The COVID-19 pandemic has spread rapidly across California. Experts say the true number of people infected is unknown and likely much higher than official tallies.
To better understand the spread of the virus, The Times is conducting an independent, continual survey of dozens of local health agencies across the state.
What we know
New cases have plateaued. New cases are holding near levels seen in the spring. Over the last seven days, the state averaged 4,402 cases per day, with 3.3% of tests coming back positive.
Death tallies are dropping. The state has averaged 55.7 daily deaths over the last week.
The state is slowly easing the lockdown. The governor’s system now rates 12 counties as too risky to reopen, including Los Angeles County. Other areas have begun to ease restrictions.
Disparities in age and race persist. Roughly 74% of the dead were 65 or older. After adjusting for population, Latinos are now 3.3 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.
The number of cases in California is now on pace to double every 134.7 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 4,402 new cases and 55.7 new deaths per day.

The lines above are seven-day averages. They offer a more stable view of the trend than daily totals. The gray range marks 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 counties to determine when and how businesses reopen. After adjusting for population, the virus is now categorized as widespread in 12 counties, keeping those areas largely locked down. Together they are home to 42% of California residents.
The government doesn't release enough data to replicate its analysis, but the rate of new cases over the last seven days provides some insight into where the virus is spreading.

Hospitals and patients
Lockdown measures aim to slow the virus in hope of preventing hospitals from being overrun. To keep tabs on capacity, officials watch out for rapid increases in the number of patients.
There are now 2,254 hospital patients statewide with a confirmed case, a change of 2% from two weeks ago.

Latinos and Black people have contracted the virus at a higher rate than white and Asian people. After adjusting for population, Latinos are now 3.3 times more likely to test positive than white people.

California in context
To date, the United States has recorded 8,569,586 coronavirus cases and 224,794 deaths. In the last week, the country has averaged 66,904 new cases and 803 deaths per day.
While California — America’s most populous state — leads the nation in cases, it ranks much lower after adjusting for population. Home to 12% of the country's population, thus far it has accounted for roughly 11% of cases.

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 California's Department of Public Health.
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.
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.
