Over 120 health care workers from one hospital in California have been asked to stay home over fears they may have been exposed to a coronavirus patient.

A woman is currently being treated at the University of California Davis Medical Center for confirmed case of COVID-19. The patient didn't have any relevant travel history or any exposure to another known patient.

A total of 124 health care workers -- including at least 36 nurses -- have been forced to self-quarantine after possible exposure to the coronavirus patient, the National Nurses United union announced Friday.

The health care workers have been asked to stay home, according to a press release from the union.

"Despite University of California medical facilities being generally better prepared and equipped to treat challenging medical cases, the recent UC Davis Medical Center COVID-19 case highlights the vulnerability of the nation’s hospitals to this virus and the insufficiency of current Centers for Disease Control guidelines," the union said in the press release.

A spokesman at UC Davis Health tells CNN they do not have a comment at this time.
