The San Francisco Bay Area, which includes the major cities of San Jose, San Francisco, and Oakland, was an early center of the COVID-19 pandemic in California.[2] The first case of COVID-19 in the area was confirmed in Santa Clara County on January 31, 2020.[3] A Santa Clara County resident (with no foreign travel history) was the earliest known death caused by COVID-19 in the United States, on February 6,[4] suggesting that community spread of COVID-19 had been occurring long before any actual documented case. This article covers the 13 members of ABAHO, which includes the nine-county Bay Area plus the counties of Monterey, San Benito, and Santa Cruz.
Local officials instituted some of the first mitigation efforts in the United States. The first mandatory stay-at-home order in the mainland U.S. took effect throughout the Bay Area on March 16 and 17 and continued until mid-May,[5] affecting nearly 6.7 million people.[6] The early government response is credited with mitigating the spread of infection compared to cities on the East Coast.[2][7]
Closures due to the pandemic have resulted in mass unemployment and significant disruptions to the economy, replacing local governments' budget surpluses with historic deficits. The pandemic accelerated the adoption of distance education among schools and remote work among businesses, especially in the technology industry. Air quality around San Francisco Bay improved as a result of a temporary decline in traffic volume.
^Cumulative cases reported by each county's health department. Cases reported are those of county residents, including those who tested positive elsewhere in California.
^Counties differ in what they consider to be a recovery.
^Including cases in the City of Berkeley, which are reported by the Berkeley Public Health Division.
Despite strong economic, cultural, and travel ties between California and China, the Bay Area's hospitalization rate and death toll have stayed below initial projections and have compared favorably to East Coast cities. Researchers have hypothesized that the pandemic's initial impact was blunted by relatively early social distancing measures along with a variety of other factors, including lower population density, a strong car culture and low public transportation ridership, favorable weather in February, and even a loss by the San Francisco 49ers at Super Bowl LIV, discouraging celebrations.[2][7]
As of May 26, 2020[update], the nine counties of the Bay Area plus Santa Cruz County have reported a cumulative total of 13,060 confirmed cases and 434 confirmed deaths due to COVID-19. Alameda County has more confirmed cases and deaths than any other county in Northern California, followed by Contra Costa County. Some counties have released breakdowns of cases by jurisdiction.[17] In Alameda County, Hayward has the highest per capita rate of infection at 270.2 people per every 100,000, while Oakland has the highest number of cases. San Mateo and San Jose have the highest number of cases in San Mateo and Santa Clara counties, respectively.[18]
As of May 17, 2020[update], the North Bay counties of Marin, Napa, and Sonoma have reported a cumulative total of 345 recoveries from COVID-19. The other Bay Area counties do not report the number of recoveries, because tracking this number requires more resources per case and federal guidelines are not specific enough to draw conclusions. A study at the University of California, San Francisco (UCSF), is tracking outcomes several months after infection.[19]
The Hispanic population in the Bay Area has been disproportionately affected by infections. The poor, largely Latino neighborhoods in East San Jose account for 34% of Santa Clara County's first deaths due to COVID-19 despite being Latinos making up only 23% of the adult population. Almost 70% of the neighborhoods' working-age population is unable to remote work.[20][21]Filipino Americans in the Bay Area have also been disproportionately affected by COVID-19 infections, and make up the majority of cases in San Mateo County, California.[22] In San Francisco, about 40% of Hispanics have been confirmed infected, compared to 15% of the general population. The largely Latino Mission District has the highest number of cases of any neighborhood, with more than 40 cases per 10,000 residents.[18] UCSF systematically tested 2,959 residents in a 16-block census tract in the Mission District in April, finding that 2% tested positive. Infection rates differed significantly between essential workers and residents who were able to stay at home during the pandemic.[23]
Localized outbreaks of COVID-19 have occurred at factories and care facilities, including the Tesla factory in Fremont where over 130 people tested positive,[24] the Lusamerica Foods fish packing plant in Morgan Hill where 38 people tested positive,[25] the Central Gardens skilled nursing home in San Francisco's Western Addition where four residents died,[26] and the Windsor Vallejo Care Center in Vallejo where more than 130 people became infected and eleven residents died.[27]
The number of confirmed cases is believed to fall significantly short of actual infection rates due to limited testing capacity throughout the pandemic.[28] As of May 20, 2020[update], San Francisco has collected 5,000 tests for every 100,000 residents, while Santa Clara County has collected about 2,600 tests for every 100,000 residents. Santa Clara County set up three testing sites in San Jose, but the sites are operating well below capacity, in part because of Spanish- and Vietnamese-language barriers.[29]
Several local studies have attempted to determine seroprevalence in the absence of widespread clinical testing. Based on serology tests in early April, a revised preprint study from Stanford University estimated that Santa Clara County up to 54,000 residents, or 2.8% of the population, had been infected, compared to the 1,000 confirmed cases at the time. In an earlier preprint, the study's authors had estimated an even higher rate of infection but therefore calculated a lower mortality rate. Despite academic controversy over the study's methodology, which prompted the revision, the preprint fueled opposition to stay-at-home orders in the United States.[30][31][32][33] The university has begun an investigation into the study.[34] In addition to its study in San Francisco's Mission District, UCSF is conducting a similar study of all 1,680 residents in the rural community of Bolinas, and the University of California, Berkeley, is testing a representative sample of 5,000 East Bay residents.[32]
There has been speculation that COVID-19 may have been circulating in the Bay Area by December 2019. Ongoing "lookback studies" are attempting to identify the index case. An initial preprint of a study at Stanford University Medical Center has found no infected samples from November and December 2019.[36] As of February 14, 2021[update], the earliest known cases in Santa Clara County have been dated to January 27, 2020.[1]
On January 31, 2020, the Centers for Disease Control and Prevention (CDC) announced the first confirmed case of COVID-19 in the Bay Area and the seventh in the United States, a man in Santa Clara County who had recently traveled to Wuhan.[3] The man recovered at home and was released from in-home isolation on February 20.[37] On February 2, the CDC confirmed a second area case in a Santa Clara County woman who had also recently traveled to Wuhan. The two cases were unrelated.[38]
On February 6, 2020, 57-year-old Patricia Dowd of San Jose died of COVID-19 without any known recent foreign travel. She had been unusually sick from the flu in late January, then recovered, remote worked, and suddenly died at home on February 6. A February 7 autopsy[39] was completed in April (after virus tests on tissue samples) and attributed the death to transmural myocardial ischemia (infarction) with a minor component of myocarditis due to COVID-19 infection.[40] Her case was discovered in April 2020; from then until August 2021, she was considered to have been the first COVID-19-related death in the U.S.[41] It indicated that community transmission was happening undetected in the U.S., most likely since December 2019.[42][43][44][45]
On February 26, 2020, a case of unknown origin was confirmed in a resident of Solano County.[46][47] 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.[48]
After this first case of community transmission in the U.S.,[49] the CDC revised its criteria for testing patients for SARS-CoV-2 and, on February 28, began sending out the new guidelines for healthcare workers.[50][51]
The first case of the Omicron variant detected in the United States was also located in the Bay Area. A resident of San Francisco returned from South Africa on November 22, 2021, began showing mild symptoms on November 25, and was confirmed to have COVID-19 on November 29. The individual had been vaccinated but had not received a booster shot.[52][53]
A public safety alert sent on March 16 by Santa Clara County about the shelter-in-place orderAs of April 7, the Santa Clara County Public Health Department and Stanford University School of Medicine projected that the county would have had several times more cases of COVID-19 by May without the regional and state shelter-in-place orders.Market Street, San Francisco, on Memorial Day 2020
The Bay Area public health response to the pandemic is being coordinated through the Association of Bay Area Health Officers (ABAHO), an organization consisting of the public health officers of 11 counties and two cities that was established in the 1980s to fight the AIDS epidemic in San Francisco.[54][55] The health officers act in unison to avoid political pushback. ABAHO is informally divided between the "Big Seven", consisting of Alameda, Contra Costa, Marin, San Mateo, and Santa Clara counties and the cities of Berkeley and San Francisco; and Santa Cruz, Monterey, Napa, San Benito, Sonoma, and Solano counties on the periphery of the Bay Area.[55]
Unlike the shelter-in-place order, orders to wear face coverings such as cloth face masks while in public took effect at different times depending on the jurisdiction.

The Innovative Genomics Institute at the University of California, Berkeley, headed by Dr. Jennifer Doudna converted the genomic-editing research laboratory to run COVID-19 tests. Despite a widespread need for COVID testing, doctors and hospitals were hesitant to use the newly set up labs in favor of major commercial laboratories like LabCorp and Quest.[119]
As in other parts of California and the United States, the Bay Area has experienced a dramatic increase in unemployment as a result of voluntary and mandatory social distancing measures. In April 2020, unemployment in the Bay Area increased by 555,100 residents or 13.7% month over month, including a 15.1% increase in private-sector job losses.[120]
Unemployment has affected the Bay Area unevenly from one area or industry to another.[120] Despite layoffs by startups in March and April,[121] job losses in the technology industry increased by only 4.1%, compared to an increase by more than 50% in the hospitality industry. Due to the technology industry's dominance in Santa Clara County known as Silicon Valley, unemployment increased by only 11.2% there in April, compared to 14.6% in the East Bay and 14.4% in San Francisco and San Mateo County.[120] In San Francisco, which is relatively dependent on tourism, over 100,000 residents, or about one-ninth of the city's population, filed for unemployment benefits during the pandemic.[122]
As of May 13, 2020[update], large Bay Area employers have collectively sent the state Employment Development Department about 24,700 WARN notices about proposed mass layoffs, furloughs, or facility closures.[123]
Signs of community support in front of the popular Sushi Sam's restaurant in San Mateo posted in May 2020
Bay Area counties' strict interpretations of shelter-in-place orders halted most residential and commercial construction projects.[124] Some construction projects resumed in mid-May.[125]
San Francisco has tentatively projected that its deficit will double to between $1.1 billion and $1.7 billion over fiscal years 2020 and 2021.[126]
Redwood City expects to have a balanced budget in 2020 but a $10 million deficit in 2021.[127]
As of May 2020[update], San Jose projects a $45 million deficit for fiscal year 2019–20 and a $71.6 million deficit for 2020–21, revised downward from a $500,000 surplus projected in 2019. The impact will be significantly worse than either the dot-com bust or the Great Recession.[128][129]Palo Alto projected a $40 million loss in revenue.[130]
Oakland projected a $80 million deficit over 14 months and has laid off part-time employees.[126]Berkeley projected a $2.6 million deficit in 2020 and a $25.2 million deficit in 2021.[127]
Richmond projected a $7 million deficit in 2020 and a $27 million deficit in 2021. Walnut Creek closed a $13 million budget gap in 2020 but expects a $12 million deficit in 2021.[127]
Some major Bay Area manufacturers, such as Lockheed Martin in Sunnyvale and Chevron Corporation in San Ramon, have been exempted from shelter-in-place orders as essential businesses. However, the Tesla Factory in Fremont was not exempted and was forced to halt production, resulting in the furlough of nearly 11,100 employees.[123] On May 11, Tesla resumed manufacturing operations at the factory despite an Alameda County order allowing only minimum basic operations.[131]

The March 13 announcement of a shelter-in-place order triggered a wave of panic buying throughout the region.[132]
By April, the Consumer Price Index for the San Francisco area (Alameda, Contra Costa, and Marin counties and San Francisco) fell by 0.5% compared to February, a 1.1% rise year over year. By category, retail prices rose by 14.5% year over year for meat, 9.6% for dairy, 6.7% for food at home (bought in stores), and 0.6% for alcohol. Retail prices fell by 28.4% for regular unleaded gas, 27.6% year over year for motor fuel in general, 12% for clothing, and 7.8% for transportation.[133]
Of the San Jose Downtown Association's more than 1,600 member businesses, 83% are temporarily or permanently closed, 9% are operating with reduced service, and 8% are fully operational as of mid-May.[134]
Due to the pandemic, the Pleasanton-based Specialty's bakery-café chain, which specialized in corporate catering, permanently closed its more than 50 locations on May 19, 2020, after 33 years in business.[135]San Jose–based Fry's Electronics also blamed the pandemic for its closure on February 24, 2021.[136]
The technology industry was not as heavily impacted by stay-at-home orders as the leisure and hospitality industries. Demand for Bay Area–based teleconferencing and e-commerce services increased significantly during the pandemic.[137] According to San Jose–based Zoom Video Communications, usage of its Zoom software rose to 300 million active users, compared to about 10 million per day in December 2019.[138]
By early March, many large technology companies began encouraging or requiring employees to remote work.[139] These social distancing measures, which predated mandatory shelter-in-place orders, are credited with helping to lessen the initial impact of the pandemic.[121][2]
The RSA Conference was held in February as scheduled, but Verizon, AT&T, and IBM pulled out of the conference on February 21, as concerns began to grow about the pandemic.[150]
San Francisco's economy is heavily dependent on tourism, which normally employs 90,000 people and generates more tax revenue than any other industry in the city. International tourism normally accounts for 64% of San Francisco's tourism spending but has largely disappeared during the pandemic.[144] San Francisco's destination marketing organization is projecting visitor volume to recover to 18.4 million for 2021, still down 30 percent to 2019. Gradual improvement will be driven primarily by domestic visitation. International tourism will take much longer to recover.

On April 1, school superintendents in Santa Clara and San Mateo counties announced that in-person classes would not resume during the 2019–20 school year.[151]
Many Bay Area colleges and universities have announced plans for instruction in response to the pandemic:[152]
Educational institutions by 2020–21 school year reopening plans
On February 15, 2022, three commissioners of the San Francisco Board of Education were recalled in the city's first recall election in 39 years. The school board's decision to keep schools closed longer than other major school districts was cited as a factor in the successful recall effort.
Over the first 10 weeks since the shelter-in-place order was issued, Bay Area food banks have seen demand double and calls increase a thousandfold. According to Second Harvest of Silicon Valley, the number of residents needing food distribution increased 40% from 270,000 in February to 370,000 in April. The Alameda County Community Food Bank has distributed over a million of pounds of food a week and seen lines stretching more than 1,000 cars in a day.[180]
A "safe sleeping village" at San Francisco's Civic Center organized tents into an evenly spaced grid as a safer alternative to the city's usual homeless encampments.
An ongoing housing shortage in California has increased housing costs dramatically and contributed to the Bay Area's high rates of homelessness.[20] Homeless shelters have been major sites of community transmission. On April 10, 70 of 144 occupants of one homeless shelter in San Francisco were confirmed to have COVID-19.[181]
By April, the number of tents and makeshift structures increased by 71% over the previous quarter in San Francisco and by 285% in the Tenderloin neighborhood specifically.[182] As of May 3, 2020[update], San Francisco has leased 2,700 hotel rooms as emergency housing for at-risk homeless people and first responders. Although the state government has reserved hotel rooms throughout the state for similar purposes, homeless people have come to the city from other areas looking for hotel rooms, prompting Mayor London Breed to focus the city's emergency housing resources on local homeless people.[183]
There are nearly 6,200 homeless people in San Jose, most of them Hispanic or African American. At least 2,500 are considered at high risk for infection due to underlying health conditions. The city added more than 400 temporary beds at homeless shelters, including a temporary shelter near the San Jose Convention Center. In mid-March, shortly after the shelter-in-place order took effect, the Governor's Office of Emergency Services delivered 104 trailers to a property near Happy Hollow Park & Zoo to use as emergency housing. After repairs, 90 trailers began accepting occupants on May 14.[184]
Sunnyvale – until the local health emergency expires[187]
San Jose temporarily modified its rent control ordinance to place a moratorium on rent increases through the end of 2020, affecting tens of thousands of apartment buildings and mobile home parks.[189] Oakland also extended a 3.5% limit to rent increases until June 30.[186]
In the first week of the shelter-in-place order, Bay Area Rapid Transit (BART) ridership fell by 87% to 89% of average ridership in February, though it had already begun falling with technology companies' transition to remote work. Ridership in April and early May stayed between 90% and 94% below the baseline average. BART suspended late weekday night service on March 23, 2020, and reduced weekend service on March 28, 2020. Beginning April 8, BART reduced weekday train frequency by half and ran only long train consists to facilitate social distancing.[196][194] To prepare for commuters' return to BART, the system accelerated its adoption of contactless payment, eliminating paper ticket vending machines in favor of Clipper card vending machines at several stations and expanding its mobile application's parking payment feature to all stations.[197]
Caltrain's ridership dropped by 75% in the first half of March, prior to the Bay Area–wide shelter-in-place order taking effect,[198] then dropped further to only five percent of normal levels, resulting in losses of $9 million per month.[199] Due to low ridership, Caltrain suspended Baby Bullet service on March 13. On March 26, it further reduced weekday service from 92 trains per day to 42, suspending Limited service.[198]
The Peninsula Corridor Joint Powers Board, which operates Caltrain, had been planning to propose a one-eighth-cent sales tax for voter approval later in the year, to provide an estimated $108 million of dedicated funding for the system, which currently relies on rider fares for 70% of its revenue. In July, after the San Francisco Board of Supervisors initially declined to consider the ballot proposal, citing concerns about the system's governance structure, Caltrain officials warned that the agency would run out of operating funds and be forced to suspend service by the end of the year.[199][200][201] In August, San Mateo County officials agreed to make Caltrain more independent from SamTrans in exchange for places the sales tax on the ballot.[202] In June 2021, Caltrain announced that electric service would be delayed to late 2024 partly due to supply chain disruptions during the pandemic.[203]
On March 21, state-owned toll bridges in the Bay Area stopped accepting cash in favor of open road tolling via FasTrak and paying by plate. FasTrak also temporarily suspended late fees and collections.[206]

Several peaceful protests took place in the Bay Area during the pandemic to raise awareness about police brutality. One in San Mateo on June 3, 2020, was attended by hundreds of people.[212] A youth-led protest against police brutality in San Francisco attracted at least 10,000 protesters to the Mission District.[213]
On March 13, 2020, the Roman Catholic Diocese of San José closed all diocesan schools from until at least April 20. It suspended public Masses and dispensed with the obligation to attend Mass from March 14 until further notice.[216] The Diocese of Oakland also suspended public Masses on March 16, and the Archdiocese of San Francisco and Diocese of Santa Rosa followed suit on March 17.[217] On March 18, the California Catholic Conference of bishops suspended the public celebration of Mass throughout the state until further notice.[218]
On May 23, 2021, the Diocese of Santa Rosa lifted the dispensation from obligation to attend Sunday Mass.[219] The Archdiocese of San Francisco also lifted the dispensation on June 24,[220] followed by the Diocese of Oakland on August 15.[221] On February 8, 2022, the Diocese of San José announced that the dispensation would be lifted effective March 6.[222]
After Santa Clara County banned all large gatherings larger than 1,000 people for a three-week period beginning March 11, the San Jose Sharks of the NHL and the Golden State Warriors of the NBA announced that all of their remaining home games of the regular season would be played behind closed doors with no spectators. With their game on March 12 against the Brooklyn Nets, the Warriors were to be the first professional sports team in the United States to play a home game behind closed doors due to the pandemic, before the NBA suspended the season one day prior.[223][224]
Stanford University announced plans to cut 11 of its 36 varsity sports at the end of the 2020–21 school year, citing a $70 million deficit due to the pandemic.[226]
Mass vaccination sites were opened across the region in February 2021. The first three mass vaccination sites were located at the Oakland Coliseum, the Moscone Center and City College.[237]
The Santa Clara County Public Health Department administered 1.9 million vaccinations, about a third of all vaccinations in the county, at a cost of $1 billion. At the peak of the pandemic, the department operated one of the largest vaccination sites in the United States, serving about 14,000 patients per day at Levi's Stadium. Other vaccination sites, including those at the Santa Clara County Fairgrounds and San Antonio Shopping Center, are scheduled to operate until the end of the public health emergency on February 28, 2023.[238]
The Bay Area–wide shelter-in-place order resulted in significant a reduction in road traffic volume, the main source of air pollution in the area.[239] During the first week after the shelter-in-place order took effect, air pollutant levels fell by one-third year over year, while nitrogen dioxide levels in the atmosphere dropped by roughly half compared to the previous week.[240] Traffic on the San Francisco–Oakland Bay Bridge fell by about 40% compared to two weeks earlier.[241] By April, traffic in the Bay Area had decreased by 70%.[242] An 11% reduction in shipping traffic at the Port of Oakland could have also contributed to air quality improvements.[239] An assistant professor of earth system science at Stanford University estimated that improved Bay Area air quality during the shutdown would result in roughly 10 fewer deaths caused by air pollution per week.[243] According to Save the Bay, the decrease in traffic volume also led to decreased water and noise pollution in and around San Francisco Bay.[244] However, traffic volumes and congestion may return to normal levels or worse after the shelter-in-place orders are lifted, due to the avoidance of public transportation.[245]
Disposable, non-biodegradable face masks and latex gloves used during the pandemic have been discarded on sidewalks and in lakes, raising concern about new sources of litter going into the San Francisco Bay at a time when fewer volunteers are available to pick up litter.[246][247]
