COLUMBUS, Ohio (WJW) — Governor Mike DeWine and the Ohio Department of Health released a new map for the Ohio Public Health Advisory Alert System, which determines a county’s risk for coronavirus.

As of Thursday, twelve Ohio counties, including Cuyahoga and Erie, are considered a Level 3 emergency, which means there’s very high exposure and spread of COVID-19.

The alert rankings are based on the following factors: new cases per capita, sustained increase in new cases, proportion of cases that are not in congregate settings, sustained increase in COVID-19-related emergency room visits, sustained increase in COVID-19-related outpatient visits including telehealth, sustained increase in COVID-19 hospital admissions and intensive care unit occupancy.

Counties in Level 3, or the Red Level, meet four or five of the aforementioned indicators.

Last week Ohio had eleven counties under a Level 3 alert. Here’s a look at what has changed in the last even days:

  • Upgraded to Level 3: Brown, Clermont, Muskingum
  • Downgraded to Level 2: Allen, Medina

Since the pandemic began, there have been 105,426 total confirmed and probable cases of COVID-19 in Ohio, resulting in 3,755 deaths. (Note: These numbers are as of August 13, 2020.)

Here are the Ohio counties with the most coronavirus cases:

  • Franklin: 19,124
  • Cuyahoga: 13,999
  • Hamilton: 9,917
  • Lucas: 5,544
  • Montgomery: 4,544

Here are the Ohio counties with the most coronavirus deaths:

  • Franklin: 533
  • Cuyahoga: 519
  • Lucas: 324
  • Hamilton: 260
  • Mahoning: 258

The governor also shared a map during his Thursday afternoon press conference comparing Ohio school districts’ back to school plans versus the state’s advisory map.

“It will be a challenge in red counties where students are also coming back in person,” DeWine said. “We, as communities, must work together to slow spread so that kids can stay in school.”

As the majority of school districts in Ohio are going back to school with in-person classes, DeWine and health department officials remind students, staff, and members of the community to “take care to back up, mask up, and wash up.”
