COVID-19 Data Resources


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 with data hosted on, Connecticut's open data portal. Questions or suggestions can be posted via individual datasets or here.

Connecticut Case Overview

The Connecticut Department of Public Health (DPH) provides regular updates on confirmed and probable 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.
The map below shows the average daily rate of new cases of COVID-19 by town during the past two weeks. Only cases among persons living in community settings are included in this map; the map does not include cases among people who reside in nursing home, assisted living, or correctional facilities.
Hospitalization data are 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 datasets below provide statewide, county and town data, and additional disaggregations:
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.  A report on COVID-19 race and ethnicity data at the state level and in the ten largest towns can be downloaded here
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. 

Economic Impact

Administrative data have some indicators of the economic impact of COVID-19.
Data on unemployment claims in Connecticut can be found on the Department of Labor's website. Data on daily and weekly applications to the Department of Social Services before and during the COVID-19 pandemic are updated weekly. Data on distribution of PPP Loans to Connecticut Businesses from the Small Business Administration are posted as they are updated. Other measures of economic impact and recovery can be accessed via the Opportunity Insights Economic Tracker.

Congregate Settings

A congregate setting is an environment where a group of people reside, meet, or gather in close proximity for either a limited or extended period of time. Examples include long-term care facilities, schools, and prisons. Some Connecticut state agencies are publishing data on COVID-19 and congregate settings, including: 

School Learning Model Indicators

The Connecticut Department of Health (DPH) and the Department of Education (CSDE) have identified four indicators to support local school district decision-making on the level of in-person, hybrid (blended), and remote learning model for Pre K-12 education. The four indicators are summarized by county in the table below. 
More detail about the school learning model indicators can be found on the CT School Learning Model Indicators page. The dataset CT School Learning Model Indicators by County (14-day metrics) summarizes the indicators by county.

Data library

Connecticut state agencies are working together to compile data to help understand the COVID-19 pandemic. A current listing of datasets that may be of interest are linked below: 
COVID-19 Testing, Cases, Hospitalizations, and Deaths
  1. Coronavirus Disease 2019 (COVID-19)-Associated Hospitalization Surveillance Network (COVID-NET): COVID-NET provides a weekly summary of hospitalization data from counties in the 10 Emerging Infections Program (EIP) and states in the Influenza Surveillance Project. Demographic and clinical data includes race/ethnicity, sex, selected underlying medical conditions, and hospitalizations by age, as well as weekly and cumulative rates. Connecticut participates in the EIP, which includes only New Haven and Middlesex counties. All data are preliminary and are subject to change as updated data is reported.
