Answer 3

Tuberculosis, commonly referred to as TB, is a bacterial infection that can spread through the lymph nodes and bloodstream to any organ in your body but is usually found in the lungs. Most people who are exposed to TB actually never develop symptoms. The bacteria can live in an inactive form in the body. Medication can be given to help get rid of the inactive bacteria. However, if the immune system weakens, such as in people with HIV or as we age, the bacteria can activate. In their active state, TB bacteria cause death of tissue in the infected organs, possibly resulting in death.
Because the bacteria that cause tuberculosis are transmitted through the air, the disease can be quite contagious. However, it is nearly impossible to catch TB simply by passing an infected person on the street. To be at risk, you must be exposed to the organisms constantly, by living or working in close quarters with someone who has the active disease. Even then, because the bacteria generally stay dormant after they invade the body; only 10% of people infected with TB will ever come down with the active disease. The remaining 90% will show no signs of infection, nor will they be able to spread the disease to others. Dormant infections can eventually become active, though, so even people without symptoms should receive medical treatment.
Once widespread, TB became relatively rare with the help of antibiotics developed in the 1950s. Today, however, a new and highly resistant form has emerged, creating a public-health hazard in many large cities worldwide. If you have TB -- in its active or dormant state -- you must seek medical treatment.

You will generally have no symptoms if you are infected with TB. In fact, you may not even be aware that you have the disease until it is revealed through a skin test, perhaps during a routine checkup. The Mantoux skin test -- performed in a doctor's office or health department -- is the most reliable detector of TB. A small amount of liquid material is injected just under the top layer of your skin on your arm. After two to three days, a doctor or nurse will read the test to see if it's positive -- a hard, red welt at the injection site of five to 15 millimeters, depending on your risk factors for developing active TB. A positive test means that you have been infected with TB at some point, though not necessarily in its active form. An X-ray of your lungs will help reveal if the disease is active.

If you are concerned that you have active TB, look for these symptoms:

Sensation of not feeling well
Cough, at first with yellow or green mucus and occasionally bloody later in the disease.
Fatigue
Shortness of breath
Weight loss
Slight fever, night sweats
Pain in the chest, back, or kidneys, and perhaps all three
