Jackson County Public Health officials on Saturday confirmed a third COVID-19 case, saying the patient was isolated at home while fighting the infection.
A few hours later, SIU Chancellor John Dunn reported the case - a male in his late teens - is an SIUC student, and in the same residence hall as the first case. As a result, Dunn says all 21 residents in the residence hall on the west side of campus - known as Thompson Point - are being quarantined.
Dunn says the students are "fully supported" with food an other necessities, including from the university's health service.
In the message to the campus community, Dunn thanked the staff who are continuing their work both on and off-campus, including faculty who are changing their teaching plans mid-semester in order to deliver classes online.
SIUC extended its Spring Break by a week to allow for students, faculty, and staff to prepare for remote learning. Since that time, the university has encouraged all employees - including students - to work from home where possible.
While residence halls, dining, and other student services were not closed, the university reports most students chose not to return to campus after the extended break. SIU's Board of Trustees is holding a Special Meeting on Monday to discuss giving President Dan Mahony the authority to issue refunds in some cases.
