A guest staying at The Mirage on the Las Vegas Strip tested positive for coronavirus, MGM Resorts International said Wednesday.

In a statement, the company said the person from New York was an attendee of the Women of Power Summit, which was held at The Mirage from March 5-8.

“Upon learning of the individual’s symptoms, Mirage staff worked in coordination with the state health district to implement MGM Resorts’ health and safety protocol,” the company said.

“We are currently coordinating with the Southern Nevada Health District to notify guests and employees who may have had close prolonged contact with the individual and are directing our employees to follow all self-quarantine requests.”

The company said, “professional cleaners with expertise in this area are deep cleaning and sanitizing the individual’s room.” Access to the room remains restricted as “it undergoes this comprehensive cleaning and disinfectant process.”

MGM said, “we wish the individual well and offer our support in her recovery.”

On Tuesday, MGM shut down its Yonkers Raceway outside New York City after a worker with the Standardbred Owners Association tested positive for the coronavirus and had passed away.

The harness track, which the Las Vegas-based company acquired last year along with the adjacent Empire City Casino, was closed and employees who worked in the immediate area as the affected worker were asked to self-quarantine.

A spokesman for MGM said the Empire City Casino was not affected by the closure since the building is separate from the racetrack.

Shares of MGM Resorts closed at $18.08 Wednesday on the New York Stock Exchange, down $2.71 or 13.04 %.
