If you have active TB of the lungs or throat, you should:
Ask family, friends, and the people you work with to get tested. Active TB can spread to other people.
Don’t have close contact with people until your healthcare provider says it’s OK.
Wash your hands often, especially after coughing. Use soap and clear, running water and scrub your hands for at least 20 seconds.
Use a tissue to cover your mouth when you cough. If you don’t have a tissue, cough into your elbow, not your hand. Wash your hands after you cough or sneeze.
Wear a mask, if you’ve been told to do so, when you go out in public or visit your healthcare provider.
Use a plastic bag to throw away old tissues and other supplies.
Make sure you are in a well-ventilated room.
