Notice to Readers Changes in National Notifiable Diseases and Mortality Data Presentation

This issue of MMWR incorporates modifications to Tables I-III, Cases of Notifiable Diseases, United States, and to Table IV, Deaths in 121 U.S. Cities. This year, the purposes of the notifiable disease modifications are to add nationally notifiable diseases recently designated reportable in 25 states and to group selected vaccine-preventable diseases. Except where otherwise indicated, the data presented in the notifiable disease tables are transmitted to CDC through the National Electronic Telecommunications System for Surveillance (NETSS).

Table I. For the infectious diseases added during 1995 to the list of nationally notifiable diseases that are reportable in 25-39 states, data will now be included in Table I; these diseases are post-diarrheal hemolytic uremic syndrome and invasive group A streptococcal disease. Because not all nationally notifiable diseases are reportable in every state or territory, the reported number of cases of some diseases in Table I represent only the totals from states or territories in which the diseases are reportable.

Tables II and III. Although not all disease caused by different serogroups of Neisseria meningitidis are preventable by vaccination, the currently available polysaccharide vaccine is used to control outbreaks caused by vaccine-preventable serogroups. Conjugate vaccines designed for potential use in routine infant vaccination programs for the prevention of disease caused by selected serogroups (e.g., serogroup C) are also being evaluated; therefore, reports of meningococcal disease will be moved from Table II to Table III.

Table IV. The reporting area of Madison (Dane County), Wisconsin, will no longer be included in the 121 Cities Mortality Reporting System. Because of the large catchment area for Dane County, Wisconsin, it will be replaced by two county reporting areas: Boise (Ada County), Idaho, and Lansing (Ingham County), Michigan. Therefore, Table IV will contain 122 cities and will be renamed "Deaths in 122 U.S. Cities."
