As COVID cases continue to surge, the mask mandate is coming back in Nevada. Gov. Steve Sisolak Tuesday issued the directive in alignment with new recommendations from the CDC. Mask use is mandated for all, regardless of vaccine status. The mandate will go into effect at 12:01 a.m. Friday. The Governor says based on CDC data, 12 of Nevada’s 17 counties are deemed as having substantial or high transmission, including Carson, Churchill, Clark, Douglas, Elko, Esmeralda, Lincoln, Lyon, Mineral, Nye, Washoe and White Pine.
