What is the policy of the USA if you have an infectious disease?

lol ok last question i think i got a good topic in my head now. If you do have an infectious disease what is the USA doing to keep it from spreading, let say you found out you had SARS and was still healthy enough to go on a dream trip to France, how do they keep you from going there, or keep them from coming here? If ordered to quarantined next week, and the person does not want to go, can the person still buy a plane ticket and fly? Im gonna try to make my topic the policies of the USA on controlling infectious disease.

The US isn't going to do much unless its a major public health concern (such as your example, SARS). ITs really not common as most people take the advice of health care providers who will tell you not to travel or go out in crowded places. So, its usually the person's choice to quarenteen him or herself. But, if said person proves to not take this advise, then law enforcement may intercede. This happened recently with a case of multi-drug resistant TB:

The quarantine order was the first since the government quarantined a patient with smallpox in 1963, according to the CDC.
