A major new deworming initiative has been launched to evaluate different strategies to eradicate parasitic worms from communities in Ethiopia.
Initially focusing on the 2 million people who live in the communities of the Wolaita zone in south-east Ethiopia, the project aims to identify the optimal design of programs that will break the transmission of both soil-transmitted helminths (STH) and schistosomiasis infections.
The five-year project will evaluate deworming approaches that seek to ally large-scale drug treatment programs with initiatives that improve water, hygiene and sanitation (WaSH) facilities and practices.
The project is an international collaboration between Imperial College London’s London Centre for Neglected Tropical Disease Research (LCNTDR), World Vision Ethiopia, the Ethiopian Public Health Institute (EPHI) and Ethiopia’s Federal Ministry of Health, with funding from the Children Investment Fund Foundation.
Previous mathematical modelling by the LCNTDR has shown that the transmission of some species of parasitic worms can be broken in certain settings through the provision of multiple interventions, but it has not been attempted at scale in a low-income country through the existing health system.
Professor Sir Roy Anderson, Director of the LCNTDR and Professor of Infectious Disease Epidemiology in the School of Public Health, said: “Our hope is that the findings from this research will be used to inform the design and effectiveness of future government led national deworming projects. Ultimately we want this research to improve the health of millions of people who currently live with these debilitating parasites.”
The innovative project is first of its kind to evaluate the impact of different treatment strategies and WaSH using biometric fingerprint technology to improve coverage and compliance of the interventions.
Biometric fingerprint technology will enable accurate identification and tracking of the estimated 200,000 individuals who will receive deworming tablets during the first year of the project. Creating a register of all those living in the Wolaita zone who comply with treatment is crucial for the monitoring of treatment progress over the course of the project.
Dr Anna Phillips, Senior Project Coordinator, said: ‘To answer the challenging research questions that this project poses we’ll be employing a range of ‘state of the art’ epidemiological methods including new diagnostics, remote data recording, sophisticated analysis methodologies to estimate key epidemiological parameters and various novel methods to track treatment coverage. This data collected will then be interrogated with the aid of mathematical models to inform current and future parasite control policies.’
During the project, LCNTDR will provide technical support and capacity building to EPHI in the evaluation of the project. Together the evaluation team will then be responsible for interpreting and documenting the findings from Gashiyaro.
The implementation of deworming during the project will be conducted by The Federal Ministry of Health, with World Vision Ethiopia leading on the WaSH infrastructure and behaviors change communication activities and the fingerprint technology provided by Simprints.
