City of Berkeley COVID-19 data

 

This dashboard provides detailed information about confirmed cases and reported tests for COVID-19 in the City of Berkeley and COVID-19 hospitalizations in Alameda County. It is intended for informational purposes only. Detailed demographic data that include City of Berkeley data is available on Alameda County COVID-19 dashboards.

Note: If the dashboard isn't loading for you, it may be due to your browser security settings. To see the dashboard, turn off "block 3rd party cookies" in your browser settings, or follow this link to open the dashboard in a new window.

Data Sources

The case count and testing data used in this dashboard is available in raw form to view, download, or create your own visualizations on the City's Open Data Portal.

The Alameda County hospitalization data comes from the California Department of Public Health COVID-19 cases dataset, which provides a statewide daily inventory of hospitalization information aggregated to the county level.

Alameda County COVID-19 data

We cannot provide Berkeley-specific demographic or hospitalization data due to personal health privacy restrictions and the small size of our jurisdiction.

We collaborate with the Alameda County Health Department to include Berkeley data in countywide demographic information.

Please note that numbers on the Alameda County dashboard may differ from what is reported on the City of Berkeley's website due to the timing of dashboard updates.

Notes & limitations

Overall limitations

Case counts only reflect lab-confirmed cases, not the total number of people in Berkeley who have been infected with COVID-19. Many people with COVID-19 experience mild or no symptoms, but they can still spread the disease to others. Additionally, many people with symptoms are not included in these numbers due to limitations on testing.

Confirmed cases

The confirmed cases dataset represents the number of new and confirmed COVID-19 positive cases among Berkeley residents, and does not include two cases that were lab-confirmed in early March that were passengers of the Grand Princess cruise.

Counts include cases that are lab-confirmed, and do not include probable or suspect cases. COVID-19 deaths are included in counts. Counts may not include staff and/or patients of healthcare, residential facilities, or other worksites who are not considered Berkeley residents at the time of disease onset.

The dataset begins on the date the first case of COVID-19 was confirmed in the City of Berkeley. 

Testing data

The reported tests dataset represents a weekly count of test results reported among unique Berkeley residents, and how many of those were positive. Reported test results on include tests with a positive or negative result. Counts do not include lab results of two cases that were lab-confirmed in early March that were passengers of the Grand Princess cruise.

Data comes from CalREDIE, California's statewide communicable disease tracking database, and is updated daily. Dates reflect the date created in CalREDIE. Delays in reporting of lab tests occur often due to variation in the time needed to complete and report tests by different laboratories.

Counts for a particular date in the past may change as data is updated in CalREDIE.

The percent positive by week may also vary greatly when the number of total tests completed are small. 

On March 24, 2020, the Health Officers of six Bay Area counties and the City of Berkeley mandated that all laboratories report all COVID-19 test results to the public health department through CalREDIE. Testing numbers before this mandate was issued are not comprehensive of all COVID-19 tests completed. Tests with the negative results before this time may not have been reported through CalREDIE, and it is not anticipated that negative lab results will be added back retroactively. However, counts are always subject to change as information is updated in CalREDIE.

Note that the percent positive for week 9 (the first week reported in the dataset) was 100% because only one test was completed during that week. During weeks 9 and 10, COVID-19 testing was limited, and was only being conducted at public health laboratories. Commercial testing began to occur during week 11 and has continued increasing since this time.
