COLUMBUS, Ohio - The 15,963 coronavirus cases to date in Ohio are spread across 87 of the state’s 88 counties, with 728 deaths, the Ohio Department of Health reported Sunday.

Small increases were reported for key benchmarks, with cases up 2.4% over what was reported Saturday. Deaths were up 2.4%, and the number of admissions to hospitals to date was up 2%, including a 1.5% increase for patients in intensive care units.

Separately, the Ohio Hospital Association said there were 1,067 current coronavirus patients on Friday from reporting hospitals across the state, continuing a steady trend. The total has been in the 1,029 to 1,122 range since April 14.

The daily increase in new cases reported Sunday by the Ohio Department of Health was the smallest since April 14, and the lowest percentage changes since the state began reporting cases in early March.Rich Exner, cleveland.com

The total number of cases to date was up 376 from 15,587 in the same 87 counties on Saturday, while the number of deaths increased from 711. Tiny Vinton County has no known cases.

Sunday marked the smallest increase in cases since April 14. Higher increases last weekend were tied heavily to stepped-up testing in prisons, even among inmates without symptoms.

The prison department on Saturday reported 4,221 cases (3,845 inmates and 376 staff). This was up from 489 inmates and 184 staff April 16. The total included 2,197 at the Marion Correctional Institution, and 1,644 at the Pickaway Correctional Institution.

Also impacting comparisons to earlier trends, 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 603 “probable” cases in the total over what would have been previously reported.

Dr. Amy Acton, the state’s health director, has said Ohio has largely plateaued overall. Acton said many more people likely have been infected than the numbers show.

Gov. Mike DeWine on Friday announced that Ohio will significantly increase testing capacity. While more testing is viewed as a key to containing the spread of the virus, it will also cause the number of reported cases to go up.

A total of 115,783 tests have been conducted.

Sunday marked the fifth consecutive day of case increases of 4% or below. In March the daily increases were often above 20%, and sometimes above 40%.

Ohio unlike some other states has not released information on the number of current cases remaining, excluding those who no longer have coronavirus, saying that information is not available.

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.

Among the cases reported to date, excluding those who have died, 7,431 have had an onset in the last two weeks. A larger share of the cases – 7,804 – are older.

The age range for confirmed cases to date is from under 1 to 106, with a median age of 51.

Nearly half of all deaths (349 of 728, or 47.9%) have been to people age 80 and over. This age group accounted for 44% of the deaths nationally in 2017.

About half of Ohioans are under 40, yet only four people is this age are known to have died from coronavirus, all in their 30s.

The deaths are spread across 58 counties, including highs of 91 in Cuyahoga County, 66 in Mahoning, 59 in Lucas, 56 in Hamilton and 53 in Franklin County.

Among the 659 deaths in which race was reported, 78.9% were white, and 16.5% were black. Ohio’s population is 81.9% white and 13% black, census estimates say.

These are the hospital admission dates in April listed by the Ohio Department of Health for known coronavirus cases. Dates are not available for about 10% of the admissions.Rich Exner, cleveland.com

Among all cases reported to date, 3,178 have been hospitalized, including 952 in intensive care units. These totals were 3,115 and 938 on Saturday, 3,053 and 920 on Friday, and 2,960 and 900 Thursday.

The counties with the most cases are Marion (2,178), Franklin (1,942), Cuyahoga (1,902), and Pickaway (1,658). Franklin (Columbus) and Cuyahoga (Cleveland) are Ohio’s two most populated counties; Marion and Pickaway have high numbers of prisoners with COVID-19.

Vinton County, with a population of just 13,085, has no cases.

Here is how the known number of Ohio coronavirus cases has grown from three on March 9 to 15,963 on Sunday, April 26.Rich Exner, cleveland.com

The statewide total of confirmed cases was 11,602 a week ago.

The first three cases were confirmed on March 9. The total topped 100 on March 19, exceeded 1,000 for the first time on March 27, and went over 10,000 on Saturday, April 18.

Some numbers may change from day to day. As the state works to clean data, it sometimes 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 data from the Ohio Department of Health. Cleveland.com calculated the cases per 100,000 rates based on 2019 census population estimates.
