We are helping put deworming and a world free of worms on the global agenda.

Accelerating treatment to cover the at-risk school-age children in the highest-burden countries is the most cost-effective and efficient way to achieve the WHO goal of 75% coverage of school-age children. 

This is where we focus. 

The Deworm the World Initiative scales school-based deworming in these high-need geographies. 

We have expanded our  technical assistance support to a national school-based deworming program in India and Ethiopia, and started work in Nigeria and Vietnam, while maintaining technical support in Kenya and states in India were we have previously worked. 


Where we Work


  • Our India team provides technical assistance to eight states: Bihar, Rajasthan, Madhya Pradesh, Uttar Pradesh, Jharkhand, Chhattisgarh, Telangana, and Tripura.
  • In February 2015, we helped the national government initiate the now-twice-annual National Deworming Day (NDD). The government reported treatment of 140 million children in the first round of the program. 
  • In 2016, NDD was expanded to all 36 states and union territories in India, targeting 220 million children for school-based and anganwadi-based (preschool) treatment for STH. The Government of India reports that the program has treated 179 million children in February 2016. 
  • In August 2016, a second round of treatment took place in states where high prevalence indicates a need for twice-annual treatment. 


  • Thrive Networks is our partner in Vietnam. The program there supports deworming in four provinces. The program has achieved over 90% coverage in its first round of treatment this year with another round underway at the end of 2016. We are also planning an RCT to evaluate the effects of a hygiene intervention on worm infections in 2017.  


  • We’re entering our fifth year at national scale in Kenya. The Government of Kenya’s National School Based Deworming Program routinely treats ~ 6 million children for both STH and schistosomiasis. Year 3 results were released during the first week of March 2016 in this booklet. 6.1 million children were treated. Year 4 results will be released in early 2017. 


  • In Ethiopia, we partner with the Schistosomiasis Control Initiative (SCI) in supporting the Federal Ministry of Health’s national school-based deworming program. The program is projected to distribute over 100 million deworming treatments to school-age children over the next five years.


  • Nigeria is second to India in its number of children at risk for intestinal worm infections. In 2015, we conducted an opportunity analysis and exploratory visits to four state governments in Nigeria, with the aim of determining which could be a good starting point for our support there.
  • In early 2016, we started providing technical assistance for school-based deworming in Cross River state with a partner organization (RTI) that supports community-based treatment for other endemic NTDs in the state. We are now pursuing expansion into three additional states to scale up treatment of STH and schistosomiasis.
