How can I keep from spreading TB?
The most important way to keep from spreading TB is to take all your medicine, exactly as directed by your doctor or nurse.
You also need to keep all of your clinic appointments! Your doctor or nurse needs to see how you are doing. You may need another chest x-ray or a test of the phlegm you may cough up. These tests will show whether the medicine is working. They will also show whether you can still give TB bacteria to others. Be sure to tell the doctor about anything you think is wrong.
If you are sick enough with active TB disease to go to a hospital, you may be put in a special room. These rooms use air vents that keep TB bacteria from spreading to other rooms. People who work in these special rooms must wear a special face mask to protect themselves from TB bacteria. You must stay in the room so that you will not spread TB bacteria to other people. Ask a nurse for anything you need that is not in your room.
If you are infectious while you are at home, there are certain things you can do to protect yourself and others near you. Your doctor may tell you to follow these guidelines to protect yourself and others:
Remember, TB is spread through the air. People cannot get infected with TB bacteria through handshakes, sitting on toilet seats, or sharing dishes and utensils with someone who has TB.
After you take medicine for about 2 or 3 weeks, you may no longer be able to spread TB bacteria to others. If your doctor or nurse agrees, you will be able to go back to your daily routine. Remember, you will get well only if you take your medicine exactly as your doctor or nurse tells you.
Think about people who may have spent time with you, such as family members, close friends, and coworkers. The local health department may need to test them for latent TB infection. TB is especially dangerous for children and people with HIV infection. If infected with TB bacteria, these people need medicine right away to keep from developing active TB disease.
What is multidrug-resistant TB (MDR TB)?
If you do not take your medicine as your doctor or nurse tells you, the TB bacteria may become resistant to a certain medicine. This means that the medicine can no longer kill the bacteria.
Drug resistance is more common in people who:
Sometimes the bacteria become resistant to two or more of the most important medicines: INH and RIF. This is called multidrug-resistant TB, or MDR TB. This is a very serious problem. People with MDR TB disease must be treated with special medicines. These medicines are not as good as the usual medicines for TB and they may cause more side effects. Also, most people with MDR TB disease must see a TB expert who can closely observe their treatment to make sure it is working.
People who have spent time with someone sick with MDR TB disease can become infected with these multidrug-resistant bacteria. If they have a positive skin test reaction, they may be given medicine to keep them from developing MDR TB disease. This is very important for people who are at high risk of developing MDR TB disease, such as children and HIV-infected people.
