Epidemiology and public health aspects of TB in india

In 2017, an estimated 10 million incident TB cases and 1.6 million TB deaths occurred, representing reductions of 1.8% and 3.9% from 2016, respectively. TB epidemiology varied by World Health Organization region. What are the implications for public health practice The epidemiologic triangle as it relates to TB Three factors, including hosts, agents, and environmental factors are a key component of infectious diseases. The interlinking relationship among the three components constitutes to what is referred to as the epidemiologic triangle (Venkatraman, Morris, & Wiselka, 2013) An Overview on Epidemiology of Tuberculosis Tuberculosis (TB) is a progressive granulomatous infectious disease caused by the gram positive, acid fast bacilli classified under the genus Mycobacterium. Tuberculosis in human is mostly by Mycobacterium tuberculosis and primarily affects lungs causing pulmonary tuberculosis. It can also affect in The World Health Organization (WHO) has recently launched a new global TB strategy for the post-2015 era aimed at ending the global TB epidemic by 2035. This strategy is based on the three pillars that emphasize patient-centred TB care and prevention, bold policies and supportive systems, and intensified research and innovation

The Epidemiologic Triad A number of models of disease causation have been proposed. Among the simplest of these is the epidemiologic triad or triangle, the traditional model for infectious disease. The triad consists of an external agent, a susceptible host, and an environment that brings the host and agent together Epidemiology is an important part of tuberculosis (TB) control efforts because the information on patterns of infection and disease can assist in identifying people or groups of people at risk for TB, understanding how the disease is transmitted, prioritizing cases, and planning appropriate use of staff and resources.

The Epidemiological Triad The best known, but most dated model of communicable disease is the Epidemiologic Triad (Figure 1). This model comprises a susceptible host (the person at risk for the disease),a disease agent (the proximate cause), and an environmental context for the interaction between host and agent Tuberculosis is a disease caused by Mycobacterium tuberculosis. Although TB is thought of as a lung disease, it can attack other parts of the body such as the spine, kidney and brain. Left untreated, TB can be fatal. It is spread through droplets in the air when an infected person coughs, sneezes or talks. Once considered eradicated, TB is. However, the cited epidemiological studies were limited by using as their outcomes the rates of M. tuberculosis infection among household contacts of individuals who had been hospitalized for treatment. It is likely that most susceptible contacts in those homes were exposed and infected before the hospital admission of the index case, or even. The Epidemiology of Tuberculosis Tuberculosis (TB) is a highly contagious disease that if not treated, can be fatal. This infection is known for initiating in the lungs, however it has the potential to affect any and all of the body. The tubercle bacillus or Mycobacterium tuberculosis is the bacterial microorganism the causes TB (Schiffman, 2010)

  1. The series consists of a total of nine modules that are separated into two courses. The first course, Modules 1-5, provides basic information on TB. The second course, Modules 6-9, provides more specific TB programmatic information. Epidemiology is the study of diseases and other health problems in groups of people
  2. Tuberculosis (TB) is an infectious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. Tuberculosis generally affects the lungs, but can also affect other parts of the body. Most infections show no symptoms, in which case it is known as latent tuberculosis. About 10% of latent infections progress to active disease which, if left untreated, kills about half of those affected
  3. Tuberculosis is the leading cause of death from a curable infectious disease.1 On the basis of results of surveys of the prevalence of infection and disease, assessments of the effectiveness of surveillance systems, and death registrations, there were an estimated 8·9 million new cases of tuberculosis in 2004, fewer than half of which were reported to public-health authorities and WHO

The epidemiology of tuberculosis varies substantially around the world. The highest rates (100/100,000 or higher) are observed in sub-Saharan Africa, India, China, and the islands of Southeast Asia and Micronesia (Figure 1). Estimates provided by USAID in 2007 for South Sudan were 228 cases per 100,000 population. In South Sudan, an estimated. • Tuberculosis (TB) in children is common wherever TB is common in adults i.e. TB endemic settings • TB is an important cause of illness and death in children in many TB endemic countries • At least 550 000 children become ill with tuberculosis (TB) each year. • Up to 80 000 HIV-uninfected children die of TB every year* EPIDEMIOLOGY PAPER: TUBERCULOSIS 4 Epidemiology Triad. The epidemiological triad is a model of infectious disease comprised of an agent, host, and an environment that is used to explain the spread of disease all through a community, to identify interventions that will prevent transmission, and to guide epidemiologic studies [ CITATION Gre191 \l 1033 ]

The Epidemiologic Triangle, sometimes referred to as the Epidemiologic Triad, is a tool that scientists use for addressing the three components that contribute to the spread of disease: an external agent, a susceptible host and an environment that brings the agent and host together. Since different diseases require different balances and. EPIDEMIOLOGY. On a worldwide scale, infectious diseases still account for about 25% of all deaths, only surpassed by cardiovascular diseases. 1 The picture, however, is dissimilar when industrialised and developing countries are compared. In Germany, for example, only 1% of all deaths are due to infectious diseases, whereas in developing countries—for example, in sub-Saharan Africa 49% of.

Epidemiology and socioeconomic factors — More than 1.7 billion people (about 25 percent of the world population) are estimated to be infected with M. tuberculosis [ 2,3 ]. The global incidence of TB peaked around 2003 and appears to be declining slowly [ 3 ] If you isolate a person with tuberculosis you are protecting other individuals by breaking the epidemiological triad between: agent and environment. Cancer can be caused by Benzene, High dose radiation or with genetic mutations. Each of these can cause cancer independently without the help of anything else Epidemiological triad of infectious diseases includes susceptible host, pathogen, and environment. It is imperative that all aspects of vertices of th Sub-Saharan Africa has continued leading in prevalence and incidence of major infectious disease killers such as HIV/AIDS, tuberculosis, and malaria Tuberculosis (TB) transmission often occurs within a household or community, leading to heterogeneous spatial patterns. However, apparent spatial clustering of TB could reflect ongoing transmission or co-location of risk factors and can vary considerably depending on the type of data available, the analysis methods employed and the dynamics of the underlying population

It will also demonstrate the epidemiology triad, the social determinants of healthcare, and the role of the nurses in addressing this disease. Description and Pathophysiology of Tuberculosis.

However, in some instances, it could also affect other parts of the body (WHO, 2016). For a bigger part of history, the disease remained fatal and killed patients TB-related sepsis is a life-threatening acute complication for which current diagnostic and management approaches are likely inadequate. Therapeutic intensification and usage of immunomodulators are areas of ongoing research. Paradoxical reaction or symptom worsening during TB treatment may benefit from corticosteroids. Despite successful cure. Globally, tuberculosis remains the most common cause of death in persons with HIV, accounting for approximately one-third of all global AIDS-related deaths. [ 39 , 44 ] The global decline in AIDS-related deaths has been attributed to the expanded availability and use of antiretroviral therapy in many regions of the world

By studying the interactions among the triad, we have the ability to show true causes and, therefore, uncover real solutions The Epidemiologic Triangle is a model that scientists have developed for studying health problems, specifically to understand infectious diseases and how they spread. The Triangle has three. When tuberculosis attacks the adrenal glands they become inefficient at producing hormones, such as cortisol, causing adrenal insufficiency. Symptoms include weakness, muscle fatigue, weight loss, nausea and vomiting. When Dr. Thomas Addison first diagnosed adrenal insufficiency, in 1849, tuberculosis was the cause of 70-90% of the cases

The Epidemiology Of Tuberculosis Health And Social Care Essa

Tuberculosis is becoming a world-wide problem. War, famine, homelessness, and a lack of medical care all contribute to the increasing incidence of tuberculosis among disadvantaged persons. Since TB is easily transmissible between persons, then the increase in TB in any segment of the population represents a threat to all segments of the population The Epidemiologic Triangle: three characteristics that are examined to study the cause(s) for disease in analytic epidemiology I host I agent I environment Host Agent Environment 13/19.
