HARRISBURG (AP) — All Pennsylvania residents must stay home as much as possible to help slow the spread of the coronavirus, Gov. Tom Wolf said Wednesday as he dramatically expanded the footprint of the quarantine to include the entire state.

The Democratic governor added 34 counties to his existing stay-at-home order, meaning that residents of all 67 of Pennsylvania’s counties are now asked to stay put unless they have a legitimate reason to go out.

The expanded order will take effect at 8 p.m. Wednesday and last through at least April 30.
