Chester County High School Halts Operations to Verify Staff Vaccination Amid Measles Surge
Oxford Area High School in Chester County, Pennsylvania, closed on October 9, 2026, after a confirmed measles case was linked to the school community. The closure allows health officials to verify staff vaccination records, as some employees lack documentation from decades ago. Meanwhile, the Chester County Health Department issued exposure warnings for two CVS pharmacies and a Giant supermarket visited by the infected individual on October 4. Pennsylvania has recorded over 1,100 measles cases, with Chester County leading the Philadelphia region with 86 confirmed cases.
