1 :
Tuberculosis or TB (short for tubercles bacillus) is a common and often deadly infectious disease caused by various strains of mycobacteria, usually Mycobacterium tuberculosis in humans.[1] Tuberculosis usually attacks the lungs but can also affect other parts of the body. It is spread through the air, when people who have the disease cough, sneeze, or spit.[2] Most infections in humans result in an asymptomatic, latent infection, and about one in ten latent infections eventually progresses to active disease, which, if left untreated, kills more than 50% of its victims.

"Is tuberculosis a communicable disease?" -- Very much so. Do you understand the word "communicable"?
3 :
Yes, but not everyone with tuberculosis is infectious to others. TB can be latent, meaning the person is infected and treatment is usually recommended, but the disease is not active and the person is not contagious. Active disease is usually in the lungs, and infection here or in the larynx is contagious to others
