Nevada reported 507 new coronavirus cases on Thursday, its highest one-day increase since the pandemic began.
The figure marks a 9% jump from the previous highest jump, recorded on Tuesday.
This brings the state's total to 14,859 infections, according to the Department of Health and Human Services.
Yesterday, Gov. Steve Sisolak issued a mandatory order for people to wear face masks in public, starting Friday, and cited the spike in positive cases signaling a need for greater caution.
The state is now indefinitely postponing plans to enter the next stage in its reopening plan.
