Three additional cases of novel coronavirus were confirmed in Riverside County Monday, bringing the county's total to six cases.

Riverside University Health System-Public Health said the three individuals who tested positive for novel coronavirus are residents in the Coachella Valley. All three are believed to have been infected as a result of travel into areas where COVID-19 has been confirmed, or through contact with a known case.

Dr. Cameron Kaiser, a public health officer with Riverside County, said that two of the individuals have been isolated at home while the third is being cared for at a Coachella Valley hospital.

The announcement comes shortly after Kaiser announced over the weekend Riverside County’s first locally-acquired case of a patient who is being cared for at Eisenhower Health in Rancho Mirage. Public health investigators have not been able to determine how the individual was infected, Kaiser said, so it is now considered a case of “community spread.”

Community spread means that an individual contracted the virus from a source of unknown origin.


Kaiser said he is recommending those in the Coachella Valley who are elderly and have underlying health conditions, including individuals who are HIV positive, limit non-essential travel and avoid large public gatherings.

In addition, Riverside County now has a second confirmed case arising from the Diamond Princess cruise ship. This former passenger is also receiving treatment at a Northern California hospital, and like the other former passenger from the Diamond Princess, has not been to Riverside County since leaving the ship.

This brings the total number of Riverside County COVID-19 cases to six.

“We are very concerned for the individuals who have contracted the virus in Riverside County,” said Dr. Kaiser. “We wish these folks, and the two residents in Northern California, a full recovery. Our thoughts are with them and their families at this time.”

Public health recommendations for all Riverside County residents during community spread:

• Practice social distancing, which is remaining out of places where people meet or gather and avoid using public transportation, if possible.

• Do not attend work, school or events when sick. Stay home.

• Cough into your elbow or tissue.

• Wash hands frequently and use hand sanitizer often.

• Stay away from anyone who is sick.

On Sunday, Dr. Kaiser declared a public health emergency, which will support the county’s planning and response efforts. The emergency declaration is set to be ratified by the Riverside County Board of Supervisors at their regularly scheduled meeting on Tuesday, March 10.
