COLUMBUS, Ohio - The 3,739 confirmed coronavirus cases to date in Ohio are spread across 76 of the state’s 88 counties, with 102 deaths, the Ohio Department of Health reported Saturday.

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

The total was up from 3,312 cases in 75 counties from Friday, while the number of deaths increased from 91. Saturday’s report included the first case for Adams County in southwest Ohio.

Details for each county including hospitalizations, deaths and per capita rates are in a chart at the bottom of this story.

The increase in newly reported cases was up 13%. This continues a general trend of easing over the last several days. Total cases increased 14%, 14%, 16%, 14%, 17%, 18%, 24% and 31% the previous days.

These are the estimated onset dates for each of Ohio's 3,739 confirmed coronavirus cases. Note, however, that confirmation often is days after the first symptoms, leading to smaller numbers for recent dates.Rich Exner, cleveland.com

However, Ohio Health Director Dr. Amy Acton has repeatedly cautioned that the totals are understated, often calling them the “tip of the iceberg," because of limited testing.

Acton said testing is planned for a sample population to get a better understanding of the spread of the virus in Ohio. Currently, there has been a focus on testing healthcare workers and those with severe problems, with 38,375 tests completed so far.

The state has not released any information on the number of current cases, excluding those who no longer have coronavirus, saying that information is not yet available but efforts will be made to track it.

Health officials have said coronavirus often runs its course in 14 days, though severe cases can last longer. Based on state estimates of the onset of symptoms, 2,188 of the cases confirmed to date had an onset in the last two weeks, excluding people who have died.

Seventy-three percent of the known coronavirus deaths in Ohio have been age 70 and older.Rich Exner, cleveland.com

The age range to date is from under 1 to 101, with a median age of 54; 20% are health care workers.

There are now 32 confirmed cases per 100,000 people in Ohio, with the highest rates in Mahoning County (109.3 cases per 100,000), Miami (64.5), Lucas (63.5) and Cuyahoga (63.2).

The state reported 1,006 hospitalizations to date, with 326 in intensive care units. This is up from 895 and 288 on Friday, 802 and 260 on Thursday and 679 and 222.

The statewide total of confirmed cases was 2,902 on Thursday, 2,547 on Wednesday, 2,199 on Tuesday, 1,933 on Monday, 1,653 on Sunday, 1,406 on Saturday, and 1,137 last Friday.

The first three cases were confirmed on March 9. The total topped 100 on March 19, exceeded 1,000 on March 27, topped the 2,000 on Tuesday and then moved over 3,000 on Friday.

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. On Saturday, the state reported just one more case for Cuyahoga County on Saturday (781) than on Friday (780).

The chart below shows what the Ohio Department of Health reported on Thursday. Cleveland.com calculated the cases per 100,000 rates based on 2019 census population estimates.
