Houston's Rice University has asked a small group of its employees and students to self-quarantine "out of an abundance of caution," according to a release from the school.

The university said the measure is due to an "employee's possible exposure to the coronavirus while on overseas travel," the release said.

Rice University did not disclose what country the employee traveled to but said it was not one on the CDC's restricted travel list; which includes China, Iran, Italy, South Korea and Japan. 

The university's administration is "not planning to suspend campus operations, events or classes," according to the release.

"We ask that all members of our community take steps to ensure that we all stay as healthy as possible," the release said.
