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
Infectious diseases are the leading cause of death globally, particularly among children and young adults. The spread of new pathogens and the threat of antimicrobial resistance pose particular challenges in combating these diseases. Major Infectious Diseases identifies feasible, cost-effective packages of interventions and strategies across delivery platforms to prevent and treat HIV/AIDS, other sexually transmitted infections, tuberculosis, malaria, adult febrile illness, viral hepatitis, and neglected tropical diseases. The volume emphasizes the need to effectively address emerging antimicrobial resistance, strengthen health systems, and increase access to care. The attainable goals are to reduce incidence, develop innovative approaches, and optimize existing tools in resource-constrained settings.

Book Description
This 2011 update of Guidelines for the programmatic management of drug-resistant tuberculosis is intended as a tool for use by public health professionals working in response to the Sixty-second World Health Assembly's resolution on prevention and control of multidrug-resistant tuberculosis and extensively drug-resistant tuberculosis. Resolution WHA62.15, adopted in 2009, calls on Member States to develop a comprehensive framework for the management and care of patients with drug-resistant TB. The recommendations contained in these guidelines address the most topical questions concerning the programmatic management of drug-resistant TB: case-finding, multidrug resistance, treatment regimens, monitoring the response to treatment, and selecting models of care. The guidelines primarily target staff and medical practitioners working in TB treatment and control, and partners and organizations providing technical and financial support for care of drug-resistant TB in settings where resources are limited.

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
Getting the right diagnosis is a key aspect of health care - it provides an explanation of a patient's health problem and informs subsequent health care decisions. The diagnostic process is a complex, collaborative activity that involves clinical reasoning and information gathering to determine a patient's health problem. According to Improving Diagnosis in Health Care, diagnostic errors-inaccurate or delayed diagnoses-persist throughout all settings of care and continue to harm an unacceptable number of patients. It is likely that most people will experience at least one diagnostic error in their lifetime, sometimes with devastating consequences. Diagnostic errors may cause harm to patients by preventing or delaying appropriate treatment, providing unnecessary or harmful treatment, or resulting in psychological or financial repercussions. The committee concluded that improving the diagnostic process is not only possible, but also represents a moral, professional, and public health imperative. Improving Diagnosis in Health Care, a continuation of the landmark Institute of Medicine reports To Err Is Human (2000) and Crossing the Quality Chasm (2001), finds that diagnosis-and, in particular, the occurrence of diagnostic errorsâ€"has been largely unappreciated in efforts to improve the quality and safety of health care. Without a dedicated focus on improving diagnosis, diagnostic errors will likely worsen as the delivery of health care and the diagnostic process continue to increase in complexity. Just as the diagnostic process is a collaborative activity, improving diagnosis will require collaboration and a widespread commitment to change among health care professionals, health care organizations, patients and their families, researchers, and policy makers. The recommendations of Improving Diagnosis in Health Care contribute to the growing momentum for change in this crucial area of health care quality and safety.

Book Description
Between 2007 and the end of 2016, 24 countries implemented a total of 25 national tuberculosis prevalence surveys using methods recommended by WHO. The 25 surveys consisted of 13 in Asia and 12 in Africa. Collectively, survey findings have informed the policies, plans and programmatic actions needed to address gaps in TB diagnosis and treatment and to reduce the burden of TB disease. Finally, the 24 countries have a robust baseline for assessing progress towards new global targets set in the UN Sustainable Development Goals (2016–2030) and WHO’s End TB Strategy (2016–2035). The methods, results, successes achieved, challenges faced and lessons learned from the 25 surveys were comprehensively documented in the book. We viewed such a product as a global public good, that should be available to all those with an interest in and commitment to using survey findings, now and in the future e.g. academics, donors, public health officers and national TB programmes. As with implementation of the 25 surveys themselves, the book is the result of a major global, regional and national collaborative and collective effort, with more than 450 contributors from all around the world.

Book Description
Every year there are 8.8 million new active cases and nearly two million deaths worldwide from tuberculosis (about 5,000 every day), mostly in the poorest communities of the developing world. One third of the world's population has latent TB which may later develop into an active form of the disease, and it has also become the leading cause of death among people with HIV. Multidrug-resistance is also a growing problem. A key challenge for the public health community is to be able to effectively diagnose patients so that valuable resources and medicines are not wasted on misdiagnosis and repeat treatments. This report, written by an international network of researchers and policy experts, examines the global market for TB diagnostics available for active disease, latent infection, drug resistance and treatment response. It provides a sound basis for diagnostics development suitable for various levels of health systems in industrialised and developing countries.

Book Description
WHO has published a global TB report every year since 1997. The main aim of the report is to provide a comprehensive and up-to-date assessment of the TB epidemic, and of progress in prevention, diagnosis and treatment of the disease, at global, regional and country levels. This is done in the context of recommended global TB strategies and targets endorsed by WHO?s Member States, broader development goals set by the United Nations (UN) and targets set in the political declaration at the first UN high-level meeting on TB (held in September 2018). The 2019 edition of the global TB report was released on 17 October 2019. The data in this report are updated annually. Please note that direct comparisons between estimates of TB disease burden in the latest report and previous reports are not appropriate. The most recent time-series of estimates are published in the 2019 global TB report.
