What is Tuberculosis? The Atlanta man was believed to be infected with the form of the tuberculosis bacteria known as “extensively drug-resistant” TB, abbreviated XDR TB. What is Tuberculosis? Tuberculosis is a bacterial infection that primarily affects the lungs, and the infection is spread via air droplets released during coughing, spitting, sneezing, or talking. In the other 25% of active cases, the infection moves from the lungs, causing other kinds of TB, collectively denoted extrapulmonary tuberculosis. Not all infections with M. tuberculosis cause TB disease and many infections are asymptomatic.

What is Tuberculosis
TB patients with drug sensitive disease may develop drug resistant tuberculosis if they fail to take antituberculosis medications as prescribed, as well as TB patients who have been prescribed an ineffective treatment plan. XDR TB is a rare form of the disease that is resistant to the drugs routinely used to treat tuberculosis infections and is extremely difficult to treat. This severe form of TB disease is most common in infants and the elderly and is called miliary tuberculosis. What is Tuberculosis? Although it was established that the pulmonary form was associated with “tubercles” by Dr Richard Morton in 1689, due to the variety of its symptoms, TB was not identified as a single disease until the 1820s and was not named “tuberculosis” until 1839 by J. L. Schönlein.

Each one of these droplets may transmit the disease, since the infectious dose of tuberculosis is very low and inhaling fewer than ten bacteria may cause an infection. What is Tuberculosis? Miliary tuberculosis –now commonly known as disseminated TB–occurs when the infection invades the circulatory system, resulting in millet-like seeding of TB bacilli in the lungs as seen on an X-ray. The rise in HIV infections and the neglect of TB control programs have enabled a resurgence of tuberculosis. What is Tuberculosis? Drug-resistant tuberculosis is transmitted in the same way as regular TB. Primary resistance occurs in persons infected with a resistant strain of TB. A person with fully susceptible TB develops secondary resistance (acquired resistance) during TB therapy because of inadequate treatment, not taking the prescribed regimen appropriately, or using low-quality medication. What is Tuberculosis? In latent TB, the person has a significant reaction to the Mantoux skin test with no symptoms of tuberculosis, and no TB organisms found in the sputum.
What is Tuberculosis? TB is a highly contagious air-born bacteria, therefore contracting tuberculosis depends on whether the person comes into contact with the bacteria or not. Tuberculosis is spread through the air when a person with untreated pulmonary TB coughs or sneezes. What is Tuberculosis? The most important way to stop the spread of tuberculosis is for TB patients to cover the mouth and nose when coughing, and to take all the TB medicine exactly as prescribed by the physician.
