Coronavirus cases are rising in Michigan and COVID-19 hospitalizations have spiked 80% in recent weeks, climbing in all regions of the state, health officials warned Tuesday.

“It is very possible that this is the beginning of a second wave,” said Dr. Joneigh Khaldun, the chief medical executive and chief deputy director for health for the Michigan Department of Health and Human Services.

“That is why we are asking everyone to remain vigilant and do these basic things: wearing masks, avoiding the social gatherings. It’s very important.”
