The latest in COVID-19 data and surveillance.
- Report COVID-19 cases. CDC has developed a form that provides a standardized approach to reporting COVID-19 cases (individuals with at least one respiratory specimen that tested positive for the virus that causes COVID-19). These data are needed to track the impact of the outbreak and inform public health response.
- Monitoring COVID-19 cases. COVID-19 surveillance draws from a combination of data sources from existing influenza and viral respiratory disease surveillance, syndromic surveillance, case reporting, commercial lab reporting, ongoing research platforms, and other new systems designed to answer specific questions. These systems combined create an updated, accurate picture of SARS-COV-2 spread and its effects in the United States and provide data used to inform the U.S. national public health response to COVID-19.

For surveillance of COVID-19 and its cause, SARS-CoV-2, in the United States, CDC is using multiple surveillance systems run in collaboration with state, local and territorial health departments, public health, commercial and clinical laboratories, vital statistics offices, health care providers, emergency departments and academic partners to monitor COVID-19 disease in the United States.
- COVIDView Weekly Summary. This CDC report provides a weekly summary and interpretation of key indicators that have been adapted to track the COVID-19 pandemic in the United States.
- Cases in U.S. This page is updated daily. Numbers close out at 4 p.m. the day before reporting.
- Hospitalization Rates. CDC monitors lab-confirmed COVID-19 hospitalizations, risk factors, and outcomes of those hospitalized each week.
- Mortality Reporting. CDC provides provisional death counts for COVID-19 and pneumonia based on death certificates with updates Monday-Friday.
- Information for Reporting Cases. To prevent further spread of SARS-CoV-2 and to collect information to better understand the virus and its impact on health outcomes, CDC has developed a form that provides a standardized approach to reporting COVID-19 cases (individuals with at least one respiratory specimen that tested positive for the virus that causes COVID-19).
- COVID-NET Interactive: Interactive and downloadable data used to estimate age-specific hospitalization rates on a weekly basis and describe characteristics of persons hospitalized with COVID-19.
- CDC COVID-19 Information Management Resources (VADS). CDC develops and maintains the COVID-19 data interoperability standards and regulations repository that is based on communication and collaboration with standard development and standard implementation organizations.
National COVID-19 reporting: CDC works with state and territorial public health partners to coordinate COVID-19 case reporting nationally.
- The COVID-19 case definition is standardized with the Council of State and Territorial Epidemiologists (CSTE), which issued on April 5, 2020 an interim COVID-19 position statementpdf iconexternal icon that includes a case definition and made COVID-19 a nationally notifiable disease.
- Information for Reporting Cases. To better understand the virus and its impact on health outcomes, CDC has developed a form that provides a standardized approach to reporting COVID-19 cases (individuals with at least one respiratory specimen that tested positive for the virus that causes COVID-19).
- National Notifiable Diseases Surveillance System (NNDSS) for case-based surveillance (which includes mechanisms to securely receive case data and share with CDC partners and technical assistance with onboarding new HL7 message mapping guides)
- National Syndromic Surveillance Program (NSSP) (including Emergency Department visits for onboarded facilities and COVID-19 test orders and results for 6 major commercial laboratories)

- Electronic Surveillance System for the Early Notification of Community-based Epidemics (ESSENCE) for quality-controlled line-level data for ED visits and 6 major commercial labs testing for COVID-19—including PCR and as of now IgA, IgG, and IgM as well; ESSENCE also provides advanced tools to rapidly query, visualize and analyze these data).
