Tuberculosis (TB), also known as the "white death", or historically as consumption, is an infectious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. Tuberculosis generally affects the lungs, but it can also affect other parts of the body. Most infections show no symptoms, in which case it is known as latent tuberculosis. Around 10% of latent infections progress to active disease which, if left untreated, kill about half of those affected. Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. Infection of other organs can cause a wide range of symptoms.
Sir Peter Karel, Baron Piot, is a Belgian-British microbiologist known for his research into Ebola and AIDS.
Tuberculosis is diagnosed by finding Mycobacterium tuberculosis bacteria in a clinical specimen taken from the patient. While other investigations may strongly suggest tuberculosis as the diagnosis, they cannot confirm it.
Extensively drug-resistant tuberculosis (XDR-TB) is a form of tuberculosis caused by bacteria that are resistant to some of the most effective anti-TB drugs. XDR-TB strains have arisen after the mismanagement of individuals with multidrug-resistant TB (MDR-TB).
Loop-mediated isothermal amplification (LAMP) is a single-tube technique for the amplification of DNA and a low-cost alternative to detect certain diseases that was invented in 2000 at the University of Tokyo. Reverse transcription loop-mediated isothermal amplification (RT-LAMP) combines LAMP with a reverse transcription step to allow the detection of RNA.

FIND functions as a product development partnership, engaging in active collaboration with over 150 partners to facilitate the development, evaluation, and implementation of diagnostic tests for poverty-related diseases. The organisation's Geneva headquarters are in Campus Biotech. Country offices are located in New Delhi, India; Cape Town, South Africa; and Hanoi, Viet Nam.
The Xpert MTB/RIF is a cartridge-based nucleic acid amplification test (NAAT) for simultaneous rapid tuberculosis diagnosis and rapid antibiotic sensitivity test. It is an automated diagnostic test that can identify Mycobacterium tuberculosis (MTB) DNA and resistance to rifampicin (RIF). It was co-developed by the laboratory of Professor David Alland at the University of Medicine and Dentistry of New Jersey (UMDNJ), Cepheid Inc. and Foundation for Innovative New Diagnostics, with additional financial support from the US National Institutes of Health (NIH).
Sir Alimuddin Zumla,, FRCP, FRCPath, FRSB is a British-Zambian professor of infectious diseases and international health at University College London Medical School. He specialises in infectious and tropical diseases, clinical immunology, and internal medicine, with a special interest in HIV/AIDS, respiratory infections, and diseases of poverty. He is known for his leadership of infectious/tropical diseases research and capacity development activities. He was awarded a Knighthood in the 2017 Queens Birthday Honours list for services to public health and protection from infectious disease. In 2012, he was awarded Zambia's highest civilian honour, the Order of the Grand Commander of Distinguished services - First Division. In 2022, for the fifth consecutive year, Zumla was recognised by Clarivate Analytics, Web of Science as one of the world's top 1% most cited researchers. In 2021 Sir Zumla was elected as Fellow of The World Academy of Sciences.
Soumya Swaminathan is an Indian paediatrician and clinical scientist known for her research on tuberculosis and HIV. From 2019 to 2022, she served as the chief scientist at the World Health Organization under the leadership of Director General Tedros Adhanom Ghebreyesus. Previously, from October 2017 to March 2019, she was the Deputy Director General of Programmes (DDP) at the World Health Organization.
Extrapulmonary tuberculosis is tuberculosis (TB) within a location in the body other than the lungs. It accounts for an increasing fraction of active cases, from 20 to 40% according to published reports, and causes other kinds of TB. These are collectively denoted as "extrapulmonary tuberculosis". Extrapulmonary TB occurs more commonly in immunosuppressed persons and young children. In those with HIV, this occurs in more than 50% of cases. Notable extrapulmonary infection sites include the pleura, the central nervous system, the lymphatic system, the genitourinary system, and the bones and joints, among others.
Oriol Mitjà i Villar is a Catalan-born Spanish researcher and consultant physician in internal medicine and infectious diseases with expertise in poverty-related tropical diseases. He has conducted research at the Lihir Medical Centre in Papua New Guinea since 2010 on new diagnostic and therapeutic tools to eradicate yaws. He was awarded the Princess of Girona Award in the scientific research category. Currently at the Germans Trias i Pujol Research Institute, Mitjà is conducting research on SARS-CoV-2 coronavirus disease (COVID-19) and strategies to control the infection at a community level.
The Vaccine Confidence Project (VCP) founded in 2010 by Heidi Larson, was developed in response to hesitancy and misinformation on vaccination programmes such as those that caused a boycott of polio eradication efforts in Northern Nigeria in 2003–04. It is an early warning system to identify and evaluate public confidence in vaccines, with the purpose of tackling the problem early, when it is likely to be manageable.
Truenat is a chip-based, point-of-care, rapid molecular test for diagnosis of infectious diseases. The technology is based on the Taqman RTPCR chemistry which can be performed on the portable, battery operated Truelab Real Time micro PCR platform. Truenat is developed and manufactured by Goa-based Molbio Diagnostics Private Limited.
The WHO model list of essential in vitro diagnostics, or WHO list of essential diagnostic tests (EDL) is a World Health Organization (WHO) priority list of medical tests that provides guidance for individual countries on which tests to use and which not to. It was first published in 2018, then revised in 2019, and a third edition was published in 2020.
Tuberculosis elimination is the effort to reduce the number of tuberculosis (TB) cases to less than one per 1 million population, contrasted with the effort to completely eradicate infection in humans worldwide. The goal of tuberculosis elimination is hampered by the lack of rapid testing, short and effective treatment courses, and completely effective vaccine. The WHO as well as the Stop TB Partnership aim for the full elimination of TB by 2050—requiring a 1000-fold reduction in tuberculosis incidence. As of 2017, tuberculosis has not been eliminated from any country.

Pai is the Canada Research Chair of Epidemiology and Global Health at McGill University.
Rachel Kiddell-Monroe LL.M is a Montreal-based academic, activist, and lawyer. She is the General Director of See Change Initiative and faculty at McGill University where she teaches about humanitarian aid.
From 1929 to 1933, 251 infants in Lübeck, northern Germany, were given three doses of the oral BCG vaccine against tuberculosis, which was accidentally contaminated with the bacteria responsible for the disease. 173 later developed signs of the illness and 72 died.
Novel Njweipi Chegou is a Cameroonian molecular biologist who is a professor at the Stellenbosch University Immunology Research Group.
