On February 2, the CDC confirmed the U.S.'s ninth case in a woman in Santa Clara County, California, who had recently traveled to Wuhan. This case is unrelated to the first case in Santa Clara.

On March 1, two cases were reported in Alameda and Solano Counties, in health care workers at the NorthBay VacaValley Hospital.

A fifth case was reported in a woman with chronic health conditions who is hospitalized; a sixth and seventh cases were reported in a couple who are both hospitalized, and who had recently traveled to Egypt.

On March 2, the Santa Clara County Public Health Department reported two new cases, bringing the total to nine. Both were household contacts of previously confirmed cases and were in home isolation. In Placer County, a healthcare worker who had close contact with a confirmed case in Solano County's NorthBay VacaValley Hospital was presumptively tested positive. In Sonoma County, a resident was presumptively tested positive after returning from a cruise ship that departed San Francisco to Mexico. In San Mateo County, an adult resident was presumptively tested positive; they were placed in isolation in a hospital. The source of exposure was reported as unknown.

12 new cases were reported on March 3. Public health officials in Santa Clara County, California confirmed two new cases of unknown origin there.

On March 4, California public health officials in Placer County reported a second confirmed case in an "older adult" resident with underlying health conditions who was aboard the Princess Cruises cruise ship Grand Princess on a cruise to Mexico that departed San Francisco on February 11 and returned on February 21.

This marked the eleventh death in the United States attributable to coronavirus, the first death in the U.S. attributable to coronavirus outside Washington state, and the first death in California attributable to coronavirus. The source of the new case's infection appears to be the same as that of a resident of Sonoma County who tested positive on March 2 and who was also aboard the Grand Princess cruise ship on the same dates. In relation to this, Governor Gavin Newsom declared a State of Emergency in California. Consequently, Princess Cruises, the owner and operator of the Grand Princess cruise ship, working with the CDC, the state of California, and public health officials in San Francisco, terminated a port call in Ensenada, Mexico planned for March 5 and ordered the cruise ship to return to San Francisco over concerns about the potential for an outbreak of coronavirus aboard the cruise ship. Sixty-two passengers still aboard the Grand Princess who may have made contact with the Placer County case that died earlier in the day were quarantined aboard the cruise ship at the request of the CDC.

In addition, public health officials in Sunnyvale reported that the death of a 72-year-old man found unresponsive in his home was under investigation as a possible second death in California attributable to coronavirus after they subsequently learned from one of the man's family members that the man had been aboard the same Grand Princess cruise to Mexico linked to two other coronavirus cases in Sonoma and Placer Counties.
