Soil testing to track intestinal worm infections

Soil epidemiology: a new tool for environmental surveillance of soil-transmitted helminth infections in endemic settings.

NIH-funded research University of California Berkeley · NIH-11136532

What this research studies

From your perspective, researchers will take soil samples from places where people gather, like home entrances, water points, and schools, and test them for worm eggs using lab techniques. They will compare those soil results to human stool testing done with sensitive qPCR methods as part of a large deworming project in communities in Benin and India. The work links environmental sampling with human infection data to find whether soil testing could be a less invasive, lower-cost way to spot ongoing transmission. The project uses samples collected across many communities over time to check how well soil sampling matches human infections after mass drug administration.

Who could benefit from this research

Good fit: People living in soil-transmitted-helminth (intestinal worm) endemic communities—especially those taking part in community deworming programs in the trial areas—who can provide stool samples or allow soil sampling near their homes or local sites.

Not a fit: People who do not live in endemic areas, are not part of the participating communities, or are unwilling to provide stool samples or allow soil collection likely would not benefit directly from this work.

Why it matters

Potential benefit: If this works, programs could monitor worm transmission with less invasive and cheaper methods, helping target treatment and reduce reinfection.

How similar studies have performed: Human stool testing and community-wide deworming have shown promise in trials and models, but using soil sampling for surveillance is relatively new with only early promising results.
