Pennsylvania lifted its mask mandate earlier today, more than 14 months after Gov. Tom Wolf began requiring people to wear face coverings whenever they left home to prevent the spread of COVID-19. The Department of Health will no longer require unvaccinated people to wear masks in public, though it said businesses, health care facilities, prisons and other places may still require them. The U.S. Centers for Disease Control and Prevention also requires masks on planes, trains, buses and public transportation hubs.
