Insights
Global pediatric tuberculosis (TB) control has stalled, with rising incidence in some regions and insufficient progress toward World Health Organization (WHO) End TB targets. Enhanced child-focused prevention and surveillance are crucial for renewed momentum.
Area of Science:
- Global Health
- Epidemiology
- Pediatric Infectious Diseases
Background:
- Pediatric tuberculosis (TB) control lags behind adult populations, with unclear impacts from recent epidemiological shifts like the COVID-19 pandemic on World Health Organization (WHO) End TB milestones.
- Understanding trends in pediatric TB is vital for global health strategies.
Purpose of the Study:
- To examine global, regional, and national trends in pediatric TB incidence from 2013 to 2023.
- To assess progress toward the 2025 End TB milestone, considering changes since 2019.
- To summarize treatment outcomes and TB preventive treatment (TPT) coverage for child contacts in high-burden countries (HBCs).
Main Methods:
- Utilized age-specific WHO data for 209 countries and territories (2013-2023).
- Analyzed global, regional, and national pediatric TB incidence trends.
- Evaluated progress towards the 2025 End TB milestone and TPT coverage for child contacts.
Main Results:
- Pediatric TB incidence increased by 14% since 2015, reaching 62.74 per 100,000 in 2023.
- Significant regional disparities observed: rising incidence in South-East Asia versus a decline in Africa.
- Over half of HBCs are further from the 2025 milestone; TPT coverage for young children remains critically low.
Conclusions:
- Global progress in pediatric TB control has plateaued, indicating a need for urgent intervention.
- Strengthened child-focused prevention strategies and improved surveillance are essential to achieve End TB targets.
Objective:
Pediatric tuberculosis (TB) remains an important part of the global TB burden; however progress in this population has been slower and less consistent than that in adults. The influence of recent epidemiological shifts, including those following the COVID-19 pandemic, on progress toward the World Health Organization (WHO) End TB milestones remains unclear.
Methods:
Using age-specific WHO data for 209 countries and territories from 2013 to 2023, we examined global, regional, and national trends in pediatric TB incidence. We assessed progress toward the 2025 End TB milestone, evaluated changes relative to 2019, and summarized treatment outcomes and TB preventive treatment (TPT) coverage for child household contacts in high-burden countries (HBCs).
Results:
In 2023, the pediatric TB incidence reached 62.74 per 100,000, representing a 14% increase since 2015. Regional patterns differed markedly; the incidence rose steadily in South-East Asia and accounted for >50% estimated cases among the 30 highest-burden countries, while Africa showed a sustained decline. Over half of the HBCs moved further from the 2025 milestone, and TPT coverage for children under five < 5 years remained well below target levels.
Conclusions:
Global progress in pediatric TB control has plateaued. Stronger child-focused prevention and surveillance are essential to regain momentum toward End TB targets.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
