How the world is dismantling trachoma, humanity's oldest eye disease

January 30th, 2026: World NTD Day: Trachoma Featured as Success Story

Overview

For the first time since records began, fewer than 100 million people need treatment for trachoma—a bacterial eye disease that's been blinding humans since ancient Egyptian times. The number at risk has cratered 94% since 2002, from 1.5 billion to 97 million. Twenty-seven countries have eliminated it entirely, making trachoma one of the success stories celebrated at World NTD Day 2026 on January 30.

No vaccines. No breakthroughs. Just soap, antibiotics, and eyelid surgery delivered to the world's poorest villages.

The question now: Can the final 97 million be reached by 2030? Global development assistance for neglected tropical diseases fell 41% between 2018 and 2023. Funding gaps and conflict zones could turn this into another almost-won war.

  1. World NTD Day: Trachoma Featured as Success Story

    Latest Statement

    WHO and partners mark World Neglected Tropical Diseases Day with theme 'Unite. Act. Eliminate.' Trachoma highlighted as one of elimination successes, with 58 countries having eliminated at least one NTD toward 100-country target by 2030. WHO urges addressing stigma affecting people with NTDs.

  2. Global Trachoma Cases Fall Below 100 Million

    Milestone

    WHO announces 97.1 million people requiring interventions, first time below 100 million. Marks 94% reduction since 2002.

  3. Egypt Validated as Trachoma-Free

    Elimination

    Egypt becomes seventh Eastern Mediterranean country to eliminate trachoma, 27th globally.

  4. Fiji Becomes 26th Country

    Elimination

    Fiji validated for eliminating trachoma as public health problem.

  5. Senegal Validated

    Elimination

    Senegal joins growing list of countries eliminating trachoma.

  6. Burundi Eliminates Trachoma

    Elimination

    Burundi validated by WHO as having eliminated trachoma as public health problem.

  7. Papua New Guinea and Mauritania Validated

    Elimination

    WHO validates both countries for eliminating trachoma as public health problem.

  8. WHO Declares 'Golden Age of Elimination'

    Statement

    Dr. Tedros recognizes 11 countries for eliminating NTDs since January 2024 at World Health Assembly.

  9. One Billion Doses Delivered

    Milestone

    ITI and Pfizer announce one billionth Zithromax dose donated for trachoma treatment.

  10. Pfizer Extends Commitment

    Funding

    Pfizer commits to continue donating azithromycin through 2030, supporting final elimination push.

  11. Original Elimination Target Missed

    Assessment

    WHO extends global elimination deadline from 2020 to 2030 after falling short. Nine countries validated by then.

  12. 137 Million Still at Risk

    Data

    Number requiring interventions falls to 137 million, a 91% reduction from 2002 baseline.

  13. Mapping Project Completed

    Research

    GTMP finishes examining 2.6 million people, providing unprecedented data for targeting interventions.

  14. Global Trachoma Mapping Project Begins

    Research

    Largest infectious disease survey launches, using smartphones to map trachoma in 29 countries.

  15. First Eliminations Validated

    Milestone

    Oman becomes first country validated by WHO for eliminating trachoma as public health problem.

  16. Baseline Established

    Data

    WHO estimates 1.5 billion people at risk of trachoma, 7.6 million needing trichiasis surgery.

  17. Trachoma Elimination Campaign Launches

    Initiative

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

1967-1980

Smallpox Eradication (1967-1980)

WHO launched intensive global campaign using ring vaccination strategy, tracking every outbreak, and vaccinating contacts. Disease declared eradicated in 1980—the only human infectious disease ever completely eliminated. Last natural case occurred in Somalia in 1977.

Then

WHO declared world free of smallpox on May 8, 1980.

Now

Saves over $1 billion annually since 1980; proved disease eradication feasible with sustained commitment.

Why this matters now

Trachoma could become second disease eliminated globally as public health problem, but unlike smallpox requires behavior change (facial cleanliness, water access) not just medical intervention, making complete eradication more complex.

1986-present

Guinea Worm Eradication Campaign (1986-present)

Carter Center led campaign reduced Guinea worm cases from 3.5 million annually in 20 countries to fewer than 15 cases by 2021. Used community-based surveillance and behavior change—no vaccine or cure exists. Achieved 99.99% reduction through education and clean water access.

Then

Seventeen countries certified Guinea worm-free by 2022, including Ghana and DRC.

Now

Final eradication delayed repeatedly by conflict in South Sudan, Chad; demonstrates how political instability can stall final elimination stages.

Why this matters now

Shows behavior-change-based elimination can succeed but takes decades. Also warns that final mile—reaching last pockets in conflict zones—can drag on indefinitely despite 99%+ reduction.

1988-present

Polio Eradication Effort (1988-present)

Global campaign reduced wild polio by 99.9% from 350,000 annual cases in 125 countries to fewer than 50 cases in two endemic countries (Pakistan and Afghanistan) by 2020s. Uses mass vaccination campaigns, but faces vaccine hesitancy and access issues in conflict zones.

Then

Certified eradication in multiple regions; Africa declared wild polio-free in 2020.

Now

Final elimination repeatedly delayed; vaccine-derived polio emerged as new challenge requiring continued vigilance.

Why this matters now

Demonstrates that even with 99%+ reduction, final eradication can remain elusive for decades when disease persists in fragile states. Trachoma faces similar challenges in Ethiopia, Chad, South Sudan.
