Transmission of the disease:

When people suffering from TB and coughs, sneeze, speak, or spit are infectious. These actions expel infectious droplets 0.5 to 5m in diameter. A sneeze can release up to 40,000 droplets! And any one of these droplets may transmit TB2

Signs and symptoms:

When the disease becomes active, 75% of the cases are pulmonary TB. Symptoms
include chest pain, coughing up blood, and a productive, prolonged cough for more than three weeks. Systemic symptoms include fever, chills, night sweats, appetite loss, weight loss, and becoming more fatigued quicker.
But in the other 25% of active cases, the infection moves from the lungs. This occurs more usually in immunosuppressed persons and young children.3

Prevention and/or treatment:

There are two common treatments for TB. The first, people with TB and their immediate circle of friends and associates are treated. The second treatment is the use of Vaccination in young children, but unfortunately to this date there is no available vaccine which is reliable for Adults.
