- TB of the central nervous system.
- TB of other places.
How common is extrapulmonary TB?
It is estimated that extrapulmonary tuberculosis (EPTB) accounts for 15–25% of all cases of TB. HIV patients, especially with low CD4 counts, have higher rates of EPTB. Children are more likely to have skeletal TB than adults.
What is extrapulmonary tuberculosis?
Extrapulmonary tuberculosis (EPTB) is an infectious disease caused by Mycobacterium tuberculosis that occurs in organ systems other than the lungs. Epidemiologic risk factors include birth in high TB-prevalent countries, exposure at place of residence/work in an institutional setting, and homelessness.
Which TB is more common?
The most common form of active TB is lung disease, but it may invade other organs, so-called “extrapulmonary TB.”
What does extrapulmonary mean?

Why is tuberculosis becoming more common?
But repeated exposure to large concentrations of infected people – such as happens in prisons, overcrowded houses and hospitals – can increase a person’s chance of infection. An immune system weakened by disease or even certain types of medication can also increase a person’s risk of developing full-blown TB.
How is extrapulmonary TB transmitted?
How is it transmitted? Mainly transmitted from person to person through the air. When someone with active pulmonary TB coughs, sneezes, spits or speaks, infected droplets can be projected into the air. Inhaled bacteria can then lodge in the lungs and cause TB.
Is extrapulmonary tuberculosis curable?
In contrast with PTB treatment, cure for EPTB is difficult to define. Moreover, there are no established criteria for the end of treatment. In case of studies on TB lymphadenitis, residual lymph nodes at the end of treatment have usually been used for assessing treatment outcomes.
What is the difference between pulmonary TB and extrapulmonary TB?
Tuberculosis (TB) is an infectious disease that typically affects the lungs, though it can also involve other body parts. When it affects the lungs, it’s called pulmonary TB. TB outside of the lung is called extrapulmonary TB.
