Mapping Ohio’s 35,984 coronavirus cases, updates and trends

COLUMBUS, Ohio – Ohio’s 2,206 known coronavirus-related deaths are spread across 69 of the state’s 88 counties, with total cases now reaching 35,984, the Ohio Department of Health reported Monday.

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

The death total increased 11% in the last week from 1,987, while the case total was up 10.8% from 32,477.

At the same time one week ago, deaths were up 19.9% over seven days, and cases were up 14.1%.

The number of deaths reported daily for the last week were 51, 6, 18, 33, 54, 42 and 15. The reports lag several days from the actual date of death and sometimes are reported by the state in clusters

Separately, data from the Ohio Hospital Association said there were 761 coronavirus patients in reporting hospitals across the state, including 324 in intensive care units. These numbers have trended down for weeks, though the latest ICU count is up slightly from the previous day. On April 20, there were 1,087 COVID-19 patients, with 520 in ICU.

One-in-325 Ohioans now are reported to have been infected with coronavirus.

The state’s case total has gone up daily by 471, 479, 468, 651, 476, 433 and 529 over the last week.

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%.

The case total includes 5,736 state prison inmates or staff. The prison department on Sunday reported 5,736 cases to date (4,556 inmates and 1,180 staff), 81% of whom have recovered. Seventy-five prisoners and four staff have died.

The state health department last updated the number of deaths for nursing home patients on Wednesday, May 27, with a total of 1,247, representing 70% of all known COVID-19 deaths in Ohio at that point.

A total of 398,066 tests have been conducted, up 67,732 in the last week. One week earlier, there were 60,637 tests.

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, 5,124 have had an onset in the last two weeks. More than five times as many – 28,564 – are older.

The state is now reporting that the onset of symptoms was as early as January for 16 cases, up from 13 on Friday – four from Montgomery County, three from Warren, two from Miami and one each from Lake, Mahoning, Medina, Richland, Summit, Union and Wood.

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

More than three-fourths the deaths have been to people age 70 and up, with 543 (24.6%) in their 70s and 1,174 (53.2%) at least 80 years old. Those 80 and up accounted for 44% of deaths from all causes nationally in 2017.

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

The counties with the most deaths are Franklin (271), Lucas (248), Cuyahoga (241), Mahoning (178), Summit (176) and Hamilton (151).

For the deaths in which race was reported, 80.1% are white, and 17.2% are black. Yet for total cases, 56.5% are white and 27.6% black. Ohio’s population is 81.9% white and 13% black, census estimates say.

Among all cases reported to date, 6,112 have been hospitalized, including 1,569. A week earlier, these totals were 5,511 and 1,443.

The counties with the most cases are Franklin (5,933), Cuyahoga (4,508), Hamilton (2,698) Marion (2,668). Franklin (Columbus), Cuyahoga (Cleveland) and Hamilton (Cincinnati) are Ohio’s most populated counties. Marion’s cases have mostly been in prisons.

The first three cases were confirmed on March 9. The total topped 100 on March 19, exceeded 1,000 on March 27 and then 10,000 on April 18.

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 2,483 “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.
