CARSON CITY, Nev. (AP) — Nevada health officials reported 491 more confirmed cases of coronavirus on Monday and one more known death.

The cumulative number of statewide COVID-19 cases now is 22,909 with 537 known deaths.

The number of cases has risen steadily since Nevada reopened casinos and other businesses in limited fashion in early June, prompting Gov. Steve Sisolak to implement a statewide face-covering mandate June 26 to curb the spread of the virus.

On a call with reporters Monday, Nevada COVID-19 response director Caleb Cage said officials were disappointed by the number of businesses found not to be in compliance with the mandate but needed more time to evaluate its effectiveness.
