Tuberculosis is a chronic bacterial disease, that is one of the most infectious and dangerous diseases that affect the lungs. They form nodules and "Tree and Bud" patterns in the lung, and if not treated and controlled it can cause symptoms such hemoptysis (coughing up blood). Additionally it only is infectiout when not under control.
Asthma and Allergies are legitimately the same thing, only asthma attacks or Bronchospasms cause swellings of the Bronchi.
