Book Description
There have been calls to revisit the experiences of TB screening campaigns that were widely applied in Europe and North America in the mid-20th century, as well as more recent experiences with TB screening in countries with a high burden of the disease, and to assess their possible relevance for TB care and prevention in the 21st century. In response, WHO has developed guidelines on screening for active TB. An extensive review of the evidence has been undertaken. The review suggests that screening, if done in the right way and targeting the right people, may reduce suffering and death, but the review also highlights several reasons to be cautious. As discussed in detail in this book, there is a need to balance potential benefits against the risks and costs of screening; this conclusion is mirrored by the history of TB screening. This publication presents the first comprehensive assessment by WHO of the appropriateness of screening for active TB since the recommendations made in 1974 by the Expert Committee. However, the relative effectiveness and cost effectiveness of screening remain uncertain, a point that is underscored by the systematic reviews presented in this guideline. Evidence suggests that some risk groups should always be screened, whereas the prioritization of other risk groups as well as the choice of screening approach depend on the epidemiology, the health-system context, and the resources available. This book sets out basic principles for prioritizing risk groups and choosing a screening approach; it also emphasizes the importance of assessing the epidemiological situation, adapting approaches to local situations, integrating TB screening into other health-promotion activities, minimizing the risk of harm to individuals, and engaging in continual monitoring and evaluation. It calls for more and better research to assess the impact of screening and to develop and evaluate new screening tests and approaches.

Book Description
The WHO consolidated guidelines on tuberculosis. Module 2: screening – systematic screening for tuberculosis disease is an updated and consolidated summary of WHO recommendations on systematic screening for tuberculosis (TB) disease, containing 17 recommendations for populations in which TB screening should be conducted and tools to be used for TB screening. TB screening is strongly recommendations for household and close contacts of individuals with TB, people living with HIV, miners exposed to silica dust, and prisoners. In addition, screening is conditionally recommended for people with risk factors for TB attending health care, and for communities with risk factors for TB and limited access to care (e.g. homeless, urban poor, refugees, migrants). General population screening is recommended in high-burden settings (0.5% prevalence or higher). Symptoms, chest radiography (CXR), and molecular WHO-recommended rapid diagnostic tests for TB are recommended as screening tools for all adults eligible for screening. Computer-aided detection programmes are recommended as alternatives to human interpretation of CXR in settings where trained personnel are scarce. For people living with HIV, C-reactive protein is also a good screening tool. This guideline document is accompanied by an operational handbook, the WHO operational handbook on tuberculosis. Module 2: screening – systematic screening for tuberculosis disease, that presents principles of screening, steps in planning and implementing a screening programme, and algorithm options for screening different populations.

Book Description
BACKGROUND: Latent tuberculosis infection (LTBI), defined as a state of persistent immune response to prior-acquired Mycobacterium tuberculosis antigens without evidence of clinically manifested active TB, affects about one-third of the world's population. Approximately 10% of people with LTBI will develop active TB disease in their lifetime, with the majority developing it within the first five years after initial infection. Currently available treatments have an efficacy ranging from 60% to 90%. Systematic testing and treatment of LTBI in at-risk populations is a critical component of WHO's eight-point framework adapted from the End TB Strategy to target pre-elimination and, ultimately, elimination in low incidence countries. OVERVIEW: Recognizing the importance of expanding the response to LTBI, in 2014 WHO developed Guidelines on the Management of Latent Tuberculosis Infection. The guidelines are primarily targeted at high-income or upper middle-income countries with an estimated TB incidence rate of less than 100 per 100 000 population, because they are most likely to benefit from it due to their current TB epidemiology and resource availability. The overall objective of the guidelines is to provide public health approach guidance on evidence-based practices for testing, treating and managing LTBI in individuals with the highest risk of progression to active disease. Specific objectives include identifying and prioritizing at-risk population groups for targeted intervention of LTBI testing and treatment, including defining an algorithm, and recommending specific treatment options. The guidelines are expected to provide the basis and rationale for the development of national guidelines for LTBI management based on available resources, epidemiology of TB including intensity of transmission, the health-care delivery system of the country, and other national and local determinants.

Book Description
"More than one third of the 9 million people who fall ill with tuberculosis (TB) each year are not diagnosed, not notified, or do not start treatment. Many of those who do start treatment have a delayed start due to a range of challenges. Such obstacles to receive care can result in poor health outcomes for the affected individuals, catastrophic costs for their families and continued transmission of TB to others in their communities. In addition, the individuals and communities at highest risk of falling ill with TB are often those with the least access to health care and treatment for the disease, further compounding the negative effects of the disease. These barriers to care, coupled with the magnitude and persistence of the global TB burden, argue for a redoubling of efforts to ensure early identification of and treatment for all people with TB. To this end, the systematic screening of those at high risk for TB is a key component of the World Health Organization's (WHO) End TB strategy, 2016 to 2035. Like all case-finding strategies, systematic screening for TB has three primary goals: 1. to ensure the early detection and initiation of appropriate treatment for those with active TB; 2. to reduce the risk of poor treatment outcomes, health sequelae and the adverse social and economic consequences of TB; and 3. to reduce transmission of TB, with the ultimate goal of reducing future incidence. The WHO has published guidelines that set out the principles for screening for active TB and provide recommendations on prioritizing of risk groups and choosing a screening approach.6 Screening should not be done on a mass, indiscriminate scale because this is expensive, of relatively low benefit and can result in many false positive results. One of the key principles set out in the guidelines is that screening for TB needs to be properly targeted to high-risk groups and tailored to each specific situation, depending on the epidemiological, social and health-systems contexts. This document provides practical guidance on translating WHO's principles and recommendations into a national or local screening strategy by: 1. assessing the situation; 2. defining the objectives of screening; 3. prioritizing risk groups for screening; 4. choosing screening tools, algorithms and approaches for each risk group; 5. planning and budgeting for, and implementing the strategy; 6. monitoring and evaluating the strategy. The guide includes a description of a web-based tool that can be used to help identify and prioritize risk groups and chose appropriate screening and diagnostic algorithms. The tool is designed to assist with the initial planning stages of creating a targeted screening strategy, but several other factors than those covered by the tool need to be considered in the planning process. This guide also includes additional online material, including other tools and references to assist with planning and implementing screening programmes."--Page 4

Book Description
A comprehensive resource describing innovative technologies and digital health tools that can revolutionize the delivery of health care in low- to middle-income countries, particularly in remote rural impoverished communities Revolutionizing Tropical Medicine offers an up-to-date guide for healthcare and other professionals working in low-resource countries where access to health care facilities for diagnosis and treatment is challenging. Rather than suggesting the expensive solution of building new bricks and mortar clinics and hospitals and increasing the number of doctors and nurses in these deprived areas, the authors propose a complete change of mindset. They outline a number of ideas for improving healthcare including rapid diagnostic testing for infectious and non-infectious diseases at a point-of-care facility, together with low cost portable imaging devices. In addition, the authors recommend a change in the way in which health care is delivered. This approach requires task-shifting within the healthcare provision system so that nurses, laboratory technicians, pharmacists and others are trained in the newly available technologies, thus enabling faster and more appropriate triage for people requiring medical treatment. This text: Describes the current burden of communicable and non-communicable diseases in low- to middle-income countries throughout the world Describes the major advances in healthcare outcomes in low-to middle-income countries derived from implementation of the United Nations/World Health Organisation’s 2000 Millennium Development Goals Provides a review of inexpensive rapid diagnostic point-of-care tests for infectious diseases in low-resource countries, particularly for people living in remote rural areas Provides a review of other rapid point-of-care services for assessing hematological function, biochemical function, renal function, hepatic function and status including hepatitis, acid-base balance, sickle cell disease, severe acute malnutrition and spirometry Explores the use of low-cost portable imaging devices for use in remote rural areas including a novel method of examining the optic fundus using a smartphone and the extensive value of portable ultrasound scanning when x-ray facilities are not available Describes the use of telemedicine in the clinical management of both children and adults in remote rural settings Looks to the future of clinical management in remote impoverished rural settings using nucleic acid identification of pathogens, the use of nanoparticles for water purification, the use of drones, the use of pulse oximetry and the use of near-infrared spectroscopy Finally, it assesses the potential for future healthcare improvement in impoverished areas and how the United Nations/World Health Organization 2015 Sustainable Development Goals are approaching this. Written for physicians, infectious disease specialists, pathologists, radiologists, nurses, pharmacists and other health care workers, as well as government healthcare managers, Revolutionizing Tropical Medicine is a new up-to-date essential and realistic guide to treating and diagnosing patients in low-resource tropical countries based on new technologies.

Book Description
"Given the absence of international guidelines on the joint management and control of TB and diabetes, the World Health Organization (WHO) and the International Union Against Tuberculosis and Lung Disease (the Union) identified key questions to be answered and commissioned systematic reviews of studies addressing those questions. A series of expert consultations were organized to assess the findings of the systematic reviews and a guideline group was established to develop this provisional collaborative framework. The framework aims to guide national programmes, clinicians and others engaged in care of patients and prevention and control of diabetes and TB on how to establish a coordinated response to both diseases, at organizational and clinical levels. The framework is based on evidence collated from systematic reviews and existing guidelines on the diagnosis and management of TB and diabetes. The systematic reviews confirmed the weak evidence base for the effectiveness and cost-effectiveness of collaborative interventions. The framework is therefore provisional; several of its recommendations are provisional pending better evidence. In order to provide advice on how to fill the knowledge gaps, the framework includes a list of priority research areas."--Page vii-viii.

Book Description
The main purpose of these recommendations is to assist national and local public health tuberculosis (TB) control programmes in low- and middle-income countries to develop and implement case finding among people exposed to infectious cases of TB. Systematic evaluation of people who have been exposed to potentially infectious cases of tuberculosis (TB) can be an efficient, targeted approach to intensified TB case finding that is within the purview of TB control programmes. There are, however, no comprehensive global recommendations for programmes. WHO, the International Union against Tuberculosis and Lung Disease and the International Standards for Tuberculosis Care all recommend that children under 5 years of age and persons living with HIV (PLHIV) who are exposed to infectious cases of TB be evaluated for active TB and considered for treatment of latent tuberculosis infection (LTBI) if active TB is excluded. With these exceptions, there are no recommendations at global level to: 1. define the epidemiological and programme conditions under which contact investigation is indicated;2. describe TB index patients on whom contact investigation should be focused;3. identify TB contacts who should be investigated (other than children under 5 years of age and PLHIV);and recommend the procedures to be used for identifying, screening and tracking TB contacts. The following recommendations are based on recent systematic reviews of the literature on contact investigation in low- and middle-income countries.
