California government response to the COVID-19 pandemic

The government of California initially responded to the COVID-19 pandemic in the state with a statewide lockdown, the first of its kind during the COVID-19 pandemic in the United States. As the pandemic progressed in California and throughout the rest of the country, the California government, following recommendations issued by the U.S. government regarding state and local government responses, began imposing social distancing measures and workplace hazard controls.

Background
On December 31, 2019, China reported a cluster of pneumonia cases in its city of Wuhan. On January 7, 2020, the Chinese health authorities confirmed that this cluster was caused by a novel infectious coronavirus. On January 8, the Centers for Disease Control and Prevention (CDC) issued an official health advisory via its Health Alert Network (HAN) and established an Incident Management Structure to coordinate domestic and international public health actions. On January 10 and 11, the World Health Organization (WHO) warned about a strong possibility of human-to-human transmission and urged precautions. On January 20, the WHO and China confirmed that human-to-human transmission had occurred.

On January 26, 2020, the Centers for Disease Control and Prevention (CDC) confirmed the first case in California. The person, who had returned from travel to Wuhan, China, was released from the hospital in Orange County on February 1 in good condition to in-home isolation. On January 31, the CDC confirmed the state's second case, a man in Santa Clara County, who had recently traveled to Wuhan. The man recovered at home and was released from in-home isolation on February 20. On February 6, 2020, a woman from San Jose, California, became the first COVID-19 death in the U.S., though this was not discovered until April 2020. The case indicated community transmission was happening undetected in the state and the U.S., most likely since December.

February
Newsom announced that,, the number of people being monitored for the virus in California amounted to 8,400.

On February 27, the governor announced that the state was limited in testing for the new coronavirus because it had only 200 testing kits.

March
On March 4, the governor declared a state of emergency after the first death in California attributable to coronavirus occurred in Placer County.

On March 12, Newsom announced that mass gatherings (over 250 people) and social gatherings (more than 10 people) were banned until the end of March. He also issued an order to permit the state to commandeer hotels and medical facilities to treat coronavirus patients. On March 13, schools were closed in Marin, Sacramento, San Joaquin, San Luis Obispo, Santa Clara, Solano, Placer, and Contra Costa counties, as well as the Oakland, Antioch, Santa Cruz, Los Angeles Unified, Chaffey Unified, Etiwanda, Fontana Unified, Ontario-Montclair, Alta Loma Unified, San Diego, Los Alamitos Unified, and Washington Unified school districts. In Santa Clara county, all gatherings of 100 or more people were banned, and gatherings of 35 or more people were banned unless they satisfied public health restrictions. Press reports in April suggest that the aggressive early imposition of social-distancing orders by Santa Clara County were the result of community surveillance performed beginning on March 5.



On March 15, Newsom called for voluntary closure of bars and in-home self-isolation of seniors 65 and older, as well as persons at-risk due to underlying conditions. On March 16, the health officers of Alameda, Contra Costa, Marin, San Francisco, San Mateo, and Santa Clara counties announced, with the City of Berkeley, a legal order directing their respective residents to shelter in place for three weeks beginning midnight March 17 to April 7 in order to slow the spread of the coronavirus. The order limited activity, travel and business functions to only the most essential needs. The same day, the county of Santa Cruz issued a similar shelter in place order.

On March 17, more counties issued shelter in place orders, including Monterey County (until April 4), San Benito (until April 7), and Sonoma (until April 7). The federal Defense Secretary said the military would provide up to 5 million respirator masks and also 2,000 ventilators from its reserve.

On March 18, shelter in place orders were issued by Yolo County (until April 7), the city of Fresno (until March 31), Napa County (effective March 20, until April 7) San Luis Obispo County (until April 17), and Mendocino County (until April 7). The Department of Defense said the Navy's hospital ship USNS Mercy is being prepared for deployment in California, "to assist potentially overwhelmed communities with acute patient care".

On March 19, Newsom then announced a statewide stay-at-home order. Newsom said that the state has asked the Department of Defense to deploy the Navy's USNS Mercy hospital ship in California.

On March 20, Governor Newsom deployed the California National Guard to provide assistance to food banks in California.

On March 21, the Strategic National Stockpile Division of the United States Department of Health and Human Services converted the Santa Clara Convention Center into a Federal Medical Station to receive noncritical patients from local hospitals.

On March 22, President Trump announced that he had directed Federal Emergency Management Agency to provide 8 large federal medical stations with 2,000 beds for California.

On March 24, Newsom passed an executive order to postpone intakes in prisons and juvenile correction centers. The objective was to hinder contamination in the prison system. Also on March 24, the California State Guard was deployed alongside the California National Guard in San Mateo County to provide emergency prehospital response for patients.

April
On April 1, Newsom announced the closure of all public and private schools for the remainder of the 2019–2020 academic year, including all institutions of higher education, and directing all schools to "put all efforts into strengthening our delivery of education through distance learning." The University of California system announced that they would temporarily suspend the use of standardized testing for Fall 2021 admissions, and suspend the letter grade requirement for A-G courses completed in winter, spring, and summer 2020.



On April 7, Newsom announced that the state has secured a deal that will provide upwards of 200 million masks, including 150 million N95 masks, per month to the state.

On April 9, Newsom announced the state would pay for hotel rooms for hospital and other essential workers afraid of returning home and infecting family members.

On April 13, Newsom, together with Oregon governor Kate Brown and Washington governor Jay Inslee, announced the Western States Pact, an agreement to coordinate among the three states to restart economic activity while controlling the outbreak.

On April 15, Newsom announced that undocumented immigrants can receive $500 per adult or $1,000 per household. The total cost will be $75 million that will be distributed by nonprofit organizations.

On April 22, Newsom ordered a review on autopsies of people who died in December 2019 in order to find out when COVID-19 arrived in California.

On April 24, Newsom announced a program that will deliver free meals to elderly residents who meet the program's requirements. This program partners with local restaurants to deliver up to $61 worth of meals per day to each qualified resident. 75% of the program's cost will be covered by FEMA, and the rest will be covered by the state and local governments.

On April 29, Newsom announced an expansion of the state's Farm to Family program, which helps connect farmers to food banks. The governor also announced that the state's CalFresh program will continue to send every recipient the maximum amount of benefits for May. Newsom also said that families with kids who can receive free or low-cost lunch at schools could now get up to $365 a month in additional benefits due to the Pandemic-EBT program. Additionally, Newsom announced that EBT cards could be used to buy groceries online on Amazon and Walmart, and the state was encouraging other supermarkets to also accept EBTs for online purchasing.



May
By May, Newsom had come under pressure to reopen, e.g. via over a dozen lawsuits filed by lawyer Harmeet Dhillon, who later credited herself for "large sectors of California's economy opening up much sooner than the governor originally intended."

On May 2, the Washington Post reported that a vitamins executive claimed that (at a previous time not specified in the article) Trump had given him Newsom's phone number for the purpose of persuading the governor to buy hydroxychloroquine as a proposed treatment for COVID-19. Newsom declined the proposal to buy millions of hydroxychloroquine tablets, at cost, from an Indian manufacturer.

On May 6, Newsom signed an executive order to extend workers' compensation for all workers who contracted COVID-19 during the state's stay-at-home order. This order was to be retroactive to March 19, when the state's stay-at-home order was issued. Newsom also signed an executive order that waived property tax penalties for residents and small businesses that have been negatively affected by the pandemic.

On May 7, Newsom announced that the state was moving into Stage 2 of its four-stage reopening roadmap. Stage 2 allows for certain low-risk sectors of the economy to reopen, so long as there are significant safety measures in place.

On May 8, Newsom signed an executive order to send every registered voter a mail-in ballot for the 2020 general election.

On May 18, the Department of Public Health announced that counties could selectively reopen types of business that are part of Stage 3 of the state's four-stage reopening roadmap. To reopen certain types of business, a county would attest to its readiness.

On May 26, the Department of Public Health announced that hair service businesses could reopen with restrictions.

June
On June 5, the Department of Public Health noted that many counties were ready to move ahead into Stage 3 of the state's four-stage reopening roadmap. Stage 3 allows for certain higher-risk businesses to reopen with safety and hygiene modifications like seating capacity and regular cleaning in restaurants, bars, theaters, gyms and hair salons.

On June 12, the Department of Public Health released guidance for expanding the operations of personal care service businesses.

On June 18, the Department of Public Health issued universal masking guidance. Counties may follow this guidance to require the wearing of cloth face coverings by all individuals over the age of 2 in all public indoor settings, and in outdoor settings when social distancing is not possible. Exemptions are provided for restaurants (if social distancing is maintained), inmates, and people with specific medical conditions that prevent their use. Newsom stated that "science shows that face coverings and masks work".

By late June, The New York Times observed an "alarming surge in cases" in California that was forcing Newsom to roll back the reopening in several counties.

On June 26, Newsom said he was "committed to intervening" if Imperial County officials did not reimpose stay-at-home orders in the Mexican border region where positive rates averaged 23% while the nationwide average was 5.7%.

On June 28, Newsom ordered bars closed in seven counties: Los Angeles, Fresno, Kern, San Joaquin, Tulare, Kings, and Imperial.

July
On July 1, Newsom ordered the closure of most indoor businesses, including restaurants, wineries, and movie theaters, in Contra Costa, Fresno, Glenn, Imperial, Kern, Kings, Los Angeles, Merced, Orange, Riverside, Sacramento, San Bernardino, San Joaquin, Santa Barbara, Santa Clara, Solano, Stanislaus, Tulare, and Ventura counties.

On July 13, Newsom re-imposed the closure of gyms, indoor dining, bars, movie theaters, and museums, citing an increase in cases.

By July 2020, California had the highest number of confirmed cases in the United States. In June, the state surpassed the 200,000 and in July 2020, 300,000 and again, 400,000 mark, about one percent infection rate per population for the state's 40 million residents. When the state rolled back reopening on July 13, the Mexican border county of Imperial was suggested on June 26 by the state government to restore their stay-at-home order.

August
On August 18, San Diego and Santa Cruz were removed from the state watchlist, now consisting of 42 counties. On August 24, Orange, Napa, Calaveras, Mono, and Sierra were removed from the state watchlist.

On August 28, Newsom unveiled the Blueprint for a Safer Economy — a new set of guidelines for lifting restrictions, designed to be "simple, stringent and slow". The Blueprint replaced the state watchlist with a four-tiered, color-coded classification system. These levels are based on the number of daily cases per-100,000 residents, and the current test positivity rate. To progress to a lower level, a county must remain within its required metrics for at least 21 days. A county may be rolled back to a higher tier if its numbers trend into its metrics over a 14-day period. These state orders may still be superseded by stricter county health orders.

Local governments can delay a transition to a lower level as they choose.

Head of Health and Human Services Mark Ghaly stated that "health equity benchmarks" would also be a factor in classifications, with the Department of Public Health listing "data collection, testing access, contact tracing, supportive isolation, and outreach that demonstrate a county's ability to address the most impacted communities within a county" as metrics under this category.

October
In early October, the California government added a new "equity metric" to its Blueprint for a Safer Economy. The equity rule relies on the California Healthy Places Index (HPI), which ranks census tracts in California using 25 factors including median household income, unemployment rate, education, voter turnout, tree coverage, health insurance, alcohol availability, and air and water pollution. For counties with a population above 106,000, the reopening of the entire county depends not only on the countywide infection rate but also on the infection rate within census tracts that score in the lowest quartile on the HPI.

On April 6, Governor Newsom announced that the state planned to end most COVID-19 restrictions on June 15, 2021, if certain criteria are met: this includes equitable vaccine availability for all residents 16 years of age and older, and hospitalizations remaining "stable and low". Newsom justified the decision by stating that California "the lowest case rates [and] positivity rates in America."

Head of Health and Human Services Mark Ghaly stated that California will be focusing on vaccination and mandatory masking as opposed to limitations on businesses moving forward; following this change, the Blueprint will "no longer be in effect" in its present form, and most fields of business will be allowed to operate with few restrictions. These changes will take effect simultaneously state-wide. There will still be some indefinite restrictions; the mask mandate will remain in effect, and the state does not plan to immediately allow large multi-day events such as music festivals (although singular concerts will still be allowed). Furthermore, participation in large-scale indoor events such as conventions will be subject to proof of full vaccination or having recently tested negative, and that such events might not be able to operate at a full capacity without this requirement until October 2021.

December
On December 13, due to the threat of Omicron variant, it was announced that a state-level mask mandate for indoor public spaces would be reimplemented from December 15, 2021, through January 15, 2022, in all counties that did not already have a mask mandate, and regardless of vaccination status. The state order does not override existing mask mandates in counties that already had one prior to December 13, such as Los Angeles County and San Francisco (including provisions that differ from the new state mandate, such as San Francisco exempting "stable groups" of fully-vaccinated individuals from its mask mandate).

Los Angeles metropolitan area
On February 26, 2020, Orange County declared a local health emergency to raise awareness and accelerate emergency planning.

On March 8, 2020, Riverside County declared a public health emergency with a case being treated at Eisenhower Health in Rancho Mirage.

On April 7, 2020, Mayor of Los Angeles Eric Garcetti announced that in accordance with recent CDC recommendations, it would institute a Worker Protection Order beginning April 10, requiring all employees and customers of stores and essential businesses to wear a face mask. Businesses will have the right to refuse service to customers who do not wear a face mask.

On July 15, 2021, due to newfound concerns over the Delta variant and a recent spike in cases, the Los Angeles County Department of Public Health announced a regional mask mandate will be reinstated effective 11:59 p.m. on July 17. This applies in all indoor public spaces, regardless of vaccination status.

On October 6, 2021, the Los Angeles City Council passed the SafePassLA ordinance, requiring proof of full vaccination for patrons of nearly all public indoor spaces, including malls, indoor restaurants and bars, museums, entertainment and recreation facilities, salons, and gyms. It also applies to all outdoor events with more than 5,000 attendees. The ordinance takes effect November 8, and supersedes the separate order issued by Los Angeles County where applicable.

Sacramento metropolitan area
On March 3, 2020, Placer County declared a public health emergency, following the confirmation of a second coronavirus case in that county.

On March 7, 2020, a family in Elk Grove contracted the virus and was quarantined which led to the school district of Elk Grove decision to close down all schools until March 13.

On March 10, 2020, a resident of a retirement home tested positive in Elk Grove in Sacramento County. County health officials said that they had the capacity to only test 20 people per day and would be focusing all their efforts on the other residents of the retirement home. That resident died from complications of the virus on the same day.

On March 17, 2020, Sacramento County issued a stay-at-home directive, which, unlike a shelter in place order, is not a legal requirement.

On March 19, 2020, Sacramento County upgraded its stay-at-home directive into an official order that carries legal consequences.

On October 12, 2021, the Sacramento City Unified School District approved a vaccine mandate for all staff and students age 12+, effective November 30.

San Diego metropolitan area
On February 14, 2020, San Diego County declared a local health emergency to ensure that the county had the resources needed to respond to the infections. The state of emergency lasted for seven days.

On March 10, a woman became the first presumptive case of the novel coronavirus in San Diego County, who was being treated at Scripps Green Hospital, with verification of the test results pending from the CDC. The infection was related to overseas travel; she had not been subjected to a 14-day quarantine upon return, indicating that she did not come from one of the "high risk" countries at the time of her return.

, contact tracers in San Diego had only contacted around 9,000 contacts out of an estimated 170,000 persons who need to be contacted. Some people reportedly become angry when contacted and demand to know who had tested positive. When contact tracers don't reveal this information, sometimes people hang up. They attempt to call them two more times, then mail a letter telling them how to stay safe. They call one more time after a 14-day period to see if the person developed symptoms.
