Tuberculosis generally affects the lungs, but it can also affect other parts of the body. [1] Most infections show no symptoms, in which case it is known as latent tuberculosis. [1] Around 10% of latent infections progress to active disease that, if left untreated, kill about half of those affected. [1]
Tuberculosis (or TB) is an infectious disease, usually caused by Mycobacterium tuberculosis bacteria. [1] TB generally affects the lungs , but can also affect other parts of the body. [ 1 ]
Active tuberculosis can be contagious while latent tuberculosis is not, and it is therefore not possible to get TB from someone with latent tuberculosis. The main risk is that approximately 10% of these people (5% in the first two years after infection and 0.1% per year thereafter) will go on to develop active tuberculosis.

According to a 2013 review, tuberculosis elimination will require not just treating active tuberculosis but also latent cases, and eliminating tuberculosis by 2050 worldwide is not possible, although great reductions in infections and deaths are possible. [3] Addressing poverty is a further requirement for eliminating tuberculosis.
Tuberculous pericarditis is caused by infection with the bacterial species Mycobacterium tuberculosis. [1] Bacteria enter the body through inhalation and are ingested by white blood cells called macrophages. [1] Surviving bacteria multiply and can spread to other areas of the body.
There is a correlation between tuberculosis infections and cases of Pott's disease, as it's prevalent in areas where tuberculosis infections are common. Known risk factors like lower socioeconomic status, overcrowding, immunodeficiency, and interactions with people with tuberculosis can influence the rate of diagnosis.
