Epidemiology Paper Vulnerable populations are "those with a greater than average risk of developing health problems by virtue of their marginalized socio-cultural status, their limited access to economic resources, or personal characteristics such as age and gender" (De Chesnay & Anderson, 2008). Infants and young children are vulnerable to a host of healthcare problems, they are susceptible to viral infection especially respiratory infection such as Respiratory Syncytial Virus. In this paper, the author will define and describe epidemiological triangle as it relates to respiratory syncytial virus (RSV), types of epidemiology, and levels of prevention of RSV.
Epidemiology Definition Epidemiology is defined as "the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to control of health problems" (Stanhope & Lancaster, 2008). The study of epidemiology is important because it search for causes or factors that are related with increased risk or likelihood of disease, it deals with group of people rather than with individual person, and it helps public health with decision making and aids in developing and evaluating interventions to control and prevent health problems (CDC, 2012). Epidemiology is used to "monitor the health of various populations, understand the determinants of health and disease in communities, and investigate and evaluate interventions to prevent disease and maintain health" (Stanhope & Lancaster, 2008). Epidemiologist treat communities and populations by looking at disease transmission, exposure, possible for spread of disease and ways to avoid the return of disease, just like a physician treats an individual. Epidemiology is considered "the core of science of public health and is…...

...Epidemiology and Vulnerable Population NUR/408 January 14, 2013 Theresa White Epidemiology and Vulnerable Population This paper will define epidemiology and vulnerable population. The methods and steps involved in the epidemiology process will be discussed. The diseases of a specific vulnerable population and emphasis of one disease will be examined with cultural, ethical, and legal considerations. The epidemiology triangle is explained and evaluating the feasibility of prevention will be explored with definitive steps for prevention. Epidemiology and Vulnerable Population Stanhope and Lancaster (2012) states “epidemiology is the study of the distribution and determinants of health-related events in human populations and the application of this knowledge to improving the health of communities (p. 282). In many communities there populations at risk for to specific health care problems creating a vulnerable population. “Vulnerability is a general concept meaning “susceptibility,” and its specific connotation in terms of health care is at risk for health problems” (De Chesney, 2008, p. 3). As Stanhope and Lancaster (2012) identify “epidemiology is a multidisciplinary enterprise that recognizes the complex interrelationships of factors that influence disease and health at both the individual level and the community level; it provides the basic tools for the study of health and disease in communities” (p. 282). In every community there are vulnerable......

...Applying Epidemiology Charles B. Moore HCA 415 Instructor: Quida Davis April 27, 2014 Applying Epidemiology A mother of a young child called the Vermont Department on February 5 to report the possibility of a foodborne disease outbreak after her child aged 5 years and two other children of her neighbor aged 7 and 10 years became ill with a lot of vomiting and diarrhea that took place within an interval of 12 hours. The child’s sickness became severe that the mother took her to a local hospital where she was kept at the emergency department. The mother stated that the child complained of nausea at 10 o’clock the February 2nd, later, the child began vomiting and having multiple episodes of diarrhea, she was not able to eat or drink anything without vomiting. In the evening, the woman took the child to the local hospital where she was admitted at the emergency department, here they noted the child was dehydrated and had a high fever. The stool and blood specimen of the child was collected and the child was given intravenous fluids as a treatment and later she was released; the following day the mother made follow ups on the test results for the child and it turned out the stool culture displayed negative results for usual bacteria (Brehm-Stecher et al, 2009, p. 1774). Two children who were nearby neighbors reported to have nausea, diarrhea, vomiting and fever, these were similar symptoms that the other child had even though these two children were not as ill as the......

...Thesis How has Chicken Pox evolved over time related to advances in community and public health nursing? Chicken Pox is a very common childhood disease caused by the Varicella-Zoster virus. This contagious itchy red rash covers the entire body with red blistery spots causing discomfort (Web MD 2013). Immunization, education, awareness and the epidemiology of Chicken Pox has made drastic improvement in the occurrence and mortality of disease (Centers for Disease Control and Prevention 2014). Description of Communicable Disease Chicken Pox can be easily transmitted from one person to the next by means of sneezing, coughing, saliva and surface contact (Web MD 2013). The fluid filled blisters rupture and accelerates the probability of transmission by contact. This disease is contagious 2-3 days prior to the rash appearing having an impact on how quickly this disease is transmitted due to the patient being asymptomatic (Web MD 2013). The ones who remain most at risk are those who’ve never had the disease or obtained a vaccine. The preliminary symptoms start to appear 14-16 days after contact with someone who had the disease (Web MD 2013). Symptoms include flu like symptoms with a fever, decreased appetite, headache, cough and sore throat. The itchy red spots appear taking approximately 2 days to go through the stages of blistering, bursting, drying and crusting over (Web MD 2013). Spots continue to appear everyday for about one week. It will take about one and......

Epidemiology Rsv

... Epidemiology of RSV and Community Nurse Guidance While caring for a patient a nurse needs to be aware of the current disease process and the epidemiology behind that process. If the nurse is aware of these things, then there is a chance that disease progression or transmission can be slowed or stopped before the process devastates a community. When respiratory syncytial virus (RSV) is in its most rapidly developing phase, the community health nurse is in an ideal position to educate the community on keeping children safe and free from this, at times, devastating virus. Epidemiology and Care of RSV It is important to understand the epidemiology of a disease process to effectively manage and treat the disease. Rowe (2013) notes that epidemiology “is the discipline that provides the structure for systematically studying the distribution and determinants of health, disease, and conditions related to health status” (p. 162). When the nurse is evaluating the epidemiology of a disease process such as RSV, he/she needs to keep in mind three critical concepts related to the understanding of epidemiology “the natural history of the disease, the levels of prevention, and the multiple causation of disease” (Rowe, 2013, p. 166). Respiratory Syncytial Virus (RSV) The causes, symptoms, mode of transmission, complications and treatment options are important to understand when caring for a child with RSV. The pathogenesis and causes of RSV are fairly well understood, once RSV......

...Epidemiology: HIV The Human Immunodeficiency Virus (HIV) is one of the world’s largest pandemics as well as one of the most known diseases. With HIV being so common amongst our population, in today’s world many people still lack the knowledge of what HIV really is and how it is transmitted. This paper will explain in depth of how HIV is spread and the impact it has on society. Let’s begin with the history of HIV, where did it come from? Although there is no actual evidence to support this theory scientist believed the disease came from Chimpanzee’s that were infected. Hunters would eat the contaminated meat and then they became infected. The first report of HIV contraction came from a man from Congo in 1959, but how he became HIV positive is unknown (Where did HIV come from?, 2011). In 2011 the Centers for Disease Control and Prevention reported that 49, 273 people were diagnosed with HIV in the United States. In the same year there were an estimated 1.1 million people with the disease and 1 out of 6 of those people might not know they are infected (HIV in The United States, 2011). HIV is transmitted through body fluids such as semen, pre- semen, rectal and vaginal fluids as well as through the sharing of needles. This makes the gay, lesbian and MSM population more susceptible to acquiring the disease due to their risky sexual practices (HIV Transmission, 2014). The populations of intravenous drug users are also at risk for catching HIV, many of them being homeless and......

...Epidemiology Question 1 1. Case control studies are designed in such a way so as to explore whether exposure can be associated with a particular outcome, such as a disease or certain condition. In these studies, the definition groups are based on the outcome and exposure assessment for potential risk factors. The first step in case control studies is the identification of the case (for example a group of people known to have the certain condition), as well as the control group ( a group that does not have the outcome). The second step is to explore whether some of the subjects in each group were exposed, and how the frequency of the exposure is measured between the case and the control group. Case control studies are basically observational, because there is no intervention taking place, and is a retrospective determination of the exposure to a certain risk factor. Advantages of case control studies • Case control studies are relatively less time consuming, since the disease has occurred in the past, therefore there is no need to assess the disease or condition. • They are an efficient way to study rare cases and diseases or outbreaks of diseases, since they are fast; during an outbreak, the fast examination of certain conditions is required, and a sufficient number of people suffering can be quickly accessed. • They allow a simultaneous examination of multiple conditions and risk factors • Allow the establishment of associations between suspected risk...

... Epidemiology Paper Tamika Swearingen NUR/ 408 December 1, 2014 Kimberly Oatman Epidemiology Paper The number of children diagnosed with diabetes in 2012, according to the CDC (2014), is about 208,000 people younger than 20 years in the United States alone. This includes those having been diagnosed diabetes type 1 or type 2. Diabetes has become more prevalent and there is no cure at this time. With the study of Epidemiology, there is hope for a decline of Diabetes and it dominance amongst the American children. In this paper, it will describe and define epidemiology and how it relates to diabetes. This paper will discuss the method and triangle of epidemiology along with the chosen vulnerable population and disease of diabetes in children. Definition of Epidemiology Epidemiology has been defined as “the study of the occurrence and distribution of health-related states or events in specified populations, including the study of the determinants influencing such states, and the application of this knowledge to control the health problems” (Stanhope and Lancaster, 2012). Epidemiology can be described as a study that looks at certain specifics of the excess risk a disease and the rate or incidence of how it is affected. It focuses on the study of why and how it affects certain populations. Steps and Methods of Epidemiology Diabetic information can be gathered in many ways such as analyzing: routine data, research data ad epidemiological data. In Southern Nevada, health......

Epidemiology of Mononucleosis

...Epidemiology of Mononucleosis Lori Lindner Grand Canyon University: 427V March 14, 2015 Epidemiology of Mononucleosis Infectious mononucleosis is a common clinical syndrome associated with Epstein-Barr virus (Singer-Leshinsky, 2012). Individuals infected with the Epstein-Barr virus can be asymptomatic or develop one of several infections which include infectious mononucleosis. A person with mononucleosis can be asymptomatic or symptomatic. Infectious mononucleosis is an acute and self limiting virus which is usually has no lasting side effects (Morris and Edmunds, 2002). However in some uncommon cases, infectious mononucleosis has caused neurologic and malignant complications (Marshall and Foxworth, 2012). Description of Mononucleosis Infectious mononucleosis, also known as the “kissing disease” is a highly infectious viral disease that most commonly occurs in adolescents and young adults in North America (Ilardi, 2009). Mononucleosis is transmitted by oral secretions and blood from one person to another. This is the reason for the nickname “kissing disease”. Symptoms of mononucleosis usually appear four to seven weeks after an individual has been infected. The symptoms include: constant fatigue, fever, sore throat, loss of appetite, swollen lymph nodes, headaches, sore muscles, swollen liver or spleen, skin rash and abdominal pain. Patients can present with all or a combination of these symptoms and the severity varies from no symptoms at all to......

...Epidemiology Name: Institution: Course: Tutor: Date: Abstract Descriptive epidemiology is based on two important premises which are central in the field. The first premise states that disease does not occur in isolation. Secondly, patterns of disease occurrence are placed under three important categories of person, place and time. This paper seeks to build understanding on the three areas by giving relevant examples where they are applied. Epidemiology Person In Epidemiology studies the important demographic information will include age, sex, marital status, race, ethnicity, and religion and socioeconomic status. Age is considered the most important factor and is used in analyzing trends in disease occurrence. Advancement in age may be associated with the occurrence of degenerative diseases. The elderly are also linked with several challenges. Changes marking age are shown by two important phases in life which shows greater frequency (Descriptive Epidemiology n.d). Sex as a second determinant of the person, and allows us to make references across sexes. For instance psychological studies have revealed that women cope well in the event of stress than men. Marital status is closer to this, and in epidemiology studies, it can be useful in establishing patterns of chronic diseases across genders (Descriptive Epidemiology n.d). Race and ethnicity have been used in epidemiology studies to......

Hiv Epidemiology

...HIV Epidemiology HIV Epidemiology For the epidemiology paper I chose to write about HIV. HIV is growing concern in the community and too many people are uneducated about the seriousness of this disease. HIV is terminal illness; it will eventually consume your life at some point. There are treatment options out there but being compliant with the medication regimen is crucial to the maintenance and management of this disease. HIV also known as the Human Immunodeficiency Virus; with HIV the virus replicates and attacks our immune system causing it to go haywire. With the suppression of our immune systems it puts people with HIV at a bigger risk for infection and other common illnesses. People with HIV the common cold can be very critical because their bodies are unable to fight off the virus. The virus attacks our WBC (white blood cells) and they are what are used to fight off infection. The cells that are affected the most are WBC that is called CD4+ cells. If these cells begin to malfunction then the body loses its ability defend itself against infection. HIV is spread when blood, semen, or vaginal fluids from an infected person enter another person's body, usually through sexual contact, from sharing needles when injecting drugs, or from mother to baby during birth (WebMD, 2014). When we deal with patients who have this disease we need to be sure to educate them on the importance of safe sex practices and the importance of refraining from drug use especially when......

...Epidemiology Betty Foote University of Phoenix Epidemiology: Global and Public Health NUR/408 Michelle Hogsed October 24, 2015 Epidemiology Human Papillomavirus (HPV) is a common sexually transmitted viral infection found in young women that is one of the primary causes of cervical cancer. Sexually active young women, with many different partners, are some of the highest contributors and recipients in the newly infected population. Use of physical barriers, like condoms, during sex, can lessen this transmission. HPV is divided into two groups, low risk, nononcogenic types and high-risk types that can cause cervical dysplasia and in rare cases, cancer. Vaccines provide some protection against developing diseases caused by the virus. Epidemiological studies continue to evolve moving treatment forward for better patient outcome. Education is still the most effective way to deter this behavior that contributes to the HPV infection. Epidemiology is defined as “the study of the occurrence and distribution of health-related states or events in specified populations, including the study of the determinants influencing such states, and the application of this knowledge to control the health problems.” (Stanhope & Lancaster, 2012, p. 255). With HPV, public health officials and scientists are constantly following the occurrences of viral spreading and patterns of occurrence. Development of vaccines is based on this data and sample collection. Public health......

...Epidemiology NUR 408 October5, 2015 Epidemiology Epidemiology is the basic principle of public health. According to Hilfinger Messias, McKeown, and Adams (2012, p. 255 ), “Epidemiology has been defined as the study of the occurrence and distribution of health-related states or events in specified populations, including the study of the determinants influencing such states, and the application of this knowledge to control the health problems” (Porta, 2008, p 81). The goal of epidemiology is optimal health for the entire community. It is important to remember that health does not merely mean medical treatment for specific diseases, but also assurance of available services and development and implementation of policies and programs to meet the needs of the population as a whole. Descriptive epidemiology is the study of the “association of health events to person, place, and time” (Stroup, D. & Thacker, S., 2009, p. 262). Analytical epidemiology studies the causes and risk factors of health events. In order to evaluate the health events in a population, both descriptive and analytical epidemiology are important (Stroup, D. & Thacker, S., 2009). Three categories of data sources commonly used in epidemiologic studies including surveillance data, census data, and vital records, data collected for other purposes, and epidemiologic data (Hilfinger Messias, McKeown, and Adams 2012). The epidemiological triangle is composed of three elements of disease, and......

...Epidemiology: Global and Public Health Jennifer Nurse NUR408 January 2011 Nancy Nurse, EdD, RN, PHN, LSN Epidemiology: Global and Public Health According to the Centers for Disease Control, “diabetes affects 25.8 million people, 8.3% of the U.S. population” (Center for Disease control and Prevention, 2012, par 1). Twice as many African Americans are likely to develop diabetes than Caucasian Americans. These statistics represent how serious diabetes has become for the black community. Epidemiology can focus healthcare efforts and interventions to help lower the incidence of diabetes of the African Americans. This paper will focus on the role of epidemiology in the observation of the frequency of diabetes in the morbidity and mortality of American of African decent. This paper will also include the definition and description of epidemiology, epidemiological methods, the epidemiological triangle, types of epidemiology, and prevention that is related with diabetes in the African American community. Definition and Description of Epidemiology Epidemiology is defined as, “the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to control of health problems.” (Center for Disease Control and Prevention, 2012, p. 243).

...Aleyamma John Epidemiology: Global and Public Health NUR/408 Community Emergency Preparedness and Response 20 February, 2012 Amy Reagan, MSN, RN Community Emergency Preparedness and Response This paper describes in detail the community preparedness and emergency response. Season 2, Episode 5 explains about the events that took place in the Neighborhood during the forest fire. This paper will also illustrate the problems faced in the Neighborhood during a disaster and the role of various community health services. The various community services can impact members within a community and prepare them for any emergent situation. This episode goes on to describe how the forest fire affected the lives of people within the Neighborhood as well as the health care facilities. The fire seemed to deteriorate the health of many by causing an increase in respiratory illnesses like asthma, emphysema, and exacerbate chronic obstructive pulmonary disease. Hospitals and clinics saw a rise in emphysema and asthma cases. They were experiencing a shortage of staff and beds. This stressed the entire staff at the hospital. Schools also had children developing breathing issues. A young girl named Kelsey Young was brought to the school nurse as she had shortness of breath. Violet, the school nurse found her coughing frequently, increased respiratory rate, and wheezing in her lungs. Kelsey's mother had to come pick her up from the school as she......

...Epidemiology Paper Allison Brown Nur 408 May 14, 2012 Prof. Pamela Orr Epidemiology Paper People have many health concerns and diagnosis that presents to the current public health as daunting. The first step in any medical situation regarding a person’s health is prevention that is talked among the professionals in the health community. This will be the only way to help the cycle to break that will further prevent other diseases from occurring. Using epidemiology and the epidemiology triangle diabetes in African Americans will be observed. This health concern in many communities in the United States can be prevented and helped, but information is the key to success. In this paper we will be examining the definition and description of epidemiology, the steps and methods of epidemiology, reviewing the data of the selected population. We will also be looking at the epidemiological triangle as well as various levels of prevention. Epidemiology is the study of the distribution and determinants of health-related states or events (including disease), and the application of this study to the control of diseases and other health problems. Various methods can be used to carry out epidemiological investigations: surveillance and descriptive studies can be used to study distribution; analytical studies are used to study determinants (WHO, 2012). Epidemiology is a type of science that guides our understanding of the strong points of how exposure and the relation to how it......
