El agente etiológico de la tuberculosis es el Mycobacterium tuberculosis o bacilo de Koch. Se trata de un bacilo aerobio estricto, ácido-alcohol resistente, sin movilidad, de crecimiento lento y que se inactiva con rayos ultravioleta y temperaturas mayores de 60°C.
This report has been developed, based on data provided by the TB & ORD surveillance system from across Rwanda. It provides a comprehensive picture of the occurrence and management of TB & ORD and Leprosy in Rwanda. It is structured based on the 2013-2018 Rwanda TB national strategic plan (2013-2018 ...TB NSP) and on the 2014-2018 Rwanda Leprosy national strategic plan (2014-2018 Leprosy NSP).

This publication is an updated version of the Management of Tuberculosis and HIV Coinfection clinical protocol released in 2007 by the WHO Regional Office for Europe. It is intended for all health care workers involved in preventing, diagnosing, treating and caring for people living with TB and HIV ...in the specific settings of the WHO European Region.

Three classess of tests are now recommended in the latest consolidated guideles on tests for tuberculosis infection. It includes for the first-time a new class of Mycobacterium tuberculosis antigen-based skin tests (TBSTs), and the two existing classes of tests: the tuberculin skin test (TST) and t...he interferon-gamma release assays (IGRAs).
IGRAs and TBSTs use Mycobacterium tuberculosis complex specific antigens and represent a significant advancement to TST which has been used for over half a century.

The Practical manual on laboratory strengthening, 2022 update provides practical guidance on implementation of WHO recommendations and best practices for TB laboratory strengthening. It is an updated version of the GLI Practical Guide to Laboratory Strengthening published in 2017 and provides the la...test practical guidance on use of newly recommended diagnostics as well as guidance in key technical areas, including quality assurance and quality management systems, specimen collection and registration, procurement and supply-chain management, diagnostic connectivity, biosafety, data management, human resources, strategic planning, and model algorithms. The key changes are:
inclusion of recent or updated WHO recommendations for tests to diagnose TB and detect drug resistance;
alignment with the latest WHO critical concentrations for phenotypic drug-susceptibility testing (DST) and the new definitions of pre-XDR-TB and XDR-TB;
updated information on building quality-assured TB testing and management capacity using the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) approach (Score-TB package1);
updated information on assessing, analysing and optimising TB diagnostic networks; and
updated information on the use of next-generation sequencing (NGS) to detect mutations associated with drug resistance for surveillance purposes.
The document also provides references to resources and tools relevant for work on laboratory strengthening.

Screening programmes for tuberculosis (TB) among immigrants rarely consider the heterogeneity of
risk related to migrants’ country of origin. We assess the performance of a large screening programme in asylum seekers by analysing (i) the difference in yield and numbers needed to screen (NNS) by c...ountry and WHO-reported TB burden, (ii) the possible impact of screening thresholds on sensitivity, and (iii) the value of WHO-estimated TB burden to improve the prediction accuracy of screening yield.

This handbook builds on lessons learned from surveys implemented 2015-2017 and advice provided by the Global task force on TB patient cost surveys. It provides a standardized methodology for conducting health facility-based cross-sectional surveys to assess the direct and indirect costs incurred by ...TB patients and their households. In addition, it provides recommendations on results dissemination, engaging across sectors in policy dialogue and enabling action and related research for effective modifications in care delivery models, in patient support, and wider cross-sectoral interventions.

Tuberculosis (TB) is the leading cause of death from a single infectious agent even if is largely curable and
preventable. In 2019 an estimated 2.9 million of the 10 million people who fell ill with TB were not
diagnosed or reported to the World Health Organization1. The Politi...cal Declaration adopted by the United
Nations General Assembly in September 2018 commits, amongst others, to diagnosing and treating 40
million people with TB. In order to achieve these ambitious targets, there is an urgent need to deploy
strategies to improve diagnosis and initiation of care for people with TB. One of them is systematic
screening for TB disease, which is included in the End TB Strategy as a central component of its first pillar
to ensure early diagnosis for all with TB.

Colombia has an underreporting of 30% of the total cases, according to World Health Organization (WHO) estimations. In 2016, successful tuberculosis (TB) treatment rate was 70%, and t...he mortality rate ranged between 3.5% and 10%. In 2015, Colombia adopted and adapted the End TB strategy and set a target of 50% reduction in incidence and mortality by 2035 compared with 2015.

The mandate of the National Tuberculosis Control Programme is to provide leadership and stewardship to accelerate intense and coordinated efforts to reduce the adult TB burden of 290 per 100,000 population recently established in the 2013 National TB Prevalence Survey. Other key challenges are low T...B case notification, unacceptably high TB death rates, low antiretroviral therapy (ART) coverage among TB/HIV patients and low drug-resistant notification and treatment.
