Effectiveness of Zinc in the Treatment of Diarrhea in India, Mali, and Pakistan

In 2004, WHO and UNICEF issued a joint statement recommending zinc for the treatment of acute diarrhea along with oral rehydration therapy. In support of the implementation of this recommendation, the introduction of this intervention was initiated in Mali, India, and Pakistan. 

In a community-based, controlled trial, activities evaluate whether adding zinc as a therapeutic modality for diarrhea delivered through existing channels (including at the village level) to the current case management package for under-five children results in:

  • reduction in visits to health care providers for treatment of illness 
  • reduction in drug use (i.e., antibiotics and other drugs during diarrheal illnesses) 
  • an increase in ORS use during diarrhea in the intervention communities

In addition to funding from USAID via the GRA, funding for local costs, including training of health workers and hiring interviewers for household surveys, is provided through grants from the World Health Organization-Department of Child and Adolescent Health and Development to the organizations implementing the studies in India, Pakistan (Aga Khan University), and Mali (Save the Children/Mali).
