Can TB Be Cured?
Yes. Today, with modern medicine, in almost all instances, tuberculosis can be cured.
Most people who have TB will begin treatment by taking at least four different types of pills. After several months, your doctor may give you fewer types of medicines.
These drugs can cure TB if taken every day for at least 6 months. People with HIV infection have to take their medicines for longer periods of time.
Sometimes, TB germs are "resistant". This means that the TB medicines that are most often used do not kill the TB germs. When this happens, combinations of other medicines are given. Resistant TB is harder to cure, and it takes more time to control, but most people with resistant TB can be treated. Your doctor will make sure to have tests done at the laboratory to check for drug resistance.

Drug resistant TB can develop when a person with TB stops taking medicine too soon. A person with untreated drug resistant TB of the lungs or throat can transmit these drug resistant germs.
Taking your medicine regularly will cure you
. . . .
. . . ..
Always cover your mouth when you cough.
Tell all the people who you spend a lot of time with to get a Mantoux PPD skin test. This test is especially important for young children and for people who have HIV infection because they can become sick from TB in a short time.
Can I live as I always did?
During the first several weeks when you begin treatment for TB, your contacts and activities may be restricted until the doctor tells you that you are not contagious.
Most TB patients live at home and continue their normal activities (emphasis added) When you are no longer spreading TB germs, you can be near anyone, including children. You can continue your regular activities as long as you continue taking your medicine. You DON'T need a separate room or separate dishes.
TB used to scare people away, before we had modern medicine. Today, as long as you're taking your taking your medicine as directed, no one needs to be afraid to be near you.
Fresh air, rest and healthy foods can help you, but they cannot cure you. Only medicine can cure TB.
All TB tests, medicine and check-ups are available free of charge at the N.Y.C. Department of Health clinics.
