“This mask-wearing order is essential to stopping the recent increase in COVID-19 cases we have seen in Pennsylvania,” Gov. Wolf said in a press release.

“Those hot spots can be traced to situations where Pennsylvanians were not wearing masks or practicing social distancing – two practices that must be adhered to if we want to maintain the freedoms we have in place under our reopening.”

The order requires face masks to be worn in several different settings, including if you’re outdoors and can’t stay 6 feet away from people who aren’t family members, if you’re inside a public place or if you’re at work.

There are exceptions that can be found in the order. People with exceptions aren’t required to show documentation.

“It is essential that Pennsylvanians wear masks to prevent the spread of COVID-19,” Secretary of Health Dr. Rachel Levine said in a press release.

“While cases increase in some areas, we cannot become complacent. My mask protects you, and your mask protects me. Wearing a mask shows that you care about others, and that you are committed to protecting the lives of those around you.”
