Nearly half of U.S. states are seeing upticks in new coronavirus cases, leading some state officials to order the reimposition of mask wearing for citizens. In California on Thursday, Gov. Gavin Newsom announced that people will be required to wear masks in any indoor space, while Oregon Gov. Kate Brown issued a similar order for people living in seven counties there, CNN reported. North Carolina and Arizona are considering similar measures. Those four states -- along with Alabama, Florida, Nevada, Oklahoma, South Carolina and Texas -- are experiencing the highest week-long average rise in new daily cases seen in their states since the pandemic began, according to a CNN analysis of Johns Hopkins University data.
