wat is tuber culosis(TB)?

Answer 1

Tuberculosis (TB) is a disease caused by bacteria called Mycobacterium tuberculosis. The bacteria usually attack the lungs. But, TB bacteria can attack any part of the body such as the kidney, spine, and brain. If not treated properly, TB disease can be fatal. TB disease was once the leading cause of death in the United States.

TB is spread through the air from one person to another. The bacteria are put into the air when a person with active TB disease of the lungs or throat coughs or sneezes. People nearby may breathe in these bacteria and become infected.

However, not everyone infected with TB bacteria becomes sick. People who are not sick have what is called latent TB infection. People who have latent TB infection do not feel sick, do not have any symptoms, and cannot spread TB to others. But, some people with latent TB infection go on to get TB disease.

People with active TB disease can be treated and cured if they seek medical help. Even better, people with latent TB infection can take medicine so that they will not develop active TB disease.

Answer 2

Tuberculosis is a contagious infection caused by an airborne bacterium, Mycobacterium tuberculosis.

Tuberculosis usually affects the lungs, although it can attack almost any organ in the body. Other mycobacteria (such as Mycobacterium bovis or Mycobacterium africanum) occasionally can cause a similar disease.

Tuberculosis has been a serious public health problem for a long time. In the 1800s, the disease was responsible for more than 30% of all deaths in Europe. With the advent of antituberculosis antibiotics in the 1940s, the battle against tuberculosis seemed to be won. Unfortunately—because of factors such as inadequate public health resources, reduced immune response due to AIDS, the development of drug resistance, and extreme poverty in many parts of the world—tuberculosis continues to be a deadly disease. Worldwide, there are 8 million new cases of symptomatic tuberculosis and 3 million deaths from the disease every year. It is believed that one third of all the people in the world have a dormant (latent) tuberculosis infection, although only about 5 to 10% progress to active tuberculosis disease.

In the United States and other developed countries, tuberculosis has been more common among older people, whereas it is a disease of young adults in poorer countries. Of the cases reported in the United States in 2000, 22% involved people older than age 65. There were more cases among older people because they were more likely to have acquired the infection in an era when tuberculosis was more common. As the body's immune system weakens with age, dormant bacteria become reactivated. Fortunately, the incidence of tuberculosis among older people is declining because each generation entering old age has a lower rate of latent infection.

Because tuberculosis has existed in Europe longer than anywhere else, people of European descent are somewhat more resistant to the disease than people whose ancestors lived in parts of the world where tuberculosis was introduced more recently. Thus, in the United States, tuberculosis is more common among blacks, Native Americans, certain other minorities, and immigrants from non-European countries. Additionally, people in these groups tend to be poorer, live in crowded conditions, and have less access to medical care—all conditions that are conducive to the spread of tuberculosis.

Answer 4

TB is a bacterial disease that is difficult to treat. It can affect any part of the body, but the lungs are the most affected. If you have a bad cough that doesn't go away, then you should get it looked at right away.
The antibiotics given for TB are usually given for 6 months or more.
