Notice to Readers: Final 2009 Reports of Nationally Notifiable Infectious Diseases
Weekly
August 20, 2010 / 59(32);1025-1027-1039


The tables listed in this report on pages 1027--1039 summarize finalized data, as of June 30, 2010, from the National Notifiable Diseases Surveillance System (NNDSS) for 2009. These data will be published in more detail in the Summary of Notifiable Diseases --- United States, 2009 (1). Because no cases of diphtheria, neuroinvasive or non-neuroinvasive western equine encephalitis virus disease, nonparalytic poliovirus infection, severe acute respiratory syndrome-associated coronavirus syndrome, smallpox, and yellow fever were reported in the United States during 2009, these diseases do not appear in these initial tables.

Policies for reporting NNDSS data to CDC can vary by disease or reporting jurisdiction, depending on case status classification (i.e., confirmed, probable, or suspected). The publication criteria used for the 2009 finalized tables are listed in the "Print Criteria" column of the NNDSS event code list, available at http://www.cdc.gov/ncphi/disss/nndss/phs/files/nndss_event_code_list_january_2009_cleared.pdf .

The NNDSS website is updated annually to include the latest national surveillance case definitions approved by the Council of State and Territorial Epidemiologists for enumerating data on nationally notifiable infectious diseases.

Population estimates for the states are from the National Center for Health Statistics. Estimates of the July 1, 2000 through July 1, 2008, U.S. resident population are from the vintage 2008 postcensal series (by year, county, age, sex, race, and Hispanic origin), and are available at http://www.cdc.gov/nchs/nvss/bridged_race.htm. September 2, 2009 population estimates for territories are 2008 estimates from the U.S. Census Bureau (2).
