As coronavirus caseloads continue to surge across the South and West, officials are hoping that mandatory mask-wearing can stop a rapidly-spiraling outbreak in its tracks. On Wednesday, Arizona Gov. Doug Ducey (R) reversed his previous stance and gave local governments the authority to require face coverings be worn in public, while Oregon Gov. Kate Brown (D) said that masks would be mandatory for more than half her state’s population. Several Southern cities — including Memphis, Montgomery, Ala. and Fayetteville, Ark. — have also made masks compulsory in recent days.
