Gov. Tom Wolf on Wednesday placed all of Pennsylvania under an order to stay at home, dramatically expanding the geographic footprint of the quarantine as state officials combat the coronavirus pandemic.

In one stroke, Wolf added 34 counties to his stay-home edict, meaning that residents of all 67 of Pennsylvania’s counties must now stay home as much as possible to help slow the spread of COVID-19.

With coronavirus infections continuing to rise dramatically in the state, with nearly 1,000 new confirmed cases reported Wednesday, Wolf called a statewide quarantine “the most prudent option."

“We appreciate the shared sacrifice of all 12.8 million Pennsylvanians; we are in this together,” Wolf said in a statement.

Residents may leave their homes for a number of reasons that include working at a business that’s still open, going to the grocery store or pharmacy, visiting a doctor, caring for a relative or heading outside to exercise. Police will continue to focus on informing residents of the order rather than on enforcement, according to the governor's office.

The order will last at least through April 30. Separately, schools and nonessential businesses are closed until further notice.
