It has a transmitting character through contagion. Today TB is curable and deaths mostly due to sheer negligence and ignorance. In the rural areas acute poverty is the principal reason.
Tuberculosis is a contagious disease especially if the patient has open cavity . It means the bacterias are more active especially in Lung TB. If the patient has TB of some other part like bone TB or intestine TB then it is not contagious as bacteria will be present inside the body. But in Lung TB bacterias spread while coughing or sneezing and hence it is contagious.
