Thesis:
John Snow formulated a theory on the transmission of cholera, improved the mode of administration of anesthetics, and made advancements in resuscitation. He is considered a father of epidemiology, even though many of his concepts were not accepted until years after his death. Among those who have left their mark on the development of public health is John Snow, a man who is considered a father of modern epidemiology. However, many of his concepts were not accepted until after his death. John Snow worked hard and published many great works. In this paper, I will briefly discuss John Snows background, his works, and the outcome of those works. John Snow was the son of a humble laborer in York, England. Snow’s father eventually became a farmer and landlord after acquiring a sufficient amount of property. Snow on the other hand took a different path in society, becoming an apprentice to William Hardcastle. After obtaining an education from several schools, Snow became a licensed apothecary, surgeon, and physician. John Snow first encountered cholera in 1831-32 in Newcastle. It was in the London epidemic of 1848-49 that Snow proposed that cholera entered the body through the mouth. In 1849, Snow wrote “On the mode of communication of cholera”. It was dismissed for lack of data. In 1841, Snow published his first work, entitled “Asphyxia and the resuscitation of still-born children.” He made the premise that respiration was essential to life. He observed that lower temperatures enhanced survival. Snow’s experience showed him that one in twenty newborns died at birth. Snow created a modified device to get air into and out of a newborns lung. In 1846, Snow heard about the use of anesthetics in America. Anesthetics…...

...Introduction Public Health Law is a tool for protecting and promoting the health of the public and it is guided by a set of three principles known as the Core Functions of Public Health, which includes assessment, policy development, and assurance (Center for Disease Control and Prevention, 2012; Florida Department of Health, 2012). It plays a critical role in reducing illness and premature death. It also examines the authority of the government at various jurisdictional levels to improve the health of the general population within societal limits and norms, in addition to, improving the likelihood that citizens nationally and globally can lead healthy, long, and productive lives (Public Health Law Association, 2010; Wikipedia, 2012). The Core public health functions provided by public health law define the important role that the public health system plays, at the local, state, and national levels, in maintaining the health and safety of citizens (Minnesota Department of Health, 2012). These functions represent the spectrum of activities and responsibilities that are shared among public health system partners (Key Elements of Wisconsin’s Public Health System, 2012). Public Health Core Function Principally Addressed In the article, Public Health Law in a New Century, Lawrence Gostin mainly addressed the importance of policy development by the government in public health. The government is the single most important force shaping our healthcare system (The Role of......

...NJ122 “Public Health Assignment” Oliver Stacey September 08 Public Health and Professional Practice – Smoking This essay aims to describe the epidemiology of smoking. The essay is going to notify the nurse’s role into promoting public health. I choose the topic of smoking due to the realisation of how many patients were smokers on the day surgery ward, which my placement was held. Today, tobacco consumption is recognised as the UK’s single greatest cause of preventable illness and early death with more than 114,000 people dying each year from smoking-related diseases including cancers (Canceresearchuk.org). Smoking also causes a substantial amount of cost to the NHS (National Health Service) every year. Rather than on health on an individual, public health focuses on health and disease in populations or communities as a whole (Ewles, Simnett 2003). Although there has been a decline of smoking, which could be due to a number of things, for example the smoking ban placed in the United Kingdom, smoking still sets high figures of deaths around the world. Around 90% of lung cancer cases are caused by tobacco smoking and, in addition, the 2002 IARC Working Group stated that tobacco smoking can also cause cancers of sites such as the stomach, pancreas, liver, lower urinary tract etc, (Cancerresearchuk.org). Smoking also costs the NHS £1.4 - £1.7 billion per year, (DOH, 2005). This in hand affects the role of the nurse, as smoking must always be evaluated when......

John Snow and the Cholera Outbreak

...The Broad Street cholera outbreak was a severe outbreak of cholera that occurred near Broad Street in the Soho district of London, England in 1854. This outbreak is best known for the physician John Snow's study of the outbreak and his discovery that contaminated water, not air, spread cholera. This discovery came to influence public health and the construction of improved sanitation facilities beginning in the 19th century. Later, the term "focus of infection" would be used to describe places like the Broad Street pump in which conditions are good for transmission of an infection. In the mid-19th century, the Soho district of London had a serious problem with filth due to the large influx of people and a lack of proper sanitary services: the London sewer system had not reached Soho. Many cellars (basements) had cesspools underneath their floorboards. Since the cesspools were overrunning, the London government decided to dump the waste into the River Thames. That specific action contaminated the water supply, leading to a cholera outbreak. On 31 August 1854, after several other outbreaks had occurred elsewhere in the city, a major outbreak of cholera reached Soho. John Snow, the physician who eventually linked the outbreak to contaminated water, later called it "the most terrible outbreak of cholera which ever occurred in this kingdom."[1] Over the next three days, 127 people on or near Broad Street died. In the next week, three quarters of the residents had fled the area....

John Snow and Cholera Control

...Regardless of how it came to pass, John Snow became one of the heroes of medical science by discovering how cholera was transmitted. It was a tough journey for him. Being a farmer’s son proved it difficult for him to convince a disbelieving medical establishment that his findings were valid. He trekked all the way to the metropolis. Little did he know that he will be the savior of this great city. His story is legendary. To date, he remains a towering figure in many fields. Psychologists have a few lessons that they can learn from him. He was born in York. A son of Yorkshire labourer who became a relative good farmer. At the age of fourteen, the youth was connected to an enlightened surgeon who was his mentor. His first encounter with cholera was when it swept through the nearby town during the 1831-1832 epidemic. It broke again in 1846, but this time round, Snow was in London. By this time, he had completed medical training. He was a well know investigator and researcher by the late 1840s since he had already published several groundbreaking studies that included research into anesthesia. From the onset, snow was a high-minded young man. As he advanced in age, he maintained his integrity. As a bachelor, he was glued to his work and in a great manner dedicated his life to scientific and humanitarian pursuits. The basis of investigations into cholera began when he started researching on Anesthesia. He had a good understanding of the operation of gases and from there, he found...

The government take into considerations the health needs of the people and acts on the findings demonstrated through national statistics. The government act on these findings by passing laws that are considered to power the overall health and well-being of the nation.

Health Influences

...Health Influences Southern New Hampshire University Health Influence The World Health Organization defined Health on April 7, 1948. Health is defined as “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity,” (World Health Organization (WHO), 2003). This definition has not changed in over 67 years. The current definition of health is unrealistic when compared to our growing population. As our population ages, the environment changes, treatment modalities improve our symptoms but do not cure, it is impossible to have “a state of complete physical, mental and social well-being”. Many people are faced with multiple co-morbidities. We can focus on disease prevention and treatment of chronic diseases. The definition of health should reflect this change in our growing and aging population. Florence Nightingale Florence Nightingale was instrumental in influencing health care policy and the perception of health. Florence Nightingale contributed to the care of the sick and injured during her time, and to the modern practice of nursing care and policy. “In less than 100 pages, she gave the world a handbook for taking care of the sick and a blueprint for running a healthcare system,” (Lim, 2010). Florence Nightingale sought to improve the care and environmental conditions of each patient she treated. It is her hard work and determination that allowed for woman to be properly trained to “provide a safe and...

This strategy involves keeping track of people’s health/keeping an eye on everyone though statics. By tracking changes in the health of the population health professionals are able to alert people to potential problems, for example regular check-ups, at doctors for asthma or Dentist to check up on teeth and make sure they are in good condition plus Orthodontic. Also the NHS provide a free midlife MOT to check people aged between 40-74, to make sure they are in good health and to help reduce the number of elderly who suffer with high blood pressure. Also for HIV, they monitor the health of the population with HIV tracking the number of people with HIV within the population. This helps the NHS find out the population of people with HIV in order for them to take further actions. -Identifying the health needs of the population. This strategy involves identifying health needs, including those that are common problems/ illness that are considered a major problem. For example identifying the illness and providing support through services or medicine, advert are a great way that can get you aware, and provide you with health awareness that is common in the population.

...Urban government and politics Name Course Date The book, “Place Matters: Metro politics for the Twenty-First Century,” by Peter Dreier, John Mollenkopf and Todd Swantrom are an overall view of various issues faced by a majority of modern American cities. This includes commercial and social aspects inequalities. The book also puts emphasis on the role played by these inequalities (Dreier, Mollenkopf & Swantrom, 2005). Among the emphasis, are their role in segregation of areas which led to the social classification as either “rich” or “poor” and its aftermath in the eventual disintegration of the cities’. Apart from this, book also shows the relationship between this situation and the political mechanisms involved. This connection, the author argues, plays a crucial role in either improvement of the cities’ or deterioration. The authors also present proposals on how to stop the deterioration and transform them for the better (Dreier, Mollenkopf & Swantrom, 2005). This paper tries to assess the arguments presented by the authors in tackling the problem. This evaluation is based on the description of the authors’ proposal and its feasibility to various cities in the U.S. This petition will try to prove that indeed no matter how “radical” an idea is, its feasibility would be meaningless without a practical application. Moreover, the book tackles continued disparity among the rich and poor and the relevance places hold in......

...changing focus of public health by Maria Joyce Key sections include: Environment, infectious disease, locating public health, the enlightenment, the Sanitarians, national provision of services, the inception of the National Health Service, ‘crisis in health’, The New Right, The Third Way, new public health. Public health, the new ideology may be taken to mean the promotion of healthy lifestyles linked to behaviour and individual responsibility supported by government action; whereas traditionally the description tended to relate more to sanitary reform and ‘healthy conditions’. The chronological development of public health is mapped out, supported by the outlining and discussion of the emerging themes and influences pertaining to the study of public health. The approach to public health is positioned alongside the health of the population and the prevailing political/societal influence at the time. Public health is impacted on by poverty and environmental factors. Presently government policy to improve public health is delivered in a strategy that recognises the need for health improvement at times when the greatest impact on health is poverty and exclusion. The evidence reviewed demonstrates clearly that poor health without appropriate resources or intervention is cumulative and that the ‘right’ form of intervention can bring about long term health gains. Intervention from a national agenda needs to include individual’s health and the health of the community......
