After several large parties were held last week, 20 students were found to test positive for COVID. A medical team was deployed to test all students on Friday, and a total of 71 cases were found.
As of Sunday morning, there were 105 positive cases on campus -- which makes up for 3% of students and faculty on campus this year.

School officials say more suspensions are likely as investigation into off-campus parties continues.
The increase in cases are a warning to school districts across the state, Gov. Andrew Cuomo said.
"Colleges are the canary in the coal mine," he said. "I think what we're seeing in colleges we're going to see in the K-12 setting when those schools start to reopen."
