About this data Sources: State and local health agencies (cases, deaths); U.S. Department of Health and Human Services (tests, hospitalizations). The seven-day average is the average of a day and the previous six days of data. Currently hospitalized is the most recent number of patients with Covid-19 reported by hospitals in the state for the four days prior. Dips and spikes could be due to inconsistent reporting by hospitals. Hospitalization numbers early in the pandemic are undercounts due to incomplete reporting by hospitals to the federal government. Tests represent the number of individual P.C.R. viral test specimens tested by laboratories and state health departments and reported to the federal government.

Outbreak clusters

Since March 2020, The Times has paid special attention to cases in the types of places with some of the worst outbreaks, like nursing homes, food processing plants and correctional 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:

  • March 11, 2021: Delaware announced a backlog of cases after a testing provider resolved a technical issue.
  • Feb. 7, 2021: Delaware added 260 cases from recent days after resolving a technical issue.
  • Feb. 5, 2021: Delaware added 54 deaths from December and January after reviewing records.
  • Dec. 19, 2020: Delaware announced that a reporting delay on Dec. 18 resulted in a higher total on Dec. 19.
  • Sept. 21, 2020: Delaware added six deaths that occurred between April and August following a review of death certificate records.
  • July 25, 2020: Delaware removed a number of duplicate cases.
  • July 24, 2020: Delaware added 49 deaths from earlier in the year after reconciling death certificate records.
  • June 23, 2020: Delaware added 67 deaths from earlier in the year after reconciling death certificate records.

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.
