Chester County is the only county in Southeastern Pennsylvania to show an increase in new coronavirus cases when comparing the latest two-week period to the previous two-week period. That comparison is one of four new goals recently devised by the state health department to determine whether counties currently in the "yellow" stage of reopening can move to the less-restrictive "green" phase.
Change in total new cases by county, according to Pa. Department of Health data*:
| County | New cases, May 12-26 | New cases, May 26-June 9 | Change |
|---|---|---|---|
| Berks | 467 | 299 | |
| Bucks | 764 | 410 | |
| Chester | 549 | 657 | |
| Delaware | 1,132 | 465 | |
| Lancaster | 706 | 569 | |
| Montgomery | 1,225 | 971 | |
| Philadelphia | 3,196 | 1,976 | |
| Schuylkill | 123 | 63 |
