What are Neglected Tropical Diseases (NTD)?

  • Neglected tropical diseases (NTDs)– a diverse group of communicable diseases that prevail in tropical and subtropical conditions in 149 countries – 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.
  • Seven of the most common NTDs can be found in a number of countries—primarily in low- and middle-income countries of Africa, Asia, and Latin America.
  • Controlling the vectors (e.g., mosquitoes, black flies) that transmit these diseases and improving basic water, sanitation, and hygiene are highly effective strategies against these NTDs.
The NTD Crisis
  • NTDs such as dengue, lymphatic filariasis and visceral leishmaniasis (Kala-Azar) afflict 1 billion people worldwide, and yet, are not prioritised in the public health narrative in many parts of the world.
  • India bears the largest burden of NTDs in the world, accounting for 40 per cent of the global lymphatic filariasis disease burden and almost a quarter of the world’s visceral leishmaniasis cases.

Government’s efforts regarding NTD

  • In recent years, the government has made concerted efforts to address the nation’s NTD burden, especially visceral leishmaniasis and lymphatic filariasis which were slated to be eliminated by 2020 and 2021 respectively.
  • India has already eliminated several other NTDs, including guinea worm, trachoma, and yaws.
  • Measures taken include Mass Drug Administration (MDA) for lymphatic filariasis prevention in endemic districts and Indoor Residual Spraying (IRS) to control the breeding of sandflies that transmit visceral leishmaniasis.
  • The Accelerated Plan for Elimination of Lymphatic Filariasis (APELF) was launched in 2018, as part of intensifying efforts towards the elimination of NTDs.
  • A WHO-supported regional alliance established by the governments of India, Bangladesh, and Nepal in 2005 to expedite early diagnosis and treatment of the most vulnerable populations and improve disease surveillance and control of sandfly populations (Kala-azar).

About the World Neglected Tropical Diseases Day declaration

  • London Declaration on NTDs on 30th January, 2012 recognised the global burden of NTDs.
  • Officials from the World Health Organization (WHO), the World Bank, the Bill and Melinda Gates Foundation, representatives from leading global pharmaceutical companies as well as representatives of several national governments met at London’s Royal College of physicians to pledge to end the diseases.
  • The ongoing 74th World Health Assembly declared 30th January as ‘World Neglected Tropical Diseases (NTD) Day. The first World NTD Day was celebrated informally in 2020.
