You are correct, but such is the genre of these TV "medical" shows.

Tuberculosis is an airborne communicable disease that enters the body when one breathes in tiny "droplet nuclei" released from an infected person. These respiratory secretions are released when a person with active infectious TB coughs, sneezes, laughs, sings, or talks with projection without proper covering of the mouth and nose. These tiny droplet nuclei can remain suspended in the air for hours.
In a hospital setting, if a patient is suspected to have TB, he/ she should be put on airborne precautions and immediately isolated in a private room with negative air pressure and outside exhaust. There is a special anteroom in which visitors must first enter. All doors and windows must be kept closed. Special NIOSH-approved filter respirator masks must be worn by all health care workers or visitors entering the room. If the patient is to go for tests or procedures outside of his/ her room, the patient must wear a mask.
