Cholera
Cholera bacteria was first isolated by Filipo pancini 1812-1883, 84 years before he was actually credited with its discovery. A paper was published by him in in 1854 during the Asiatic cholera pandemic of 1846-63. in it he has the description of the cholera causing organism and its relationship to the disease. It was titled Microscopical observations and pathological deductions on cholera.
First, London is a city, not a country. And yes, Cholera can be found in almost all countries if sanitation is not adequate or water has been infected.
The total number of people who died in the 1854 London cholera epidemic is 616. See related link for an excerpt from a book on the subject: This site also contains links to some really cool period maps, as well as to a firsthand account of the epidemic written by Dr. John Snow, the doctor who discovered the cause of the outbreak and treated many people affected by it.

During the 1840's the residents of London suffered from influenza, cholera, typhoid fever, typhus, small pox and scarlet fever. Cholera and influenza ravaged London consistently from the 1830's to the late 1840's.
He decided to sort out the problem in London of 'The big stink', which was one hot summer where the rubbish in the Thames became an unbearable smell. He devised a sewage system. In the process of this, he figured that the dirty water may have something to do with the cases of Cholera. After turning one off the water pumps in the London Courtyard, cases of cholera in a certain part of London stopped completely. Hope I Helped.
John Snow (1813-1858) was a London physician and a founding father of modern epidemiology. He was a pioneer anesthetist who invented a new kind of mask to administer chloroform, which he used on Queen Victoria to assist at the births of her two youngest children. He was an astute clinician and kept meticulously detailed notes about his patients and their diseases. His work on cholera was of lasting value because it demonstrated several fundamental intellectual steps that must be part of every epidemiologic investigation. He began with a logical analysis of the then available facts, which demonstrated that cholera could not be due to a "miasma," a theory that was then popular. It could only be caused, Snow determined, by a transmissible agent, most probably in drinking water. Having arrived at this logical conclusion, Snow conducted two epoch-making epidemiological investigations in the great cholera epidemic of 1853 to 1854. One was a study of a severe, localized epidemic in Soho, using analysis of descriptive epidemiologic data and spot maps to demonstrate that the cause was polluted water from a pump in Broad Street. His investigation of the more widespread epidemic in South London involved him in an inquiry into the source of drinking water used in some seven hundred households. Snow compared the water source in houses where cholera had occurred with that in houses where it had not. His analysis showed beyond doubt that the cause of the epidemic was water that was being supplied to houses by the Southwark and Vauxhall water company, which drew its water from the Thames downriver, from London, where many effluent discharges polluted the water. Snow found that very few cases occurred in households supplied with water by the Lambeth company, which collected water upstream from London, where there was little or no pollution. Snow's work was remarkable in that it was completed thirty years before Robert Koch identified the cholera bacillus. Snow published his work in a monograph, On the Mode of Communication of Cholera (1855). This classic book has been reprinted in several modern editions and is still used as a teaching text in courses of epidemiology.
The Black Death.
Parry had been in ill-health since 1834 because of the strain of his Australian work. In 1854 there was a cholera epidemic in parts of London, and while it is not certain that Parry was suffering from this condition, he was advised to consult with certain doctors abroad. By June 1855, Parry was in Ems, Switzerland, and died there on the 8th July, of what we are not certain.
In 1854 there was an outbreak of Cholera in London, which killed 10,000 + people. Official investigations into this proved that cholera is a water borne disease, and was the starting point for the science of Epidemiology.
