One patient may be the first case of person-to-person spread due to a lack of travel history, according to Ferrer. The second patient has a history of travel to Japan.

Ferrer also announced the U.S. Centers for Disease Control is recommending people to not go on any cruises effective immediately, Ferrer said. Previous guidance from the CDC was aimed primarily at Asian countries.

Three additional coronavirus cases were confirmed Monday afternoon in Riverside County. Health Officer Dr. Cameron Kaiser said the cases were located in the Coachella Valley.
