Update: All Three Detroit Casinos End Mask Mandate For Vaccinated Guests

Can you please rephrase this statement for me?

The story has been refreshed on Friday morning and will be continuously updated as additional information emerges.

MotorCity Casino Hotel & Sportsbook in Michigan is lifting its mask mandate for vaccinated guests this week as COVID-19 cases continue to decline.

In November of last year, MotorCity Casino became the first of the three Detroit retail casinos to reinstate the mask policy.

On Thursday, MGM Grand Detroit Casino & Sportsbook and Greektown Casino-Hotel & Sportsbook Lounge also took similar actions.

MotorCity Casino ends mask mandate at 8 a.m. Thursday

Starting at 8 a.m. on Thursday, Feb. 17, MotorCity Casino’s website stated that guests who have received complete vaccination will no longer be obligated to wear masks.

Guests who have not completed vaccination will still be mandated to wear masks. It is unclear whether proof of vaccination will be necessary, as Playinmichigan has not promptly responded to queries seeking clarification.

MotorCity Casino will be lifting the mask requirement for vaccinated guests, which has been in effect since November. However, the casino will continue to implement social distancing measures and enhanced cleaning protocols.

MGM Grand, Greektown lift mandate Thursday

On Thursday morning, MGM Grand Detroit took to its Twitter account to announce the lifting of the mandate for vaccinated guests.

Updated Mask Policy: Effective immediately, vaccinated individuals are no longer mandated to wear masks. We kindly request unvaccinated guests to continue wearing masks throughout their visit, although proof of vaccination will not be necessary.

Later in the day, an update was posted by Greektown Casino.

Updated Mask Policy: Vaccinated guests are no longer mandated to wear masks while visiting. However, guests who have not received complete COVID-19 vaccination are still required to wear masks. We sincerely thank you for your commitment to maintaining a safe environment at Greektown Casino-Hotel!

New COVID cases down significantly

The recent decline in new COVID-19 cases over the past few weeks is the reason behind the change in mask policy.

On November 23rd, when the mask policy was implemented, a record-breaking 8,502 new cases were reported.

According to the most recent update by the Michigan Health Department, there was an average of 1,793 new cases reported between Saturday and Monday (Feb. 12-14).

The current number of new cases is significantly lower compared to the highest point of 20,346 new cases recorded on January 6th this year.

For the first time since late September, Michigan has witnessed a 7-day average of new cases below 3,000.

The current 7-day average of new cases in Wayne County stands at 262, which reflects a significant decrease compared to the previous week’s count of 714.
