Nevada has 445 more COVID-19 cases, making Saturday the second straight day the state has reported a new 24-hour high since the start of the pandemic.
The state had reported 410 new cases Friday, surpassing the previous single-day jump of 379 four days earlier.
The state Department of Health and Human Services says there have been 12,931 cases and 486 deaths, including eight reported Saturday. Las Vegas and surrounding Clark County account for fourth-fifths of the cases and deaths.
The number of new cases has climbed as Nevada has expanded testing and reopened casinos, restaurants and other businesses. Gov. Steve Sisolak said Friday he will consider toughening rules on face masks. Nevada now requires business employees to use masks, but does not require customers to do so.
