As many may be aware, tuberculosis is an infectious disease that primarily affects your lungs. The bacteria that cause tuberculosis are spread from person to person through tiny droplets released into the air via coughs and sneezes.
Tuberculosis, or TB, is a very common problem in African countries as well as in anyone with a severely compromised immune system. The spread of HIV/AIDS has contributed to the tangential health issues, among them, TB, which causes limited use of one's lungs and is often fatal.
Required TB testing is de rigeur in almost any employment situation. Almost all of us have undergone the ritual pricking of our forearms, knowing if we were free of TB yet again, that was most certainly a very good thing.
