The St. Clair County Health Department endorses the updated isolation and quarantine guidance from the Michigan Department of Health and Human Services (MDHHS) and Centers for Disease Control and Prevention (CDC). Guidance is based on the best available science, data, and information available at the time. These are recommendations. Please contact your regulatory agency for questions about what is currently mandated for your industry. 

Although businesses are no longer required to report COVID-19 positive employees to the Health Department, please consider reporting a positive case here. 

Health Department staff are available to assist with questions about COVID-19 cases or concerns. Please email

Although previous COVID-19 prevention strategies are no longer required for most settings, the St. Clair County Health Department strongly encourages each facility to evaluate their operations, and to follow CDC and OSHA recommendations to prevent disease spread and protect worker and patron health and safety. (Note that healthcare settings do have OSHA and MIOSHA requirements related to COVID-19.)
