Roughly one-quarter of the world's population has been infected with M. tuberculosis, [6] with new infections occurring in about 1% of the population each year. [12] However, most infections with M. tuberculosis do not cause disease, [170] and 90–95% of infections remain asymptomatic. [88] In 2012, an estimated 8.6 million chronic cases were ...
Respiratory infections and tuberculosis: 6.85: 19.49%: Enteric infections ... With an average of 123.6 deaths per 100,000 from 2003 through 2010 the most dangerous ...
Scientific work investigating the evolutionary origins of the Mycobacterium tuberculosis complex has concluded that the most recent common ancestor of the complex was a human-specific pathogen, which underwent a population bottleneck.
The most common sites of extrapulmonary TB in those with HIV are the lymph nodes, liver, spleen, and central nervous system (TB meningitis). [2] TB meningitis in those with HIV has a mortality rate of 40%. [ 2 ]
If the most recent common ancestor of the M. tuberculosis complex were 40,000 to 70,000 years old, this would necessitate an evolutionary rate much lower than any estimates produced by genomic analyses of heterochronous samples, suggesting a far more recent common ancestor of the M. tuberculosis complex as little as 6000 years ago.

The most common symptoms of listeria infection include fever, fatigue and muscle aches, per the CDC. ... Tuberculosis Has Overtaken Covid As World's Deadliest Infectious Disease.
[19] [20] Globally, the severe malnutrition common in parts of the developing world causes a large increase in the risk of developing active tuberculosis, due to its damaging effects on the immune system. [21] [22] Along with overcrowding, poor nutrition may contribute to the strong link observed between tuberculosis and poverty. [23] [24]
Historically, tuberculosis was the most common cause of the lung cavity (and still is in areas where tuberculosis is endemic); [7] however, the cavity can also be caused by sarcoidosis, bullae, bronchiectasis, or cystic lung disease. [2] Chronic necrotizing aspergillosis and invasive aspergillosis are usually seen in immunocompromised people. [4]
