Ring around the Rosie’s: The power of the Black Death Emily Shelton HIS 103: World Civilizations I November 19, 2011 Ring around the Rosie’s: The power of the Black Death The Black Death, swept through Western Europe in early spring of 1348. The disease had already swept through the east, and now was making way through Europe. The disease was from the bacterium known as Yersinia pestis (Wade, 2010). There are three different forms of the disease, but the most common is the bubonic plague form. This transmitted from fleas that are on the infected rat, which then bites the human giving them the disease as well.
2. When the infected mosquitoes bite people, they can pass the virus onto humans. The virus is spread throughout majority of the globe putting all at risk of acquiring the disease. You may be wondering what the symptoms are and what the virus can do once it gets inside your
SZT Task # 3 Measles The measles, also known as rubeola, is a viral disease that affects the respiratory system. Measles is caused by the paramyxovirus family. The virus grows in the cells that line the back of the throat. (WHO) The measles disease is highly contagious and is transmitted by respiration either by indirect contact such as aerosol exposure or direct contact such as exposure to fluid in an infected person’s mouth and nose. (Wikipedia contributors) The virus also remains alive and contagious on exposed surfaces and in the air for up two hours.
a prostrating biphasic illness begins. 2 to 3 days after initial infection, symptoms of fever, malaise, body aches, headache, anorexia, nausea and vomiting begin followed by red spots in the mouth and on the tongue. Patients are most infectious during this period. Twenty-four hours later, the skin rash appears, beginning with flat red spots on the face and neck which spread quickly to other parts of the body. The skin rash evolves uniformly in all areas.
Author: Jake Date: 12/09/2010 Introduction This essay includes my findings from research on the disease, and explains the signs, symptoms, causes, cures and prevention of the pathogen Cholera. The Bacterium Cholera is a severe bacterial infection caused by the bacterium “Vibrio cholerae”, the most common symptoms of the infection are diarrhoea ,vomiting and muscle cramps, this can lead to rapid dehydration and sometimes death. You can transmit Cholera by water that is contaminated with infected faeces; and also transmit it due to poor food hygiene1. Cholera kills an estimated 120,000 people a year2. If the bacteria enter the small intestine, they use their flagella to propel themselves through the lining of the intestinal wall, they produce a toxic protein.
about 500 to 1,500 happen in the us every year. this disease has two types; type I is caused by anaerobic bacteria with or without the presence aerobic bacteria, type II also called hemolytic streptococcal gangrene is caused by group A streptococci, other bacteria may or may not be present the disease may be also be called synergistic gangrene.Muscle and fat tissue are affected as a consequence of infection. Necrotizing fasciitis is a severe complication of group A streptococcal infection. The bacteria cause the destruction of skin and muscle by releasing toxins. Additional complications can occur from necrotizing fasciitis, such as shock and organ
At some point in the summer of 1793 a mosquito bit an infected refugee, then later bit a Philadelphian, starting the deadly epidemic known as Yellow Fever. Yellow Fever originated in the jungles of South America and Sub Saharan Africa. This deadly disease is spread by two types of mosquitoes, the Aedes Agypti and the Yellow Fever Epidemic of
The plague bacilli are little toxin factories. The heat of the human body signals the thousands of bacilli injected by the flea to go into a special production. If the immune system manages to kill some, the germs release more poisons from their dying bodies. Meanwhile, they work their way into the fluid drainage system to travel. If the flea bite was on the leg, the lymph drainpipes carry plague to the lymph nodes in the groin.
  James L. Myers Professor Fike World Civilizations 22 July 2012 The Black Death: The Bubonic Plaque of 1300-1400. The Bubonic Plaque, also known as the Black Death has had a profound effect on human history since the ancient times. The Black Death is a highly contagious disease that causes death within one to three days of contracting it, depending on which type a person has. It can be air born or can spread to humans through fleas that have bitten black rats that are infected with the Bubonic Plaque. When a human comes in contact with the fleas and rats that are infected and are bitten by these infected animals, they also become infected.
After the research was no more need of use, McCoy evacuated the Hygienic Laboratory and began to kill the experiment animals. This would contain and prevent another disastrous outbreak. A few months later when everything is contained congress grants the Hygienic Laboratory with a new name, The National Institute of Health. This epidemic brought disease and catastrophe. Parrot Fever spread throughout America, and eventually brought death to one of five people that were infected.” There were a total of a hundred and sixty-nine cases of psittacosis nationwide.
