What Is Tuberculosis in Children?

Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis, a bacterium that primarily attacks the lungs but can affect other parts of the body, such as the brain, spine, or kidneys. In children, TB is particularly concerning because their developing immune systems are less equipped to fight the infection, leading to severe forms like miliary TB or TB meningitis. Unlike adults, children often contract TB from close contact with an infected person, such as a family member or caregiver, through airborne droplets from coughing, sneezing, or spitting. The disease can remain latent, showing no symptoms, or progress to active TB, which is contagious and life-threatening if untreated. According to the World Health Organization (WHO), 1.3 million children fell ill with TB globally in 2023, accounting for 12% of new cases, a stark reminder of its impact on younger populations.Bone Tuberculosis and Back TB (Pott’s Disease) – Healthhype

The resurgence of TB in children signals ongoing transmission in communities, as children typically contract the disease from adults. This makes childhood TB a barometer of broader public health challenges. Understanding the disease’s nature is the first step to addressing why cases are climbing and how to protect vulnerable kids.

Why Are TB Cases Rising?

The global rise in tuberculosis cases among children is a complex issue, driven by a mix of biological, social, and systemic factors. The WHO’s Global Tuberculosis Report 2024 noted 8.2 million new TB diagnoses in 2023, the highest since monitoring began in 1995, with children making up a significant portion. Several key drivers contribute to this surge, each amplifying the risk for kids.

Impact of COVID-19 Disruptions

The COVID-19 pandemic significantly disrupted TB control efforts worldwide. During 2020 and 2021, healthcare systems were overwhelmed, diverting resources and staff from TB programs to pandemic response. This led to delays in diagnosis and treatment, creating a backlog of undiagnosed cases. According to the WHO, the gap between estimated and notified TB cases narrowed to 2.7 million in 2023, but the earlier disruptions allowed TB to spread unchecked, particularly in households where children are exposed to infected adults. The pandemic also reduced access to routine screenings and preventive treatments, leaving many children vulnerable. For instance, TB preventive treatment (TPT) coverage dropped, increasing the risk of latent TB progressing to active disease in kids.

These disruptions highlight how global health crises can ripple into other areas, undermining decades of progress in TB control. Children, who rely on timely interventions, were hit hardest by these systemic failures.How to Treat a Child’s Fever at Home? – Healthhype

Socioeconomic and Environmental Factors

Poverty, overcrowding, and poor living conditions are major drivers of TB transmission. In low- and middle-income countries (LMICs), where 87% of global TB cases occur, families often live in cramped spaces with inadequate ventilation, facilitating the spread of airborne bacteria. The WHO identifies five key risk factors for TB: undernutrition, HIV infection, alcohol use disorders, smoking, and diabetes. For children, undernutrition is particularly critical, weakening their immune systems and making them more susceptible to TB infection. In 2023, 30 high-burden LMICs, including India, Indonesia, and the Philippines, accounted for 56% of global TB cases, with children in these regions facing heightened risks due to socioeconomic challenges.What Are the Signs of Anxiety in Children? – Healthhype

Urban slums, refugee camps, and areas with poor sanitation amplify TB transmission. Children in these settings are often exposed to infected adults in close-knit communities, increasing their risk of contracting the disease. Addressing these environmental factors is crucial to curbing the pediatric TB surge.Bone Tuberculosis and Back TB (Pott’s Disease) – Healthhype

Multidrug-Resistant TB Challenges

The rise of multidrug-resistant TB (MDR-TB) is a growing concern, particularly for children. MDR-TB, resistant to key drugs like isoniazid and rifampicin, is harder to treat and has a lower treatment success rate. In 2023, only 44% of the estimated 400,000 new MDR-TB cases globally received treatment, leaving many children untreated or undertreated. The Global Burden of Disease Study 2019 reported a 4.15% annual increase in MDR-TB incidence among children and adolescents from 1990 to 2019, with low-SDI regions bearing the brunt. Children with MDR-TB face prolonged treatment regimens, often lasting 9–18 months, which can be toxic and difficult to adhere to, especially in resource-poor settings.What Are the Signs of Anxiety in Children? – Healthhype

The spread of MDR-TB is linked to incomplete or improper treatment of regular TB, which allows resistant strains to develop. Children often contract MDR-TB from adults in their household, underscoring the need for robust contact tracing and early intervention.

Weakened Public Health Systems

Public health systems in many countries, particularly LMICs, struggle to keep pace with TB’s resurgence. Limited funding—only $1.1–1.2 billion annually for TB programs in LMICs compared to a needed $5 billion—hampers diagnostic and treatment efforts. The WHO notes that only one-fifth of the annual research funding target for TB is met, slowing the development of new diagnostics, drugs, and vaccines. In high-burden areas, shortages of trained healthcare workers and diagnostic tools like X-rays or molecular tests make it harder to identify TB in children, who often present with atypical symptoms.How Does Screen Time Affect Kids’ Sleep? – Healthhype

In Europe, the 2025 TB surveillance report from the European Centre for Disease Prevention and Control (ECDC) highlighted a 10% rise in pediatric TB cases, driven by ongoing transmission and delays in diagnosis. Weakened public health infrastructure, especially in non-EU countries, exacerbates the problem, allowing TB to spread unchecked in communities.Bone Tuberculosis and Back TB (Pott’s Disease) – Healthhype

Vulnerable Populations at Risk

Children are not a monolithic group; certain populations face higher risks of TB due to biological and social vulnerabilities. Understanding these groups helps tailor interventions to protect the most susceptible.

Young Children Under 5

Children under 5 are at the highest risk of severe TB due to their immature immune systems. The ECDC notes that over 2,400 cases in the WHO European Region in 2023 were in this age group, with higher risks of disseminated disease like TB meningitis. These young children often contract TB from household contacts, making early detection in adults critical to protecting them. The Bacille Calmette-Guérin (BCG) vaccine, given in some countries, reduces severe outcomes but does not fully prevent infection, leaving gaps in protection.

Children with HIV

HIV significantly increases TB risk, as it weakens the immune system, allowing latent TB to become active. In 2023, 161,000 TB-related deaths globally involved people with HIV, and children with HIV are particularly vulnerable. The WHO emphasizes that TB is the leading cause of death among HIV-positive individuals, highlighting the need for integrated TB-HIV care. Children with HIV often face delays in TB diagnosis due to overlapping symptoms, complicating treatment.

Children in High-Burden Areas

In regions like South Asia and sub-Saharan Africa, children face elevated TB risks due to high community transmission rates. Countries like India, China, and South Africa account for over 60% of global MDR-TB cases, with children often exposed in crowded households or schools. Poverty, malnutrition, and limited healthcare access exacerbate these risks, making prevention and early diagnosis critical.How to Treat a Child’s Fever at Home – Healthhype

Symptoms and Diagnosis Challenges

Diagnosing TB in children is notoriously difficult, contributing to the rise in cases. Unlike adults, children may not produce sputum, and their symptoms—such as persistent cough, fever, weight loss, or lethargy—are often mistaken for other illnesses like pneumonia. The WHO notes that diagnostic tools like the Mantoux skin test and interferon-gamma release assays have limitations, particularly in young children or those with compromised immune systems. Advanced molecular tests, like nucleic acid amplification, are more accurate but often unavailable in high-burden regions.

Missed or delayed diagnoses allow TB to progress, increasing transmission and severity. For example, autopsy studies in Zambia found active TB in 26% of HIV-negative children who died from pneumonia, suggesting underdiagnosis is a significant issue. Improved diagnostics, such as chest X-rays and standardized clinical guidelines, are essential to catching cases early.

Solutions to Curb Pediatric TB

Addressing the rise in childhood TB requires a multifaceted approach, combining medical, social, and policy interventions. Here are actionable solutions to protect children and reverse this troubling trend.Bone Tuberculosis and Back TB (Pott’s Disease) – Healthhype

Strengthening TB Diagnosis

Early and accurate diagnosis is the cornerstone of TB control. Expanding access to advanced diagnostics, like molecular tests and chest X-rays, in high-burden areas is critical. The WHO’s consolidated guidelines on TB diagnosis emphasize rapid testing to identify cases before they progress. Training healthcare workers to recognize atypical TB symptoms in children can reduce missed diagnoses. For instance, community-based screening programs targeting high-risk households can identify infected adults, preventing transmission to kids.

Enhancing Treatment Access

Effective treatment saves lives and stops transmission. For drug-susceptible TB, an 88% treatment success rate globally shows progress, but MDR-TB lags at 68%. Shorter, less toxic regimens for MDR-TB, as recommended by the WHO, are critical for children, who struggle with long treatment courses. Ensuring access to these regimens in LMICs, where most cases occur, requires increased funding and supply chain improvements. Completing treatment is vital to prevent resistance, so patient support programs, like counseling and nutritional aid, can improve adherence.

Preventive Measures for Kids

Preventive therapy, or TPT, can stop latent TB from becoming active, especially in high-risk children like those under 5 or with HIV. The WHO recommends TPT for household contacts of TB patients, yet coverage remains low. Expanding TPT access, alongside contact tracing, can protect vulnerable kids. The BCG vaccine, while not foolproof, reduces severe TB in children and should be prioritized in high-burden regions. Public health campaigns promoting hygiene practices, like covering coughs and proper sputum disposal, can also curb transmission.

Addressing Socioeconomic Drivers

Tackling poverty, malnutrition, and overcrowding is essential for long-term TB control. Programs providing nutritional support to children in LMICs can strengthen their immune systems, reducing TB risk. Improving housing conditions and ventilation in high-risk areas can limit airborne transmission. Multisectoral action, involving governments, NGOs, and communities, is needed to address these root causes. For example, studies show that rising GDP and education levels correlate with lower TB incidence, highlighting the role of socioeconomic development.

Boosting Research and Funding

The WHO’s Global Tuberculosis Report 2024 underscores the funding shortfall for TB research, with only 20% of the $5 billion target met in 2022. Investing in new vaccines, diagnostics, and drugs is critical. Fifteen TB vaccine candidates are in development, with six in phase 3 trials, offering hope for better prevention by 2028. Increased funding for TB programs, especially in LMICs, can ensure access to these innovations, protecting children from future outbreaks.

The Role of Global Collaboration

Ending the TB epidemic requires global cooperation. The United Nations’ 2023 High-Level Meeting on TB set ambitious targets, including a 90% reduction in TB incidence by 2035. Achieving this demands coordinated efforts from organizations like the WHO, the Global Fund, and national health ministries. The United States, as the largest bilateral TB donor, plays a pivotal role, but all countries must step up. Community engagement, especially in high-burden areas, can drive awareness and encourage early testing and treatment.
