CWW's role in STH control has expanded from drug donation to encompass four main pillars of work, including country support. Our country support work focuses on building capacity, monitoring and evaluation, breaking the cycle of transmission, and linking governments with NGOs.
Country Support
We are committed to supporting comprehensive control of soil-transmitted helminthiasis (STH) in endemic countries. When we formed in 2006, our primary focus was the management of Johnson & Johnson’s donation of Vermox™ (mebendazole). That focus included providing technical country support to ministries of health and education, which we continue to do today.


Building Capacity

  • Through regional technical assistance workshops, we work with multiple countries in the African, Asian, Latin American and the Caribbean regions to build capacity for planning, implementing, monitoring and evaluating STH control efforts; these workshops have also been an opportunity for countries to share lessons learned and explore new strategies.
  • We also support countries in the initial planning phases of their deworming programs; with funds from the Izumi Foundation, we worked with the Pan-American Health Organization (PAHO) to implement a baseline survey in Bolivia. CWW provided funding and worked with PAHO to conduct a similar baseline survey in Paraguay.

Monitoring and Evaluation

  • We support monitoring and evaluation of well-established STH control programs, such as in Cambodia and Bangladesh, where we worked with the Ministries of Health to implement treatment coverage validation surveys to improve results of future deworming campaigns.
  • In Cape Verde and Uganda, we worked with the Ministries of Health and Education to implement a follow-up survey to assess STH prevalence and intensity rates after several years of deworming campaigns.

Breaking the Cycle of Transmission

  • From the very beginning, CWW advocated for comprehensive control of STH to break the cycle of transmission. We developed the WASHED (Water, Sanitation, Hygiene Education and Deworming) Framework, which emphasizes the importance of combining deworming with WASH activities.
  • In Cameroon, we worked with the World Wildlife Fund to support the implementation of the WASHED Framework in the Lobéké area.
  • In Cambodia, we partnered with the Helen Keller International and the Ministries of Health and Education to develop a national school curriculum to teach children how to prevent worm infections.
  • In Nicaragua and Paraguay, with the support of the Izumi Foundation and CWW national STH control program are training teachers to communicate important lessons about STH prevention.

Linking Governments with NGOs

CWW recognizes the critical role of non-governmental organizations (NGOs) at all levels (local, national, and global) of the STH control effort.

  • We quantified the contributions of NGOs to the global deworming effort through the Global NGO Deworming Inventory.
  • CWW was also instrumental in establishing the STH/Schistosomiasis NGDO Coordination Group as part of the NTD NGDO Network.
