Notice to Readers Availability of Case Definitions for Infectious Conditions under Public Health Surveillance on Internet

The 1997 MMWR Recommendations and Reports, Case Definitions for Infectious Conditions under Public Health Surveillance (1), is now available on the Internet. This document provides updated uniform criteria for state health department personnel to use when reporting notifiable diseases to CDC. The reported numbers of cases of selected notifiable diseases are printed each week in Tables I-III of MMWR.

Since May 2, 1997, the complete document has been available as a .pdf file (Adobe Acrobat portable document format) from CDC's MMWR World-Wide Web (WWW) page and from CDC's file transfer protocol server at In response to high demand from state and local health departments, case definitions for specific conditions are now accessible individually from the Case Definitions for Infectious Conditions under Public Health Surveillance WWW site at other/case_def/about.html. To facilitate analysis of historical surveillance data, the original case definitions from the 1990 publication Case Definitions for Public Health Surveillance (2) and intermediate revisions are linked at this website to their 1997 revised versions. Revisions to these case definitions will be added to this WWW site when approved by the Council of State and Territorial Epidemiologists.
