Ohioans will be required to wear facial coverings in public in 19 of the state’s 88 counties beginning 6 p.m. Friday (July 17) based on the latest data from the state’s coronavirus warning system. To help communicate with employees and customers, the Ohio Department of Health has made available numerous posters and signs for businesses to download and print. This includes signs encouraging the use of face coverings, as well as “face coverings are mandatory” signs for businesses in counties that are at levels 3 or 4 under the Ohio Public Health Advisory System.
