Eleven individuals with ties to San Francisco's Laguna Honda Hospital have tested positive for COVID-19, health officials said Monday. Of the cases, nine are among staff and two are residents; all are in good condition.

"We expect the situation to unfortunately get worse," S.F. Public Health Director Dr. Grant Colfax said of the outbreak at the long-term care facility for the elderly, owned and operated by the San Francisco Department of Public Health.

Colfax said that based on the data from around the world, long-term care facilities are at the highest risk for outbreaks.

“I expect more cases of coronavirus in the Laguna Honda community among staff and residents," he said.

Laguna Honda is calling in additional resources to address the situation, including staff and expertise on long-term care and infection control from the DPH system. UCSF and Sutter are being deployed to strengthen the response.

Colfax said Monday the Centers for Disease Control and Prevention is sending infectious disease doctors and two epidemiologists. In addition, it has assigned a dedicated staff member at the CDC headquarters in Atlanta.

The two patients who tested positive are in a unit of the hospital with 60-plus patients. The doors of this area have been closed and are guarded by police to stop patients from leaving.
