MIOSHA is recommending that businesses in these areas and other counties with a substantial or high risk require both workers and customers wear masks.
"As transmission rates accelerate rapidly in many Michigan counties, Michigan employers should monitor the spread of COVID-19 in their local communities and follow the CDC’s guiding principles for both fully vaccinated and unvaccinated people to ensure we are all doing our part to keep workplaces safe for employees and customers," said COVID-19 Workplace Safety Director Sean Egan.
