Tuberculosis (TB) is a disease caused by bacteria (germs) that can spread from person to person, carried through the air in tiny droplets. Most often, TB infects the lungs, but it also can harm other parts of the body. When not treated properly, TB can be fatal. There are two types of TB: inactive and active. Most children who have TB have the inactive form.
Inactive TB (TB Infection)
Active TB (TB Disease)
If your child has been diagnosed with inactive TB, it means your child:
Has live TB bacteria in the lungs, but the germs have been sealed off, much like a scab covers a wound. As a result, your child doesn’t have symptoms or feel sick. The only way to know your child has inactive TB is with a TB test.
Can’t spread the infection to others.
Will need medication to prevent the infection from spreading to others.
If your child has been diagnosed with active TB, it means your child:
Has symptoms of TB, such as a lasting cough, fatigue, fever, night sweats, and weight loss. Your child is likely to feel very sick.
Can spread the infection to others.
Must take medication to help cure the disease.
TB bacteria are released into the air in tiny droplets when someone with the disease coughs, sneezes, or talks. The germs spread easily, especially in crowded spaces with poor airflow. Children who breathe the germs for weeks or months are likely to become infected. Children are at special risk of TB if they:
Spend time every day with someone who has active TB.
Live in a crowded place, such as a shelter or group home, where germs spread easily.
Travel to or come from a country where TB is common.
Have a weakened immune system.
There are two tests that can help detect TB infection:
Skin test (PPD): A testing solution is placed just beneath the skin on your child’s arm to see if a reaction (such as a hard, red bump) occurs. Your child will need to return to the office in 2 or 3 days to have the arm checked. Be sure to keep the appointment. You will learn the test results during this visit.
Blood test: In this test, a small amount of blood is drawn and sent to a laboratory for testing. Your doctor can tell you whether this test is right for your child.
A negative result usually means that your child’s body is free of TB bacteria.
A positive result means your child has been exposed to the germs that cause TB. Other tests, such as a chest x-ray, are needed to learn whether the infection is active. Your child’s doctor may also take a sample of your child’s stomach secretions or sputum (mucus that comes up when your child coughs). These samples are sent to a laboratory and tested for TB bacteria. This helps the doctor choose the best medication for your child.
Both inactive and active TB are treated with medications. Children with active TB may take more medication for a longer time. Your child should begin feeling better shortly after starting treatment. But your child must continue to take all the medication prescribed. This is the only way to cure the disease. Not taking all the medication means your child won’t get well and can continue to spread the disease to others.
During treatment, your child may participate in a program called DOT (directly observed therapy). In this program, a nurse or healthcare worker gives the medication to your child. This makes it easier to finish treatment in the least amount of time.
To help your child recover fully from TB:
Make sure your child takes ALL the medication as directed, even when symptoms improve. Your child will take the medication for 6 months or longer. Sticking to this schedule takes patience. But stopping medication early or skipping doses means your child won’t get well. And it can create TB germs that are more deadly and harder to treat.
Arrange for your child to sleep in a room with good airflow.
Be sure your child gets plenty of rest and eats healthy meals. A nutritious diet full of fresh fruits and vegetables helps the body fight infection.
Check with your healthcare provider before using any prescription or over-the-counter medications that haven’t been prescribed. Do not give your child cough syrup. It won’t help and may be harmful.
Be sure your child goes to all follow-up exams. These help ensure that the medication is working and your child is getting better.
To help keep others safe:
Ask family, friends, and anyone else in close contact with your child to get tested. If your child has active TB, the TB germs can spread to other people.
Teach children to wash their hands often, particularly after coughing.
Make sure your child coughs into a tissue.
Use a plastic bag to throw away used tissues and other supplies.
Call the Doctor If Your Child:
Has a fever
In an infant under 3 months old, a rectal temperature of 100.4°F (38.0°C) or higher
In a child 3 to 36 months, a rectal temperature of 102°F (39.0°C) or higher
In a child of any age who has a temperature of 103°F (39.4°C)
A fever that lasts more than 24-hours in a child under 2 years old, or for 3 days in a child 2 years or older
Coughs more or coughs up blood.
Has night sweats.
Has chest pain.
Has trouble breathing.
