††† 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.
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.
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
Population estimates for territories are the 2016 mid-year estimates from the U.S. Census Bureau

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
NNDSS annual tables since 1952 are available at CDC Stacks
