Pennsylvania Governor Tom Wolf, however, is adding several new measures, including testing and quarantining for people coming into the state (with some exceptions) and requiring the wearing of masks in your own home if you have company over.
“Strengthening masking order. Masks are still required. Indoors: masks now required anytime you’re with people outside of your household, even if you’re socially distant. Applies to all indoor facilities + if you have people in your home not part of your household”
