Plain English Summary

Background and study aims
Soil-transmitted helminths (STH), including hookworm, roundworm and whipworms, are common intestinal infections in Kenya. Global estimates indicate that more than 1.4 billion people are infected with at least one STH species. They cause anaemia, gastro-intestinal problems, tiredness amongst other symptoms. The most affected and at-risk populations are school children and these infections impede their physical growth and cognitive development, contributing significantly to school absenteeism. The current control strategy recommended by the World Health Organization (WHO) is yearly treatment of children with a single-dose treatment of albendazole. However, after treatment, reinfection can occur if the environment remains contaminated with infective eggs/larvae. In this research, we want to learn more about new ways to detect eggs/larvae in stool.

Who can participate?
Children attending classes 1-6 who are aged 5-15 years will be randomly selected to participate. In total we will recruit 1,354 school children.

What does the study involve?
We will take a small stool sample from the study participants to find out whether they are infected with worms or not. We will also provide a questionnaire to learn about the households of the participants, deworming medication used and the availability and use of safe water and sanitation. We will also map participant’s houses in order to help locate the household during follow-up visits.

What are the possible benefits and risks of participating?
All infected individuals will receive deworming treatment recommended by the ministry of Health. Participants may be uncomfortable providing stool samples for worm screening.

Study information

Scientific title

Evaluation of the diagnostic performance of a mobile digital technology for the detection and quantification of soil-transmitted helminths among school children in Kenya


Study hypothesis

The diagnostic performance of a modified version of KK technique which entails; visualization of the sample through (1) a mobile phone coupled to the ocular of the microscope and (2) a web-based telemicroscopy platform is as sensitive as conventional visual analysis using only optical microscopy, as it is done in conventional KK technique

Helminth infection


This study will be a school-based cross-sectional survey among school children (5-15 y) conducted to determine the prevalence of STH among this age group. This study will be conducted over 1 y.

In each school eligible children with signed informed consent [class/grade 1-6, age (5-15 y)] will be randomly selected and tested for the presence of STH.

To determine the performance of the SpotLab technology in assessing the treatment efficacy of albendazole, 250 STH positive children will provide 2 consecutive days stool sample before and 21 days after treatment.
