TB is an infectious disease caused by a bacteria affecting the lungs, but it can occur anywhere in the body. In the year of 2015 alone, believe it or not but 1.8 million of people worldwide have died from the disease. As per the World Health Organization, it is estimated that each year roughly 9.1 million of people will get infected with TB. There are two types of TB: Latent and Active. In Latent TB, the bacteria remains in your body, however, it is inactive and therefore does not produce symptoms and the person is not considered to be contagious unless the disease becomes active. On the other hand, in Active TB – the person is contagious as the person has symptoms which can be transmitted to others.
