I remember when I used to work for the CDC in a Tuberculosis clinic. That was, like, two years ago.
TB is usually controllable. This guy has a nasty flavor. He's also uncooperative, duplicitous and probably was assisted in some way by the father-in-law who worked also for CDC. He may also be the victim of his own ignorance, arrogance, bad advice, vague medical directions, etc.
Most TB in the world starts off very treatable and manageable - through not taking your meds and not following up with testing and treatment, it can become very bad.
When I worked in Chicago there was this one patient who started off with garden-variety TB. Over the course of over 10 years of avoiding public health officials and doing partial treatments, he become untreatable. When he was finally 'caught' for the last time, he was committed to a public hospital and basically had to have a lung removed coercively. It's next to impossible to get legal coercion and court orders on people with communicable disease. You'd be amazed at the infrequency that it is even attempted, and the even smaller amount of success.
Andrew Card is the worst kind of public health offender to me because he has a sense of entitlement and an attitude of superiority - his life is too important to be interrupted by public servants, even when they are trying to protect the public. Luckily it's actually really hard to transmit TB on a plane - very rare and usually only to those very close to you, and only if the flight is really long. A few people may be at risk but I bet no one gets TB disease as a result of this guy.
