Description of Tuberculosis
Today, tuberculosis (TB) tends to be concentrated among inner city dwellers, ethnic minorities and recent immigrants from areas of the world where the disease is still common. Alcoholics, who are often malnourished, are at high risk of developing the disease, as are people infected with HIV. It can occur anywhere, and no one is exempt from the threat of infection.

TB is caused by a germ that is transmitted from person to person by airborne droplets. Usually this infection is passed on as a result of very close contact, so family members of an infected person are endangered if the person continues to live in the same household and has not undergone proper treatment. (The family should take the precaution of seeing a doctor and getting a skin test.)

If an individual with active TB coughs or sneezes without covering the mouth and nose, droplets containing the tuberculosis germs are sprayed into the air and may be inhaled by anyone near the person. A tissue should always be used to cover the nose and mouth when coughing, sneezing or spitting, and hands should be washed promptly.

The vast majority of people who have TB germs in their bodies do not have an active case of the disease. Even if the disease is active, the disease is quite advanced. TB in children often occurs with childhood diseases. A simple skin test is available to detect individuals who have been or are infected with the TB germ. Those who have been infected will have a reaction where the skin becomes swollen. Once infected, most persons will generally test positive for the rest of their lives.

A positive reaction to the tuberculin test does not mean the person is ill or contagious to others. It means that the germs causing tuberculosis have been or are present in the body, and unless other symptoms are evident, the germs are probably not active. Their doctor may want to treat them to eliminate the germs so that a more serious case of active TB can be prevented.
