Stopping Parasites from the Floor Up

Enteric parasites transmitted via soil are a major contributor to disease worldwide, but a simple household intervention—finished flooring—may reduce their prevalence, according to a new study in rural Bangladesh and Kenya.
Living in a household with finished floors—such as those made of concrete— was associated with a lower risk of disease via soil-transmitted helminths and Giardia duodenalis among 2–16-year-olds

Unlike WASH (water, sanitation, and hygiene) interventions, finished floorings require minimal sustained behavior changes and are easily maintained.
It’s not the first study to draw such a conclusion: Earlier research out of Mexico reported a 21% reduction in parasite count among households whose dirt floors were fully replaced by concrete floors.
