Scripps Health said in a short statement Tuesday morning that it is treating the county’s first case local COVID-19 case.

The patient, who is receiving treatment in isolation at Scripps Green Hospital in Torrey Pines, tested positive for the disease caused by novel coronavirus on March 9. The case was announced by county health department officials Monday night in a hastily-called news conference.

For now, the patient’s infection is considered a “presumptive positive” because it has not yet been confirmed by the U.S. Centers for Disease Control and Prevention.

Scripps said it took “immediate steps” to place staff exposed during the encounter on home quarantine. Green and the adjacent Scripps Clinic Torrey Pines remain open for business, and Scripps says they’re “safe for patient care and all appointments.
