Tuberculosis, commonly known just as TB, is an infectious bacterial disease that typically affects the lungs. The most common symptoms of tuberculosis include a persistent cough with bloody mucus, as well as fever, sweating, and weight loss. People can contract tuberculosis if they inhale droplets that are expelled with sneeze, cough, speaking or spitting by people infected by the disease. Tuberculosis, which has afflicted humans since ancient times, is now less common in developed countries, but the disease remains a health hazard in developing countries, where 95% of deaths currently occur. In 2018, 1.5 million people died from tuberculosis around the world.
