—: No reported cases — The reporting jurisdiction did not submit any cases to CDC.
* The rate is calculated using population less than 1 year of age.
† Reportable in <25 states.
§ Total number of reported laboratory-positive dengue cases, including all confirmed cases [by anti-dengue virus (DENV) molecular diagnostic methods or seroconversion of anti-DENV IgM] and all probable cases (by a single, positive anti-DENV IgM).
¶ The rate is calculated using population less than 5 years of age.
** Chronic hepatitis B and C data are not included in NNDSS tables but reported case counts are included in the annual Summary of Viral Hepatitis, published online by CDC's Division of Viral Hepatitis, available at https://www.cdc.gov/hepatitis/statistics/2015surveillance/index.htm.
†† The rate is calculated using population less than 2 years of age.
§§ The rate is calculated using population less than 18 years of age.
¶¶ Includes Escherichia coli O157:H7; shiga toxin-positive, serogroup non-O157; and shiga toxin positive, not serogrouped.
*** Includes syphilis of all stages, including cases where stage of syphilis is not stated.
††† Data reported to ArboNET using the national surveillance case definition for congenital Zika virus disease or infection (CSTE Position Statement 16-ID-01). Additional data reported to the US Zika Pregnancy Registry for outcomes of pregnancies with laboratory evidence of possible Zika virus infection are available at https://www.cdc.gov/zika/reporting/pregnancy-outcomes.html. Cases reported to the US Zika Pregnancy Registry might not meet the national surveillance case definition for congenital Zika virus disease or infection.

Notes:

These are annual cases of selected infectious national notifiable diseases from the National Notifiable Diseases Surveillance System (NNDSS). NNDSS data reported by the 50 states, New York City, the District of Columbia, and the U.S. territories are collated and published. Cases are reported by state health departments to CDC weekly. Because source datasets may be updated as additional information is received, statistics in publications based on that source data may differ from what is presented in these tables.
The list of nationally notifiable infectious diseases and conditions for 2016 and their national surveillance case definitions are available by navigating to the Surveillance Case Definitions | CDC web page, selecting "2016" for the notifiable condition list year, checking "infectious" conditions, and clicking "Get Notifiable List by Year". This list incorporates the Council of State and Territorial Epidemiologists (CSTE) position statements approved in 2015 by CSTE for national surveillance, that were implemented in January 2016, including updated surveillance case definitions for acute hepatitis C and chronic hepatitis C virus infections. 2016 data are reported through June 30, 2017. Publication criteria for the finalized 2016 data are available at /nndss/documents/2016_NNDSS_Publication_Criteria.pdf. See also Guide to Interpreting Provisional and Finalized NNDSS Data.
Population estimates for incidence rates are July 1st, 2016 estimates obtained from the National Center for Health Statistics (NCHS) postcensal estimates of the resident population of the United States for July 1, 2011 - July 1, 2016, by year, county, single year of age (range: 0 to 85 years), bridged-race (white, black or African American, American Indian or Alaska Native, Asian, or Pacific Islander), Hispanic ethnicity (not Hispanic or Latino, Hispanic or Latino), and sex (Vintage 2016), prepared under a collaborative arrangement with the U.S. Census Bureau. Population estimates for states as of June 26, 2017 are available at https://www.cdc.gov/nchs/nvss/bridged_race/data_documentation.htm. Population estimates for territories are the 2016 mid-year estimates from the U.S. Census Bureau International Data Base accessed on July 24, 2017 at https://www.census.gov/population/international/data/idb/informationGateway.php. The choice of population denominators for incidence is based on the availability of population data at the time of publication preparation.
Annual tables for 2016 and later years are available on CDC WONDER.
Annual summary reports from 1993-2015 are available as published in the MMWR.
NNDSS annual tables since 1952 are available at CDC Stacks (once in CDC Stacks select "Annual Reports" in the "Genre" box to the left).
