A new online resource highlights interventions for enhancing diarrheal disease control in developing countries. The Enhanced Diarrheal Disease Control Resource Center (www.EDDcontrol.org) includes documents and tools from many key health organizations including WHO, UNICEF, and PATH. The site highlights information on new interventions such as rotavirus vaccines, zinc treatment during diarrheal episodes, and low-osmolarity oral rehydration solution, while also covering time-tested interventions such as breastfeeding and improved sanitation and hygiene. The site was developed by PATH's Rotavirus Vaccine Program (www.rotavirusvaccine.org).
