This map and data is updated frequently: see this link for the latest Ohio coronavirus maps.

The death total increased 1.6% from 2,098 the day before, while the case total was up 1.9% from 33,915.

Separately, data from the Ohio Hospital Association said there were 833 coronavirus patients in reporting hospitals across the state, including 326 in intensive care units. Though the latest numbers may be revised when more information becomes available, they have been trending down. On April 20, for example, there were 1,087 COVID-19 patients, with 520 in ICU.

Cases have now been reported for 1-in-338 Ohioans.

COVID-19 hospital stays have been trending down in Ohio. This chart shows the number of patients on a given day, as reported by hospitals to the Ohio Hospital Association. Out-of-state patients are included. Totals for the most recent day or two may be revised later.Rich Exner, cleveland.com

The number of deaths reported daily for the last week were 33, 54, 42, 15, 18, 13 and 84. The reports lag several days from the actual date of death and sometimes are reported by the state in clusters

The state’s case total has gone up daily by 651, 476, 433, 529, 566, 503 and 614 over the last week.

Higher increases in mid-April were tied heavily to stepped-up testing in pri

ons, even among inmates without symptoms. The prison department on later Friday reported 5,714 cases to date (4,541 inmates and 1,173 staff), 81% of whom have recovered.

The daily increase in total cases has been under 4.2% since April 22 and under 2.6% since May 12. In March the daily increases were often above 20%, and sometimes above 40%.

A total of 367,526 tests have been conducted, up 9,804 from Thursday. The previous three Fridays, 8,679, 12,782 and 8,209 new tests were reported.

These are the number of cases based on the estimated onset dates since April 18 for Ohio's reported coronavirus cases. Confirmation often is days after the first symptoms, leading to smaller numbers for the most recent days.Rich Exner, cleveland.com

Ohio unlike some other states does not provide information on the number of current cases remaining, excluding those who no longer have coronavirus, saying that information is not available. This information is provided only by the prison department, and by the health department for nursing homes.

Yet health officials have said coronavirus often runs its course in 14 days, longer for the most severe cases, indicating that many known cases no longer exist. Most of the known cases are older.

Among the cases reported to date, excluding those who have died, 5,194 have had an onset in the last two weeks. More than five times as many – 27,241 – are older.

Health officials say coronavirus often lasts less than two weeks, though it can be longer for severe cases. This graphic provides a breakdown of the cases reported to date – based on onset before and after two weeks ago.Rich Exner, cleveland.com

The state is now reporting that the onset of symptoms was as early as January for 13 cases – three from Warren County, three from Montgomery, two from Miami, and one each from Lake, Richland, Summit, Union and Wood counties.

The age range for confirmed cases to date is from under 1 to 109, with a median age of 49. The median age for deaths is 81.

Coronavirus by age in Ohio

Most Ohio coronavirus deaths have been to people age 80 and up, but cases resulting in hospitalization are more spread out among age groups.Rich Exner, cleveland.com

Three quarters of the deaths have been to people age 70 and up, with 523 (24.5%) in their 70s and 1,134 (53.2%) at least 80 years old. Those 80 and up accounted for 44% of deaths from all causes nationally in 2017.

Six people in their 20s have died and another 15 in their 30s.

The state health department last updated the number of deaths for nursing home patients on Wednesday, with a total of 1,247, representing 70% of all known COVID-19 deaths in Ohio at that point.

The counties with the most deaths are Franklin (256), Lucas (240), Cuyahoga (226), Mahoning (173), Summit (172) and Hamilton (147).

Death rates by age for COVID-19 in Ohio

Based on reported coronavirus cases by the Ohio Department of Health, 30.6% of people age 80 and up contracting the virus have died, 17.1% in their 70s have died, and 6.5% in their 60s.Rich Exner, cleveland.com

For the deaths in which race was reported, 80% are white, and 17.4% are black. Yet for total cases, 57% are white and 27.9% black. Ohio’s population is 81.9% white and 13% black, census estimates say.

Among all cases reported to date, 5,947 have been hospitalized, including 1,533 in intensive care units. These totals were 5,811 and 1,516 on Thursdays, 5,700 and 1,516 on Wednesday, and 5,579 and 1,450 on Tuesday, 5,511.

The counties with the most cases are Franklin (5,674), Cuyahoga (4,318), Marion (2,657). Franklin (Columbus) and Cuyahoga (Cleveland) are Ohio’s most populated counties. Marion’s cases have mostly been in prisons.

The statewide total of cases was 30,794 a week ago, and 17,303 a month ago on April 29.

The first three cases were confirmed on March 9. The total topped 100 on March 19 and exceeded 1,000 on March 27.

The state on April 10 began new reporting standards to include more types of testing and cases identified from non-testing evidence. This has resulted in 2,364 “probable” cases being included in the total cases reported for Ohio to date.

Corrections in the data are made from day to day by the state. Sometimes the state has reduced the number of cases in individual counties from one day to the next as corrected residency information is received.

The chart below is based on the most recent case data from the Ohio Department of Health. Cleveland.com calculated the cases per 100,000 rates based on 2019 census population estimates.
