About this data For total cases and deaths: The map shows the known locations of coronavirus cases by county. Circles are sized by the number of people there who have tested positive or have a probable case of the virus, which may differ from where they contracted the illness. For hot spots: The hot spots map shows the share of population with a new reported case over the last week.

As of Thursday morning, there have been at least 278,184 cases and 7,595 deaths in Connecticut since the beginning of the pandemic, according to a New York Times database.

To Our Subscribers

The public, medical researchers, and government agencies continue to rely on our comprehensive tracking of the pandemic. Thank you for helping us uncover the facts.

Learn more about this project.

The New York Times is engaged in a comprehensive effort to track details about every reported case in the United States, collecting information from federal, state and local officials around the clock. The numbers in this article are being updated several times a day based on the latest information our journalists are gathering from around the country.

The New York Times has found that official tallies in the United States and in more than a dozen other countries have undercounted deaths during the coronavirus outbreak because of limited testing availability.

These are days with a reporting anomaly. Read more here. Note: The seven-day average is the average of a day and the previous six days of data.

Daily case and death reports show the severity of the pandemic over time. The picture can be put into further context by considering the number of tests performed and people hospitalized.

Covid patients in hospitals that day
7-day average
Source: Testing and hospitalization data from the Covid Tracking Project.
About this data Currently hospitalized is the number of patients with Covid-19 reported by the state to be in a hospital on that day. Dips and spikes could be due to inconsistent reporting by hospitals. Tests represent the number of individual P.C.R. viral test specimens reported tested that day.

If the previous level of testing was low, and hospitalizations are not increasing, a rise in daily cases could be explained as a result of increased testing. If daily tests have been increased and cases and hospitalizations have fallen or stayed low, that is a sign that the situation is improving or under control. Hospitalizations and deaths usually lag behind new cases, as it takes time for symptoms to develop and worsen.

Because the definitions used for testing and hospitalization data vary between states, it is not always possible to compare that data in one state to the figures reported in another.

We’re tracking restrictions in Connecticut »

Since March, The Times has paid special attention to cases in nursing homes, food processing plants, correctional facilities and now at colleges and universities. Information on cases linked to these places comes from official releases by governments, companies and institutions directly. The Times is publishing lists of groupings of 50 or more cases related to a specific site, workplace, school or event.

Cases connected to Cases Location
+ Nursing homes 13,570 cases at 144 facilities
+ Colleges and universities 4,757 cases at 20 schools
+ Prisons and jails 4,588 cases at 15 prisons

The counts in this table of coronavirus cases at individual nursing homes were last updated as recently as Jan. 12, 2021. Since then, we have continued to update state-level totals for cases and deaths in long-term care facilities.

About the data

In data for Connecticut, the Times primarily relies on reports from the state. Connecticut typically releases new data on weekdays. Counts on Mondays or Tuesdays may include totals from the weekend. The state reports cases and deaths based on a person’s permanent or usual residence.

The Times has identified the following reporting anomalies or methodology changes in the data:

May 27: Connecticut announced that they were removing 356 positive cases, which were determined to be duplicates, from their total case count.

June 18: Connecticut removed previously reported cases.

July 24: Connecticut included about 400 cases from a testing backlog.

July 29: Connecticut included a backlog of about 400 cases from April through June.

Nov. 5: Connecticut added a backlog of 530 cases identified through antigen testing from August through November.

Dec. 28: Connecticut reported data for multiple days following the Christmas holiday.

In July, the state stopped reporting new data on weekends.

The tallies on this page include probable and confirmed cases and deaths.

Confirmed cases and deaths, which are widely considered to be an undercount of the true toll, are counts of individuals whose coronavirus infections were confirmed by a molecular laboratory test. Probable cases and deaths count individuals who meet criteria for other types of testing, symptoms and exposure, as developed by national and local governments.

Governments often revise data or report a single-day large increase in cases or deaths from unspecified days without historical revisions, which can cause an irregular pattern in the daily reported figures. The Times is excluding these anomalies from seven-day averages when possible.
