A Three Rivers Health District COVID-19 testing event takes place this Saturday at Lancaster Middle School from 10:00 a.m. until 1:00 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’re beyond the 5th day of quarantine and need to be retested you’re also urged to attend.
