How far each disease has come toward the 2030 goal. A live world heat-map of this progress is the next phase of the tracker.
Human cases fell from ~3.5M (1986) to just 10 in 2025 — on the verge of becoming the 2nd human disease ever eradicated.

Progress percentages are an illustrative rollup of WHO elimination metrics toward the 2030 roadmap; underlying case counts and validation counts are real and sourced above.
Data last updated October 2026. Refreshed from WHO Global Report on NTDs 2025, WHO NTD Day 2026 Brief, Mectizan 2025 Annual Highlights, and ITI Sept 2026 Report. These figures are refreshed automatically on the cadence at which the underlying sources publish (WHO releases its Global Report on NTDs and Global Health Observatory data annually; the Mectizan Donation Program and other company programs report annually, with quarterly updates). Sources include the World Health Organization (Global Report on Neglected Tropical Diseases & Global Health Observatory), the Mectizan Donation Program, the International Trachoma Initiative, The Carter Center, and the pharmaceutical donation programs cited above. Each figure carries its own source; where a value is a rollup or estimate it is labeled as such.
