Village-based educational sessions (Ed) were conducted in all three study arms at baseline, then every four months in the elimination study arm, and annually in the control study arm in conjuction with intervention activities. Education alone was conducted annually in the negative control study arm. Initial Vicious Worm workshops (VWorm) were conducted in one primary school in each of the three study arms in 2016, and follow-up sessions were conducted one year later. Assessment questionnaire 1 (QS1) was used in the elimination study arm workshops, while the revised QS2 was used in the control and negative control study arms.
