Cholera Is An Infectious Bacterial Disease Of The Small Intestine Essay

1. The Europeans poured have poured something into the water which sterilized the water and killed the toxins that become disruptive in the digestive system when they are consumed. They Europeans may have poured what are called oral rehydration salts into the well, which quickly works are combatting the cholera, and will prevent further outbreaks from occurring.

The work of these two men changed the contemporary views on how disease was spread. By solving the cholera mystery, they helped contribute to making the world safe for bigger cities. Over the next few years a lot of changes were made. Both the medical and public health establishments latched onto Snow’s waterborne theory and through one of the greatest feats in engineering history, London started the process of making an entirely new sewer system. This, along with other precautions such as boiling water that was suspected to be contaminated, brought an end to city-wide choleric outbreaks. Besides the improvements in sewage, the improvements of sanitary conditions all around greatly diminished the spread of disease and held a major part in making the modern city possible. Overall, it turned out that something that was once horrendous and deadly for a massive amount of people, eventually turned out to be helpful for the future of mankind. (Johnson)

6. Why would evidence of cholera in people living side by side, differing only in water supply, provide critical evidence?

John Snow born on the 15th March 1813 – 16th June 1858 grew up in the poorest region of York and subsequently specialised his life establishing the link between the cholera infection he had first encountered in 1831 in Newcastle and water as its vector. Snow’s most famous attribute was his research relating to the cholera outbreak in the London Epidemic of 1854. ‘On proceeding to the spot, I found that nearly all the deaths had taken place within a short distance of the [Broad Street] pump. There were only ten deaths in houses situated decidedly nearer to another street-pump. In five of these cases the families of the deceased persons informed me that they always sent to the pump in Broad Street, as they preferred the water to

Some of the most emerging and re-emerging agents of the waterborne diseases are; Cholera which is caused by the ingestion of water that is infected by Vibrio Cholerae. This is a painless form of diarrhea characterized by watery stool. Dysentery which is caused by Escherichia Coli. Typhoid that is caused by Salmonella typhi which is usually accompanied by fever is yet another disease. Gastroenteritis diseases caused by Giardia and Cryptosporodia and some species of hepatitis are also known to be caused by water (CDC, 2011). These disease causing agents find their way into the human body through infected water that people from the poorer communities in Uganda use and have no option of cleaner water.

Causes: Cholera is caused by the bacterium Vibrio cholerae. The bacteria releases a toxin that causes increased release of water from cells in the intestines, which produces severe

In the very first chapter, Steven Johnson begins to set the scene of how the overpopulation of London coupled with extreme levels of poverty created the perfect opportunity for Cholera to spread in the rapid manner that it did. On page one it states; “These were the London underclasses, at least a hundred thousand strong. So immense were their numbers that had the scavengers broken off and formed their own city, it would have been the fifth-largest in all of England.” Johnson mentions that the city of London had become a city of Scavengers, consisting of; bone-pickers, pure-finders, dredgermen, sewer-hunters and night-soil men. However, the harshest reflection of the Cholera epidemic of 1854 is conveyed by John Snow himself. On page 59 it states; “The young Snow observed

He linked the common illness cholera to people whom drank from the wells. He observed those getting ill and which areas and pumps they drank from and recorded it on a map, he was then able to establish all those getting ill were in fact drinking from the same pump, and consequently in 1854 John Snow removed the handle of the Broad Street pump and ceased the epidemic of Cholera in Soho, London

Dr. John Snow was known as an intelligent physician who had a background with anesthesia advancements. He believed that cholera was a waterborne disease and that it was contaminated by the sewage. Snow’s goal was to convince others about the issue and stop it from spreading. His theory about the intestinal disease, in which was published in 1849 in an article, was laughed at and many doctors believed that his idea was “wrong” and they continued to believe that it was airborne. He wanted to prove many wrong and begin to further research and experiment the disease.

Between the 1830’s to 1860’s, cholera spread into the United States from India by trade routes. Cholera is an acute diarrhoeal infection caused by drinking or eating material that is infected with Vibrio cholerae. Cholera causes watery diarrhoea, but can show days later or never show

Although most disease struck the poorest, the upper class was not fully immune. Because people wanted to move to cities to make their lives better, they were forced to live around these diseases without proper means for prevention, protection, and recovery. Once contracting the disease, they would either die within hours or suffer from uncontrollable diarrhea and pain. In addition, scientific knowledge on disease was not as developed as it fortunately is today. Doctors had not yet learned the concept of a germ theory and instead associated the disease with the “bad air” that surrounded toxic, polluted cities. This “bad air” was known as miasa and was incorrectly used to explain the spread of cholera in major cities during the mid 1800s. After studies and research, doctors noticed that there was a heavy concentration of miasmata near certain rivers, but they still connected it to a lack of air quality in bustling cities such as Manchester, London, and Paris. Although air pollution and coal emissions did play a role in certain illnesses, they were not the main cause for diseases such as cholera. Poor ventilation, dirty homes, malnourishment, and no access to clean water made people easily susceptible to a ruthless disease like cholera. Moreover, causes of cholera were investigated more thoroughly after John Snow’s theory claimed that cholera was spread through the water John Snow was an English physician who is today considered one of the fathers of modern epidemiology, the branch of medicine that deals with the distribution and control of diseases relating to health. Finally, doctors could see cholera in a new light and were able to find better means of protection and prevention for its victims. Today, doctors recognize the germ theory of disease which states that some diseases are caused by microorganisms, and not just by “bad

The hygiene movement helped in the avoidance of communicable diseases, diseases for example cholera, tuberculosis and water illnesses in large part by modifying the people surroundings. In the 1850s, John Snow assisted in recognized the importance in data collection and documentation. His actions terminated an outbreak of cholera in a district of London. Using the same methodology Ignaz Semmelweis, applied it to restraint fever of childbirth a major source of maternal mortality. The reason that this was happening was that after physicians worked on the death bodies, usually they did not wash their and delivered babies and contaminating both, the mother and the baby.

Almost 100 countries worldwide are still affected by cholera and it’s virtually impossible to completely prevent an outbreak. If left alone, this rapidly infectious disease can cause many fatalities. However, improved methods for surveillance, diagnosis, and treatment, paired with higher standards of sanitation and personal

The disease, cholera, is an infection of the intestines, caused by the bacterium Vibrio cholerae. As stated in Microbes and Infections of the Gut, the bacterium is “a Gram-negative, comma- shaped, highly motile organism with a single terminal flagellum” (105). Cholera is characterized by the most significant symptom that presents with the disease, diarrhea, and victims can lose up to twenty liters of body fluids in a day. Cholera can be a serious disease, due to the serious dehydration that can occur, but it is only fatal if treatment is not administered as soon as possible. This research paper includes information on the causes of cholera, symptoms, ways of treatment, studies of treatments, complications that may occur, the

Throughout history until the 19th century, infectious diseases, epidemics, and pandemics were thought to be the manifestation of supernatural forces and little to nothing was truly effective in preventing or treating these devastating threats to society. It was only during the Age of Reason and the Enlightenment that the long-accepted realities of society were questioned and research was conducted based on science and reason that would forever change the world we live in (Kumar, 2007). The science of epidemiology was founded by John Snow’s identification of polluted public water well as the source of an 1854 cholera outbreak in London. Shortly thereafter germ theory began to emerge and science took off.
