How Dr John Snow applied the two uses of epidemiology to deal with cholera outbreak in London?
The great Dr. john Snows was investigating the cholera epidemic in London in 1854. He noted that the flow of patient has come from particular geographic area. Then he could find out that the particular area was supplied by one single pipe line. Then he concluded that the water got contaminated there through that pipe line. It was the land mark discovery that lead to the control of water borne communicable diseases. Now that proves the role of geographers in control of the diseases. By the way human being is the social animal. The role of every individual is very important. The most useless person can prove to be great nuisance to the society. So it is better to know that every person in the society is your relative. Every individual should be given due respect and importance. You can not be happy and safe unless every body is happy and safe. This is true for every individual inhabitant of this earth.

What caused the deaths of 11500 Londoners in 1853?
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.
How did john snow vaccinate cholera?
John Snow did not invent the cholera vaccine; he was a pioneer in epidemiology and is best known for his work in identifying the source of a cholera outbreak in London in 1854 by linking it to contaminated water from a public pump on Broad Street. His findings helped establish the importance of clean water in preventing disease transmission.
What did john snow find out?
John Snow was a British physician who is considered one of the founders of modern epidemiology. In 1854, he conducted a groundbreaking study during a cholera outbreak in London and determined that contaminated water from a specific public pump was the source of the disease, leading to improvements in public health practices.
In the 18th and 19th century what was the bond street pump?
Do you mean the "Broad Street Pump" (19th century cholera outbreak in London)?
Why is john snow's work important today?
John Snow's work is important today because he laid the foundation for modern epidemiology. His investigation of the 1854 cholera outbreak in London demonstrated the role of contaminated water in spreading disease and led to improvements in public health practices. His work continues to influence how we respond to and prevent infectious diseases.
John Snow is called the father of modern epidemiology because?
In 1854 John Snow mapped the cases of cholera in Soho, London, and realised that almost all of them were likely to have taken their water from the same pump. The spread of cholera stopped when the handle of the Broad Street pump was removed.
Which scientist proposed a link between contaminated water and cholera?
It was a doctor, John Snow, in London England, during the cholera outbreak in 1853. Those that drank beer, were free of the plague. Isolating a contaminated water pump, proved the theory.
Who is the English physician who used maps to trace the source of a deadly outbreak of disease in London in 1854?
Name of the physician was Dr John Snow. The cholera out break occurred near Broad street in Soho district of London. (Now renamed Broad-wick street.)
How was john snow's ghost map an application of GIS principles?
John Snow's Ghost Map was an early example of using spatial analysis to track the source of a cholera outbreak in London. By mapping the locations of cholera cases, Snow was able to pinpoint a contaminated water pump as the source of the outbreak. This application of GIS principles helped demonstrate the importance of spatial data in identifying patterns and making informed decisions in public health.
Did Cholera affect other country then London?
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.
When did scientists discover how cholera was spread?
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.
How did John Snow use a map to prove his theory?
John Snow used a map to plot the locations of cholera cases in London during the 1854 outbreak. By doing so, he was able to identify a concentration of cases near a particular water pump on Broad Street. His analysis helped identify the contaminated water source and supported his theory that cholera was waterborne.
