Empty shelves at a San Francisco grocery store after panic buying
The 2020 coronavirus pandemic in California is part of the ongoing worldwide pandemic of coronavirus disease 2019 (COVID-19). The first case of COVID-19 in California was confirmed on January 26.[3] A state of emergency has been in place in the state since March 4. A mandatory statewide stay-at-home order was issued on March 19. As of March 31, 2020, the CDPH says that there have been 8,155 confirmed cases and 171 deaths in the state.[2]
^On March 14, 2020, CDPH started reporting the numbers as of 6 PM instead of 8 AM. More cases may be reported due to a longer reporting interval that is more than 24 hours (i.e. 34 hours).
^On March 20, 2020, CDPH started reporting the numbers as of 2 PM instead of 6 PM. Fewer cases may be reported due to a shorter reporting interval that is less than 24 hours (i.e. 20 hours).

January–February
On January 26, the CDC confirmed the first case in California, the third case in the U.S. The person, a man in his 50s, was released from the hospital in Orange County on February 1 in good condition to in-home isolation.[3] On January 31, the CDC confirmed the seventh case in the U.S., a man in Santa Clara County, who had recently traveled to Wuhan.[54] The man recovered at home and was released from in-home isolation on February 20.[55]
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 was unrelated to the first case in Santa Clara.[57] On the same day, the CDC reported the tenth and eleventh cases in San Benito County, including the second instance of human-to-human transmission.[58]
On February 5, the U.S. evacuated 345 citizens from Hubei Province and took them to two air bases in California, Travis Air Force Base in Solano County and Marine Corps Air Station Miramar, San Diego, to be quarantined for 14 days.[59][56] The evacuees from one more government evacuation flight on February 6 were also taken to bases in Nebraska and Texas.[56][60]
On February 15, the government evacuated 338 U.S. nationals stranded aboard the cruise ship Diamond Princess, which had been held in quarantine in Yokohama, Japan.[61] Fourteen of those repatriated people were infected with the virus.[62] Five more nationals who were also reported as being infected were evacuated from the ship the following week, and were quarantined at Travis Air Force Base; several more cases among the evacuees were later confirmed.[63]
On February 26, a case of unknown origin was confirmed in a resident of Solano County.[64][65] The UC Davis Medical Center in Sacramento said that when the person was transferred there on February 19, the medical team suspected it was COVID-19 and asked the CDC to test for SARS-CoV-2. The CDC initially refused since the person, who had no known exposure to the virus through travel or close contact with a known infected individual, did not meet the criteria for testing. The person was ultimately tested on February 23; the test results returned positive on February 26.[66]
After this first case of community transmission in the U.S., a case with no known origin recognized in Solano County, California,[67] the CDC revised its criteria for testing patients for coronavirus, and on February 28 began sending out the new guidelines for healthcare workers. CDC director Dr. Redfield said the new health recommendation should be when a clinician or individual suspects coronavirus, then we should be able to get a test for coronavirus.[68][69]
March
March 1–2
On March 2 two cases were reported in Alameda and Solano Counties, in health care workers at the NorthBay VacaValley Hospital. The workers were exposed to the patient in the case reported February 26 in Solano County.[70] In Santa Clara County, three more cases were reported, bringing the total number of cases in the county to seven: a fifth case was reported in a woman with chronic health conditions who is hospitalized; the sixth and seventh cases were reported in a couple who are both hospitalized, and who had recently traveled to Egypt.[71]
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.[72] 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.[73] In Sonoma County, a resident was presumptively tested positive after returning from a cruise ship that departed San Francisco to Mexico.[74] In San Mateo County, an adult resident was presumptively tested positive; they were placed in isolation in a hospital.

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.[83] Although initial reports indicated that the new case had been hospitalized in "critically ill" condition, public health officials in Placer County subsequently reported the new case's death later on the same day. 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.[84][85] 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 cruise ship Grand Princess on the same dates.[86][87] In relation to this, Governor Gavin Newsom declared a State of Emergency in California.[88] Consequently, Princess Cruises, the owner and operator of the cruise ship Grand Princess, 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 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.[89] In addition, eleven passengers and ten crew members were exhibiting potential symptoms of coronavirus, and Grand Princess was ordered by the state of California to remain offshore while test kits were being airlifted to the cruise ship.[90][91][92][93][94][95] Public health officials in Santa Clara County confirmed three new cases.[96]

Neither of the patients recently traveled nor made contact with other coronavirus patients.[98] Six additional cases of coronavirus were reported in Santa Clara County,[99] while six AT&T retail stores in San Diego were closed after an employee at one of the stores tested positive for coronavirus.[100][101] 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.[102][103][104]
In Alameda County, officials confirmed a second case on March 6, a former passenger of the cruise ship Grand Princess.[105] Three new cases were reported in Contra Costa County, with two being former passengers on Grand Princess.[106] Three new cases were reported in Placer County; all were passengers on Grand Princess.[107] Four new cases were reported in Santa Clara County, bringing the county's total to 24.[108] In Sunnyvale, Lockheed Martin reported that one of its employees in its Sunnyvale office tested positive for coronavirus.[109]Yolo County reported its first case, through community transmission.[110]

In a letter to families, the school district announced no students or employees had tested positive.[115]
In Madera County, officials confirmed the county's first coronavirus case from a person who had been aboard Grand Princess. Their spouse, whom they were with on the cruise, was also being monitored. Both were taken to the Madera Community Hospital and were reported as in monitored isolation.[116] In Fresno County, two people returning from Grand Princess were quarantined and tested for the virus, with one person testing positive, making them the county's first confirmed case.[117]

Shortage of gear
Many doctors and nurses and EMS workers expressed fears and frustrations at being asked to wear the less effective surgical masks and at the overall lack of proper masks, gowns and eye gear which imperils their ability to fight the coronavirus and puts their own lives at risk.[207][208]
The medical workers are concerned that the shortages have not been addressed by the CDC, whose changing guidance for healthcare over how to stay safe themselves and protect the patients remained unclear and misleading, and that the new recommendations are borne of political expediency instead of science.[207]
Mid-March, the CDC changed its guidance from stating earlier that regular surgical masks cannot protect a healthy person from infection to now saying that regular masks are "an acceptable alternative" when examining or treating a coronavirus patient. The change came given the shortages of the N95 masks. The American Nurses Association sent a letter to Congress, saying there is concern
"that C.D.C. recommendations are based solely on supply chain and manufacturing challenges," and "that these recommendations do not offer strategies to address the limited manufacturing and supply chain of necessary personal protective equipment."[207]
Hospitals and ventilators
In 2020, hospitals in California hired rental ventilators and rationed N95 masks, raising complaints from nurses. California in 2006 had stockpiled three 200-bed mobile hospitals with 50 million N95 respirators, 2,400 ventilators, and 21,000 additional patient beds, but the governor at the time, Jerry Brown, disposed of them in 2011 as a budget cutting measure.[209]
Community response

Maker Nexus, a non-profit maker space in Sunnyvale, began making face shields to donate to local hospitals and other health care facilities, using its 3D printers and laser cutters. This effort grew rapidly as individuals in the Bay Area began using home-based 3D printers and bringing the result to Maker Nexus to complete the shields and deliver them to the recipients.[213][214] By the first of April, more than 300 community members were using their home 3D printers for this effort.[215] Together with other groups and individuals, the maker space is also making cloth face masks to substitute for N95 masks in non-critical applications and helping to coordinate face mask deliveries.[216]
