More than 50 students at New Canaan High School are in quarantine after officials say four students tested positive for COVID-19.

Superintendent Bryan Luizzi says all of those students are currently learning from home.

New Canaan High School remains open under its hybrid schedule.

Luizzi says contact tracing was done on Sunday.

As a result, the district determined both classmates and teammates of the students who contracted the virus may have been exposed and need to quarantine.

Two staff members in the district are also in quarantine.

"There were very few quarantines that we had to do because of close contact in the school itself. Most of the people that are under quarantine are there because of contact through youth sports and other extracurricular strategies," Luizzi says. "People can follow all of the strategies and still get sick. And so, yeah, we are working with our students, working with everybody, our parents and all to help them understand that we recognize that these things happen and it's no personal failing if you get sick."

Luizzi adds that the building is cleaned extensively every day.

Meantime, the siblings of the students who tested positive who attend other schools in the district are quarantining as well.
