...Assignment: Epidemiology Paper Grand Canyon University Concepts in Community and Public Health NRS-427V-0501 Benchmark Assignment: Epidemiology Paper Hepatitis B The definition for Hepatitis changes with whom you ask. To some it means a horrible painful way to die while others are able to look at it as a disease. The word Hepatitis means liver inflamation. The liver is a large, glandular, reddish-brown organ located in the upper right side of the abdomen. It consists of 5 lobes and secretes bile into the gallbladder and into the small intestine and aids in the digestion of lipids. Hepatitis is often caused by a virus. Hepatitis A, B, and C are the most common types in the United States but there is also a type D, E, and there was thought to be an F but after a thorough investigation they failed to prove its existence. Hepatitis B (HBV) is a liver disease that is contagious. It is believed that approximately 1.2 to 1.4 million people in the United States have chronic Hepatitis many of which are not officially diagnosed. There are two stages or categories of Hepatitis B, chronic and acute. Chronic Hepatitis B is anyone who has had the virus for longer than 6 months ("Hepatitis B," 2010) and at this point it is considered a lifelong illness. The beginning or acute phase of Hepatitis B is the first 6 months of being exposed to the virus. During this first 6 months some people are able to fight the infection off and get rid of it. Symptoms may vary and young...

...Hepatitis B: An Epidemic The World Health Organization defines epidemiology as “the study of the distribution and determinants of health- related states or events, and the application of the study to the control of diseases and other health problems” (CDC, 2014). Determinates of health are “the circumstances in which people are born, live, work and age as well as the systems put in place to deal with illness”. The communicable disease chain is a model beneficial to integrating the many concepts of communicable diseases (Maurer & Smith, 2009). A nurse has a significant role in preventing and controlling infectious disease. A vital factor in preparing for clinical nursing practice is having an understanding of the infection process and techniques on how to prevent it. This paper focuses on a prevalent communicable disease, Hepatitis B. This writer will give a description of the disease, the demographic affected by the disease, what determinates contribute to the development of Hepatitis B, she will discuss the epidemiology triangle of the disease, explain the role of the community health nurse in this community, and explain various agencies and resources patients diagnosed with this disease can access. Hepatitis B is a serious liver infection caused by the hepatitis B virus. Two types exist: the acute illness and the chronic illness. In the acute illness, the immune system is able to rid the body of the virus and a complete recovery may occur in a few months. Chronic hepatitis...

...Hepatitis B is the most common liver infection in the world. Worldwide, about 350 million people are chronic carriers of HBV (Hepatitis B Virus), among these carriers, more than 620,000 die from liver-related diseases each year. In the United States, hepatitis B mainly affects adults aged between 20-50 years. About 800,000 to 1.4 million Americans are chronic hepatitis B virus carriers, and the disease causes about 3,000 deaths each year. The good news is that infection with HBV is usually preventable because there is an effective vaccine. Use of the vaccine has resulted in an 82% decrease in the number of new infections reported in the United States each year. (www.emedicinehealth.com/hepatitis/article_em.htm) Figure 1: Estimated and reported cases of hepatitis B in the United States. Rates have fallen significantly since 1991 when routine vaccination of children was started. (www.emedicinehealth.com/hepatitis/article_em.htm) Hepatitis B is an infectious hepatitis caused by the hepatitis B virus (HBV). This infection has two possible phases; 1) acute, 2) chronic. Acute hepatitis B refers to newly acquired infections. Affected individuals notice symptoms approximately 1 to 4 months after exposure to the virus. In most people with acute hepatitis, symptoms resolve over weeks to months and they are cured of the infection. However, a small number of people develop a very severe, life-threatening form of acute hepatitis called fulminant hepatitis. Chronic hepatitis B is an infection...

...Public Health Hepatitis B Jorge Cruz Jr Grand Canyon University According to the Hepatitis B Foundation, the virus has infected about 2 billion people worldwide, which is about 1 person out of every three (Our Accomplishments, 2014). Hepatitis B virus or the HBV is a virus that can cause a lifetime of damage to the liver. “Hepatitis” on its own refers to the inflammation of the live, although there are many causes of inflammation of liver the family of the hepatitis viruses are the most common with Hep A, B, and C being most prominent of the family. Although the family of the hepatitis’ viruses are similar in structure, they differ in transmission and infection. For instances, Hepatitis A is transmitted fecal to oral, whereas Hepatitis B and C are transmitted through exchange of bodily fluids (Hepaitits B, 2008). Hepatitis B can be spread when infected blood, semen, or any other bodily fluid comes in contact with a non-infected person’s bloodstream. The CDC, provides possible situation when this occurs, for example, during birth (mother is infected could pass down to infant), during sex, or when sharing items that come in contact with a infected person’s blood like toothbrush, needles, or razors. Since it is spread through bodily fluid people at risk for infection are those who come close contact with other people’s bodily fluid frequently this includes but not limited to healthcare workers, men who have sex with men, infants of infected mothers, people with multiple sex...

...Epidemiology Hepatitis B affects 1 in 3 people worldwide (Hepatitis B Foundation [HBF], 2014). A vaccine has been available for over 30 years, yet it is the ninth leading cause of death worldwide (HBF, 2014). The epidemiology of hepatitis B, the role of the community health nurse along with the knowledge about what is being done to combat and reduce the impact of the virus gives a comprehensive look at hepatitis B. Hepatitis B virus (HBV) is a DNA virus, and belongs to the Hepadnaviridae family of viruses (World Health Organization [WHO], 2014). The virus interferes with liver function and liver damage is caused from the inflammation from the body’s immune response. Jaundice is the classic symptom of liver disease. For correct diagnosis, a Hepatitis B blood panel is needed. Symptoms of the disease may include fever, loss of appetite, nausea and vomiting, joint pain, weakness, fatigue, dark urine, abdominal pain and jaundice. These symptoms can range in severity, with onset from one to four months after hepatitis B exposure (Mayo Clinic, 2014). Some patients do not experience symptoms; these patients have the potential to become chronic carriers and a source of transmission to others without being aware of it (WHO, 2014). Hepatitis B is transmitted from direct contact with infected blood, body fluids, and sexual intercourse. A break in the skin barrier must be present for blood to infect a person. Sharing of an infected needle is another source of infection....

...related to each other or to hepatitis B virus and they differ in their structure, also in the way they are spread among individuals, also in the severity of symptoms that they can cause along with the way they are treated. In the United States alone the rates of new infection were the highest among people aged 25to 44 years and lowest among those younger than 15 years of age. This reflects that the major of transmission of hepatitis B is through sexual transmission, illicit drug use, and exposure to infected blood. The good news is that there has been a 75% decrease in newly diagnosed cases of hepatitis B during the past decade. The decrease is attributed to increased vaccination and heightened public awareness of HIV/ AIDS this has resulted in safer sexual practices. When a person first gets hepatitis B this is an ‘acute’ infection. Most people are able to let the virus run its course and this will cure the infection. Then there are some which can not clear the infection this is called ‘chronic hepatitis B this usually life-long. Hepatitis B is spread mainly by exposure to infected blood or body secretion in the infected individual. The virus can be found in semen, vaginal discharge, Breast milk, and saliva. Hepatitis B is not spread through water, food, and or casual contact. The most common transmission is sexual contact, followed by using contaminated needles for injection of illicit drugs, tattooing, body piercing. Also Hepatitis B can be transmitted through sharing...

...“Hepatitis B is a virus that infects the liver; it can be acute or chronic. Having chronic hepatitis B can increase your risk of developing liver failure, liver cancer or cirrhosis — a condition that causes permanent scarring of the liver”. (© 1998-2014 Mayo Foundation for Medical Education and Research. All rights reserved.) “In the United States, approximately 1.2 million people have chronic Hepatitis B. Unfortunately; many people do not know they are infected. The number of new cases of Hepatitis B has decreased more than 80% over the last 20 years. An estimated 40,000 people now become infected each year”.(http://www.cdc.gov/hepatitis/hbv/pdfs/hepbgeneralfactsheet.pdf) Many experts believe this decline is a result of widespread vaccination of children when the liver cannot remove harmful toxins from the blood, fight infection, also help digest food, store important nutrients and vitamins a person is not capable of living without a liver. Hepatitis B infection may be either short-lived (acute) or long lasting (chronic). Acute hepatitis B infection lasts less than six months. Your immune system likely can clear acute hepatitis B from your body, and you should recover completely within a few months. Most people who acquire hepatitis B as adults have an acute infection, but it can lead to chronic infection. Chronic hepatitis B infection lasts six months or longer. When your immune system can't fight off the acute infection, hepatitis B infection may last a lifetime, possibly...

...Your Liver and Hepatitis. The Liver Facts . One out of every 10 Americans is affected by liver disease. Liver disease is one of the top 10 causes of death in the United States. There are more than100 liver diseases. The good news is we can help prevent the liver diseases and keep it healthy. Overview of the liver. The liver is the second largest organ in the body and is located under the cage on the right side. It weighs about three pounds and is shaped like a football that is flat on one side. The liver performs many functions in the body. It processes what you eat and drink into energy and nutrients that your body can use. The liver also removes harmful substances from your blood. Functions of the liver include: • Filters your blood • Makes proteins, including blood-clotting factors (needed to help you heal) • Stores vitamins, sugars, fats, and other nutrients • Helps regulate hormones • Releases chemicals and nutrients into the body when needed • Makes bile needed for digesting fats Liver damage can lead to swollen, shrunken, hard, or scarred liver tissue. Such livers do not work well, and the person can get very sick, or even die, if the liver stops working altogether. Symptoms of liver disease Acute (When symptoms occur suddenly it is categorized as acute process) Tiredness or weakness Jaundice (yellowing of the eyes and skin) Fever Nausea and vomiting Dark urine or very pale colored...

Jack, Graduate Chair ii Abstract A method was developed to create Computer-Aided-Design (CAD) models for bones of the human body utilizing medical imaging data. The human hand was chosen as the subject of the research. Computed Tomography (CT) imaging was chosen to provide a volumetric data set. This data set was visualized through an isosurfacing technique utilizing the marching cubes algorithm. The original CT data set contained slices that were not aligned with the natural orientation or long axis of the bones. Transformation matrices and linear interpolations were used to generate a data set of slices oriented along the natural axis of the bones. Contours were created on these slices through an edge-tracking method. B-Spline curves were then constructed utilizing the contour’s vertices...

... Culture & Disease Paper Hepatitis is a viral disease that affects people of all ethnic groups, races and various religious backgrounds. However, compared to the other racial or ethnic groups’ Asian population are more likely to be a higher risk to inheriting the disease than any other racial or ethnic group. The subject of discussion in this paper is how Hepatitis propagates making the Asian population in particular at risk to this disease (U.S. National Library of Medicine, 2012). What is Hepatitis? Hepatitis is the swelling of the liver that makes it to stop working well. There are five main types of known Hepatitis, Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D and Hepatitis E (U.S. National Library of Medicine, 2012). Liver is organ of the body that is responsible for the variety of functions such as Detoxifications, store vitamins, maintain production of the biochemical needed by one’s body for digestion, and maintain the proper glucose levels in the body. The liver is also responsible in production of certain hormones required by the human body, and production of urea the main substance present in the urine. Hepatitis is a viral infection caused by a virus that attacks the liver leading to inflammation and demising its ability to perform the required functions. The individuals that carry the Hepatitis virus have no symptoms and can take decades to show up when the liver...
