COLUMBUS, Ohio - The 11,602 coronavirus cases are spread across 87 of Ohio’s 88 counties, with 471 deaths, the Ohio Department of Health reported Sunday.

This map is updated daily: see this link for the latest Ohio coronavirus maps.

The total was up from 10,222 cases in the same 87 counties on Friday, while the number of deaths increased from 451. Sparsely populated Vinton County has no known cases.

The number of coronavirus-related deaths reported by state officials have ranged from 16 to 28 a day over the last couple of weeks. Some deaths may be added later for the most recent days as more information becomes available.Rich Exner, cleveland.com

The 1,380 newly reported cases marked the sharpest increase reported in a single day. Officials attribute the increases to additional testing in state prisons, including testing people without symptoms, many of whom have then found to be positive.

Earlier this weekend, the prison department reported coronavirus cases for 1,441 inmates and 218 staff on Saturday across Ohio. This was up from 692 inmates and 197 staff on Friday, and 489 inmates and 184 staff on Thursday. Saturday’s total included 1,057 inmates and 103 staff at the Marion Correctional Institution.

Marion County alone accounted for more than half of the state’s increase in cases on Saturday. Reported cases countywide grew from 110 on Tuesday to 1,834 on Sunday.

Despite a 14% increase in cases reported statewide on Sunday, other benchmarks grew more slowly – 4% for known deaths, 6% for hospitalizations, and less than 1% for hospital admissions in intensive care.

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 310 additional “probable” cases than would have been reported previously, including 27 on Sunday.

However, Dr. Amy Acton, the state’s health director, said the reported numbers still significantly understate how many people likely have been infected. With what Acton has said is rationing of testing supplies nationally, Ohio has concentrated on the sickest people, prisons and health care workers.

Before this weekend, the daily increase had been in the 4% to 8% range since April 7. This had been much lower than in March when the daily increases were often above 20% and sometimes above 40%.

These are the estimated onset dates since March 1 for each of Ohio's reported coronavirus case. Confirmation often is days after the first symptoms, leading to smaller numbers for the most recent days. Not included in this chart are 29 cases with February onsets. The recent spike could be related in increasing testing in prisons, where state officials says several cases were found with people who had no previous symptoms.Rich Exner, cleveland.com

The state 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, 5,528 have had an onset in the last two weeks. Most of the cases – 5,603 – 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 age range for confirmed cases to date is from under 1 to 106, with a median age of 52.

Nearly half of all deaths (49.5%) have been to people age 80 and over, though this age group accounts for only 4% of Ohio’s total population, according to census estimates. About half of Ohioans are under 40, yet only three people this age are known to have died from coronavirus, all in their 30s.

The deaths include cases in 49 counties, including highs of 53 in Cuyahoga County, 48 in Mahoning, and 33 each in Lucas and Hamilton.

Among the 418 deaths in which race was reported, 78.2% are white, 16.3%. Ohio’s population is 81.9% white and 13% black, census estimates say.

Acton said Thursday about 1,000 remain in the hospital across Ohio with coronavirus. The state did not provide updates to this particular statistic over the weekend.

Among all cases reported to date, 2,565 were hospitalized, and 765 spent at least some time in intensive care units. These totals were 2,519 and 760 Saturday, 2,424 and 740 Friday, 2,331 and 707 Thursday, and 2,237 and 677 Wednesday.

The counties with the most cases are Marion, with 1,834 cases mostly from the prison, and Ohio’s largest, Franklin (Columbus) with 1,513 and Cuyahoga (Cleveland) with 1,466. Vinton County, with a population of just 13,085, has no cases.

The statewide total of confirmed cases was 6,604 a week ago; the third day the expanded reporting criteria were used.

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.

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.

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