Governor Whitmer is expected to provide an update on the state's response to COVID-19 Thursday.
Earlier this week, she said she could "dial back" reopening the economy if cases continue to rise.
As of Wednesday, the state recorded its highest daily reported cases in 7 weeks, with 610 new cases and 10 deaths.
A non-profit called "COVID Act Now" once applauded the state for flattening the curve, but says Michigan is now on pace for an outbreak.
"Politicians going in and medaling with protocol and CDC practices is a recipe for disaster," said Gov. Whitmer.
The governor is promising to stay the course on the state's efforts to minimize the spread of COVID-19.
A map from June 17 showed the state was considered "on track" to contain COVID-19 infections.
"The reason Michigan has been able to push our curve down is because we're listening to scientists. Not threats, not politicians," Gov. Whitmer said. "We got to make decisions on keeping people safe. And we got to ask everyone to continue to do their part."
But a new map representing July 9, shows the state is "at risk."
The maps are from a non-profit group called "COVID Act Now," which is tracing Michigan's progress on tackling the virus.
The state's taken a step backwards, causing state health officials to downgrade several regions, including metro Detroit dropping to medium risk, alongside the Northern Lower Peninsula and the UP.
"We've had some success, but there are concerning trends all across this nation," the governor said. "The last thing I want to see in Michigan is an outbreak that keeps us moving forward, getting our kids in school, we have to take this masking up campaign seriously."
The governor says she's also calling for a mask-up campaign nationally to help stop the spread.
