An MSU Denver employee has tested positive for COVID-19, President Janine Davidson announced in an email to students, faculty and staff Tuesday.

The employee was last on campus on March 11, according to the email, and has been in self-isolation at home since. MSU Denver announced its move to online-only classes on March 9, two days before the employee’s last day on campus. Classes were moved to online-only on Monday, and nine buildings on campus will close at 5 p.m. Tuesday.

“While we hoped we might avoid this scenario by enacting preventative measures throughout March, we have also been actively planning for this possibility for some time now,” Davidson wrote in the email. “We are working with the Health Center at Auraria and Denver’s Department of Public Health to investigate further details, including the risk of exposure.”

Although some buildings have closed and classes are online, campus as a whole remains open. The university has already begun cleaning and sanitizing since the first positive case was announced, Davidson said. Students can access resources for internet access, counseling and healthcare here.

Will Simpkins, vice president of student affairst at MSU Denver, tweeted that people who may have come in contact with the employee have already been notified.
