We identified this PDF through public web research and acquired the frozen research copy only from the publisher's official URL. It was not supplied by a customer, user, or partner and was not uploaded through DocAccessible. This page is the reviewed HTML conversion of the official CDC publication, produced for the PDF-to-HTML benchmark corpus. Automated diagnostics and the completed project-owner review record are published below. This is not an independent audit, certification, or conformance claim. The publisher's PDF linked above remains the document of record.

Conversion method and notes

Method: text extraction with manual semantic markup.

  • Source is a two-page infographic-style fact sheet; the opening statistics and the burden statistics were rendered as unordered lists.
  • The printed asterisk (*) and double-asterisk (**) source markers were kept as printed; both source citations are listed once beneath the burden statistics.
  • Challenge topics and CDC role areas (Diagnose, Treat, Prevent, Sustain) were rendered as headed subsections; the two closing 'progress' and 'more work' sequences were rendered as ordered lists matching the source numbering.
  • Decorative artifacts (the March 2025 footer date) were dropped; the printed cdc.gov/globalhivtb address is kept as a working link.

Automated attention

  • Visual representation: Figures or images are planned, but no IMG or FIGURE element is present. Text alternatives may exist elsewhere and require manual source comparison.

Visual-coverage attention

  • Fewer than 70% of sampled source-page text sequences aligned to the HTML render.
  • At least one sampled PDF page with image objects has no aligned HTML visual element.
  • Planned visual representations are absent: figures or images.

The source score measures normalized text retention and local order. Visual coverage compares aligned rendered regions and object representation. Neither automated result independently establishes visual equivalence, semantic correctness, or accessibility conformance. Human review is a separate, exact-revision project-owner record.

Document content

  • In 2023, globally an estimated 1.25 million children aged 0-14 years old fell ill with TB around the world.
  • 52% of children under 5 with TB go undiagnosed, untreated or unreported.

The Burden of Child and Adolescent TB

In 2023:

  • 191K* children died from TB.
  • 73%** died before the age of five.
  • 96%** of the children who died from TB did not receive TB treatment.
  • * World Health Organization Global TB Report 2024
  • ** 2023 WHO Roadmap towards ending TB in children and adolescents

Challenges in Addressing Child and Adolescent TB

Difficulties in Diagnosis

TB in children is difficult to diagnose with traditional diagnostic tools, but consistent use of child-friendly specimens and increasing access to chest x-rays can improve case-finding among children.

TB Preventive Treatment Remains Low

Provision of TB preventative treatment (TPT) to children in contact with someone with TB remains low, with only 42% of those eligible receiving TPT every year.

HIV-associated TB

An estimated 33% of deaths among children living with HIV are due to TB.

CDC’s Role in the Fight Against Child and Adolescent TB

Diagnose

Working with ministries of health (MOH) to promote use of child friendly approaches and diagnostics to diagnose TB in children. In Eswatini, Lesotho, Malawi, Tanzania, and Uganda, CDC is working with MOH and Baylor College of Medicine to evaluate the latest screening and diagnostic methods to determine the most effective and efficient ways to diagnose TB among children.

Treat

Linking every child screened for TB through PEPFAR platforms to diagnostic evaluation and treatment for TB. In 2024, 95% of all children and adolescents with TB at CDC-supported facilities had a known HIV status*.

Prevent

Scaling-up TB preventive treatment to all eligible children, including household contacts of people with TB and children living with HIV. Since 2017, CDC accounts for over 60% of PEPFAR TPT initiations for children living with HIV*.

Sustain

Providing leadership and technical assistance to identify and address gaps that hinder childhood TB elimination. CDC and the International Union Against TB and Lung Disease have established a Centre of Excellence, providing a global, virtual platform with twelve ministries of health to provide a community of learning and practice for child and adolescent TB in countries hardest hit by the epidemic.

Significant progress has been made in response to child and adolescent TB, but there is still much left to do.

Recent Progress: Responding to Child and Adolescent TB

  1. Less invasive diagnostic methods discovered, simplifying the diagnosis of TB in children.
  2. Shorter treatment regimens for drug-susceptible TB among children are obtainable, reducing burden on children and their families/and can improve treatment outcomes for children.
  3. Nearly all TPT and TB treatment regimens are now available in dispersible, pediatric formulations.
  4. A comprehensive Roadmap for ending TB in children and adolescents—supported by CDC and updated in 2023—identifies key actions to close remaining gaps.

There Is More Work to Be Done to End Childhood TB

  1. Slow adoption and uptake of child-friendly diagnostic tools hinders diagnosis of TB in children.
  2. Shorter treatment regimens for children require capacity to differentiate severe TB disease from uncomplicated, non-severe disease, slowing uptake of/access to this preferred treatment.
  3. Expanding access to TPT for all children living with HIV and household contacts of people with TB is critical to close the prevention gap.
