Oral rehydration solution (ORS)—a mixture of water, sugar, and salt that is administered as part of oral rehydration therapy (ORT)—is credited with preventing tens of millions of deaths from cholera and other diarrheal diseases. In this week's podcast you'll hear from two scientists who helped bring this simple, low-tech, and cost-effective treatment into worldwide use. Richard Cash, senior lecturer on global health at Harvard T.H. Chan School of Public Health, and David Nalin, professor emeritus at Albany Medical College, collaborated on groundbreaking clinical studies showing that ORT was remarkably effective in reversing dehydration.
