This data portal provides centralized access to data on the COVID-19 emergency and response, and supplements information available on the state's COVID-19 portal. All data are also hosted on data.ct.gov, Connecticut's open data portal. Questions or suggestions can be posted via individual datasets or here.

The Connecticut Department of Public Health (DPH) provides daily updates on confirmed cases of COVID-19, hospitalizations and deaths. All data in the daily reports are preliminary and data for previous dates may be updated as new reports are received and data errors are corrected. Data include patients tested at the State Public Health Laboratory, hospital, and commercial laboratories.

Hospitalization data were collected by the Connecticut Hospital Association. Deaths reported to either the Officer of the Chief Medical Examiner (OCME) or DPH are included in the daily COVID-19 update. For public health surveillance, laboratory-confirmed COVID-19-associated deaths are defined as patients who tested positive for COVID-19 around the time of death; this is not a determination of the cause of death.

The charts and tables below provide the statewide data, and additional aggregations by town and county. Testing data sets include:

Additional documentation on the data sources and methods are available via daily updates from DPH; a repository of daily update reports is posted here. Rate calculations are based on population estimates from DPH. 

Analysis of COVID-19 cases and associated deaths by race and ethnicity is released in the DPH daily reports, as well as in a report on COVID-19 race and ethnicity data at the state level and in the ten largest towns, which can be downloaded here. 

National COVID-19 statistics and information about preventing spread of COVID-19 are available from the Centers for Disease Control and Prevention. A weekly report on seasonal influenza activity can be found on the DPH website. 

Additional dashboards and data visualizations are available through: Department of Public Health, Connecticut Data Collaborative, DataHaven, University of Connecticut Department of Geography, FEMA Region 1 and the Connecticut Conference of Municipalities.

Data are reported separately by town, county and for the state. Totals from town and county-level data may not reconcile with state totals due to records that are pending address validation. 

In the future, we plan to post data on what the state is doing to respond to the emergency, including data on support for small businesses, employment and job training programs, consumer protection efforts and distribution of resources such as PPE (personal protective equipment), food and books and laptops for students. 

Connecticut state agencies are working together to compile data to help understand the COVID-19 pandemic. Datasets that may be of interest are linked below:
