There are many lung diseases out in the world, but few are as deadly to the body as Pulmonary Tuberculosis. This disease on average kills 3 million people every year, and has infected almost a third of the human population. In 2010, it infected almost 9 million people, and was a factor to over 15 million deaths in the U.S alone. If caught soon enough, then the symptoms could be killed off with some medicines. If not, then you will have to take them for a longer period of time, around six months to be exact. The disease is easily preventable and treatment isn’t too rough on your body either.
