The TUMIKIA Project aims to determine whether combining school- and community-based deworming is more effective at controling and eliminating soil-transmitted helminths (STH or intestinal worms) in Kenya than school-based deworming alone. The trial will strengthen the evidence base surrounding STH control and elimination. TUMIKIA stands for ‘Tuagamize Minyoo Kenya Imarisha Afya,’ which means “eradicate worms in Kenya to improve health,” in Swahili.

Background and study design

TUMIKIA endline survey team 2017Approximately 15 million Kenyans are estimated to be infected with STH – hookworm, Ascaris and Trichuris – and more than 5 million of them are children. The Government of Kenya is committed to eliminating STH following the current control strategy recommended by the World Health Organization: annual treatment of all school-aged children using albendazole or mebendazole. In Kenya, the National School-Based Deworming Programme (NSBDP) dewormed 5.9 million children aged 2-14 in 2012-2013 and 6.4 million children in 2013-2014 for STH. Building on this success, the Government of Kenya plans to reach other members of the community also infected with STH, building on the government’s recent successes in using community health workers to deliver simple health interventions.

The two-year trial will provide the drug albendazole to all residents from 150 communities in two areas: Kwale County on the coast and Busia and Siaya counties in western Kenya. There are three study groups:

  • Base: annual school-based deworming (ages 2-14)
  • Increased coverage: annual school- and community-based deworming (ages 2-99)
  • Increased coverage and frequency: bi-annual school- and community-based deworming (ages 2-99)

The TUMIKIA Project is a collaboration between Kenya Medical Research Institute (KEMRI), London School of Hygiene & Tropical Medicine, Imperial College LondonEvidence Action’s Deworm the World Initiative in Kenya, the Ministry of Health, and the Ministry of Education, Science and Technology.
This trial is part of a growing commitment to control NTDs as outlined in new funding commitments announced at a summit meeting in Paris in April 2014. The Bill & Melinda Gates Foundation also announced a new STH strategy which provides a framework for this trial.


The TUMIKIA Project is possible thanks to generous funding from The Bill & Melinda Gates Foundation with additonal support from the Children’s Investment Fund Foundation and the Wellcome Trust.
