Lancaster County Public Schools will hold a Three Rivers Health district drive-through COVID-19 testing event at Lancaster Middle School on Saturday from 10:00 a.m. until 12:00 p.m. The event is open to all staff, students and families. Officials say testing is another layer in protection against COVID-19 and you should be tested if you’re symptomatic, recently traveled or attended a large event. If you need to be retested, you’re also urged to attend.
