Tuberculosis, or TB, is an infectious bacterial disease caused by Mycobacterium tuberculosis, which most commonly affects the lungs. It is transmitted from person to person via droplets from the throat and lungs of people with the active respiratory disease.
But people infected with TB bacilli will not necessarily become sick with the disease. The immune system "walls off" the TB bacilli which, protected by a thick waxy coat, can lie dormant for years. When someone's immune system is weakened, the chances of becoming sick are greater.
If properly treated, tuberculosis caused by drug-susceptible strains is curable in virtually all cases. If untreated, more than half the cases may be fatal within five years.
The DHS collects data on women's and men's knowledge and attitudes concerning TB. Over 90 surveys have included TB questions.
The Service Provision Assessment (SPA) survey collects data on TB diagnostic services, TB treatment, and/or follow-up services and facilities following DOTS (Directly-observed Treatment, Short-course) strategy and any treatment other than DOTS strategy.
