A third Cherokee County high school announced plans Sunday to temporarily end in-person learning after 500 students were quarantined and 25 tested positive for COVID-19.

Creekview High School in Canton is suspending in-person learning effective immediately through Aug. 31, according to a spokeswoman for the county school district.

The decision came after more than a quarter of the 1,800 students taking in-person classes at the high school were directed to quarantine. The school district said it’s expecting the number of quarantined students to “significantly increase” once pending tests are returned.
