Yes I believe they should be quarantined............in doing my paramedics degree in which I had to be tested for TB I found that people with full blown TB if left untreated kills half of the them. It is an easy disease to get if your around an infected person. According To the CDC (CDC Website)
TB is spread through the air from one person to another. The bacteria are put into the air when a person with active TB disease of the lungs or throat coughs or sneezes. People nearby may breathe in these bacteria and become infected.
When a person breathes in TB bacteria, the bacteria can settle in the lungs and begin to grow. From there, they can move through the blood to other parts of the body, such as the kidney, spine, and brain.
TB in the lungs or throat can be infectious. This means that the bacteria can be spread to other people. TB in other parts of the body, such as the kidney or spine, is usually not infectious.
People with active TB disease are most likely to spread it to people they spend time with every day. This includes family members, friends, and coworkers. So you take a chance anytime you are in public............hell unless your a hermit you take a chance every time someone comes into your home.........so yes I think they should be quarantined against spreading it to others.
