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 Monday morning, there have been at least 86,799 cases and 1,422 deaths in Delaware 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 unique individuals reported tested with a P.C.R. viral diagnostic test 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 Delaware »

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
+ Prisons and jails 1,982 cases at 5 prisons
+ Nursing homes 1,183 cases at 17 facilities
+ Colleges and universities 1,160 cases at 6 schools

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 Delaware, the Times primarily relies on reports from the state. Delaware typically releases new data each day. Weekend counts may be lower because fewer sources report to the state. 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:

June 23: Delaware added 67 deaths from earlier in the year after reconciling death certificate records.

July 24: Delaware added 49 deaths from earlier in the year after reconciling death certificate records.

July 25: Delaware removed duplicate cases.

Sept. 21: Delaware added six deaths identified from death certificates that occurred between April and August.

Dec. 19: Delaware announced that a reporting delay on Dec. 18 resulted in a higher total on Dec. 19.

Feb. 5: Delaware added 54 deaths from December and January after reviewing records.

Feb. 7: Delaware added 260 cases from recent days after resolving a technical issue.

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.
