Currently, CDC provides the public with COVID-19 case surveillance data in two ways: an 11 data element public use dataset of the line-listed dataset of all COVID-19 cases shared with CDC and a 31 data element restricted access dataset of the line-listed dataset of all COVID-19 cases shared with CDC.

The following are true for both the public use dataset and the restricted access dataset:

- Data elements can be found on the COVID-19 case report form located at www.cdc.gov/coronavirus/2019-ncov/downloads/pui-form.pdf.

- Data are considered provisional by CDC and are subject to change until the data are reconciled and verified with the state and territorial data providers.

- Data are suppressed to protect individual privacy.

- The datasets include all cases with an initial report date of case to CDC at least 14 days prior to the creation of the previously updated datasets. This 14-day lag will allow case reporting to be stabilized and ensure that time-dependent outcome data are accurately captured.

- Datasets are updated monthly.

- Both datasets are created using CDC’s operational Policy on Public Health Research and Nonresearch Data Management and Access and include protections designed to protect individual privacy.

Overview

The COVID-19 case surveillance system database includes individual-level data reported to U.S. states and autonomous reporting entities, including New York City and the District of Columbia (D.C.), as well as U.S. territories and states. On April 5, 2020, COVID-19 was added to the Nationally Notifiable Condition List and classified as “immediately notifiable, urgent (within 24 hours)” by a Council of State and Territorial Epidemiologists (CSTE) Interim Position Statement (Interim-20-ID-01). CSTE updated the position statement on August 5, 2020 to clarify the interpretation of antigen detection tests and serologic test results within the case classification. The statement also recommended that all states and territories enact laws to make COVID-19 reportable in their jurisdiction, and that jurisdictions conducting surveillance should submit case notifications to CDC. COVID-19 case surveillance data are collected by jurisdictions and shared voluntarily with CDC.

The deidentified data in the public use dataset include demographic characteristics, exposure history, disease severity indicators and outcomes, clinical data, laboratory diagnostic test results, and comorbidities. All data elements can be found on the COVID-19 case report form located at www.cdc.gov/coronavirus/2019-ncov/downloads/pui-form.pdf.

The Case Surveillance Task Force and Surveillance Review and Response Group (SRRG) within CDC’s COVID-19 Response provide stewardship for datasets that support the public’s access to COVID-19 data while protecting individual privacy.

COVID-19 Case Reports

COVID-19 case reports have been routinely submitted using standardized case reporting forms. On April 5, 2020, CSTE released an Interim Position Statement with national surveillance case definitions for COVID-19 included. Current versions of

A COVID-19 case surveillance restricted access dataset with 31 elements, including state and county of residence information, is available to the public. To access this dataset, complete the Registration Information and Data Use Restrictions Agreement (RIDURA). Other important information is provided below.

Requesting Access

Please review the following documents to determine your interest in accessing the COVID-19 Case Surveillance Restricted Access Detailed Data file:

1) CDC COVID-19 Case Surveillance Restricted Access Detailed Data: Summary, Guidance, and Limitations Information and Restricted Access Data Use Agreement Information

2) Data Dictionary for the COVID-19 Case Surveillance Restricted Access Detailed Data

The next step is to complete the RIDURA. Once complete, CDC will review your agreement. Once access is granted, ASK SRRG (eocevent394@cdc.gov) will email you information about how to access the data through GitHub. If you have questions about obtaining access, email eocevent394@cdc.gov.
