On July 2, Gov. Mike DeWine announced a public health alert system aimed at assessing the coronavirus spread in each county of the state. The Ohio Public Health Advisory System has four, color-coded levels to represent the severity of spread in each county. State health officials created seven indicators to determine which alert level each county is in. A summary is available on the Ohio Department of Health (ODH) website. The risk levels range from Level 1-4:
- In Level 1, or yellow, counties meet zero or one of the indicators. Level 1 counties have active exposure and spread of coronavirus. It is the least severe level.
- In Level 2, or orange, two or three indicators are met. Counties in Level 2 have increased exposure and spread and residents should exercise caution.
- In Level 3, or red, counties meet four or five indicators. The risk is very high for exposure and spread and residents should limit activities as much as possible and wear a mask when they go out in public.
- In Level 4, or purple, six or seven indicators are met. Counties have severe threat for exposure or spread of the virus and residents should only leave home for supplies and services. Level 4 is the most severe level.
