Come Monday, all indoor public places in New York that do not require proof of full vaccination for entry must implement a mask mandate, Gov. Kathy Hochul announced Friday. She called it a "major action" to address the worst COVID surge the state has seen in more than half a year across all of the key indicators. The decision was based on mounting concern of the state's weekly seven-day case rate and rising hospitalizations, Hochul said. Noncompliance comes with fines of up to $1,000 per violation. The order will be reassessed on Jan. 15. News 4's Linda Gaudino reports. #mask #vaccine #mandate #covid #nbc4ny
