Summary of Notifiable Diseases
United States 2003
Data Sources
Provisional data concerning the reported occurrence of notifiable diseases are published weekly in the MMWR. After each reporting year, staff in state health departments finalize reports of cases for that year with local or county health departments and reconcile the data with reports previously sent to CDC throughout the year. These data are compiled in final form in the Summary.
Notifiable disease reports are the authoritative and archival counts of cases. They must be approved by the appropriate epidemiologist from each submitting state or territory before being published in the Summary. Data published in MMWR Surveillance Summaries or other surveillance reports produced by CDC programs might not agree exactly with data reported in the annual Summary because of differences in the timing of reports, the source of the data, or surveillance methodology.
Data in the Summary were derived primarily from reports transmitted to the Division of Public Health Surveillance and Informatics, Epidemiology Program Office, CDC, from health departments in the 50 states, five territories, New York City, and the District of Columbia. More information regarding notifiable diseases, including case definitions for these conditions, is available at http://www.cdc.gov/ncphi/disss/phs.htm. Policies for reporting notifiable disease cases can vary by disease or reporting jurisdiction.
Final data for certain diseases are derived from the surveillance records of the following CDC programs. Requests for further information regarding these data should be directed to the appropriate program.
National Center for Health Statistics (NCHS)
Office of Vital and Health Statistics Systems (deaths from selected notifiable
diseases).
National Center for Infectious Diseases (NCID)
Division of Bacterial and Mycotic Diseases (toxic-shock syndrome; streptococcal disease, invasive, group A; streptococcal toxic-shock syndrome.
Division of Vector-Borne Infectious Diseases (ArboNET surveillance data regarding arboviral encephalitis/meningitis).
Division of Viral and Rickettsial Diseases (animal rabies, hantavirus pulmonary syndrome, and severe acute respiratory syndrome [SARS]).
National Center for HIV, STD, and TB Prevention (NCHSTP)
Division of HIV/AIDS Prevention --- Surveillance and Epidemiology (acquired immunodeficiency syndrome [AIDS] and human immunodeficiency virus [HIV] infection).
Division of STD Prevention (chancroid, chlamydia, gonorrhea, and syphilis).
Division of TB Elimination (tuberculosis).
National Immunization Program (NIP)
Epidemiology and Surveillance Division (poliomyelitis).
Disease totals for the United States, unless otherwise stated, do not include data for American Samoa, Guam, Puerto Rico, the U.S. Virgin Islands, or the Commonwealth of the Northern Mariana Islands.
Population estimates for the states are derived from CDC’s National Center for Health Statistics (NCHS) census populations with bridged race categories, vintage 2003 postcensal series by year, county, age, sex, race, and Hispanic origin for July 1, 2000--July 1, 2003 (http://www.cdc.gov/nchs/about/major/dvs/popbridge/popbridge.htm). For sexually transmitted diseases, population estimates are derived from the vintage 2002 postcensal series by year, county, age, sex, race, and Hispanic origin for July 1, 2000--July 1, 2002. The choice of population denominators for incidence rates reported in the MMWR is based on 1) the availability of census population data at the time of preparation for publication and 2) the desire for consistent use of the same population data to compute incidence rates reported by various CDC programs. Incidence rate in the Summary is calculated as the number of reported cases for each disease or condition divided by either the U.S. resident population for the specified demographic population or the total U.S. residential population, multiplied by 100,000. When a nationally notifiable disease is associated with a specific age restriction, the same age restriction is applied to the population in the denominator of the incidence calculation. In addition, population data from states in which the disease or condition was not notifiable or was not available were excluded from incidence calculations.
