(WTNH) — Central Connecticut State University closed campus suddenly Thursday morning due to a report of a student who may have had contact with an individual being tested for COVID-19. The student’s test came back negative Thursday afternoon.

The university president sent a letter to students emphasizing that the negative test did NOT mean the school was in the clear:

We are now assessing another situation involving a student presenting with symptoms and whose family member recently returned from travel to a country deemed to be Level 3 (high risk) by the Centers for Disease Control. We will continue to monitor this latest situation closely and will share additional information when it becomes available.

Zulma R. Toro, CCSU President

According to university officials, they were notified of the original case Thursday morning and a mobile quarantine unit was put in place. Additional custodial staff has been issued for deep cleaning and sanitization.

News 8 confirmed the person being tested had no affiliation with the school. One of the students was sent home from their job following the news.

The university calls for students and staff to follow the necessary steps and health precautions administered by the CDC.
