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. [11] However, most infections with M. tuberculosis do not cause disease, [169] and 90–95% of infections remain asymptomatic. [87] In 2012, an estimated 8.6 million chronic cases were ...
Aspergilloma in an old tuberculosis cavity; healed, calcified tuberculous lesions are also present towards the right of the image Healed tuberculous cavity, where the entire left lung is destroyed. Post-tuberculosis lung disease (PTLD) is ongoing lung disease that is caused by tuberculosis (TB) but persists after the infection is cured. [1]
Management of tuberculosis refers to techniques and procedures utilized for treating tuberculosis (TB), or simply a treatment plan for TB.. The medical standard for active TB is a short course treatment involving a combination of isoniazid, rifampicin (also known as Rifampin), pyrazinamide, and ethambutol for the first two months.
Humans are the only known reservoirs of M. tuberculosis. A misconception is that M. tuberculosis can be spread by shaking hands, making contact with toilet seats, sharing food or drink, or sharing toothbrushes. However, major spread is through air droplets originating from a person who has the disease either coughing, sneezing, speaking, or ...
Because MDR tuberculosis is an airborne pathogen, persons with active, pulmonary tuberculosis caused by a multidrug-resistant strain can transmit the disease if they are alive and coughing. [41] TB strains are often less fit and less transmissible, and outbreaks occur more readily in people with weakened immune systems (e.g., patients with HIV ).
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.
In fact, death from tuberculosis was greater in diabetic patients. [9] Persons with HIV and latent tuberculosis have a 10% chance of developing active tuberculosis every year. "HIV infection is the greatest known risk factor for the progression of latent M. tuberculosis infection to active TB. In many African countries, 30–60% of all new TB ...
In tuberculosis-endemic regions, tuberculous pericarditis accounts for 50-90% of cases of effusive pericarditis, depending on HIV status. [6] In developed countries, it only accounts for about 4% of cases. [6] Tuberculous pericarditis is a deadly disease with a mortality rate of up to 40% in the first 6 months after diagnosis. [6]
