When Your Child Has Tuberculosis

If your child has been diagnosed with latent 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 latent TB is with a TB test.

• The infection can’t spread to others.

• They will need medicine to lower the chance of the infection becoming active at a later time.

If your child has been diagnosed with active TB, it means:

• Your child has active infection causing symptoms from TB, such as a cough, phlegm, tiredness (fatigue), fever, night sweats, or weight loss. Your child is likely to feel very sick.

• The infection can spread to others if the active TB involves the lung or throat.

• They must take medicine to help cure the disease.

TB bacteria are released into the air in tiny droplets when someone with active TB disease of the lungs or throat coughs, sneezes, or talks. The germs spread easily, especially in crowded spaces with poor airflow. Children who have close contact with someone with active TB and breathe in the germs for weeks or more 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 weak immune system or have HIV infection

In children, symptoms may include:

• Fever

• Fatigue or weakness

• Weight loss

• Night sweats

• Weakness

• Irritability

• Enlarged glands

Symptoms of TB infection in the lungs include:

• Shortness of breath

• Breathing fast

• Persistent cough

• Coughing up thick or bloody phlegm

There are two tests that can help detect latent 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 lab for testing. Your healthcare provider can tell you whether this test is right for your child.

For active TB disease, samples are taken from the involved area of the body (such as sputum, pus, or a biopsy) and testing is done on the samples to see if there is active TB infection.

• A negative skin or blood TB test usually means that your child’s body is free of TB bacteria.

• A positive result may mean that your child has been exposed to the germs that cause TB. The test may need to be repeated to confirm a positive PPD test. Your child will need other tests, such as a chest X-ray, to learn whether the infection is active. Your child’s healthcare provider may also take a sample of your child’s stomach secretions or mucus that comes up when your child coughs (sputum). These samples are sent to a lab and tested for TB bacteria. This helps the provider choose the best medicine for your child.

Both latent and active TB are treated with antibiotic medicines. Children with active TB take more antibiotics and for a longer time. Your child should begin feeling better shortly after starting treatment. But your child must continue to take all the medicine prescribed. This is the only way to cure the disease. Not taking all the medicine means your child won’t get well and can keep spreading the disease to others.

During treatment, your child may be offered or required to participate in a program called DOT (directly observed therapy). In this program, a nurse or healthcare worker gives the medicine to your child and watches them take it. DOT has been shown to result in better cure rates in people with active TB and is especially important with infectious forms of active TB such as when there is lung infection.

To help your child recover fully from active TB or to treat latent TB:

• Make sure your child takes all the medicine as directed, even when symptoms improve. Your child will take the medicine for 4 to 6 months or longer. Sticking to this schedule takes patience. But stopping medicine 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 child’s healthcare provider before using any prescription or over-the-counter medicines that haven’t been prescribed. Don’t 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 medicine is working, that side effects are being monitored and treated, and that your child's form of TB is getting better.

To help keep others safe when your child has active TB involving the lungs or throat:

• 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 healthcare provider right away if your child:

• Coughs more or coughs up blood

• Has chest pain

• Has trouble breathing

• Has night sweats that are not improving or that come back after being gone

• Has a fever (see Fever and children below)

Use a digital thermometer to check your child’s temperature. Don’t use a mercury thermometer. There are different kinds and uses of digital thermometers. They include:

• Rectal. For children younger than 3 years, a rectal temperature is the most accurate.
• Forehead (temporal). This works for children age 3 months and older. If a child under 3 months old has signs of illness, this can be used for a first pass. The provider may want to confirm with a rectal temperature.
• Ear (tympanic). Ear temperatures are accurate after 6 months of age, but not before.
• Armpit (axillary). This is the least reliable but may be used for a first pass to check a child of any age with signs of illness. The provider may want to confirm with a rectal temperature.
• Mouth (oral). Don’t use a thermometer in your child’s mouth until they are at least 4 years old.

Use a rectal thermometer with care. Follow the product maker’s directions for correct use. Insert it gently. Label it and make sure it’s not used in the mouth. It may pass on germs from the stool. If you don’t feel OK using a rectal thermometer, ask the healthcare provider what type to use instead. When you talk with any healthcare provider about your child’s fever, tell them which type you used.

Below is when to call the healthcare provider if your child has a fever. Your child’s healthcare provider may give you different numbers. Follow their instructions.

When to call a healthcare provider about your child’s fever

For a baby under 3 months old:

• First, ask your child’s healthcare provider how you should take the temperature.
• Rectal or forehead: 100.4°F (38°C) or higher
• Armpit: 99°F (37.2°C) or higher
• A fever of ___________as advised by the provider

For a child age 3 months to 36 months (3 years):
