Supporting collaboration for sustainable STH programs
The STH Coalition is a global platform that brings together partners across the soil-transmitted helminthiasis (STH) community to support collective decision-making and coordinated action as programs navigate a period of significant transition.
As STH programs move from a model of externally supported scale-up toward greater country ownership and long-term sustainability, the Coalition provides a space for partners to align on priorities, interpret emerging challenges, and move forward together. The Coalition supports shared understanding across stakeholders, strengthens coordination across actors, and helps translate complexity into practical, program-relevant action.
Our Vision
A global STH community that works together effectively to sustain progress and support sustainable country-led programs.

STH Overview
Soil transmitted helminthiasis (STH), or intestinal worm infections, affect communities across 84 countries worldwide, threatening the health and development of nearly 883 million children and 247 million women who require treatment globally. In children, these infections cause anemia, malnutrition, growth stunting, and cognitive impairment, undermining school attendance, learning, and long-term development.
Over the past two decades, global partnerships have made major progress in reducing disease burden through large-scale deworming efforts. However, the global STH landscape is now entering a period of significant transition. As funding models evolve, partners across the community must work together to sustain progress and protect the gains achieved to date.
