To better understand the COVID-19 pandemic, The Times is conducting an independent, continual survey of dozens of local health agencies across the state.
What we know
Stay-at-home orders remain. Most of the state, including Los Angeles County, is currently under stricter rules.
New cases have been surging. Over the last seven days, the state has averaged 44,795 cases per day, a significant jump from before the holidays. Roughly 13.9% of tests this past week have come back positive.
Deaths are on the rise. The state has averaged 480.9 daily deaths over the last week, an increase of 108.8% from two weeks ago.
Hospitalizations have never been higher. Statewide, there are 21,647 people hospitalized with a confirmed case, 13% more than two weeks ago. Check the status of facilities with The Times' new hospital tracker.
Disparities in age and race persist. Roughly 75% of the dead were 65 or older. After adjusting for population, Latinos are now 2.6 times more likely than whites to test positive.

The latest totals
Coronavirus can infect people so rapidly that it has continued to spread despite shutdown orders aimed at slowing the growth of new cases and flattening the line below.
So far, 1 out of every 15 people in the state has tested positive. The number statewide is now on pace to double every 43.8 days, a number used to measure how quickly the virus is spreading.

Times survey of county and local health departments
Local governments announce new cases and deaths each day, though bottlenecks in bureaucracy can introduce delays. For instance, some agencies do not report new totals on holidays and weekends, leading to lower numbers on those days.
Over the past week, the state has averaged 44,795 new cases and 480.9 new deaths per day. Experts say the true number of people infected is unknown and likely much higher than official tallies.

Seven-day averages offer a more stable view of the trend than daily totals. On the cases chart, gray bars mark when errors in a state computer system delayed the tabulation of new cases.

Where new cases are concentrated
State officials study the latest data and then rate regions and counties to determine when and how businesses reopen.
The government doesn‘t release enough data to replicate its analysis, but the rate of new cases per 100,000 residents over the last seven days provides insight into where the virus is spreading.

Hospitals and patients
Stay-at-home orders aim to slow the virus in hope of preventing hospitals from being overrun. To keep tabs on available beds, officials watch out for rapid increases in the number of patients.
There are now 21,647 hospital patients statewide with a confirmed case, a change of 13% from two weeks ago.

Officials have organized the state’s counties into five regions. If a region’s available percentage of intensive-care beds falls below 15%, a stay-at-home order is issued. The number is adjusted to ensure that some beds remain open for patients who don’t have COVID-19. Four regions currently fail.

Vaccines
About 2.06 million doses of coronavirus vaccine have been shipped to California counties and healthcare systems. To date, a total of 734,405 shots of the two-dose vaccine have been administered. The state public health department has not released the total number of people vaccinated.
The first inoculations are being administered to healthcare workers who face the greatest exposure to the virus and residents of long-term care facilities, such as nursing homes. Officials are still drafting a plan on how to roll out the vaccine beyond the initial group. It is unclear when essential workers and other Californians will have access.
Phase 1
Healthcare workers and long-term care residents
Doctors and nurses on the front lines are now receiving shots. Other healthcare workers and nursing homes come next in this step.
Phase 2
Essential workers
Emergency personnel, teachers and farmworkers are expected to be next in line. There is no start date. Who else will qualify is undecided.
Phase 3
Everyone else
It’s unclear how long the rest of California’s nearly 40 million residents may wait. Experts say shots may be readily available by late spring or summer.
Testing
After a fitful start, California has increased coronavirus testing in the state. Over the last week, an average of 287,720 tests have been conducted each day.

The state has logged the race of the patient in nearly two-thirds of cases.
Latinos and Black people have contracted the virus at a higher rate than white and Asian people. After adjusting for population, Latinos are now 2.6 times more likely to test positive than white people.

One outcome is that among most age groups, and especially younger people, Black people and Latinos are dying more often than other races relative to their share of the population.

California in context
To date, the United States has recorded 22,170,821 coronavirus cases and 372,354 deaths. In the last week, the country has averaged 246,533 new cases and 3,172 deaths per day.
While California — America’s most populous state — has the nation’s top case counts. Home to 12% of the country's population, thus far it has accounted for roughly 12% of cases.

About the numbers
This page was created by Swetha Kannan, Casey Miller, Sean Greene, Lorena Iñiguez Elebee, Rong-Gong Lin II, Ryan Murphy, Melody Gutierrez, Priya Krishnakumar, Sandhya Kambhampati, Maloy Moore, Jennifer Lu, Aida Ylanan, Vanessa Martínez, Ryan Menezes, Thomas Suh Lauder, Andrea Roberson, Ben Poston, Nicole Santa Cruz, Iris Lee, Rahul Mukherjee, Jaclyn Cosgrove, Anthony Pesce, Paul Duginski and Phi Do.
State and county totals come from an ongoing Times survey of California’s 58 county health agencies as well as the three run by cities. Those figures are ahead of the totals periodically released by the state’s Department of Public Health. State officials acknowledge that their tallies lag behind the updates posted by local agencies throughout the day and do not dispute The Times’ method.
Data on hospitalizations, tests, demographics and reopening plans come from the state health department.
Nursing home totals include skilled-nursing facilities tracked by the state public health department, as well as assisted-living facilities monitored by the California Department of Social Services.
Data from other states, Washington, D.C. and Puerto Rico are collected by researchers at the Johns Hopkins University Center for Systems Science and Engineering.
Counties are organized into regions using the groupings developed by the state health department.
The Times database is available to the public on Github, a popular website for hosting data and computer code. The files will be updated daily at github.com/datadesk/california-coronavirus-data.
The data collection effort is done in partnership with journalists at the San Francisco Chronicle, the San Diego Union-Tribune, KQED, KPCC, CapRadio, Calmatters and Stanford’s Big Local News.
Learn more about The Times count by reading this list of frequently asked questions or by reading this interview with members of our team.
