World Neglected Tropical Diseases Day - January 30, WHO observance launched in 2020

World Neglected Tropical Diseases Day is a WHO observance held every January 30. Formally designated by the World Health Assembly in 2020, it mobilises action against a group of 20 diseases that affect more than one billion people, mostly in the world’s poorest communities. The day is advocacy- and reporting-focused, not a public holiday.

The one-line summary

WHO observance on January 30. Established 2020. Targets 20 diseases affecting 1+ billion people in 149 countries. Focuses on mass drug administration, surveillance, and drug donation commitments. Not a public holiday.

Origin and history

The World Health Organization formally designated World Neglected Tropical Diseases Day at the 73rd World Health Assembly in May 2020. The chosen day - January 30 - was the eighth anniversary of the 2012 London Declaration on NTDs, a public-private partnership commitment signed by 13 pharmaceutical companies, the Bill & Melinda Gates Foundation, the World Bank, donor governments, and endemic-country health ministries.

The London Declaration set out to control or eliminate ten NTDs by 2020 by combining drug donations, mass drug administration (MDA) campaigns, water-sanitation infrastructure, and vector control. By 2020, the WHO reported that 600 million people no longer required MDA for at least one NTD - a milestone the formal day was designed to publicise. The WHO NTD Roadmap 2021-2030 extended the targets.

The WHO NTD list (2024)

The current list of 20 NTDs is grouped into disease categories that reflect transmission route, pathogen type, and available intervention. The diseases include Buruli ulcer, Chagas disease, dengue and chikungunya, dracunculiasis (guinea-worm disease), echinococcosis, foodborne trematodiases, human African trypanosomiasis, leishmaniasis, leprosy, lymphatic filariasis, mycetoma, onchocerciasis (river blindness), rabies, schistosomiasis, soil-transmitted helminthiases, snakebite envenoming, taeniasis/cysticercosis, trachoma, and yaws.

The 2019 expansion of the list from 17 to 20 diseases added snakebite envenoming, scabies, and other ectoparasites - a recognition that burden had been previously underestimated. Snakebite in particular was elevated after the WHO published a strategy in 2019 calling it “the world’s highest-mortality neglected disease.” The list is reviewed every five years.

London Declaration and drug donations

The 2012 London Declaration committed pharmaceutical companies to donate the drugs needed for mass drug administration indefinitely. The largest commitments came from GSK (albendazole for soil-transmitted helminths and lymphatic filariasis, 2 billion tablets cumulatively), Merck & Co. (ivermectin for onchocerciasis and lymphatic filariasis, “as much as needed for as long as needed”), Pfizer (azithromycin for trachoma), Novartis (multidrug therapy for leprosy), and Eisai (DEC for lymphatic filariasis).

These donations enabled the WHO’s preventive chemotherapy strategy, in which entire at-risk populations receive annual or biannual drug doses regardless of infection status. By 2023, the WHO reported more than 1.7 billion NTD treatments delivered in a single year. The model has been described as the largest public-health drug-provision programme in history.

NTD Roadmap 2021-2030

The current strategic framework is the WHO NTD Roadmap 2021-2030, launched in November 2020 alongside the formal designation of World NTD Day. The roadmap sets three overarching targets: reduce the number of people requiring NTD interventions by 90%, eliminate at least one NTD in 100 countries, and eradicate guinea-worm disease and yaws.

The roadmap is structured around three pillars - accelerate programmatic action (more MDA, more integration, more surveillance), intensify cross-cutting approaches (water-sanitation-hygiene, vector management, One Health), and change operating models and culture to embed NTD work in national health systems. By 2024, the WHO reported 50 countries having eliminated at least one NTD.

Progress and challenges

Major NTD progress since the London Declaration includes: lymphatic filariasis eliminated as a public-health problem in 17 countries; trachoma eliminated in 18 countries; onchocerciasis eliminated in four countries in the Americas plus Niger; dracunculiasis (guinea worm) reduced from an estimated 3.5 million cases in 1986 to under 15 annual cases in 2023.

Persistent challenges include: drug-resistance risk in mass-treatment programmes; supply-chain fragility for donated drugs; funding gaps for the water-sanitation infrastructure that sustains long-term gains; surveillance in conflict-affected endemic zones; and integration of NTD programmes into universal-health-coverage platforms so they survive donor transitions.

Annual themes

The WHO publishes a theme each year. Recent themes include “Unite. Act. Eliminate.” (2024), “Following the NTD Road Map 2021-2030” (2023), “Achieving health equity to end the neglect of NTDs” (2022), and “End the neglect. End the inequalities. End the NTDs.” (2021). Themes emphasise the equity framing of NTD work.

Observation and debate

World NTD Day is one of several WHO disease-specific observance days - others include World Malaria Day (April 25), World Tuberculosis Day (March 24), World AIDS Day (December 1), and World Hepatitis Day (July 28). Critics note the proliferation of such days risks “observance fatigue” among donor governments and the public; defenders argue that disease-specific days provide essential accountability moments for each programme’s funding and policy commitments.

How to verify and primary sources

The authoritative source for World Neglected Tropical Diseases Day is the WHO NTD Department. The WHO publishes a Road Map 2021-2030 PDF, an annual progress report, and a dedicated web portal at who.int/teams/control-of-neglected-tropical-diseases. Endemic-country data are aggregated by the Global Health Observatory. Drug donation figures come from the annual reporting of each pharmaceutical partner and the WHO LF and onchocerciasis elimination programmes.
