Sexually Transmitted Disease Morbidity
|
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:

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: |
|
'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:
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.
- See How do I organize my data? for more information.
- Also see "How do I select items from the list box?" for help using the screen.
Hints:
-
About charts:
You cannot make charts when your data has more than two By-Variables. -
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. -
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. - When data is grouped by Region (when Region is selected as a By-Variable) then the data includes US and outlying areas.
-
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.
- 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.

Notes:
- Syphilis is classified in groups. The category Primary and Secondary Syphilis includes incidence of disease originally reported under the two individual disease categories primary syphilis and secondary syphilis. The category Primary, secondary and early latent syphilis includes incidence of disease originally reported under the three individual disease categories primary syphilis, secondary syphilis, and early latent syphilis.
- Each state is a unique jurisdiction with different reporting rules for each disease. Reporting rules vary each year. See Reporting Issues for more information.
- Select "all diseases" or any single disease category to get rates. Rates are not calculated when disease categories are combined, because the reporting populations differ by disease.
- When the data are exported, separate columns show both the label and the code for each value. To see the full list of labels and code values, request data grouped by disease for "All Diseases" and export the data results.

Morbidity Rates: |
The following issues affect the calculation of morbidity rates:
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: 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
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.(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 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. |
