Gov. Gavin Newsom, a Democrat, will increase outdoor gathering limits and will allow indoor live events, beginning April 15. Rules will vary according to the county risk tiers. Mr. Newsom announced that risk tiers and business restrictions will be lifted June 15 if hospitalization levels are low and vaccine supply is sufficient.

About this data Sources: State and local health agencies (cases, deaths); U.S. Department of Health and Human Services (tests, hospitalizations). The seven-day average is the average of a day and the previous six days of data. Currently hospitalized is the most recent number of patients with Covid-19 reported by hospitals in the state for the four days prior. Dips and spikes could be due to inconsistent reporting by hospitals. Hospitalization numbers early in the pandemic are undercounts due to incomplete reporting by hospitals to the federal government. Tests represent the number of individual P.C.R. viral test specimens tested by laboratories and state health departments and reported to the federal government.

Outbreak clusters

Since March 2020, The Times has paid special attention to cases in the types of places with some of the worst outbreaks, like nursing homes, food processing plants and correctional facilities.

Cases Connected To Location Cases
University of California, Los Angeles Los Angeles, Calif. 2,790
San Diego State University System San Diego, Calif. 2,210
University of Southern California Los Angeles, Calif. 1,576
University of California, San Diego San Diego, Calif. 1,473
California Polytechnic State University, San Luis Obispo San Luis Obispo, Calif. 1,371
University of California, Berkeley Berkeley, Calif. 970
University of San Diego San Diego, Calif. 681
University of California, Irvine Irvine , Calif. 612
University of California, San Francisco San Francisco, Calif. 454

About this data Information on cases linked to these places comes from official releases by governments, companies and institutions directly. The Times is publishing lists of groupings of 50 or more cases related to a specific site, workplace or event.

About the data

In data for California, The Times primarily relies on reports from the state, as well as health districts or county governments that often report ahead of the state. California typically releases new data each day. Weekend counts may be lower because fewer sources report to the state. The state reports cases and deaths based on a person*s permanent or usual residence.

The Times has identified the following reporting anomalies or methodology changes in the data:

  • March 13, 2021: California made data adjustments resulting in a one-day increase in deaths.
  • Feb. 24, 2021: Los Angeles County added many deaths from December and January after reviewing vital records.
  • Dec. 16, 2020: California announced a backlog of about 12,000 cases from previous days.
  • July 1, 2020: California added a number of cases from a testing backlog.
  • New cases reported during the first two weeks of August were artificially low while the state resolved a technical issue with its data system. Some counties temporarily stopped reporting new data during this time.
  • Counts for Alameda County include cases and deaths from Berkeley and the Grand Princess cruise ship.

The tallies on this page include probable and confirmed cases and deaths in some counties.

Confirmed cases and deaths, which are widely considered to be an undercount of the true toll, are counts of individuals whose coronavirus infections were confirmed by a molecular laboratory test. Probable cases and deaths count individuals who meet criteria for other types of testing, symptoms and exposure, as developed by national and local governments.

Governments often revise data or report a single-day large increase in cases or deaths from unspecified days without historical revisions, which can cause an irregular pattern in the daily reported figures. The Times is excluding these anomalies from seven-day averages when possible.
