Trial ID: NCT05372068


This randomized trial in rural Bangladesh will measure whether installing concrete floors in households with soil floors reduces child enteric infection. The trial will randomize eligible households to receive concrete household floors or to no intervention and measure effects on child soil-transmitted helminth infection, diarrhea, and other enteric infections. The study will collect longitudinal follow-up measurements at birth and when children are ages 3, 6, 12, 18, and 24 months.
