What do we do
Consistent with World Health Assembly resolutions and in line with WHO’s roadmap for neglected tropical diseases, we support Member States to overcome the global impact of these diseases by accelerating access to prevention, diagnosis, treatment and care interventions for all those in need.
Neglected tropical diseases are a medically diverse group of infections caused by a variety of pathogens such as viruses, bacteria, protozoa and helminths. The 17 neglected tropical diseases prioritized by WHO affect more than 1 billion people worldwide and are endemic in 149 countries.
Why we work
Neglected tropical diseases cause immense human suffering and death. They pose a devastating obstacle to health, frustrate the achievement of the health-related United Nations Millennium Development Goals, and remain a serious impediment to poverty reduction and overall socioeconomic development.
How we improve access to health
Universal coverage for prevention and control interventions against neglected tropical diseases depends critically on the existence of stronger, more efficient health systems and access to free essential medicines of assured quality.
Through a well-trained and motivated work force at country level, we aim to prioritize the public health needs of poor and marginalized populations. We provide technical and strategic guidance in key areas, coordinate the distribution of donated medicines, promote WHO’s role in partnership involvement, strengthen capacity in countries endemic for these diseases, and leverage the contribution of stakeholders to the elimination and eradication of neglected tropical diseases. We deliver interventions through appropriate technology at sustainable cost and with the help of international partners we support Member States in the coordination and integration of national control programmes with the cooperation of sectors such as education, agriculture and veterinary public health.
Our approach to tackling neglected tropical diseases builds on five public-health strategies:
- preventive chemotherapy – the large-scale delivery of free and safe, single-dose, quality-assured medicines, either alone or in combination, at regular intervals to treat selected diseases;
- innovative and intensified disease management – the management of diseases that are difficult to diagnose and treat and which can, in most cases, trigger severe clinical manifestations and complications;
- vector control and pesticide management – the safe and judicious management of public-health pesticides to achieve vector control through integrated vector management;
- safe drinking-water, basic sanitation and hygiene services, and education – the prioritization of improved sanitation combined with delivering preventive chemotherapy and health education to sustain reductions in prevalence of many of these diseases;
- zoonotic disease management – the application of veterinary sciences and interventions to protect and improve human health (also referred to as veterinary public-health).
Although one approach may predominate for the control of a specific disease or group of diseases, effective control results when several approaches are combined and delivered locally.
Renewed momentum generated by unprecedented progress resulted in the World Health Assembly to adopt resolution WHA 66.12, in May 2013.
Of the 17 neglected tropical diseases, two are targeted for eradication – dracunculiasis (guinea-worm disease) by 2015 and yaws by 2020 and four for elimination (blinding trachoma, human African trypanosomiasis, leprosy and lymphatic filariasis) by 2020.
