NCT ID NCT07272122

First seen Jun 26, 2026 · Last updated Jul 30, 2026 · Updated 3 times

Summary

This trial tests whether painting pit latrines with insecticidal paint or adding larvicide to breeding sites can reduce filth fly numbers and diarrhoeal disease in refugee camps in South Sudan. Over 5,600 people will take part across three camps. The study will measure diarrhoea cases in children under 5 and adults over 15, as well as fly counts. If successful, these simple tools could help prevent disease in harsh environments.

Active substance
insecticidal paint (propoxur) and larvicide (diflubenzuron)
What this could lead to
If it works, this could provide a simple, low-cost way to prevent diarrhoeal diseases in refugee camps and other harsh settings.
What could go wrong
This is a large trial but results depend on real-world conditions like weather and camp hygiene. The interventions may not reduce flies enough to lower disease rates.
