This disease is till date one of the leading cause of death worldwide. In fact, 2015 witnessed 1.8 million deaths due to Tuberculosis (TB) with India leading the count, followed by Indonesia, China, Nigeria, Pakistan and South Africa.

Tuberculosis (TB) is an infection caused by bacteria called Mycobacterium tuberculosis which essentially affects the pulmonary area (lungs). It is an airborne disease which means – the bacteria spreads through the air from person to person. It is important for people to treat Tuberculosis (TB) properly and immediately otherwise it can become fatal. It may be fatal but Tuberculosis falls under the list of preventable and curable diseases. 

About Tuberculosis:

Despite being a prevalent bacterial disease which affects the lungs there are many facts about TB that remain unknown.  There are two types of TB – latent TB Disease and TB Disease. People with latent TB don’t feel sick, they don’t spread the bacteria nor do they portray symptoms of any kind. With latent TB is essentially when the person has the potential of contracting TB disease. When the bacteria within the body start becoming active and multiply that’s when the person will go from having latent TB infection to TB Disease.
