- But if you’re going to talk about the history of epidemiology, you have to start with John Snow. John Snow was one of the first Epidemiologists, and he showed that cholera was water-borne, and debunked the (then-popular) Miasma theory. This Friday, organizations around the world will be marking his 200th birthday.hile some may argue that there were other pioneers of Epidemiology, including John Gaunt, Hippocrates and others, John Snow, if not the first Epidemiologist, is definitely one of the fathers of the field.

Cholera Epidemics in the 19th Century For most of the 19th century, most scientists, physicians and sophisticated lay people believed cholera was not contagious. The observation that a doctor could have daily contact with cholera patients without falling ill led to the conclusions that cholera was not transmitted from person to person.

Cholera Cholera is an infection of the small intestine by some strains of the bacterium Vibrio cholerae. Symptoms may range from none, to mild, to severe. The classic symptom is large amounts of watery diarrhea that lasts a few days. Vomiting and muscle cramps may also occur.hildren are mostly affected. Cholera occurs as both outbreaks and chronically in certain areas. Areas with an ongoing risk of disease include Africa and south-east Asia. While the risk of death among those affected is usually less than 5%, it may be as high as 50% among some groups who do not have access to treatment.

2010s Haiti cholera outbreak The outbreak occurred ten months after a powerful earthquake which devastated the nation's capital and southern towns on 12 January 2010. By the first 10 weeks of the epidemic, cholera spread to all of Haiti's 10 departments or provinces.he epidemic came back strongly in the 2012 rainy season, despite a localised delayed vaccine drive. In late June 2012, Cuba confirmed three deaths and 53 cases of cholera in Manzanillo, in 2013 with 51 cases in Havana. Vaccination of half the population is urged by the University of Florida to stem the epidemic.

Cholera bacteria infect more effectively with a simple twist of shape The bacteria that cause the life-threatening disease cholera may initiate infection by coordinating a wave of mass shapeshifting that allows them to more effectively penetrate the intestines of their unwitting victims, according to a study led by Princeton University.

- Causes. Cholera is caused by the bacterium Vibrio cholerae. These bacteria release a toxin that causes an increased amount of water to be released from cells that line the intestines. The increase in water produces severe diarrhea. People get the infection from eating or drinking food or water containing the cholera germ.

The infection is often mild or without symptoms, but sometimes it can be severe.

Vibrio cholerae Vibrio cholerae strains. Two serogroups of V. cholerae – O1 and O139 – cause outbreaks. V. cholerae O1 causes the majority of outbreaks, while O139 – first identified in Bangladesh in 1992 – is confined to South-East Asia. Non-O1 and non-O139 V. cholerae can cause mild diarrhoea but do not generate epidemics.

John Snow (1813 - 1858) He published his ideas in an essay 'On the Mode of Communication of Cholera' in 1849. A few years later, Snow was able to prove his theory in dramatic circumstances. In August 1854, 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.

Cause of Cholera Vibrio cholerae Serogroup O1 is the type of Vibrio cholerae that most often leads to cholera. Vibrio cholerae Serogroup O139, a Vibrio cholerae Serogroup non-O1 bacteria, is the other cause of the disease. Vibrio cholerae is native to the Ganges delta, which is in India and extends into Bangladesh.nce Vibrio cholerae is ingested, the bacteria travel to the small intestine where they begin to multiply. Vibrio cholerae then begins producing its toxin, which is the main cause of watery diarrhea, a characteristic symptom of cholera.

The theory was supported by leading figures in public health at that time, like Edwin Chadwick and Florence Nightingale, who held sway over public opinion.hen cholera first arrived in London in 1832, it was thought to be spread by a miasma” or bad smell in the atmosphere.

Cholera Cholera is an infectious disease that causes severe watery diarrhea, which can lead to dehydration and even death if untreated. It is caused by eating food or drinking water contaminated with a bacterium called Vibrio cholerae. Cholera was prevalent in the U.S. in the 1800s, before modern water and sewage treatment systems eliminated its spread by contaminated water.
