Results & Impact


More than 1.6 billion people are at risk of painful, disabling Neglected Tropical Diseases (NTDs). Many people living with NTDs are stigmatized, are absent from or cannot participate fully in school, or are unable to find work putting them at greater risk of poverty.


USAID is working to address five of the most burdensome NTDs that are preventable and treatable with safe, effective medicines.


USAID works alongside countries to achieve the elimination of lymphatic filariasis, trachoma, and onchocerciasis in supported countries.

Since 2006, 13-USAID supported countries have eliminated at least one NTD—and more disease eliminations are fast approaching.

0 Countries
Within 5 years, USAID’s goal is for more than 15 countries to eliminate one of these three NTDs:
0 Countries
To eliminate lymphatic filariasis
0 Countries
To eliminate blinding trachoma
0 Countries
To eliminate river blindness

USAID also works with 11 countries for treatment of intestinal worms and 10 countries for treatment of schistosomiasis.


Since 2006, USAID has worked alongside more than 30 countries to fight these diseases and strengthen health systems to respond to them long-term.


Considered a “best buy” in global health, U.S. investments to end NTDs are highly effective. The results below were supported by USAID.
