About Tuberculosis


What is Tuberculosis?
Tuberculosis (TB) is one of the top 10 causes of death worldwide. TB is caused by bacteria (Mycobacterium tuberculosis) that most often infects the lungs.
Who is most at risk?
Tuberculosis mostly affects adults in their most productive years. However, all age groups are at risk. Over 95% of cases and deaths caused by TB are in developing countries. In 2016, 10.4 million people fell ill with TB, and 1.7 million died from the disease. TB is a leading cause of death for HIV-positive people: in 2016, 40% of HIV deaths were caused by TB.
Why is TB an urgent global health problem?
TB occurs in every part of the world. Multidrug-resistant tuberculosis (MDR-TB) is a form of TB caused by bacteria that do not respond to isoniazid and rifampicin, the two most powerful, first-line anti-TB drugs. Multidrug-resistant TB (MDR-TB) is on the rise and remains a public health crisis and a health security threat globally.
How can fast diagnostics help end TB?
One person infected with TB can typically infect 10-15 others and current TB testing methods require weeks to deliver a diagnosis. Slow diagnosis can lead to patients being placed in respiratory isolation unnecessarily or put on ineffective therapies. Fast and accurate diagnosis makes it possible to treat patients right away and can help put an end to the spread of TB.
