WASHINGTON, Pa. — Pennsylvania Health Secretary Rachel Levine issued an order Wednesday requiring residents to wear masks, with exceptions, when leaving their homes as COVID-19 cases are on the rise, especially in Allegheny County.

The order requires mask wearing indoors where the public is generally invited, including workplaces, the order states.

“This mask-wearing order is essential to stopping the recent increase in COVID-19 cases we have seen in Pennsylvania,” Gov. Tom Wolf said Wednesday. “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 followed Allegheny County setting another record-high number of new COVID-19 cases for one day Wednesday in a rise partly blamed on young adults crowding bars, as well as travel.

The county’s health department announced 110 new cases of the virus, surpassing Tuesday’s record-setting increase by one patient with the disease.

“New cases will continue to be assigned to case investigators to gather information from those individuals and then contact tracing will begin,” the department stated in a news release.

Washington County’s cases also continued to climb Wednesday by 11 new cases, taking the total to 230. Greene County remained at 41 cases since the counting began in March.

The order from Levine took place immediately Wednesday afternoon and remains in place until further notice.
