Oct 29, 2024 · Overview. Tuberculosis (TB) is an infectious disease caused by bacteria that most often affects the lungs. It spreads through the air when people with TB cough, sneeze or spit. Tuberculosis is preventable and curable. About a quarter of the global population is estimated to have been infected with TB bacteria.
Tuberculosis (TB) is the world’s top infectious killer. Nearly 4500 people lose their lives and 30 000 people fall ill with TB each day. TB is contagious and airborne. It is caused by bacteria (Mycobacterium tuberculosis) that most often affect the lungs. TB is spread from person to person through the air. When people with lung TB cough, sneeze or spit, they propel TB germs into the air. A person needs to inhale only a few of these germs to become infected.About one-quarter of the world's ...

Jun 25, 2021 · Of the 10 million people estimated to have fallen ill with tuberculosis (TB) in 2019, nearly half million developed TB resistant to rifampicin (RIF), and over one million developed TB susceptible to RIF but resistant to isoniazid (INH). Drug resistance must be detected rapidly and accurately to initiate appropriate and effective treatment.
In June 2021, WHO released a catalogue of Mycobacterium tuberculosis mutations as a reference standard for the interpretation of mutations conferring resistance to all first-line and a variety of second-line TB drugs (5). The report summarises the analysis of over 38,000 isolates with matched data on whole genome sequencing and phenotypic drug susceptibility testing from over 40 countries for 13 anti-TB medicines.
Nov 15, 2023 · Of the more than 10 million people estimated to have fallen ill with tuberculosis (TB) in 2022, just over 400 000 people developed TB resistant to rifampicin (RIF), and 1.3 million people developed TB resistant isoniazid (INH). Drug resistance must be detected rapidly and accurately to initiate appropriate and effective treatment. Detection of RIF resistance has improved significantly with the introduction of rapid molecular diagnostic tools that require less complex infrastructure and are ...
Nov 7, 2023 · The WHO Global Tuberculosis Report 2023 provides 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 global TB commitments, strategies and targets. The 2023 edition of the report is based ...
May 20, 2024 · Multidrug-resistant TB (MDR-TB) is a form of TB disease caused by a strain of M. tuberculosis complex that is resistant to rifampicin and isoniazid. Globally, an estimated 410 000 people (95% UI: 370 000–450 000) developed multidrug- or rifampicin-resistant tuberculosis (MDR/RR-TB) in 2022. The treatment success rate for people diagnosed with ...
