The Oregon Health Authority has disclosed 10 new coronavirus cases at schools in Clatsop County.

All of the virus cases involved students, according to the health authority’s weekly outbreak report. The majority of the cases were from the Knappa School District, with seven from Hilda Lahti Elementary School and one from Knappa High School.

Knappa Superintendent Bill Fritz said the virus cases were tied to events outside of school and there is no concern of person-to-person spread on school property.
