Virtual-only schooling at Craig High and Roosevelt Elementary schools has been extended to Oct. 2, the Janesville School District announced to parents Tuesday morning.

Both schools pivoted to online instruction only on Wednesday, Sept. 16, “to prevent a breakout of COVID-19.”

Face-to-face instruction originally was scheduled to continue at least through Friday, Sept. 25.

“This extension of online instruction is due to continued follow-up with close contacts of established positive COVID-19 cases and aligns with the recommendations from the Rock County Public Health Department ...,” the principals of both schools said in the letter to parents.

“A ton of new cases have not come in, but because of the high number of close contacts, we’re just trying to follow up on that to limit the spread,” district spokesman Patrick Gasper said.

Gasper said the district has 15 active coronavirus cases. Eleven will be closed after this week and four more by next week.

Of the 15, nine are in high schools, five in elementary schools and one is at the middle school, Gasper said.

No other schools are considering closure, he said.

Throughout the school closures, school lunches and breakfasts are available free for curbside pick-up at both schools from 11 a.m. to 1 p.m. Monday through Friday, the letter states.

This is in addition to the meal pick-up locations established at Edison, Franklin and Marshall middle schools.
