Nevada’s casinos will have to stay shut a little while longer to give containment of the COVID-19 pandemic a fighting chance.

On Wednesday, Nevada Gov. Steve Sisolak issued a formal Stay at Home directive to state residents, forbidding them from leaving their homes for “nonessential activities” in the hopes of minimizing further spread of the COVID-19 coronavirus.

Sisolak also extended the nonessential business, gaming and school closures he originally issued on March 17. That original order required all gaming venues to shut their doors for 30 days but this has now been extended through the end of April. Sisolak’s office said the extension “mirrors the latest guidance from the federal government.”

On Tuesday, Sisolak sent a formal appeal to US President Donald Trump seeking a disaster declaration that would enable Nevada to qualify for additional federal assistance. Nevada had nearly 1,300 confirmed COVID-19 infections and 31 deaths as of Tuesday. Clark County, in which Las Vegas is located, accounted for 961 of those infections and 28 of the deaths.
