Epidemiology Paper on Tuberculosis

Tuberculosis (Mycobacterium tuberculosis), also known as TB, is a disease spread by respiratory inhalation of droplets that contain the bacteria. Tuberculosis is an ancient disease that has been traced back at least 9000 years. In 1882, Dr. Robert Koch was the first physician to describe Mycobacterium tuberculosis as the germ responsible for tuberculosis. However, treatment that was evidenced based was not put into practice until the 20th century. It is estimated that 2 billion people around the world are infected with the TB bacteria. Approximately 5 to 10 percent of these infected people will actual develop active TB and experience the life-threatening symptoms of the disease. Tuberculosis remains a deadly infection around the world claiming 1.7 million lives per year. TB is generally recognized as a respiratory disease but can also attack the brain and spine, circulatory system, gastrointestinal and genitourinary systems as well as the skin, bones and joints. (Furlow, 2010) The groups of people in the United States that are at risk of developing tuberculosis are those infected with HIV, the homeless, prisoners, poor individuals who live in urban areas, minorities such as African American’s, Hispanics and Asians. Healthcare workers are also at risk in the US and around the world. Countries outside of the US hardest hit by TB are in Asia and sub-Saharan Africa. Rates for infection among American born individuals has steadily dropped since 1990 while the numbers for foreign-born individuals infected has remained the same and is the largest group in America infected with TB. (Maurer & Smith, 2013) Tuberculosis germs are spread in the air when an infected individual coughs, sneezes, speaks or sings. According to the CDC, these germs can stay in the air for several hours. People who breathe this air

Tuberculosis

...Tuberculosis also known as TB, is a serious disease that affects millions of people world-wide each year. This respiratory illness usually infects the lungs, although it can affect any part of body or both at the same time. The agent that causes TB is mycobacteria such as Mycobacterium tuberculosis. Mycobacteria can be found easily in the environment such as soil and water but M. tuberculosis can only survive in its human hosts. About one-third of the human population has tuberculosis. This highly contagious disease is spread through droplets in the air when an actively infected person coughs, spits, talks, sings, or sneezes and an uninfected person is close and catches the bacteria by inhaling it. A large majority of those infected do not have symptoms, which is known as latent tuberculosis. Ten percent of those with latent TB developed an active infection in their lifetime and about half of those with active TB will die from the disease. Symptoms may be mild the first few weeks or months of the disease, easily spreading to others due to how highly contagious it is. The farthest back scientists have discovered TB is 2400BC through the spinal fragments of ancient Egyptian mummies. It was also found in bone fragments in South American from 750BC. Records prior to the 19th century have described this disease which then was also called consumption, white plague, dread disease, or the king’s evil. The spread of TB reached a peak during the 19th century Industrial Revolution in...

The spread could happen via different types of transmission depending the disease it could be airborne or contact with bodily fluids. As health care providers it is our duty to teach and educate the population about communicable diseases to inform them on how they are spread and prevented. The following essay will briefly discuss tuberculosis and the role of a community health nurse. “Tuberculosis is a highly communicable disease caused by Mycobacterium tuberculosis infection” (Winkelman, Workman, & Hausman, 2010). It is transmitted via airborne route for example if an infected person laughs, whistles, coughs or sneezes. The population at risk for developing tuberculosis are people who have direct contact with a person infected with tuberculosis. People who have a low immune system are also at risk for developing tuberculosis. As well as people that live in crowded areas like long term facilities or prisons and homeless people. Signs and symptoms include persistent cough, weight loss, anorexia, night sweats, fever or chills and dyspnea. Tuberculosis can be diagnosed with the tuberculin skin test a small amount of fluid is injected to the patient’s forearm the test needs to be read within 48 to 72 hours.

Native American Health

...Health Care Disparities of Native Americans Grand Canyon University Health Care Disparities of Native Americans For many years, the Native American lived a balanced, spiritual lifestyle in which the body played a vital role in the trio with the spirit and mind. One may presume the Native American to be the least at risk for health issues. Yet, they are plagued with several risk factors for chronic diseases. In fact, one adult Native American out of five will suffer from two or more chronic health issues (CDC, 2014). How did a racial community evolve from living off the land full of fresh vegetables, and fishing for lean proteins to be found with such a downtrodden health care outlook? This essay will answer this introductory question as a compare and contrast to non-American Natives’ health statuses are presented. Today, healthy living and good nutrition is not a common finding within 566 known tribal communities or more than 5.2 million American Indians existing within the United States (CDC, 2014). The American Indian is categorically within the highest risk for many chronic diseases such as diabetes, obesity, and alcoholism. Motor vehicle related injuries and deaths rates are also estimated to be 2-4 times the rates of other races and ethnicities. Infant death rates are also significantly higher compared to non-American Indian families (CDC, 2014). To Native Americans health promotion involves a holistic view. A harmony exists within...

Herpes Simplex Virus

...I chose to study this topic is more on how herpes affects a person emotionally. Why should a disease like this which rarely causes great physical problems, be such trouble to many people? It is not as devastating as tuberculosis. Its not a killer like cancer. And it is not as disabling as the flu. It isn't as bad a smoking is to your health, so why should so many people care about it. I think that the main reason is that herpes affects the persons personality. To many, there is nothing more important then that persons genitals. One's genitals gives one the ability to love and to be loved. Another reason is that this virus, unlike many in today's society, is incurable. With todays fast food restaurants, great health insurance, and one hour prescriptions, people have a hard time dealing with herpes being incurable. The incurability and recurrent nature of herpes makes it a control issue and no one likes to lose control. There is an unbuilding factor in this issue. There is always new research going on for this disease. This topic interests me on an great level. I myself get cold sores and I love to learn of new things that happens to others and cures they are working on. This study can help others for a cure, because I think a cure is greatly needed. In this essay I will examine several case studies and their results. I will also include a "Most Common...

Examining the Health Effects of Tattoos

...9 April 2013 Examining the Health Effects of Tattoos A tattoo is classified as a form of body modification. Tattooing is presently under strict hygiene rules because of the risk of infection. Tattoo artists must wear gloves and it is mandatory that the ink and needles be on single use. There are several forms of hepatitis that can be transmitted among the most severe of infections. According to theory, of all infections, HIV can even be transmitted. By inserting ink into the dermis layer of the skin that is just about impossible to rub out or remove, the tattoo is made. But only through the change of the pigment. Through this entire process, the blood becomes tainted. Tattoos are really a form of art, more specifically body art. Many of them have significant meaning while many do not. People of all lifestyles enjoy it. While tattooing is a hobby and/or done for beautification, it is vital to recognize that it is a decision and life-long commitment where health must also be taken into consideration. Tattoos are popular, and some people experience the need for meaningful ones in certain groups of society. Minor to major health effects are sometimes brought about and there is proof. The existing fact is that there is health effects involved in tattooing. Continually becoming popular is tattooing. This is especially true among adolescents.

Public Health Paper

...From past to present; the 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...

...The Ethical and Legal Complexity of Medical Tourism: Questions of International Justice, Economic Redistribution and Health Care Reform Professor Sarah McBride Toro Longe April 18, 2010 M.J. Thesis in Health Law Abstract This is an essay on medical tourism in the United States of America (U.S.). It includes a brief history of the U.S. health care system, examines the social, cultural, ethical, and legal issues that have affected health care changes in America. With the number of Americans going overseas to seek medical care steadily rising, the American insurance industry expanding benefits, and the Joint Commission accrediting facilities for globalization of the health care marketplace, medical tourism should become increasingly important in the health care industry. While there are many reasons for patients seeking health care outside of their own country, one that is particularly easy to overlook is the outsourcing of health care and its effect in U.S. and around the world. The purpose of this paper is to examine the concept of medical tourism, noting the specific medical tourism destinations, presenting reasons for the recent increase in medical tourism, and examining the risks and benefits, as well as wrestling with the challenging ethical and legal issues inherent in medical tourism. The paper will conclude with consideration of the role of the law in medical tourism. Introduction Over the past 100 years, the United States of America (U.S.) has changed greatly...
