Sexually Transmitted Disease Morbidity
United States, Guam, Puerto Rico, and Virgin Islands,
by Gender, 1984 - 2014

Summary:    This dataset contains Sexually Transmitted Disease (STD) morbidity case reports reported to the National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP), Centers for Disease Control and Prevention (CDC). The number of cases and disease incidence rates are reported by year, gender of patient, type of STD, and area of report.
Population:    Disease reports are from the 50 United States and D.C., Puerto Rico, Virgin Islands and Guam. See Data Source Information for more about the denominator population data sources.
Source:    Centers for Disease Control and Prevention, Sexually Transmitted Disease Surveillance. The latest CDC STD published surveillance reports are available at STD Surveillance and Statistics.
In WONDER:    You can produce tables, maps, charts, and data extracts. Obtain incidence counts and rates, and select specific disease and demographic criteria to produce cross-tabulated incidence measures. You can limit and index your data by any and all of the variables.

Please refer to the following topics:


STD Morbidity Data Request

Output:    You can produce tables, maps, charts, and data extracts.

Variables:    You can limit and index your data by any and all of these variables:

  1. Disease
  2. Gender
  3. Regional multi-state groups:
    STD reporting regions
    MMWR reporting regions
    HHS regions
  4. State and outlying areas
  5. Year
How?    The Request screen has sections to guide you through the making a data request as step-by-step process. However, to get your first taste of how the system works, you might want to simply press any Send button, and execute the default data request. The data results for your query appear on the Table screen. After you get your data results, try the Chart and Map screens. Or export your data to a file (tab-delimited line listing) for download to your computer.

For more information, see the following:

Quick Start Guide
Step 1, Organize and label results
Step 2, Select location
Step 3, Select disease, year and gender
Step 4, Other options

'By-Variables'    Select variables that serve as keys (indexes) for organizing your data. See How do I organize my data? for more information.
Note:    To map your data, you must select at least one geographical location as a "By-Variable" for grouping your data, such as State.
Help:    Click on any button labeled "Help", located to the right hand side of the screen at the top of each section. Or click on any label, such as the "Group Results By" label.
Send:    Sends your data request to be processed on the CDC WONDER databases. The Send buttons are located on the bottom of the Request page, and also in the upper right corner of each section, for easy access.



Step 1. Organize table layout:

Group Results By   Select up to five variables that serve as keys for grouping your data. See Group Results By below for hints.
Title   Enter any desired description to display as a title with your results.

The following statistical measures are available as query results:

  1. Counts
  2. Rates


Group Results By...

Select up to five variables that serve as keys for grouping your data. For example, you could select to group (summarize, stratify, index) your data by State and by Year, to compare each the disease reports by state for each year.

How?   

Hints:   

  1. About charts:
    You cannot make charts when your data has more than two By-Variables.
  2. About maps:
    To make a map, you must request data grouped by a geographic location variable, such as State, as the first By-Variable. Then click the Map tab after you obtain the data results.
  3. About regions:
    You can only select one type of regional area division for a data request. For example, if you select to group the data by HHS regions, then you cannot also group the data by MMWR regions in the same request. However, you can also group the data by State.
  4. When data is grouped by Region (when Region is selected as a By-Variable) then the data includes US and outlying areas.
  5. About diseases:
    Because the denominator populations used for calculating rates vary among the different diseases, you must select Disease as one of the indexes when your request is limited to more two or more specific diseases. If you are selecting more than one disease, then select Disease as a By-Variable.

Counts

Counts show the sum or the frequency incidence of STD disease case reports, for the selected categories in the data request.


Rates

The rates are calculated as the incidence of STD disease reports, divided by the population, and then the result is multiplied by 100,000 to indicate the rate per so many persons.

Hints:  
  • You must group data by Disease to show rates when more than 1 disease is selected.
  • You can select the factor for rates in the Other options section on the data request screen. The default factor is per 100,000 persons.

Notes:  

  • To see Rate and Population for more than one disease, you must also group by Disease. Rates are not reported when data are combined for disease categories, because the reporting populations vary for different diseases. For example, the denominator population for Congenital Syphilis is the number of live births. See Reporting Issues for more information.
  • The phrase Not Applicable is shown when the denominator population is not on record, or when the rate cannot be calculated due to lack of disease incidence count or lack of denominator population. Population data are not available for persons of unknown gender.
  • See About Rates in the Additional Information section below.

Step 2. Select location:
Click a button to choose locations for States and outlying areas or Regions. You can limit to your data request to items in only one of these categories. However, you can group the data report by another location type, to show a row for each area.
  1. State and outlying areas
  2. MMWR reporting regions
  3. HHS regions
  4. STD reporting regions

Show Totals:    If checked totals and sub-totals will appear in the results table.
Show Zero Values:    If checked totals and sub-totals will appear in the results table. However, totals are not shown for STD Morbidity when data are grouped by Disease, because the populations shown are disease-specific. See Reporting Issues for more information.
Precision:    Select the precision for rate calculations. When the rate calculated for a small numerator (incidence count) is zero, you may increase the precision to reveal the rate by showing more numbers to the right of the decimal point.
Data Access Timeout:    This value specifies the maximum time to wait for the data access for a query to complete. If the data access takes too long to complete, a message will be displayed and you can increase the timeout or simplify your request. If you can't complete a request using the maximum timeout, contact user support and we will try to run a custom data request for you.
Calculate Rates Per:    This value is the factor for the rate calculation. The default value is per 100,000 persons.

Data Source Information

Data Sources    Disease Incidence Sources:
The data are based on case reports of sexually transmitted diseases submitted by state and local health departments to CDC's Division of STD/HIV Prevention. The data are reported through STD*MIS, the National Electronic Telecommunications System for Surveillance (NETSS) or the National Electronic Disease Surveillance System (NEDSS).

To learn more about the methods and source of these data please refer to:

Current STD Morbidity 1984-2014:   Reports and corrections sent to CDC on hardcopy forms and for NETSS electronic data through June 10, 2015 have been included in the data for years 1984 - 2014. Congenital syphilis cases confirmed through January 2016 are also included, for births through 2014. See also Sexually Transmitted Disease Surveillance 2014.

Population Data Sources:

Due to use of the updated population data, rates may be different from prior or archive data sets.

  • United States state and national population: The national population shown as the denominator for rate calculations is the sum of the state populations for each state reporting diseases in the given year.
    • Data for years 2000-2009, and 2011-2014: 
      The population data used to calculate rates are the National Center for Health Statistics July 1st bridged-race postcensal population estimates for the resident population based on the Census 2000 counts. The population estimates were prepared under a collaborative arrangement with the U.S. Census Bureau and the National Center for Health Statistics. The population estimates are available on the Internet from: http://www.cdc.gov/nchs/nvss/bridged_race.htm. See population details below for more information.
    • Data for year 2010: 
      The population data used to calculate rates are the National Center for Health Statistics April 1st, 2010 bridged-race population estimates for the resident population based on the Census 2010 counts. The population estimates were prepared under a collaborative arrangement with the U.S. Census Bureau and the National Center for Health Statistics. The population estimates are available on the Internet from: http://www.cdc.gov/nchs/nvss/bridged_race.htm. See population details below for more information.
    • Data for years 1990-1999: 
      The population counts for 1990-1999 incorporated the bridged single-race estimates of the April 1, 2000 resident population census. These files were prepared by the U.S. Census Bureau with support from the National Cancer Institute. The July 1st intercensal population estimates are available on the Internet from: http://www.cdc.gov/nchs/nvss/bridged_race.htm.
    • Data for years 1984-1989: 
      For the United States, rates were calculated using two sources:
      1. Bureau of the Census; United States Population Estimates by Age, Sex and Race:1980-1989 [Series P-25, No. 1045]; Washington: U.S. Government Printing Office, 1990] and
      2. United States Population Estimates by Age, Sex and Race: 1989 [Series P-25, No. 1057]; Washington: U.S. Government Printing Office, 1990.
  • Outlying areas: 
    Population estimates for Guam, Puerto Rico, and the Virgin Islands were obtained from the Bureau of Census web site: http://www.census.gov/ipc/www/idb/tables.html.
  • Population data for congenital syphilis rates: 
    Rates of congenital syphilis were calculated using published live birth information (coded by the States and provided to the National Center for Health Statistics (NCHS) through the Vital Statistics Cooperative Program. See population details below for more specific sources for births data.

Morbidity Rates:    The following issues affect the calculation of morbidity rates:
  • The default rate shown is the rate per 100,000 persons. The rate is calculated as the disease incidence count reported, divided by the population, and then the result is multiplied by 100,000 (or the specified factor in the data request criteria).
  • The phrase Not Reported is shown when the specific disease was not reported for the given location and year. Some conditions were not reported for specific locations and years, see Reporting Issues for more information.
  • The phrase Not Applicable is shown when the denominator population is not on record, or when the rate cannot be calculated due to lack of disease incidence count or lack of denominator population. For example, population denominator data are not available for persons of unknown age.
  • Due to the use of updated population data, rates may be different from previously published reports or archive data sets.
  • Unknown and missing values for gender are not redistributed in this data collection, thus the gender specific rates are not comparable to rates calculated where unknown and missing values are redistributed. Gender-specific rates are likely to be under-representative in areas with a high proportion of cases with missing or unknown gender.
  • Rates are reported when data are grouped by disease or when data for a single disease is shown. Populations vary per disease, reporting jurisdiction and year. See Reporting Issues for more information.

About the national population: The denominator population shown for the nation (U.S. total population) is the sum of the annual population for those states reporting the disease. The U.S. denominator population used to compute the overall U.S. rate varies from year to year and from disease to disease, due to changes in reporting status for specific diseases and states. See Reporting Issues and Population Data Sources for more information.

About the inclusion of the number of live births: The denominator population for Congenital Syphilis is the total number of live births in the given year(s). See Population Data Sources for more information.

The denominator population for Total Syphilis does not include live births in the calculation.

Reporting Issues:    Case reports may differ slightly from previously published data due to later revisions.

Electronic versus hardcopy reporting:
Beginning in 2003, all 50 states and DC had converted from summary hardcopy reporting to electronic case-specific reporting via NETSS (with the exception of congenital syphilis, which is still reported on hardcopy forms by several areas). Much of the data in this system are based on aggregated from hardcopy report forms. Form CDC 73.688 is the quarterly form used from 1963 to 2002 to report summary data for all stages of Syphilis, Congenital Syphilis, Gonorrhea, Chancroid, and Chlamydia. Data from this quarterly form are used for this "by gender" data set. Form CDC 73.2638 was used from 1981 to 2002 to report summary data for Primary and Secondary Syphilis, Gonorrhea, and Chlamydia by age, race, and gender. Data from form CDC 73.2638 are used for the "by age group, race and gender" data set.

Reporting entities differed in their ability to reconcile differences in total cases derived from summary hardcopy monthly, quarterly, and annual reports. Thus, there may be discrepancies in the total number of cases between competing data sources.

About Chancroid reporting: Chancroid cases should be interpreted with caution in view of the fact that Haemophilus ducreyi, the causative organism of chancroid, is difficult to culture and, as a result, this condition may be substantially under diagnosed.

About Chlamydia reporting: Before 1996, Chlamydia reporting was voluntary, and thus sporadic. From 1995 - 1999, upstate New York did not report Chlamydia, and thus the total US denominator population for Chlamydia excludes the upstate New York state population for the years 1984 - 1999. However, New York City did report Chlamydia before the year 2000, and thus only the New York City cases and population are represented for Chlamydia rates in New York for years 1984 - 1999.

Since Chlamydia is often without symptoms, the number of cases reported is more a function of the amount of screening done and not the actual incidence. Screening occurs more often for women because Chlamydia is associated with Pelvic Inflammatory Disease and infertility. There is approximately a 4:1 ratio of women to men in Chlamydia case reporting due to screening practices. Refer to Tracking the Hidden Epidemics 2000 - Chlamydia for more information about reporting and gender differences. Traditionally male cases of Chlamydia have not been reported in the MMWR Notifiable Disease Annual Summaries.

States not reporting Chlamydia prior to 1995 are the following:

(1984) Guam, Virgin Islands, Alaska, Alabama, Arkansas, Colorado, Connecticut, Florida, Georgia, Hawaii, Iowa, Louisiana, Massachusetts, Michigan, Minnesota, Mississippi, North Carolina, New Jersey, New Mexico, Oklahoma, Rhode Island, South Dakota, Tennessee, Texas, Vermont, Washington, West Virginia, Wyoming

(1985) Alaska, Arkansas, Colorado, Connecticut, Florida, Massachusetts, Minnesota, Mississippi, North Carolina, New Jersey, New Mexico, Oklahoma, Tennessee, Texas, Virginia, Vermont

(1986) Alabama, Colorado, Connecticut, Florida, Michigan, Mississippi, North Carolina, New Jersey, New Mexico, Tennessee, Virginia, Vermont, Washington

(1987) Alaska, Alabama, Colorado, Florida, Michigan, Mississippi, North Carolina, New Mexico, Tennessee, Virginia, Vermont

(1988) Alaska, Alabama, Colorado, Florida, Michigan, Mississippi, North Carolina, New Jersey, Virginia, Vermont

(1989) Alabama, Colorado, Florida, Michigan, Mississippi, New Jersey, Vermont

(1990) Alaska, Alabama, Colorado, Michigan, New Jersey, Pennsylvania

(1991) Alaska, Alabama, Florida, Michigan, Mississippi

(1992) Alaska, Alabama, Florida, Mississippi

(1993) Alaska, Alabama, Florida, Mississippi (1994) Alaska, Florida, Mississippi

(1995) Alaska
About Gonorrhea reporting:  In 1984, Gonorrhea was not reported by Guam or the Virgin Islands. Guam and the Virgin Islands are not included in the denominator population " for the total U.S. and territories, when Gonorrhea rates for 1984 are shown.

In 1994, Gonorrhea was not reported by Georgia. Georgia is not included in the total US denominator population, when Gonorrhea rates for 1994 are shown.

About Syphilis reporting:  Total Syphilis for a given year is the sum of reported cases for Primary Syphilis, Secondary Syphilis, latent (including neurosyphilis, Early Latent, Late and Late Latent, late with clinical manifestation other than neurosyphilis, and unknown latent) and Congenital Syphilis combined.

The disease category Late and Late Latent Syphilis includes cases of late latent syphilis, latent syphilis of unknown duration, neurosyphilis, and late syphilis with clinical manifestations other than neurosyphilis.

The denominator population for Congenital Syphilis is the total number of live births in the given year(s). See Population Data Sources for more information.

Congenital syphilis reporting may be delayed as a result of case investigation and validation. Cases for previous years are added to CDC's surveillance databases throughout the year. Congenital syphilis data reported after publication of the current annual STD surveillance report will appear in subsequent reports and are assigned by the case patient's year of birth.

Gender is shown as "unknown" for persons diagnosed with congenital syphilis, because the baby's gender is not collected as part of case surveillance data.
