Answers:
Tuberculosis is a common and often deadly infectious disease cause by mycobacteria, mainly Mycobacterium tuberculosis. Tuberculosis usually attacks the lungs (as pulmonary TB) but can also affect the central nervous system, the lymphatic system, the circulatory system, the genitourinary system, the gastrointestinal system, bones, joint, and even the skin. Other mycobacteria such as Mycobacterium bovis, Mycobacterium africanum, Mycobacterium canetti, and Mycobacterium microti also cause tuberculosis, but these species are less common.
The classic symptoms of tuberculosis are a chronic cough next to blood-tinged sputum, fever, night sweats, and weight loss. Infection of other organs cause a wide range of symptoms. The diagnosis relies on radiology (commonly chest X-rays), a tuberculin skin test, blood test, as well as microscopic examination and microbiological culture of bodily fluids. Tuberculosis treatment is difficult and requires long courses of multiple antibiotics. Contacts are also screened and treated if vital. Antibiotic resistance is a growing problem in (extensively) multi-drug-resistant tuberculosis. Prevention relies on screening programs and vaccination, usually with Bacillus Calmette-Guérin (BCG vaccine).
Tuberculosis is spread through the heavens, when people who have the disease cough, sneeze, or spit. One third of the world's current population has be infected with M. tuberculosis, and new infections occur at a rate of one per second. However, most of these cases will not develop the full-blown disease; asymptomatic, quiescent infection is most common. About one in ten of these latent infections will eventually progress to stirring disease, which, if left untreated, kills more than half of its victims. In 2004, mortality and morbidity statistics included 14.6 million chronic live cases, 8.9 million new cases, and 1.6 million deaths, mostly in developing countries.[2] In accumulation, a rising number of people in the developed world are contracting tuberculosis because their immune systems are compromised by immunosuppressive drugs, substance abuse, or AIDS. The distribution of tuberculosis is not uniform across the planet with about 80% of the population in several Asian and African countries testing positive in tuberculin tests, while one and only 5-10% of the US population test positive. It is estimated that the US has 25,000 new cases of tuberculosis respectively year, 40% of which occur in immigrants from countries where on earth tuberculosis is endemic.
Tuberculosis (TB) is a potentially serious infectious disease that primarily affects your lungs. Tuberculosis is spread from person to person through tiny droplets released into the air. Most culture who become infected with the bacteria that cause tuberculosis don't develop symptoms of the disease. Source(s): http://www.mayoclinic.com/health/tubercu…
