Summary of Notifiable Diseases
United States 2002
Preface
The Summary of Notifiable Diseases, United States, 2002 contains the official
statistics, in tabular and graphic form, for the reported occurrence of
nationally notifiable diseases in the United States for 2002. The data
are final totals for 2002 reported as of June 30, 2003, unless otherwise
noted. These statistics are collected and compiled from reports sent by
state health departments to the National Notifiable Diseases Surveillance
System (NNDSS), which is operated by CDC in collaboration with the Council
of State and Territorial Epidemiologists (CSTE).
The Summary is located on the Internet at http://
www.cdc.gov/mmwr/summary.html.
This site also includes publications from past years.
The Highlights section presents noteworthy epidemiologic or prevention information
for 2002 for selected diseases and additional information to aid in the interpretation
of surveillance and disease-trend data.
Part 1 contains tables showing incidence data for each of the nationally notifiable
diseases during 2002.* The tables provide the number of cases reported to CDC
for 2002, as well as the distribution of cases by month, geographic location,
and by patient's age, sex, race, and Hispanic ethnicity. Nationally notifiable
diseases that are reportable in <40 states do not appear in these tables.
Part 2 contains graphs and maps that depict summary data for many of the notifiable
diseases described in tabular form in Part 1. Part 3 contains tables that list
the number of cases of notifiable diseases reported to CDC since 1970. This section
also includes a table enumerating deaths associated with specified notifiable
diseases reported to the National Center for Health Statistics (NCHS), CDC, during
1996-2000.†
The Selected Reading section presents general and disease-specific references
for notifiable infectious diseases. These references provide additional information
on surveillance and epidemiologic issues, diagnostic issues, or disease control
activities.
*Because no cases of paralytic poliomyelitis and western equine encephalitis
were reported in the United States during 2002, these diseases do not appear
in the tables in Part 1.
†In 1999, mortality data began to be coded according to
the International Statistical Classification of Diseases and Related
Health Problems, Tenth Revision. To bridge the mortality data for
the period 1996-1998 (deaths coded using the International Classification
of Diseases, Ninth Revision), and 1999-2000, we use comparability ratios
provided by the National Center for Health Statistics.
