Some people experienced a swelling of the brain (McGill 1). Symptoms of bubonic plague include fever, chills, delirium, capillary hemorrhaging under the skin, and enlarged lymph nodes (“Plague” 1). People with the pneumonic strain can get the disease by coming in contact with animals or other people who are already infected (“Plague” 1). Pneumonic plague can develop as a complication of the bubonic strain (“Plague” 1). Hemorrhages turn black, hence the name Black Death (“Plague” 1).
Strep Throat is an infectious bacterial disease that is contagious and is caused by the inflammation and swelling in the lining of the mucus membranes in the back of the throat and the tonsils. The throat gets a burning sensation and a severe irritation, causing a sudden, severe sore throat. Strep throat generally affects the throat and tonsils and makes swallowing hard. Sometimes a sore throat is mistaken for strep throat. Sore throats are mostly caused by a viral infection and not the streptococcal bacteria.
In 1340 an infectious disease was spread by wild rats that carried bacteria. The reason why it was so deadly and gross was because the wild rats would carry Yersinia Pestis, which the fleas of the rats would bite into them and then bite into the humans. This was called The Black Death, also known as the Plague. The Black Death killed millions of people. The Black Death was one of europe 's most devastating widespreads in human history.
When the victim is bit by the flea the toxins drain to the nearest lymph node and swells to a tumor or a bubo. The average time to die with the bubonic strain of the plague is twenty-three days whereas the plague bacteria can break out into the bloodstream causing septicemic strain of Black Death (historytoday.com).The septicemic strain of Black Death is far worse than the bubonic plague it spreads the bubos to other parts of the body, the septicemic strain causing the pneumonic plague therefore this strain is the most dangerous. You could breathe the air of the infected and be dead within two days (The Black
Wright 5 Jayla WrightJared DiamondEnglish 428 February 2018 The Epidemic of SmallPox One of the most scariest diseases, if not the scariest disease, was smallpox. Smallpox was a game change in the 1500’s. The smallpox most definitely had one of the biggest impacts on the world. People often say that had it still been occurring it would have wiped out mankind and possibly all mammals, reptiles, amphibians and possibly most birds, and bugs. The cause of the civil war was because of an epidemic of smallpox.
The clinical signs and manifestations (e.g., fever, headache, nausea, and muscle aches) resemble many other diseases during the early stages when antibiotic treatment has more effect. A history of exposure to the appropriate vector tick, louse, flea, or mite is helpful but we cannot base our work upon it. Observation of a rash, which usually appears on or after day 3 of illness, should suggest the possibility of a rickettsial infection but, of course, may occur in many other diseases also. Knowledge of the geographic epidemiology of rickettsioses is useful, but is inconclusive for the individual patient. Except for epidemic louse-borne typhus, rickettsial diseases strike mostly as isolated single cases in any particular neighborhood.
This caused an awakening in the medical field, as physicians where viewed as a failure. “New medical tests were developed” and science began to make its way into medicine, as new concepts and health measures were beginning to develop (Swenson 185). The sight of death was in the eyes of every individual who witnessed this plague, and the unquestionable Catholic Church soon began to fall also. Peasants began to question their creators and turned away from religion for “having failed totally during the epidemic” (Swenson 185). The plague decimated nearly more than 50 percent of catholic clerics, paving the way for
On page 158, Preston writes, “Once the virus enters the cell, it becomes a Trojan horse”. Ebola is described as a very dangerous virus. The scientists try to find an end to this virus but know that it is unstoppable. Allusion is used when describing how Ebola invades the body. The Ebola virus enters the body and kills the host from the inside out.
During the mid-fourteenth century, a plague hit Europe. Initially spreading through rats and subsequently fleas, it killed at least one-third of the population of Europe and continued intermittently until the 18th century. There was no known cure at the time, and the bacteria spread very quickly and would kill an infected person within two days, which led to structural public policies, religious, and medical changes in Europe. The plague had an enormous social effect, killing much of the population and encouraging new health reforms, it also had religious effects by attracting the attention of the Catholic Church, and lastly, it affected the trade around Europe, limiting the transportation of goods. As a response to the plague that took place
Japanese encephalitis, West Nile, and yellow fever) to human (Mitchell 1995, Shroyer 1986). All these viruses are very harmful to human and other organisms, they causes several diseases to humans. For instance in 2007 there was an outbreak of chikungunya in Italy, and other cases of dengue viruses were reported in south France and Croatia. The dengue virus is known to have four strains, therefore attacking one strain doesn’t immunize against contracting the other strains, so it become so difficult to treat the diseases caused by this virus. Chikungunya virus causes fever, swelling and redness of joints, severe rheumatic pains and in some cases death; according to research in various lab it has been shown that when a person is repeatedly infected with dengue viruses, this increases the risk of more severe sickness such as DenguhocyndromSS which induces shock as a result of a sharp drop in the volume of blood which might also lead to
There are two different forms of pneumonic pest. The primary pneumonic plague infects people by droplet infection from human to human being. The secondary pneumonic plague develops out of a bubonic plague. The pathogens enter the lungs via blood vessels and provoke the septicaemic plague. The plague killed so many people
With the host’s immune response thus weakened, the bacilli quickly colonize the lymph nodes, producing a painful swelling and, eventually, destroying the tissue. On occasion they enter the bloodstream either directly or from the lymph nodes, bringing on a general septicemia, or blood poisoning. On postmortem examination they are found in great
The Black death was mainly caused by a deadly bacteria called Yersinia pestis. It spread by the river, spread by the trading, by the docks, and the Silk Road. The deadly effects of this disease were that buboes in the groin, armpits, neck, and elsewhere caused death to about ⅔ of Europe 's Population.
“Ebola Zaire (EBO-Z) killed two hundred and eighty of the three hundred and eighteen people infected Yambuku Mission Hospital (YMH) used the same needles with different patients. They did not dispose of them properly or sterilize the needles. EBO-Z was then spread throughout YMH, infecting staff members as well as patients” (Commission). This encounter shows how Ebola Zaire (EBO-Z) has been easily spread throughout the YMH and can ruin the human population. EBO-Z will eat its victim and lead them to a painful death.
If the disease travels to the heart it can cause blood vessels all over the body to leak and make basic functions of the body difficult to do. The Marburg Virus enters the cell and destroys it from the inside out replacing its RNA with negative RNA which kills the cell. The RNA of a cell carries the instructions from DNA to proteins. When affected, the cell can 't perform its basic functions correctly and harms itself. It primarily targets liver, lymphoid organs, which protect the body from infection, and kidneys.
