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.
You should get tested for TB if you have any of the following risk factors:
If you have a positive reaction to the TB test, the Health District will schedule a chest x-ray. A test of the phlegm you cough up may be required after your X-rays are reviewed.
The TB skin test is used to find out if you have TB infection. A small amount of testing fluid is injected just under the skin on the underside of the forearm. After two or three days, you must return to have your skin test read by a health care worker to determine if it is positive or negative. A positive result usually means that you have been infected by someone with active TB disease. If you miss the skin reading, the entire test will have to be given again.
Symptoms depend on where in the body the TB bacteria are growing. TB bacteria usually grow in the lungs. TB in the lungs may cause symptoms such as:
