Tuberculosis in children can present in multiple forms with diverse clinical manifestations and may lead to serious long-term complications if not diagnosed and treated promptly.
Childhood tuberculosis is generally classified into four major forms that require medical treatment:
Primary tuberculosis (primary TB), also known as initial infection
Acute tuberculosis, including tuberculous meningitis and miliary tuberculosis
Post-primary respiratory tuberculosis, which includes pulmonary tuberculosis and tuberculous pleuritis
Extrapulmonary tuberculosis, encompassing several forms such as tuberculous lymphadenitis, osteoarticular tuberculosis, spinal tuberculosis (Pott’s disease), peritoneal tuberculosis, tuberculous pericarditis, genitourinary tuberculosis, and intestinal tuberculosis.
Children with primary tuberculosis infection often present with fatigue, loss of appetite, weight loss, and low-grade fever in the afternoon, occasionally accompanied by episodes of high fever.
In addition, affected children may experience dry cough, sputum production, chest pain, and shortness of breath. Depending on the specific type of tuberculosis involved, the clinical presentation may include other characteristic symptoms associated with the affected organ system.
Tuberculosis in children requires timely diagnosis and prompt treatment.
Types of tuberculosis in children
Primary tuberculosis (Primary infection)
Primary tuberculosis is the most common form of tuberculosis in children. It may occur in children under 14 years of age, but it is most frequently seen in children younger than five years, particularly those who have not received the BCG vaccination.
Children with primary tuberculosis are often asymptomatic, or they may present with mild, transient symptoms resembling influenza, such as low-grade fever, fatigue, or malaise. In some cases, the disease may follow a mild clinical course and resolve spontaneously, particularly in children with a strong immune response.
Acute tuberculosis
Tuberculous meningitis and acute miliary tuberculosis are considered early and severe complications of primary tuberculosis. These conditions carry a high risk of mortality if not recognized promptly and may lead to serious long-term sequelae when diagnosis and treatment are delayed.
They can occur at any age, but are most commonly seen in children younger than two years, especially those without BCG immunization.
Tuberculous meningitis
Tuberculous meningitis typically develops two to twelve months after primary tuberculosis infection. Early manifestations may include low-grade fever and behavioral changes.
Within about one week, symptoms may progress to fever around 38°C, severe headache, and vomiting. Clinical examination may reveal neck stiffness, along with neurological manifestations such as seizures, coma, strabismus, epilepsy, or ptosis.
Delayed diagnosis can result in severe neurological sequelae, including intellectual disability, behavioral disorders, epilepsy, hemiparesis, limb contractures, blindness, or deafness.
Miliary tuberculosis
Military tuberculosis is a disseminated and severe form of pulmonary tuberculosis that often occurs within the first weeks following primary infection.
Typical symptoms include high fever, tachycardia, vomiting, abdominal pain, and diarrhea. Unlike typhoid fever, patients usually do not present with rose spots on the abdomen. Respiratory manifestations are prominent, including dyspnea and cyanosis.
Children with military tuberculosis are at high risk of developing tuberculous meningitis.
Respiratory tuberculosis
Pulmonary tuberculosis and tuberculous pleuritis are more commonly observed in older children and adolescents approaching puberty rather than in younger children.
Clinical manifestations often include persistent cough, low-grade fever, weight loss, and poor appetite.
Extrapulmonary tuberculosis
Extrapulmonary tuberculosis usually occurs as a late complication following primary infection and may affect multiple organ systems.
Common forms include:
Spinal tuberculosis (Pott’s disease): Early symptoms include back pain, which may gradually progress to spinal deformity or kyphosis.
Osteoarticular tuberculosis: Characterized by joint swelling, pain, and possible sinus tract formation with purulent discharge from the affected bones or joints.
Genitourinary tuberculosis: May present with hematuria, and in boys may be accompanied by testicular swelling.
Tuberculous lymphadenitis: Typically presents as clusters of enlarged lymph nodes, which may become matted and eventually form draining sinuses if untreated, leading to permanent scarring.
Intestinal tuberculosis: Symptoms may include chronic diarrhea or stools mixed with mucus and blood.
Diagnosis and treatment of tuberculosis in children
Diagnosing tuberculosis in children is often more challenging than in adults. Even in cases of pediatric pulmonary tuberculosis, identifying Mycobacterium tuberculosis can be difficult because young children are often unable to produce sputum for laboratory examination. In addition, primary tuberculosis in children frequently presents with symptoms similar to common respiratory infections, which further complicates early diagnosis.
Regarding treatment, tuberculosis in children is managed with therapeutic regimens similar to those used in adults. However, it is essential that parents strictly adhere to the physician’s instructions, ensuring that children complete the full course of treatment, typically lasting 6-9 months, with the appropriate drug dosage and standardized treatment regimen. Proper adherence to therapy is critical to achieving disease control and preventing relapse or drug resistance.
Persistent cough in older adults may be a warning sign of pulmonary tuberculosis.
Advice for parents
Parents should ensure that their children receive the BCG vaccination according to the National Expanded Immunization Program to help prevent tuberculosis in children.
Early detection and treatment of family members with tuberculosis are essential to prevent children from being exposed to the source of infection.
Maintain children’s overall health and nutritional status by providing a balanced and adequate diet, helping to prevent malnutrition and strengthen immunity.
Ensure a healthy living environment, with well-ventilated, clean, and hygienic housing conditions.
If a family member is diagnosed with tuberculosis, children should be kept at a safe distance from the infected individual, and close contact such as kissing or prolonged exposure should be avoided to reduce the risk of transmission.
When children present with symptoms suggestive of tuberculosis such as persistent cough and fever, weight loss or failure to gain weight, and night sweats they should be promptly taken to a specialized healthcare facility for evaluation and treatment.
Treatment should follow the standardized regimen of the National Tuberculosis Control Program, ensuring strict adherence to the DOTS strategy (Directly Observed Treatment, Short-course) to achieve optimal therapeutic outcomes and prevent disease progression or drug resistance.
