TB is an airborne bacterial infection caused by Mycobacterium tuberculosis (M. tuberculosis) that usually affects the lungs (known as pulmonary TB). TB is a severe condition that can be fatal if not appropriately treated.
Everyone is susceptible to TB, and people with TB can be found in every country and from all age groups. The hope of having a world free of TB, leading to zero deaths, disease and suffering because of TB, is achievable. However, everyone will have a part to play in preventing the spread of TB worldwide.
