on there wasn't any medicine that they have tried to cure this plague. This plague ended up being contained in 750 CE it took 208 years for this plague to pass because they couldn't find a cure for it because they didn't have a strong medical field this plague spread exponentially. They couldn't find a way to actually cure this disease because it was combined with the Black Death so they were killing all their skilled doctors before they could even begin to start on a cure for this disease. One historian by the name of Procopius has reported that 10,000 people per day have been
The Irish discovered the problem when they found that they were harvesting black potatoes. At first they blamed the problem on poor weather, or insects. They just figured that it was another poor farming season. The actual spreading of the disease was that its pores were carried in the wind and land in pits where potatoes were to be planted. The disease would not die in the extreme winter cold and would double the problem for the next spring’s crop.
According to the book ¨An American Plague¨, At first no one realized that there was a sickness going around because it started on one street that was more of a street. They first doctor to notice this sickness was Dr.Hugh Hodge. He was a very respected doctor and he decided that the sickness was thought to be forgotten a plague called the yellow fever. The people were terrified when it was announced to the public, because there was no cure. The last time a civilization dealt with this fever it nearly killed 50% of their population.
was what made it especially dangerous, there was no known way to control the disease and it was able
Many symptoms could come of this illness that caused mass scrutiny all around. Document 1 states that Gavoccioli were swellings that varied in size but spread quickly. After these spread through the body a plethora of dark distinct spots appeared on the skin (Document 1). There was no cure or vaccination at this point in time, merely demise. No man knew why it could not be cured but many wondered if it was the ignorance of physicians or nature not allowing for a cure (Document
When the plague first infected a person, it began with swellings in the groin and armpit (Document 2). Some of the swellings could be the size of an apple or an egg (ibid.)! After the first swellings appeared, the whole body would soon be covered in dark and bluish grey spots (ibid.). Soon after these spots covered the body, death would be upon the infected person within days (ibid.). Many doctors tried to cure people of these symptoms, but many failed (ibid.) This was because of the nature of the illness or the ignorance of the doctors’ (ibid.). The doctors didn’t know enough about the disease to be able to effectively treat their patients’
It was a type of plague that was spread via the bite of infected rat fleas. The initial cause of the plague was diseased rats, with the bacteria Yersinia pestis, in their bloodstream as seen in source 1. Fleas lived on rats and when a flea bit the infected rat, the bacteria would enter the fleas stomach and multiply as seen in source 1. Due to the sudden decrease in the rat population (from disease), many fleas needed a better source of food, so they jumped onto people and bit them. This in turn is how people caught the plague. In the 1320’s a great famine broke out in china, and this caused many rats to die, also resulting in the quick spread of the plague. The name black death came from the swollen buboes (glands) in the victim’s neck, arm pit, and inner thigh that turned black as they filled with blood. Victims often died within 12 hours to 7 days of being bitten. Due to lack of hygiene and living in close, dirty and crowded proximity, rats were very common, making the disease easily contagious. The black death was a combination of three different streams of plague – bubonic, pneumonic and septicaemic. The bubonic plague was the most common form of the plague and was caused by infected fleas biting people. As seen in source 2, sufferers would have large lumps covering their body, as well as have a fever or headache. Soon after the victim would have slurred speech and vomit blood. Pneumonic was deadly
In the early 1330s, an outbreak of deadly bubonic plague occurred in Europe. The bubonic plague mainly affected rodents, but fleas were also able to transmit the disease to people. Once people were infected, they quickly infected others, which meant the disease spread very rapidly among the population. The plague caused fever and a painful swelling of the lymph glands called buboes. The disease also caused spots on the skin that started out red and eventually turned black, which is where “The Black Death” got its name. (The Black Death: Bubonic Plague) During the 14th century, there seemed to be no rational explanation for what was happening. No one knew exactly how the Black Death was transmitted from one patient to another and no one knew
The Plague that struck Europe and Asia in the 14th century was probably the most devastating disease or natural disaster the world ever faced. The Bubonic Plague or Black Death killed an estimated 25 million people from 1347 to 1352 in Europe which accounted for one third of Europe’s population.??-1 It is believed to have started in Asia and then spread to Europe. The Bubonic Plague was not just limited to this period in time. It would reappear through the centuries including the Great Plague of London around 1656 in which 20% of London residents died from it.??-2 Although some of the latter breakouts of the plague were also catastrophic, this paper will primarily focus on the plague from the 1300s. More specifically, this paper will
During 1348- 1349, a devastating sickness swept over all of Western Europe that wiped out about half of the population. The Black Death, also known as The Plague and the Bubonic Plague, killed thousands over the span of two summers. The Black Death was caused by the bacteria Y. Pestis, which normally lives dormant in a flea's stomach. However, when a flea bites a rat, the rat becomes infected, which eventually leads to a human being infected. Since rats had a high abundance in 1348-1349, the disease was very easily spread to humans, where it then became airborne (pneumonic), bubonic, or spread throughout the blood, also known as systemic. (The Black Death).
Rabies had been known about since 2000 B.C. but technology was obviously not advanced enough to try and do anything about the spread of the virus. In the year 1885, France and Belgium had become plagued with more and more cases of the rabies that the fear had soon began to become a very reasonable fear for people to have. This gave Louis Pasteur ample reason to research more about the virus.
The Bubonic Plague and a variation called the septicemic plague was spread throughout Europe by oriental rats that carried infected fleas. Little is known to why the infection never seemed to affect the carrier rats. Infected fleas were being starved by the infection, so they began feasting upon the people they came into contact with. These fleas coming into contact with any human being would infect the human with the disease. These people were now carriers of the Bubonic plague or Black Death. These infected people would then spread the disease by coughing or coming into direct contact with another human being. However, this disease, since not being transmitted via rat would now be called the Pneumonic Plague. (www.insecta-inspecta.com).
The fastest communication of the virus to humans were reported in turkey. Simultaneously, 1.5 million birds were killed to contain the virus. The symptoms of such a disease that the temperature of your body dramatically starts to increase followed by a cough. Then the host (humans) starts to experience a difficulty in breathing and a severe pain in the stomach most of it ends with diarrhea – a disease happens when our digestive system are not able any more to absorb liquids and minerals. A further exposure to the virus can lead to shock, the respiratory system stop working completely, and the other vital organs like liver fail to function normally and eventually death may occur.
