Parent education only.
Most children do well when problems are recognised early and care is sought at the right time. This guide explains what parents can observe safely at home and when to seek medical help.
What is tuberculosis?
Tuberculosis (TB) is an infection caused by Mycobacterium tuberculosis. In children, TB may affect the lungs, lymph nodes, brain, bones or other organs. Diagnosis can be difficult and should be supervised by clinicians using history, examination, tests and contact screening.
Common symptoms and signs
- Cough lasting more than two weeks, especially with household TB contact.
- Poor weight gain, weight loss, persistent fever or night sweats.
- Swollen neck glands or persistent tiredness.
- Symptoms may be subtle in young children.
How it spreads or happens
- Usually spread through air from an infectious adult or adolescent with lung TB.
- Risk is higher in young children, malnutrition, immunosuppression and close household exposure.
- TB is treatable, but treatment must be completed exactly as prescribed.
Home care while arranging appropriate review
Focus on observation, fluids, comfort and timely review.
Avoid self-starting antibiotics, leftover medicines, or unverified treatment plans.
- Seek evaluation if there is household TB contact or persistent symptoms.
- Bring previous X-rays, test reports and vaccination or treatment records.
- Support nutrition, rest and adherence once treatment is prescribed.
- Do not hide TB exposure history; it helps protect the child and family.
Red flags / when to seek urgent medical care
Seek urgent medical assessment if your child has any of the following:
- Severe headache, vomiting, drowsiness, seizure or neck stiffness.
- Breathlessness, chest pain, coughing blood or severe weakness.
- Poor feeding, weight loss, persistent fever or swollen glands in a young child with TB contact.
- Any child on TB medicines with jaundice, severe vomiting, rash or unusual illness needs urgent review.
Important facts for parents
- A normal-looking child can still need TB contact screening.
- BCG helps protect against severe childhood TB forms but does not prevent all TB.
- Stopping TB medicines early can cause relapse and drug resistance.
