Current Global Progress

  • As of May 2025, 56 countries have eliminated at least one NTD, aligned with WHO’s 2030 target (100 countries).
  • Between Jan 2023 – May 2025, 17 countries were officially acknowledged by WHO for NTD elimination.
  • World NTD Day: Observed annually on 30th January.

What Are NTDs?

  • NTDs are a group of infectious diseases affecting over 1 billion people, mainly in tropical and poor regions.
  • Caused by parasites, bacteria, viruses, fungi, or toxins.
  • Common NTDs include:
    • Lymphatic Filariasis (Elephantiasis)
    • Onchocerciasis (River Blindness)
    • Schistosomiasis
    • Soil-transmitted helminths
    • Trachoma, Dengue, Kala-azar (Visceral Leishmaniasis)

Impact of Official Development Assistance (ODA) Cuts  

  • Major donors like the US and UK have withdrawn NTD funding:
    • USAID previously provided US$ 1.4 billion, supporting 3.3 billion treatments across 26 countries, helping 14 of them eliminate at least one NTD.
    • UK ended its ‘Ascend’ NTD programme in 2021.

WHO Warning:

  • On 10 April 2025, WHO cautioned that over 70% of country offices reported health service disruptions due to ODA cuts.
  • NTD services have been disrupted at levels similar to peak COVID-19.

Climate Change & Emerging Threats

  • Climate change is worsening the NTD burden:
    • Dengue declared a Grade 3 Emergency in 2024:
      • 14 million cases, 10,000 deaths across 107 countries.
      • Geographical expansion of vector-borne NTDs continues.

Public-Private Partnerships

  • Pharma companies have donated US$ 12 billion+ worth of drugs (2011–2025), including: GSK, Pfizer, Sanofi, Merck, Bayer, Novartis, Johnson & Johnson, among others.

Recent Global Action

  • At the 78th World Health Assembly (May 2025):
    • Two NTD-related resolutions adopted:
      1. Eradication of Dracunculiasis (Guinea Worm)
      2. Control of Skin-related NTDs

Way Forward

  • Strengthen nationally owned, sustainable NTD programmes.
  • Ensure alternative funding and service delivery mechanisms.
  • Prevent reversal of hard-won gains and protect vulnerable communities from deeper health inequities.
