LOWER MERION TOWNSHIP, Pa. (CBS) — A COVID outbreak among Harriton High School students is spreading. Tonight, the Lower Merion School District told parents six more Harriton students have tested positive for the virus, and more students are quarantining.

The district says the cases appear to be related to a large social gathering over the weekend.

Harriton plans to return to full in-person instruction on Monday.
