Schellhas said the student is in self-quarantine at home and does not have any siblings at the school, does not participate in school athletics, and does not use the bus system to get to school.
Three school students who visited this student last week are now self-quarantined for at least two weeks, at the direction of the Montgomery County Department of Health. They are currently not showing any symptoms and will not be tested unless they begin to experience symptoms, Schellhas said.
Germantown Academy is closed through Wednesday. After Wednesday, students will have class online until next Tuesday.
No presumptive cases in Pennsylvania have yet been confirmed by the CDC.
