For the first time in nearly six decades, Las Vegas casinos will go dark — shutting down for at least 30 days in an effort to curb the spread of coronavirus.

Nevada Gov. Steve Sisolak announced a statewide order late Tuesday mandating that all “non-essential” businesses such as bars, movies theaters and gyms close their doors for one month starting at noon Wednesday.

“This is only common sense,” Sisolak said in prepared remarks. “If your business brings groups of people together, it should not be open.”

All casinos, slot machines and gaming activities across Nevada were to be shut down at midnight Tuesday. Restaurants and bars at casinos in the state must also comply with the new restrictions, Sisolak said.

The governor acknowledged that some people would not agree with the move, but said it was made after consultation with White House officials, the Centers for Disease Control and Prevention and industry leaders.

“I know the impacts of this decision will reach far and wide into the homes and lives of our Nevada families,” said Sisolak, a Democrat. “This was not an easy decision to make.”

The mandate follows similar measures taken by governors in more than 10 states to curb the spread of COVID-19, which has infected at least 56 people in Nevada as of Wednesday, according to a Johns Hopkins University database.

MGM Resorts International and Wynn Resorts announced plans on Monday to close their doors beginning on Tuesday.

“It is now apparent that this is a public health crisis that requires major collective action if we are to slow its progression,” MGM CEO and chairman Jim Murren said in a statement.

MGM has also already begun to cut its losses with “significant furloughs and layoffs,” the Las Vegas Review-Journal reported.

Casinos were last closed in Las Vegas for the funeral of President John F. Kennedy on Nov. 25, 1963, a history professor at the University of Nevada told the Associated Press.

Sisolak’s announcement marks the first time all Nevada casinos have been ordered to shut down, professor Michael Green said.
