Tuberculosis Control

Tuberculosis is most often a disease of the lungs. It spreads from person to person when someone with TB disease coughs, sneezes or speaks, expelling bacteria into the air that others breathe. Untreated tuberculosis disease is a serious and urgent public health threat.

Yes, Tuberculosis Still Happens

Just fifty years ago, active TB disease was widespread in Mississippi, constituting a major health crisis.

Today, extensive efforts have brought tuberculosis under control. However, infections continue to be detected. MSDH maintains a very active TB surveillance program to identify cases and treat them before they can spread.

Testing is the best defense. You can be tested for TB at any county health department. If you think you may have been exposed to TB, or that you have symptoms, schedule a testing appointment by calling 855-767-0170.

What is TB?

Tuberculosis is a bacterial infection which most often in the lungs, but it can appear in or spread to other parts of the body. Untreated, TB can destroy lung tissue and make breathing difficult or impossible. TB is a particular public health concern because it can spread easily through the air when a person with TB disease speaks, coughs or sneezes.

The Mississippi State Department of Health acts quickly to treat cases of TB disease to limit its spread, and to treat TB infection before it progresses to TB disease.

Treatment is prevention: It is important to treat TB infection to reduce the chance that it will progress to TB disease and become contagious. Since a person with TB infection has no signs or symptoms and does not feel sick, the only way to know whether you are infected is to have a TB test.

TB Exposure

For a person to become infected a fairly long or repeated exposure is often required. The people most likely to become infected are contacts to (people who share air with) a person who has TB disease and persons living in or traveling to countries where TB is prevalent.

An estimated 10-15 million U. S. residents and one-third of the world’s population are currently infected with TB. A blood test called an Interferon Gamma Release Assay (IGRA) is the preferred test to identify TB infection.

Is TB infection dangerous?

The danger of TB infection is not knowing that you have it. If left untreated, TB infection can progress to TB disease, which can be fatal. TB infection does not cause sickness and has no symptoms. Persons with TB infection cannot spread the disease to others. A skin test or blood test can detect the presence of TB infection.

• You have spent time with a person who has active TB.
• You have the symptoms of TB: coughing for more than two weeks, pain in the chest, coughing up blood, loss of appetite, weight loss and fatigue.
• You have a chronic disease such as diabetes, or another condition that weakens the immune system.
• You have lived in or visited a foreign country where TB is common.
• You have lived or worked in a place where TB is common: migrant farm camps, prisons, homeless shelters or other crowded places where disease can spread.
• You use drugs injected with needles that may not be sterile.
