Prevention is the best method to avoid TB. The only available and widely tested vaccine is the bacillus Calmette–Guérin (BCG) but there are some doubts in its ability to protect people from infection in modern environments. New vaccines are currently under development.

Antibiotics are commonly prescribed but resistance is a growing problem.

Active TB is usually treated with a combination of several antibiotics while the latent type requires just one.

If not treated properly, TB can be deadly.
