John Snow Father Of Epidemiology

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)

The book “The Great Influenza: The Story of the Deadliest Pandemic in History, written by John M. Barry, covers the progression of the Spanish influenza, especially in the United States. Barry focuses not only on the influenza itself, though, but also on the social influences that allowed the virus to flourish. The book covers how medical practices in the United States had risen up just in time to combat the virus, but, due to societal issues and the war, the doctors struggled in areas where they should have been successful.

We see also the work John Snow (physician) who discovered the polluted public water Well as a source of outbreak disease such as cholera in the poor areas in London. This was the starting point of epidemiology

John Hancock was born January 23, 1737 (according to the Julian calendar that was in use around that time, the date was January 12, 1736) in Braintree, Massachusetts. Hancock was the son of Reverend John Hancock of Braintree, Massachusetts and Mary Hawke Thaxter. After his

John Adams was born on October 30, 1735, on the family farm in the North Precinct of Braintree, Massachusetts. He was the second of five children to his parents John and Susanna Boylston Adams. John's father was his role model because he wasn't only a farmer by trade, but he also took on many other time consuming jobs around the community to help others. Everyone in his hometown in some way dealt with him because he owned the titles of: the deacon of the church, selectman, tax collector, constable, and the lieutenant of the militia. John's mother was from a very wealthy Boston family, but infamous for having a bad temper. She remarried in 1766 following the death of John's father five years earlier due to the flu epidemic. John

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

In the early 1900’s medicine was making some steps closer into some great improvements for health and better understanding of the human body. Doctors with sufficient knowledge of the human body and cures for diseases and viruses were scarce. People were much more concerned with government and politics, than health and medicine, until one of the greatest and most grotesque lethal pandemics that’s struck the earth in human history. This pandemic the “Spanish Flu” spread so rapidly and had an extremely high mortality rate. This was caused by the close contact of humans and poor cleanliness and sanitation, and the host (virus) and the body taking harsh action

John Quincy Adams was born on July 11, 1767 in Braintree, MA. John was the son of second President John Adams. While he was a child,around the age of 8, he got to experience something no other child would ever wonder, he watched the famous Battle of Bunker Hill on a hill top that was close to his farm house. John Quincy was never really allowed the freedom of being a child. From age 10 and up he went with his father to important meeting about the Revolution, Treaty of Paris, Etc. Soon after he became his fathers secretary of state.

John Hancock was born on January 23, 1727 in Braintree, Mass. He is the son of John Hancock and Mary Hawke. John Hancock (father) was a Harvard graduate and minister. They lived in a part of town which eventually became the

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.

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

This paper will discuss the communicable disease influenza. It will discuss the causes, symptoms, and treatments, as well as the demographics of interest. It will also discuss the determinants of health and how these factors contribute to the development of influenza. Included in this paper will be information on host, agent, and environmental factors. Lastly it will explain the role of the community health nurse in caring for those affected with influenza and the role they play in education and prevention.

John Adams was born in Massachusetts Bay Colony October 30, 1735. His father was a farmer, town councilman and a direct descendant of Henry Adams. Susanna Boylston Adams was his mother who came from a very prominent family. He was a political philosopher who was the second president of the united states from 1797-1801. He also served as the vice president under President George Washington. John primarily lived in Massachusetts but he also lived in England for 10 years because after the Revolutionary war, he decided to stay in England. He also lived in Paris and Philadelphia. John moved around a little but mostly stayed in Massachusetts.

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.

Epidemiology is the study of distribution and determinants of health-related states or events in specified populations and the application of this study to the control of health problems. The epidemiological triad model holds that infectious diseases result from the interaction of agent, host, and environment (CDC, 2012). Disease transmission occurs when the agent leaves the reservoir or host through a portal of exit, are the conveyed by some mode of transmission and enters through and appropriate portal of entry on infecting a susceptible host (CDC, 2012). This sequence is sometimes called the chain of
