The US National Center for Infectious Diseases, Center for Disease Control, offers the full text of its quarterly, peer reviewed journal Emerging Infectious Diseases at its web site. The issues are divided into three categories: Perspectives, dealing with the underlying causes of infectious disease emergence; Synopses, summaries of specific diseases; and Dispatches, "brief laboratory or epidemiologic reports with an international scope." The October-December 1996 issue contains articles on protecting against dangerous emerging pathogens, "Molecular Mechanisms of Bacterial Virulence," and Creutzfeldt-Jacob Disease in the US, among others. Issues are available in HTML, ASCII, .pdf, and PostScript format. A limited number of issues are available in Spanish, French and Chinese.
