Why is the Cholera disease dangerous? Cholera is considered dangerous due to the fact that an individual can become severely dehydrated and the rapid loss of fluid that can occur over a short period of time. How does an individual get cholera? With further research into the mapping of the London Cholera Outbreak, John Snow mapped thirteen public wells in the Soho district and a To earn a nickname like this, innovative work must be achieved from such a man.

Doctor John Snow was a man who cautiously researched and came up with noteworthy insight on cholera. Cholera was said to be airborne during the mid 19th century and there were no successful treatments to help save the generous amount of people dying from dehydration. John Snow was born in Britain on March 15th, and became an apprentice to a surgeon at the age of fourteen years old BBC, In he graduated from the University of London and was a physician by the year Anderson, Doctor John Snow established himself in London as a physician, but was working on anaesthetics as well.

In another cholera outbreak had started and Doctor Snow was busier than At the time no one really knew what cholera was. All anyone was able to do was panic and make up theories. What they did know about cholera was just what they witnessed. Citizens would see their loved ones have severe cases of almost clear diarrhea with white specks, referred to as rice stool, and then die within days or even hours.

John Snow and Henry Whitehead came along to end the crisis using a different approach. They looked at the facts and collected evidence through interviews and surveys of the town. The most popular theory to how cholera spread amongst the population was the miasma theory.

The miasma theory was the idea that the disease was in the air. It was believed that people could get cholera by being exposed to the atmosphere in which the disease contaminated. The miasma theory has been around forever. The main cause of the progress made in public health provision in the years was only partly caused by the shocking impact of repeated epidemics of cholera. Source 16 suggests that the severe impact of cholera did cause progress made in public health.

Source 17 and 18 although do suggest that cholera did have an impact, progress however was made through other factors; dedicated individuals in Source 17 and scientific thinking in Source This suggests that the shocking impact of cholera did cause progress in public health. The cholera epidemic had a huge impact due to the 32, people who died.

This coupled with its speed to spread and strike people caused the government to bring in new legislations. This is shown when the Board of Health was set up to make sure local boards of health were set up to inspect food, clothing and overall hygiene of the poor.

However although many cities took advice on board and set up boards of health, knowledge into causes of cholera was still unknown so many measures tended to be a rather hit or miss affair. However since the government did take action shows they were willing to improve public health provision. John Snow was born into a labourer's family on 15 March in York and at 14 was apprenticed to a surgeon. In , he moved to London to start his formal medical education.

He became a member of the Royal College of Surgeons in , graduated from the University of London in and was admitted to the Royal College of Physicians in At the time, it was assumed that cholera was airborne. However, Snow did not accept this 'miasma' bad air theory, arguing that in fact entered the body through the mouth. He published his ideas in an essay 'On the Mode of Communication of Cholera ' in A few years later, Snow was able to prove his theory in dramatic circumstances.

In August , a cholera outbreak occurred in Soho. After careful investigation, including plotting cases of cholera on a map of the area, Snow was able to identify a water pump in Broad now Broadwick Street as the source of the disease. He had the handle of the pump removed, and cases of cholera immediately began to diminish. However, Snow's 'germ' theory of disease was not widely accepted until the s. Not only is he considered being a founding father of epidemiology, he was also a leading pioneer in the development of anesthesia, and developed the theory that cholera was communicated through a contaminated water supply.

The objective of my research is to identify the answers to three important questions. The methodology of this research paper will be obtained through secondary research. In , cholera cases were notified from 94 countries-the highest ever number of countries in one year WHO, Two disturbing aspects of global cholera picture in s have been-dramatic and unexpected reappearance of epidemic cholera caused by V.

Cholera is an infectious disease — caused by the bacterium vibrio cholera figure 1 — that affects the small intestine and causes a large amount of watery diarrhea. The bacteria conserves its energy and nutrients to pass through the acid in the stomach and then once inside the small intestine, propels itself into the mucus where it flourishes. Symptoms can show within a matter of. Valerie Montague Reading Response 6 Aberth He begins by describing the identification of cholera by Koch and some of the epidemiology.

Cholera is a gastrointestinal disease marked by excessive defecation and vomiting at alarming rates. This along with a toxin in the small intestines causes dehydration and wearing down of the GI tract. The first known pandemic of cholera began in and persisted in various parts of the world throughout the 19th century.

The disease presents an interesting. There is a lack of medical resources and treatment, so disease spreads quickly and impacts all areas of the country. To begin with, although cholera broke out only a few years ago, its impact has been widespread and debilitating. Background: Cholera is a dehydrating illness that affects millions of people worldwide. Although cholera vaccines can provide some protection against illness, the protective efficacy conferred by current vaccines are not equivalent to natural infection of Vibrio cholerae 1,2.

To combat cholera infection, the WHO has proposed a global initiative to reduce cholera deaths by 90 percent by In this call to action, the WHO designates the improvement and distribution of oral cholera vaccines as. This is the case since it has been considered as among the dangerous diseases currently, and which has been aligned with a variety of worldwide epidemics experienced in the near past. The disease sprang in , where it was first experienced in Indonesia, and spread to other nations around the globe.

According to WHO , in the 21st century, cholera was deemed to infect over Cholera is on the rise with an estimated 1. In many endemic countries, children under 5 account for more than half of the global incidence and deaths. Cholera has remained endemic in some Asian countries for centuries, has become endemic in an increasing number of African countries with epidemics throughout the years, and has recently returned to the Americas with.

While there are several strains of vibrio cholerae, only two types have been known to cause cholera outbreaks and only one type O1 is responsible for outbreaks globally WHO, Cholera infection is an acute diarrheal disease CDC, It is extremely virulent and can affect children and adults with equal severity if left untreated WHO, Vibrio cholerae has a short incubation.
