It was gruesome the most heard name in the Middle Ages because it changed the color of its victim’s skin. After its first recorded appearance in still it hung about 200 years, killed at least over one hundred million people or over. On all other continents, it still exists in a variety of wild animals. These animals are immune to the disease but there is no immun-ity to people. Decade 19 countries a total nearly 8,000 cases, of human plague. Eighty percent of most recent cases occur in Africa. Mainly caused by a bacterium, Yersinia Pestis. First appeared in America in 1899 arriving almost simultaneously at the parts of San Francisco, New York, and other places. The mysteries are why the disease seems to survive and prosper. Rodents would carry the disease across to the Americas the rat was immune to the disease making it a carrier for the disease. The colonies of rats infested the cities that were in America and made people die the next week or so meeting the rodent. A man named Boccaccio told many of a tale that he survived the plague he lived in England were the disease made the most im-pact and distraught. He made his money from fur from ox. Lit-tle did he know the ox fur was a good source of fleas and in-fected him making him sick within days? In the 1350s-fur cost thirty percent more than before its worth that would make him a wealthy man but the plague consumed his body. He would sleep and eat and drink and clean the …show more content…
In Septicemic plague, purple blotches appear when the bacteria damages blood vessels, resulting in bleeding under the skin. The blood flow is disrupted, tissue dies, fingers and toes form gangrene and must be amputated. Many died of boils and abscesses, and pustules on their shins or under their armpits; others just died. Symptoms would also include fever, chills, rapid coughing. Chest pains would make the victim useless without proper treatment, the disease can quickly lead to death. The disease has three stages Bubonic, septicemic and finally pneumonic. Along the body scattered bruises and nau-sea, vomiting, diarrhea and blood in urine, drops in blood pressure. Yellow fever is a viral disease and in the absence of an animal model. Scientist were unable to demonstrate that people with symptoms indeed. In 1992, Adrian Stobes and his colleagues successfully infected monkeys with yellow fever. The research behind that helped to try and find the cure for the bubonic plague creating a new hope for the future to do this they needed to test it on the monkeys before human tri-als. The monkeys have human genes and genomes that are closely relatable and the immunity map. They infected the monkeys with yellow fever and injected antibodies to fight off the infec-tion and it worked (walker 12). In Europe, they were trying to figure out how to reduce the painful enlarged lymph
