Neglected Tropical Diseases (NTDs)

The common features of NTDs are that they:

  • Disproportionately affect the poor, often in marginalised communities and conflict areas
  • Are mostly found in tropical and subtropical countries
  • Are relatively neglected by research in terms of financial investment

Social stigma is a major consequence of NTDs, hampering people’s ability to work, attend school and thrive within their families and communities. For this reason, NTDs can negatively impact the development of the world’s poorest communities and countries.

More than 1 billion people — one-sixth of the world’s population — suffer from one or more NTDs.


They are disfiguring, debilitating, and sometimes deadly infectious diseases that are the source of tremendous suffering in low-and-middle-income countries.
