Students living in the University of Arizona's Colonia de la Paz dorm have been told to watch for symptoms after an employee tested positive for coronavirus.
The employee's most recent shift was on March 26, and the patient is recovering at home, the Housing and Residential Life office said.
Students who lived in the dorm on or after March 12 were sent the notice and told to self-monitor. Approximately 500 students are still living on campus.
"Elevated cleaning protocol in the affected areas have been in place since March 9th. Once we were made aware of the confirmed positive case, we issued an additional deep cleaning," the office's letter said.
On March 24, a notice was sent to all on-campus residents after a student tested positive for coronavirus upon returning home.
There have been eight identified cases within the UA community. The university said privacy policies prevent them from releasing further information.
