First of all whether minimal or severe pulmonary tuberculosis is infectious. read on The typical symptoms of tuberculosis are a chronic cough with blood-tinged sputum, fever, night sweats and weight loss. Infection of other organs cause a wide range of symptoms. The diagnosis relies on radiology (commonly chest X-rays), a tuberculin skin test, blood tests, as well as microscopic examination and microbiological culture of bodily fluids. Tuberculosis treatment is difficult and requires long courses of multiple antibiotics. Contacts are also screened and treated if necessary. Antibiotic resistance is a growing problem in (extensively) multi-drug-resistant tuberculosis. Prevention relies on screening programs and vaccination, usually with Bacillus Calmette-Guérin (BCG vaccine). Tuberculosis is spread through the air, when people who have the disease cough, sneeze or spit. One third of the world's current population have been infected with M. tuberculosis, and new infections occur at a rate of one per second.[1] However, most of these cases will not develop the full-blown disease; asymptomatic, latent infection is most common. About one in ten of these latent infections will eventually progress to active disease, which, if left untreated, kills more than half of its victims. In 2004, mortality and morbidity statistics included 14.6 million chronic active cases, 8.9 million new cases, and 1.6 million deaths, mostly in developing countries.[1] In addition, a rising number of people in the developed world are contracting tuberculosis because their immune systems are compromised by immunosuppressive drugs, substance abuse, or AIDS. As these people spread into the West, Tuberculosis rates are increasing in these countries which had previously succeeded in virtually wiping it out.

If it is an active infection, yes. I'm not sure what you mean by minimal. It's like being pregnant, either you are or you aren't. If you know someone that has TB you don't want to be spending a lot of time with them until they have finished their antibiotic treatment. You need to be wearing a TB mask anytime you are near them.
