Tuberculosis (TB) is a communicable disease* that is a major cause of ill health, one of the top 10 causes of death worldwide and the leading cause of death from a single infectious agent (ranking above HIV/ AIDS).

TB is caused by the bacillus Mycobacterium tuberculosis, which is spread when people who are sick with TB expel bacteria into the air; for example, by coughing.

TB is a disease of poverty. Economic distress, vulnerability, marginalization, stigma and discrimination are often faced by people affected by TB.

TB is curable and preventable. About 85% of people who develop TB disease can be successfully treated with a 6-month drug regimen.

*Communicable diseases are diseases that can be spread from one person to another and cause a large number of people to get sick
