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
Between 2011 and 2019, WHO has developed and issued evidence-based policy recommendations on the treatment and care of patients with DR-TB. These policy recommendations have been presented in several WHO documents and their associated annexes, including the WHO Consolidated Guidelines on Drug Resistant Tuberculosis Treatment, issued by WHO in March 2019. The policy recommendations in each of these guidelines have been developed by WHO-convened Guideline Development Groups, using the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach to summarize the evidence, and formulate policy recommendations and accompanying remarks. The present WHO Consolidated Guidelines on Tuberculosis, Module 4: Treatment - Drug-Resistant Tuberculosis Treatment includes a comprehensive set of WHO recommendations for the treatment and care of DR-TB. The document includes two new recommendations, one on the composition of shorter regimens and one on the use of the BPaL regimen (i.e. bedaquiline, pretomanid and linezolid). In addition, the consolidated guidelines include existing recommendations on treatment regimens for isoniazid-resistant TB and MDR/RR-TB, including longer regimens, culture monitoring of patients on treatment, the timing of antiretroviral therapy (ART) in MDR/RR-TB patients infected with the human immunodeficiency virus (HIV), the use of surgery for patients receiving MDR-TB treatment, and optimal models of patient support and care. The guidelines are to be used primarily in national TB programmes, or their equivalents in Ministries of Health, and for other policy-makers and technical organizations working on TB and infectious diseases in public and private sectors and in the community.

Book Description
The political declaration of the first United Nations (UN) high-level meeting on tuberculosis (TB) calls countries to diagnose and treat 40 million people with TB globally between 2018 and 2022. Traditionally, in most countries, TB diagnosis has been performed using sputum-smear microscopy, a method developed more than 100 years ago, with suboptimal sensitivity. In recent years new technologies have emerged based on the detection of mycobacterial DNA or mycobacterial antigens. Over the past decade the World Health Organization (WHO) has published a number of guidelines developed by WHO-convened Guideline Development Groups (GDGs), using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to summarize the evidence and to formulate policy recommendations and accompanying remarks. The present document "WHO consolidated guidelines on tuberculosis. Module 3: Diagnosis - Rapid diagnostics for tuberculosis detection" consolidates five guidelines developed by WHO between 2016 and 2020. Earlier guidelines on diagnostics that were not developed according to the GRADE approach have not been included in this document. The WHO Consolidated Guidelines on Tuberculosis will group all TB recommendations in one document and will be complemented by matching modules of an operational handbook. The handbook will provide practical advice on how to put in place the recommendations at the scale needed to achieve national and global impact. A range of new diagnostic technologies have been endorsed by WHO during the past decade. These are listed below: - real-time polymerase chain reaction (PCR) assays - for example, Xpert MTB/RIF(r) (Ultra) (cartridge-based) and TruenatTM (chip-based);- line probe assays (LPAs) - for example, GenoType(r) MTBDRplus v1 and v2, GenoscholarTM NTM+MDRTB II and GenoType(r) MTBDRsl;- loop-mediated isothermal amplification (LAMP) - for example, TB-LAMP; and- antigen detection in a lateral flow format (biomarker-based detection) - for example, Alere DetermineTM TB LAM Ag. The present "WHO consolidated guidelines on tuberculosis. Module 3: Diagnosis - Rapid diagnostics for tuberculosis detection" provides background, justification and recommendations on these technologies. The document includes new recommendations on molecular assays intended as initial tests for the diagnosis of pulmonary and extrapulmonary TB and rifampicin resistance in adults and children.

Book Description
Tuberculosis (TB) strains with drug resistance (DR-TB) are more difficult to treat than drug-susceptible ones, and threaten global progress towards the targets set by the End TB Strategy of the World Health Organization (WHO). There is thus a critical need for evidence-based policy recommendations on the treatment and care of patients with DR-TB, based on the most recent and comprehensive evidence available. In this regard, the WHO consolidated guidelines on drug-resistant tuberculosis treatment fulfil the mandate of WHO to inform health professionals in Member States on how to improve treatment and care for patients with DR-TB. Between 2011 and 2018, WHO has developed and issued evidence-based policy recommendations on the treatment and care of patients with DR-TB. These policy recommendations have been presented in several WHO documents and their associated annexes, including the WHO treatment guidelines for multidrug- and rifampicin-resistant tuberculosis, 2018 update, issued by WHO in December 2018. The policy recommendations in each of these guidelines have been developed by WHO-convened Guideline Development Groups (GDGs), using the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach to summarize the evidence, and formulate policy recommendations and accompanying remarks. The present Consolidated guidelines include a comprehensive set of WHO recommendations for the treatment and care of DR-TB, derived from these WHO guidelines documents. The consolidated guidelines include policy recommendations on treatment regimens for isoniazid-resistant TB (Hr-TB) and MDR/RR-TB, including longer and shorter regimens, culture monitoring of patients on treatment, the timing of antiretroviral therapy (ART) in MDR/RR-TB patients infected with the human immunodeficiency virus (HIV), use of surgery for patients receiving MDR-TB treatment, and optimal models of patient support and care.

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 first version of the WHO Malaria microscopy quality assurance manual (2009) was based on recommendations made at a series of informal consultations organized by WHO particularly a bi-regional meeting of the WHO regional offices for South-East Asia and the Western Pacific in April 2005 in Kuala Lumpur Malaysia followed by informal consultations held in March 2006 and February 2008 in Geneva Switzerland. Subsequently extensive consultations among international malaria experts led to consensus and preparation of the manual. This second version of the Manual is based on the recommendations of experts made at a WHO technical consultation in March 2014 in Geneva Switzerland. The aim of the meeting was to review the experiences of national malaria control programmes (NMCPs) national reference laboratories (NRLs) and technical agencies in using the Manual and country experience in order to improve systems for managing the quality of malaria microscopy. This second version takes into account the many years of experience of several agencies in the various aspects of quality assurance (QA) described in the Manual. In particular the sections on assessment of competence in malaria microscopy are based on use of this method by the WHO regional offices for South-East Asia and the Western Pacific in collaboration with the WHO Coordinating Centre for Malaria in Australia and by the WHO Regional Office for Africa in collaboration with Amref Health Africa. The section on setting up and managing an international reference malaria slide bank is based on the work of the WHO Regional Office for the Western Pacific in collaboration with the WHO Coordinating Centre for Malaria Diagnosis in the Philippines. The section on proficiency testing for malaria microscopy is based on work in the WHO Regional Office for Africa in collaboration with the National Institute for Communicable Diseases in South Africa and experience in regional initiatives by Amref Health Africa. The section on slide validation is based on work by Médecins sans Frontières and the section on outreach training and supportive supervision (OTSS) is based on work by the President's Malaria Initiative Malaria Care Project Medical Care Development International and Amref Health Africa. The Manual is designed primarily to assist managers of NMCPs and general laboratory services responsible for malaria control. The information is also applicable to nongovernmental organizations (NGOs) and funding agencies involved in improving quality management systems for malaria microscopy. The Manual is not designed for QA of microscopy in research situations such as in clinical trials of new drugs and vaccines or for monitoring parasite drug resistance. It forms part of a series of WHO documents designed to assist countries in improving the quality of malaria diagnosis in clinical settings including the revised training manuals on Basic malaria microscopy (2010) and the Bench aids for malaria microscopy (2010).

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.
