Roadmap to Prevent and Combat Drug-Resistant Tuberculosis
Roadmap to prevent and combat drug-resistant tuberculosis ROADMAP TO PREVENT AND COMBAT DRUG-RESISTANT TUBERCULOSIS The Consolidated Action Plan to Prevent and Combat Multidrug- and Extensively Drug-Resistant Tuberculosis in the WHO European Region, 2011-2015 Abstract In response to the alarming problem of multidrug- and extensively drug-resistant tuberculosis (M/XDR-TB) in the WHO European Region, and in order to scale up a comprehensive response and to prevent and control M/XDR-TB, a consolidated action plan has been developed for 2011–2015 for all 53 Member States of the WHO European Region and partners. The Plan was endorsed by the sixty-first session of the WHO Regional Committee in Baku on 15 September 2011. It has six stra- tegic directions and seven areas of intervention. The strategic directions are cross-cutting and highlight the corporate priori- ties of the Region. The areas of intervention are aligned with the Global Plan to Stop TB 2011–2015 and include the same targets as set by the Global Plan and World Health Assembly resolution WHA62.15, to provide universal access to diagnosis and treatment of MDR-TB. The implementation of the Consolidated Action Plan would mean that the emergence of 250 000 new MDR-TB patients and 13 000 XDR-TB patients would be averted, an estimated 225 000 MDR-TB patients would be diagnosed and at least 127 000 of them would be successfully treated thus interrupting the transmission of M/XDR-TB, and 120 000 lives would be saved. The cost of implementing the Plan is estimated at US$ 5.2 billion. -

Tuberculosis Diagnosis Xpert MTB/Rif®
Tuberculosis Diagnosis Xpert MTB/Rif® Xpert MTB/Rif®: New technology to diagnose TB and rifampicin resistance Fully automated molecular test. It simultaneously detects Mycobacterium tuberculosis and rifampicin resistance. Results in less than two hours from sample reception, allows health personnel to prescribe proper treatment on the same day. It has minimal bio-safety and training requirements for laboratory staff. The test benefits outweigh its cost: early diagnosis allowing adequate treatment (shortens the transmission, reduces the risk of death and provides equity in diagnosis).

Background Epidemiology of Tuberculosis in the United States Although the incidence of tuberculosis in the United States has substantially decreased since the early 1990s (Figure 1), tuberculosis continues to occur at a significant rate among certain populations, including persons from tuberculosis-endemic settings, individual in correctional facilities, persons experiencing homelessness, persons who use drugs, and individuals with HIV.[1,2] In recent years, the majority of tuberculosis cases in the United States were among the persons who were non-U.S.-born (71% in 2019), with an incidence rate approximately 16 times higher than among persons born in the United States (Figure 2).[2] Cases of tuberculosis in the United States have occurred at higher rates among persons who are Asian, Hispanic/Latino, or Black/African American (Figure 3).[1,2] In the general United States population, the prevalence of latent tuberculosis infection (LTBI) is estimated between 3.4 to 5.8%, based on the 2011 and 2012 National Health and Nutrition Examination Survey (NHANES).[3,4] Another study estimated LTBI prevalence within the United States at 3.1%, which corresponds to 8.9 million persons -

Individuals infected with Mycobacterium tuberculosis (Mtb) may develop symptoms and signs of disease (tuber- culosis disease) or may have no clinical evidence of disease (latent tuberculosis infection [LTBI]). Tuberculosis disease is a leading cause of infectious disease morbidity and mortality worldwide, yet many questions related to its diagnosis remain. -

TB Policies in 24 Countries a Survey of Diagnostic and Treatment Practices About Médecins Sans Frontières
Out of Step 2015 TB Policies in 24 Countries A survey of diagnostic and treatment practices About Médecins Sans Frontières Médecins Sans Frontières (MSF) is an independent international medical humanitarian organisation that delivers medical care to people affected by armed conflicts, epidemics, natural disasters and exclusion from healthcare. Founded in 1971, MSF has operations in over 60 countries today. MSF has been involved in TB care for 30 years, often working alongside national health authorities to treat patients in a wide variety of settings, including chronic conflict zones, urban slums, prisons, refugee camps and rural areas. MSF’s first programmes to treat multidrug-resistant TB opened in 1999, and the organisation is now one of the largest NGO treatment providers for drug-resistant TB. In 2014, the organisation started 21,500 patients on first-line TB treatment across projects in more than 20 countries, with 1,800 patients on treatment for drug-resistant TB. About the MSF Access Campaign In 1999, on the heels of MSF being awarded the Nobel Peace Prize – and largely in response to the inequalities surrounding access to HIV/AIDS treatment between rich and poor countries – MSF launched the Access Campaign. Its sole purpose has been to push for access to, and the development of, life- saving and life-prolonging medicines, diagnostics and vaccines for patients in MSF programmes and beyond. About Stop TB Partnership The Stop TB Partnership is leading the way to a world without TB, a disease that is curable but still kills three people every minute. Founded in 2001, the Partnership’s mission is to serve every person who is vulnerable to TB and to ensure that high-quality treatment is available to all who need it. -

Health Care Provider Information NOTE: This page is a resource for Whatcom County clinicians dealing with tuberculosis: recognizing active disease and screening for and treating latent infection. The Whatcom County Health Department provides this as a tool/resource in our collaboration with community clinicians, and we welcome feedback and suggestions for additions and changes that improve its usefulness. (Contact Info) Distinguishing Active TB Disease from Latent Infection TB life cycle/Transmission: Tuberculosis (TB) is a disease caused by bacteria (Mycobacteria tuberculosis, or Mtb) transmitted from people with active pulmonary or laryngeal TB disease as aerosolized particles that are suspended in air. Other people may inhale these infectious particles and become infected with Mtb. In the vast majority of cases, their immune system responds to the infection and walls it off, resulting in a latent tuberculosis infection with no disease (and not contagious). When the infected person is immunosuppressed (e.g., HIV/AIDS) or has an immature immune system (young child), the infection may progress to primary active disease without latency. Immune response: The asymptomatic, noncontagious cases are identified by measuring their immune response to tuberculosis, using a TB skin test (TST) or a blood test (interferon gamma release assay, or IGRA). Progression to disease: About 5% of those with latent infection progress to active tuberculosis disease in the first two years after becoming infected. The risk for progression after that is about 0.1% per year (1% per decade of remaining lifetime). The risk of progression increases with conditions that suppress the immune system. This progression can occur with initial infection (primary disease) or after a latent period (reactivation disease).
