Last century, the invention of the outhouse helped to eliminate hookworm and other parasites in the United States. Now new research shows that the lowly latrine could be a powerful tool in controlling these diseases, which remain widespread among the world’s poorest people.
It’s pretty simple. Whether people use it or just have access to it, the latrine could help save hundreds of millions of people from disabling disease. So concludes researchers from the Swiss Tropical and Public Health Institute, who found that in study sites, latrines halved the risk of infection from three common intestinal parasites- hookworm, roundworm and whipworm. Their research was published earlier this week in PLoS Medicine.
Hookworm, roundworm and whipworm– known collectively as the soil-transmitted helminthes or STH’s- are transferred from person to person through contact with feces-contaminated soil. It makes sense then that latrines or toilets would have a major impact on reducing transmission. This isn’t exactly a new idea. Today STH’s are most common in developing countries where there is limited access to clean water and basic sanitation. It wasn’t that long ago though that STH’s were a major problem here in the US, especially in the American South. It was the invention of the outhouse, in combination with anti-helminthes treatments, that helped eradicate these diseases. Continue reading
