The University of Notre Dame says it will move undergraduate classes online for the next two weeks and close public spaces on campus. That announcement follows a spike in COVID-19 cases on the South Bend campus – 80 new cases were reported this week, raising the total number of infected students to 147.

Notre Dame says it tested nearly 12,000 students before classes began, and recorded a 0.3 percent positivity rate. Just more than a week since, that positivity rate increased to 19.1 percent. The university says most cases can be traced back to off-campus parties.

Notre Dame President Reverend John Jenkins says disciplinary action will not be taken on any student parties that have been reported through contact tracing.

“If however, we learn of a serious violation of our policies from other sources, we will take disciplinary action,” he said.

The university says, until further notice, off-campus students should not visit campus. After September 2, officials will make the decision whether to return to in-person instruction or send students back home.
