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.

Cases Connected To Location Cases
Ohio State University Columbus, Ohio 8,173
Miami University (Ohio) Oxford, Ohio 3,419
University of Cincinnati Cincinnati, Ohio 3,288

About this data 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 or event.

About the data

In data for Ohio, The Times primarily relies on reports from the state. The state updates death counts a few times each week. Prior to March 2021, it released new data daily. 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:

  • April 27, 2021: The reported number of tests likely includes many older tests.
  • April 7, 2021: The reported number of tests likely includes many older tests.
  • March 5, 2021 to March 8, 2021: Ohio added more than 400 deaths of residents who died out of state.
  • March 2, 2021: Ohio changed its methodology for reporting coronavirus deaths to use death certificates, resulting in a one-time decrease.
  • Feb. 13, 2021: Ohio added about 1,125 deaths from recent months.
  • Feb. 12, 2021: Ohio added about 2,500 deaths from recent months.
  • Feb. 11, 2021: Ohio added about 650 deaths from recent months.
  • Jan. 2, 2021: Ohio reported data for two days after reporting no data on New Year's Day.
  • Dec. 26, 2020: Ohio reported data for Dec. 25 and 26 after reporting no data on Christmas.
  • Dec. 8, 2020: Ohio announced a backlog of cases identified through antigen testing.
  • Nov. 27, 2020: Ohio reported data for Nov. 26 and Nov. 27 after reporting no data on Thanksgiving.
  • Sept. 15, 2020: Ohio added many deaths that occurred weeks earlier.

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.
