Detroit health officials say residents face a high risk of COVID-19 spreading in the community.
The Centers for Disease Control and Prevention report all of Wayne County, as well as Oakland, Macomb, and Washtenaw counties, fall into the high-risk category for community spread of COVID.
The CDC advises residents in the affected areas to wear a mask in all public indoor settings even if they are vaccinated against COVID.
The agency recommends extra precautions for those especially at risk of severe illness from the coronavirus, like elderly people or those with some pre-existing health issues.
Michigan's health department reported a spike in COVID-related cases and fatalities over the past week, but adds that increase looks higher than it should because of a delay in reporting past cases.
The CDC also recently loosened its overall guidelines regarding COVID, and no longer suggests that people socially distance or quarantine after being exposed to an infected individual.
