is a severe infection caused by bacteria called Mycobacterium tuberculosis. TB usually starts in the lungs. The bacteria are easily spread from one person to another through the air. They can live in your body a long time without making you sick. This is called latent TB. Latent means you do not have symptoms, but you may develop them later. Latent TB can develop into active TB if it is not treated.
Common signs and symptoms:
You can spread TB to others even if you do not yet have symptoms. TB mostly affects the lungs, but almost any part of the body can be infected. You may have any of the following:
- A fever or night sweats
- Weight loss without trying
- A cough for at least 3 weeks
- Blood in your sputum
- Chest or upper back pain, especially when you breathe
- Shortness of breath
Call 911 for any of the following:
- You have chest pain or cough up blood.
- You have trouble breathing.
Contact your healthcare provider if:
- You have a fever, headache, and a stiff neck.
- You have a rash or nausea, or you are vomiting.
- The whites of your eyes or your skin look yellow.
- Your urine looks like dark tea or coffee.
- Your symptoms do not go away, or they get worse, even after you take medicine.
- You have a cough that does not go away after 3 or 4 weeks.
- You have questions or concerns about your condition or care.
TB is treated with antibiotic medicine to fight the infection. You may need to take 3 to 4 types of antibiotics for up to 8 weeks. Then you may need to take at least 2 types of antibiotics for another 18 to 31 weeks.
Remember to take your medicines:
- Get involved in the Directly Observed Therapy (DOT) program. Healthcare providers help make sure you take your medicines correctly.
- Take your medicine at the same time every day. Each night, put out the pills for the next day. Mark a calendar each day you take your pills.
- Create reminders. Ask a family member or friend to remind you to take your pills.
- Keep medicines where you will see them. Keep the pills in a place where you cannot miss them, such as the bathroom or kitchen. Be sure they are out of the reach of children.
Prevent the spread of TB:
- Wash your hands often. Use soap and water. Wash your hands after you use the bathroom, change a child's diapers, or sneeze. Wash your hands before you prepare or eat food.
- Cover your mouth and nose. You may need to wear a mask. Use tissues when you cough or sneeze. Throw the used tissue away. If possible, flush used tissues down a toilet.
- Avoid close contact with others. Babies and elderly people are at increased risk for TB.
- Tell family, friends, and coworkers that you have TB. They may have latent TB and need to take medicine to prevent it from becoming active.
