This information describes tuberculosis (TB), how it is spread, and what precautions are taken when someone has it or is being ruled out for it in the hospital.
What is tuberculosis (TB)?
TB is an infection that usually affects the lungs. Other parts of the body, including the brain, lymph nodes, kidneys, and bones, can also be infected with TB. Anyone can be infected with TB, no matter what age. People with weakened immune systems are at an increased risk for TB.
All cases of TB are reported to the local or state health department so that health authorities can keep track of TB infections.Back to top
How is TB spread?
TB is spread through the air when a person coughs or sneezes. The germs can stay in the air for several hours. People who breathe in the air containing these germs can become infected. TB is not spread by germs on dishes, drinking glasses, or linens.
People with TB are most likely to spread the germs to people they spend a lot of time with. Family members or coworkers have the highest risk of being infected. Usually, you must spend a long time with someone before you can become infected.Back to top
