Diarrhea has long challenged world health workers. From 1980 to 1995, Healthlink Worldwide published _Dialogue on Diarrhoea_, an international newsletter that provided health workers and managers with practical advice on treating and preventing diarrheal diseases. Produced by the Rehydration Project, this website contains all 60 issues and 16 supplements of the publication over its 15-year run. In addition to providing online access to the newsletter, the site also offers the issues in a downloadable format. Site visitors may also locate specific information by consulting a comprehensive table of contents or by searching the issues by author, subject, or country reference.
