Neglected tropical diseases(NTDs) are a diverse group of communicable diseases that prevail in tropical and subtropical conditions in 149 countries.
NTDs are a diverse set of bacterial, viral, and parasitic pathogens that collectively cause significant illness and debilitation, primarily in impoverished communities of low and middle-income countries.
Neglected tropical diseases (NTDs) are called "neglected," because they generally afflict the world's poor and historically have not received as much attention as other diseases.
These diseases affect more than one billion people and cost developing economies billions of dollars every year.
Populations living in poverty, without adequate sanitation and in close contact with infectious vectors and domestic animals and livestock are those worst affected.
Effective control can be achieved when selected public health approachesare combined and delivered locally.
Interventions are guided by the local epidemiology and the availability of appropriate measures to detect, prevent and control diseases.
Implementation of appropriate measures with high coverage will contribute to achieving the targets of the World Health Organization (WHO) NTD Roadmapon neglected tropical diseases, resulting in the elimination of many and the eradication of at least two by 2020.
In May 2013, the 66th World Health Assembly resolved to intensify and integrate measures against neglected tropical diseases and to plan investments to improve the health and social well-being of affected populations.
WHO is working with the Member States to ensure the implementation of resolution 12.
In 2016, the 69th Assembly adopted resolution 21 on addressing the burden of mycetoma and requested WHO, through the Strategic and Technical Advisory for Neglected Tropical Diseases, “to define a systematic, technically-driven process for evaluation and potential inclusion of additional diseases among the ‘neglected tropical diseases’”.
Accordingly, in 2017 the 10th meeting of the Strategic and Technical Advisory Group for Neglected Tropical Diseases received proposals for the addition of diseases and, pursuant to the required procedures, chromoblastomycosis and other deep mycoses, scabies and other ectoparasites and snakebite envenoming have been added to the NTD portfolio.
