HARRISBURG – Gov. Tom Wolf reminded Pennsylvanians that mask-wearing is required and critical to prevent the spread of COVID-19. He said the reason for the order to make mask-wearing mandatory when leaving home was put in place to protect all Pennsylvanians from the spread of COVID-19. This simple practice, combined with social distancing, hand washing, and staying home if sick, is paramount to stopping this virus from infecting more people. PA Health Secretary Dr. Rachel Levine signed an order mandating mask-wearing on Wednesday. It remains in effect.
