An Overview on Epidemiology of Tuberculosi

Epidemiology and public health aspects of TB in india

Tuberculosis (TB) has affected humanity since the beginning of the recorded time and is associated with poverty, malnutrition, overcrowding, and immunosuppression. Since Koch discovered the infectious nature of the disease in 1882, knowledge about its history and physiopathology has advanced, but it RESULTS: The epidemiological factors associated with TB were being a health care worker (OR 10.1) and lower serum albumin level (OR 0.5) Tuberculosis epidemiological situation Natural history and pathogenesis Tuberculosis transmission occurs through droplet nuclei containing Mycobacterium tuberculosis, which are expelled by smear-positive pulmonary TB patients when coughing and sneezing, and remain suspended in the air. Inhalation of such aerosols may lead to infection As noted earlier, one important use of epidemiology is to identify the factors that place some members at greater risk than others. Causation. 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

Setting: The tuberculosis (TB) epidemic situation is both a public health problem and a socio-economic issue in China. Objective: To examine the effects of socio-economic development and of the TB control strategy on the TB epidemic in China. Methods: Based on the four National Epidemiological Surveys of TB and the indices of socio-economic development in China, correlation co-efficiency was. An understanding of the epidemiology of Mycobacterium tuberculosis is critical for effective control. The global burden of tuberculosis (TB), risk factors for transmission, and the epidemiology of TB in the United States will be reviewed here. The epidemiology of drug-resistant TB is discussed separately

Mycobacterium tuberculosis complex (MTBC) is the causative agent of tuberculosis. According to the World Health Organization, one-third of the world's population is infected, either latently or actively, with tuberculosis. Epidemiology is the science of public health A person who was physically close to someone with active TB disease and inhaled TB bacteria into their lungs is most likely to get TB infection. Other risk factors include smoking, prior residence in a country where TB is common, or living in a congregate setting (homeless shelters, migrant farm camps, nursing homes, prisons or jails) EPIDEMIOLOGY OF TUBERCULOSIS. Tuberculosis infection is very common in the world and the disease manifest when ever either the virulence of the organism increases or the resistance of the host goes down.it can affect any part of the body.the best method of control of tuberculosis is early diagnosis and treatment.despite international.

Risk factors for different stages of TB pathogenesis and epidemiology. Note. BCG = bacillus Calmette-Guerin; MDR = multidrug resistant; TB = tuberculosis. a TB infection and disease rates are often reported to be higher among Black Africans and Hispanics than among Whites Poverty is a powerful determinant of tuberculosis. Crowded and poorly ventilated living and working environments often associated with poverty constitute direct risk factors for tuberculosis transmission. Undernutrition is an important risk factor for developing active disease. Poverty is also associated with poor general health knowledge and a lack of empowerment to act on health knowledge. 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)

There has been a steady decline in TB incidence rates from 2000 to 2007 from 5.8 per 100,000 to 4.4 per 100,000. Question We used data released by the government to analyze the epidemiological distribution of pulmonary tuberculosis in mainland China from 2004 to 2015, in order to provide a deeper understanding of trends in the epidemiology of pulmonary tuberculosis in China and a theoretical basis to assess the effectiveness of government interventions and develop more targeted prevention and control strategies

Tuberculosis (TB) is an important public health issue worldwide. However, evidence concerning the impact of environmental factors on TB is sparse. We performed a retrospective analysis to determine the spatiotemporal trends and geographic variations of, and the factors associated with, the TB prevalence in Inner Mongolia. We performed a retrospective analysis of the epidemiology of TB Tuberculosis (abbreviated as TB) is one of the common communicable diseases in different parts of the world. This disease affects the human lungs and is characterized by the growth of tubercles (Allender, Rector, & Warner, 2013, p. 12). The cause of this communicable disease is a bacterium given the name Mycobacterium tuberculosis. Lipid and Fatty Acid Metabolism. M. tuberculosis is unique among bacterial pathogens in that it displays a wide array of complex lipids and lipoglycans on its cell surface. 21 These exclusive cell wall lipids are known to play an important role in pathogenesis; therefore, the genes responsible for their biosynthesis, degradation and transport are potential virulence factors that offer new.

There is a high burden of Tuberculosis in many countries which may be attributed to its demographic and socio-economic profile like poverty, lack of knowledge, attitude and practice, overcrowding, malnutrition, co-morbidity, etc. Adequate information on epidemiological factors is essential in formulating national policy and to redirect health. Tuberculosis (TB) is a notifiable disease in Georgia. All detected TB cases must be notified to the Ministry of Labour, Health and Social Security Centre for Medical Statistics and Information. The TB surveillance system consists of national, regional and local TB units tural factors influence many health outcomes,1,2 par-ticularly for tuberculosis (TB).3-5 gender roles, socially constructed in various settings, may affect access to TB services,6-9 detection,10-13 treatment adherence14 and outcome.15 as the success of TB control programmes is largely determined by patients' ability to self-identif To investigate the epidemiological factors associated with extra pulmonary tuberculosis (EPTB) in Kassala, Eastern Sudan.

Epidemiology of tuberculosis can be influenced by multiple not only clinical factors, but also demographical, geographical and social aspects at local or national levels, as the develop‐ ment of the country (Rodríguez-Morales AJ & Castañeda-Hernández DM 2012), currently measured by indicators such as the Human Development Index (HDI) In addition to distinguishing primary TB from reactivation disease, these molecular techniques have been used to identify risk factors for recent transmission in population-based epidemiologic studies Persons with compromised immune systems have a greater chance of the TUB becoming active and causing illness. Tuberculosis can be cured with treatment and can be prevented as well. Places where humans are in close contact are the most high risk areas. Slums, prisons and jails, or even hospitals are examples of high risk environments According to the World Health Organization, Nigeria is one of the countries with a high burden of tuberculosis (TB) worldwide. Improving the burden of TB among HIV-negative people would require comprehensive and up-to-date data to inform targeted policy actions in Nigeria. The study aimed to describe the incidence, prevalence, mortality, disability-adjusted life years (DALYs) and risk factors. Figure 1. Acid fast-bacilli in a Ziehl-Neelsen stain from a sample of a patient with pulmonary TB (400 X) (Fernández M & Dickson González SM 2007).Epidemiology of tuberculosis can be influenced by multiple not only clinical factors, but also demographical, geographical and social aspects at local or national levels, as the development of the country (Rodríguez-Morales AJ & Castañeda.

The epidemiological studies of indicate that the prevalence of tuberculosis in the United States, Sub-Saharan Africa, and Asia varies due to a number of factors. In the United States, the major predisposing factors of tuberculosis are race and HIV/AIDS TB Disease Burden. A summary of epidemiologic, demographic, and clinical characteristics of TB cases in the U.S. is provided in Table 1.Although TB incidence rates have declined from 52.6 per 100,000 in 1953 when the U.S. TB surveillance system was first implemented to current historic low rates of 2.7 per 100,000 [1, 3], several epidemiologic factors may make it challenging to meet the goal.

Understanding tuberculosis epidemiology among children and adolescents informs treatment and prevention efforts, and efforts to eliminate disparities in tuberculosis incidence and mortality. targeted testing of people with risk factors, and evaluation for tuberculosis symptoms), country of birth for parents or primary guardians of children. Pulmonary diseases due to mycobacteria cause significant morbidity and mortality to human health. In addition to tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb), recent epidemiological studies have shown the emergence of non-tuberculous mycobacteria (NTM) species in causing lung diseases in humans. Although more than 170 NTM species are present in various environmental niches. We performed a systematic review and meta-analyses of studies assessing tuberculosis (TB) patient-related risk factors for transmission of Mycobacterium tuberculosis infection.

Many studies have evaluated risk factors for death in the treatment of TB, and many factors, such as age, sex, bacteriological status, comorbidities, immune and nutritional status of host and substance abuse, have been identified [Reference Kwon 11]. However, the prognostic factor for in-hospital mortality in ICU TB patients remains unclear Overview of drug resistant Mycobacterium tuberculosis strain types in Africa Molecular epidemiological data. The molecular mechanisms of drug resistance as well as the evolution of drug resistant strains in Africa have been studied using a variety of genotyping tools [10,11,12,13].This has provided some insight into the transmission dynamics of drug resistant TB Background: Tuberculosis (TB) is one of the lethal infectious diseases in the world.One of the current biggest challenges of Tuberculosis control is the widespread emergence of Multidrug Resistant Tuberculosis (MDR-TB). There are several potential risk factors of MDR-TB that can be explained by Health Belief Model and PRECEDE PROCEED model framework

Introduction. Tuberculosis (TB) has been a serious infectious disease in developing countries, and spinal TB is the most common bone and joint TB, accounting for about 50% of cases [Reference Jin 1].Spinal TB often leads to irreversible neurological injury, including paralysis, resulting in serious social and economic problems [Reference Pigrau and Rodriguez 2] In conclusion, our study expands the knowledge base regarding the epidemiology of extrapulmonary tuberculosis and enhances understanding of the relative contribution of host-related factors to the pathogenesis of tuberculosis. To achieve a more complete understanding of the pathogenesis of tuberculosis, the role of microbial factors must be.

tuberculosis (TB) remains a major global health problem1. Only 5%-15% of individuals infected with Mycobacterium tuberculosis (Mtb) ever develop TB disease, and over 50% of these do so within two years after infection2. Although risk factors for progression to TB disease have been identified3 Health-care workers (HCWs) are an epidemiological group with increased exposure to tuberculosis (TB), especially at health-care facilities (HCFs) with poor TB infection control in high-TB-burden settings. China is a high-TB-burden country, and the comprehensive measures for stopping TB transmission at some HCFs were not implemented well owing to limited resources and other factors 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 Tuberculosis (TB) is a communicable bacterial disease caused mainly by the Mycobac - terium Tuberculosis, also known as tubercle bacilli or as acid-fast bacilli (AFB), which affects primarily the lungs. Occasionally, other species of mycobacterium could affect other parts of the body (Harries, Maher & Graham, 2004:23)

Factors that influence current tuberculosis epidemiology

1. Introduction. An understanding of the epidemiology of multidrug resistant tuberculosis (MDR-TB) and the extensively drug-resistant tuberculosis (XDR-TB) is critical for effective control of the global burden of tuberculosis (TB) which is caused by the organisms belonging to the Mycobacterium tuberculosis complex. Epidemiology of MDR-TB and XDR-TB will be reviewed here INTRODUCTION. Mycobacterium tuberculosis is an ancient human pathogen, which has plagued countless human societies despite the introduction of curative and preventive therapy in the last century [].In recent years, international attention has turned toward the evolving burden of drug resistance. Multidrug-resistant tuberculosis (MDR-TB) has emerged in epidemic proportions in the wake of. Bovine tuberculosis (bTB) is a chronic disease of cattle caused by infection with the Mycobacterium bovis.While bTB prevalence in Uruguay has been low (<11 outbreaks/year) for the past 50 years as a consequence of a national control program, annual incidence increased in 2011 through 2013-15, 26 and 16 infected herds each year, raising concerns from livestock stakeholders and the government • 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* This study was conducted to assess the incidence rate of tuberculosis, and determine the risk factors of TB infection among different occupational groups in the Makkah region, Saudi Arabia in 2016

Epidemiology is the study of disease in a population and the factors that determine its occurrence over time. It examines the distribution of disease and risk factors for infection, in order to identify opportunities for intervention. In the context of bovine TB, epidemiology reports are produced by APHA for the different regions of GB Important epidemiological changes and improvement of new diagnostic approaches, mainly molecular tools, might have impacted the management and outcome of tuberculosis (TB) in the last years in industrialized countries. In order to describe the epidemiological trends, and changes in clinical, diagnostic, and therapeutic aspects in patients with TB, an observational study was performed in a. Since 1990, characterization of Mycobacterium tuberculosis isolates by molecular methods has been useful in confirming suspected laboratory contamination and as an adjunct to epidemiology-based contact investigation (1-3).Most studies used the restriction fragment length polymorphism (RFLP) technique, s based on IS6110 and specific to the M. tuberculosis complex •Indiana TB case count decreased in 2019. • -6.9% change •The number of TB deaths in Indiana has decreased for the first time in four years. •Proportion of U.S.-born cases decreased. • This trend matches national data. •Risk Factors: Non-injection drug use and diabetes are increasing. •Continued success in TB treatment and case. Tuberculosis is a severe infectious disease caused by the bacterium Mycobacterium tuberculosis which mainly affects the lungs (CDC, 2015). 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
