Unvaccinated students and staff at Oxford Area High School, along with anyone who cannot show proof of measles immunity, must stay out of school and school events for 21 days after a confirmed measles case tied to the campus community. The Oxford Area School District announced the decision late Thursday, Oct. 8, and closed the building Friday so officials could verify vaccination records for every staff member.
Officials are also tracing exposures beyond the school. The Chester County Health Department warned that people who visited two CVS stores and a Giant supermarket along Baltimore Pike in Kennett Square and West Grove on Sunday, Oct. 4, may have been exposed to the virus.
