If TB bacteria gain entry to the blood stream from an area of damaged tissue, they can spread throughout the body and set up many foci of infection, all appearing as tiny, white tubercles in the tissues. [96] This severe form of TB disease, most common in young children and those with HIV, is called miliary tuberculosis. [97]
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
TB outbreaks have been reported in prisons and jails throughout the world, and is particularly concerning in the United States, [25] which incarcerates a larger proportion of its population than any other nation. The prevalence of TB in prisons is much higher than among the general population—in some countries as much as 40 times higher.

[1] [2] First discovered in 1882 by Robert Koch, M. tuberculosis has an unusual, waxy coating on its cell surface primarily due to the presence of mycolic acid.
[21] [22] According to the World Health Organization, approximately 10 million new TB infections occur every year, and 1.5 million people die from it each year – making it the world's top infectious killer (before COVID-19 pandemic). [21] However, there is a lack of sources which describe major TB epidemics with definite time spans and death ...
Even after completing the full course of medication, there is no guarantee that the tuberculosis bacteria have all been killed. [citation needed] "When a person develops active TB (disease), the symptoms (cough, fever, night sweats, weight loss etc.) may be mild for many months. This can lead to delays in seeking care, and results in ...
As of 2020, the world was not on track to meet those goals. [10] The WHO, as well as the Stop TB Partnership , are now aiming for the full elimination of TB by the year 2050, which will require a 1000-fold reduction in the incidence of the disease.
